Thermal Insulation of Industrial Tanks: Heat Loss, Condensation, and Inspection Accessibility

Summary: Thermal insulation for industrial tanks is not just about reducing energy loss. In metal tanks, it is also necessary to consider condensation, the risk of Corrosion Under Insulation (CUI), exposure to atmospheric agents, and the need for periodic inspections of the structure. Thin-film nanotechnological insulating coatings represent an interesting solution, especially when complex geometries, limited space, and maintenance requirements make bulky insulation systems impractical.

Spray application of thermal insulation coating Aes Techon an industrial metal storage tank

Spray application of the thin-layer thermal insulation coating Aes Tech on the metal surface of an industrial storage tank.

Why Thermal Insulation of Industrial Tanks Requires a Specific Approach

A storage tank is not simply a large metal surface to be insulated. The temperature of the contained product, external weather conditions, solar exposure, humidity, thermal cycles, and maintenance requirements make every intervention unique.

Therefore, thermal insulation of industrial tanks must be evaluated by simultaneously considering heat loss or heat gain containment, surface protection, and subsequent inspection needs.

In tanks containing hot products, limiting outward heat flux helps maintain a more stable process temperature. Conversely, in tanks containing cold products, the goal is often to restrict heat entry from the surrounding environment and control the conditions that favor condensation formation.

Savenergy.it’s thin-film nanotechnological insulation solutions are applied to liquid tanks, return tanks, boilers, condensate lines, heat exchangers, and storage silos.

Heat Loss: It Is Not Just About Thickness

When a temperature difference exists between the tank’s contents and the outside environment, heat transfer inevitably occurs.

On large structures, even a relatively low heat loss per square meter can become significant when considering the total surface area of the tank.

For this reason, insulation evaluation should not stop at material thickness alone. System thermal characteristics, operating temperatures, solar radiation, metal substrates, exposure conditions, and coating continuity must also be taken into account.

Savenergy.it industrial solutions utilize coatings containing hollow ceramic microspheres and are designed to achieve thermal protection with very low thicknesses. AES Tech, for example, has an application thickness of approximately 1–4 mm.

The advantage of a low thickness becomes particularly compelling in complex areas: joints, supports, welds, connections, and irregularly shaped surfaces.

Condensation on Tanks: When Does It Form?

A second critical issue is condensation.

When the temperature of a metal surface drops below the dew point of the surrounding air, water vapor can condense on the surface.

In an industrial facility, this condition must not be overlooked. The prolonged presence of moisture near the metal creates favorable conditions for corrosive phenomena.

The issue escalates when water penetrates underneath an insulation system and remains trapped between the insulation and the metal surface.

Corrosion Under Insulation: The Problem of CUI

This is where Corrosion Under Insulation—commonly referred to by the acronym CUI—comes into play.

CUI is the corrosion that develops on metal surfaces beneath an insulation system. It is particularly insidious because the degradation may not be immediately visible from the outside.

AMPP emphasizes that moisture, insulation condition, protective coatings, thermal cycles, and outer jacket integrity are all key factors to consider when managing CUI risk.

The topic is significant enough to be addressed by API Recommended Practice 583 – Corrosion Under Insulation and Fireproofing, which reached its third edition in 2026. This Recommended Practice covers design, maintenance, inspection, and CUI mitigation, and explicitly includes storage tanks among the affected equipment.

Corrosion under insulation (CUI): comparison between traditional insulation and Savenergy.it nanotechnological coating on an industrial tank

Comparison between traditional tank insulation and a Savenergy.it nanotechnological coating applied directly to the metal surface, highlighting differences related to moisture, CUI and inspection accessibility.

Traditional Insulation Systems and Corrosion Risks

Traditional insulation systems can promote corrosion, as water and contaminants frequently manage to penetrate the system and reach the underlying metal.

Industrial Tank Thermal Insulation and Inspection Accessibility

This aspect is sometimes overlooked when choosing an insulation system. An industrial tank must remain accessible for inspection and ongoing maintenance.

Comparison between traditional insulation and Savenergy.it nanotechnological coating for inspection accessibility on an industrial tank

Technical comparison between traditional insulation and Savenergy.it nanotechnological coating, highlighting inspection accessibility on industrial tanks and critical components.

Traditional insulation systems can comprise multiple elements—insulating material, fasteners, moisture barriers, and external cladding—and, depending on the required inspection type, localized opening or removal may be necessary to reach the underlying metal surface.

A thermal insulation coating applied directly to the substrate transforms this scenario: it creates no hidden cavity between the insulation panel and the sheet metal, leaving the tank’s geometry immediately visible from the outside.

This provides a significant advantage for maintenance programs.

However, this does not mean that every inspection can be carried out without affecting the coating. The ability to perform non-destructive testing (NDT) through a coating depends on the specific inspection technique, material, thickness, and plant procedures. API RP 583 itself pays close attention to the capabilities and limitations of various non-destructive examination methods.

For this reason, inspection accessibility must be addressed during the design phase, not just when maintenance is due.

For storage tanks, this is especially beneficial on large surface areas or structural details that are difficult to insulate with rigid systems.

Download Savenergy.it Product Technical Datasheets

Research on thermal-insulating coatings has investigated the use of hollow microspheres as functional fillers for reducing heat transfer on industrial equipment and piping, while also considering the corrosion performance of the coating system.

Does an Insulating Coating Eliminate CUI Risk?

Yes, an insulating coating such as AES Tech or Technological M significantly reduces CUI risk.

The key benefit of a coating bonded directly to the substrate is that it eliminates the conditions typical of conventional systems, where moisture can penetrate and remain trapped underneath the insulation layer.

However, proper engineering design must still account for the substrate material, surface condition, operating temperatures, ambient environment, and planned maintenance procedures.

How to Choose Thermal Insulation for an Industrial Tank

Before selecting a solution, it is essential to determine fluid temperature, operating thermal range, ambient temperature and humidity, solar exposure, tank material, surface condition, existing corrosion issues, and the thermal target of the project.

Based on this data, the most appropriate coating cycle can be specified and verified for the specific application.

This step converts insulation from a simple outer coating into an integrated component of the plant’s thermal efficiency, protection, and maintenance strategy.

Thermal insulation of Industrial Tanks – FAQs

Why thermally insulate an industrial tank?

Insulation reduces heat exchange between the stored product and the environment, helping stabilize operating temperatures and control surface temperatures.

Can insulation help control condensation?

A properly sized system modifies surface temperature and helps manage conditions that lead to condensation. However, verification must consider temperature, relative humidity, and dew point under actual operating conditions.

What is Corrosion Under Insulation (CUI)?

CUI is a corrosive phenomenon that develops on metal surfaces hidden beneath an insulation system, typically in the presence of trapped moisture. It is a major issue in the petrochemical, chemical, and process industries.

How thick should nanotechnological tank insulation be?

It depends on the specific product and project requirements. AES Tech is applied at 1–5 mm, while Technological M ranges from 0.6–2 mm. Required thickness must be calculated for each specific case.

Does a thin-film coating facilitate inspections?

While traditional multilayer systems with removable external jacketing make inspections difficult, thin-film coatings significantly improve accessibility.

A Customized Solution for Every Project

Selecting industrial tank insulation should not be based solely on heat loss reduction.

Heat loss, condensation, CUI risk, tank geometry, and future inspection accessibility must all be evaluated together.

Savenergy.it offers ultra-thin industrial nanotechnological insulation suitable for tanks, silos, piping, and metal equipment.

Industrial Furnaces Insulation: Reducing Heat Loss and Radiant Heat from the Outside

Industrial Furnaces Insulation: Reducing Heat Loss and Radiant Heat from the Outside

Summary: Industrial furnaces insulation does not always require intervention on the internal refractory lining. When the external metal casing of a furnace reaches high temperatures and releases heat into the production area, an external thermal insulation treatment may be worth evaluating. AES Tech is an ultra-thin nanotechnology-based insulating coating that can be applied by spray in thicknesses of 1–4 mm. By measuring the actual temperature of the furnace casing before treatment, it is possible to assess whether external insulation can help reduce heat transfer, surface temperature and radiant heat without modifying the internal refractory system.

  • FAQ

Where Does an Industrial Furnace Lose Heat?

When industrial furnace efficiency is analysed, attention often focuses on burners, exhaust gases, heat recovery systems and process control.

However, heat can also be lost through the external furnace envelope.

Walls, doors, covers, ducts, joints and other external surfaces can transfer thermal energy to the surrounding environment through convection and radiation.

This means that a furnace can be operating correctly from a process point of view while still releasing a significant amount of heat through its external casing.

Large hot surfaces can contribute to the thermal load inside the production area even when their temperature appears relatively moderate compared with the internal process temperature.

This is one of the reasons why industrial furnace insulation should be assessed by looking not only at the internal temperature, but also at the actual temperature of the external surfaces.

Radiant Heat from Industrial Furnaces

Anyone standing close to a hot industrial furnace can often perceive heat without touching the equipment.

This is mainly due to radiant heat emitted by the external surface.

In facilities where several furnaces, drying ovens or other hot machines operate simultaneously, heat released by the equipment can contribute to:

  • higher temperatures in the surrounding working areas;
  • less favourable conditions for operators;
  • more demanding maintenance activities;
  • increased ventilation or cooling requirements;
  • unnecessary energy transfer from the process to the building.

When technically possible, reducing the external surface temperature means acting directly on the source of radiant heat.

Instead of managing the heat after it has entered the working environment, the objective is to reduce the amount of heat transferred through the furnace envelope.

Industrial Furnaces Insulation from the Outaside

Many industrial furnaces already contain refractory materials and internal insulation specifically designed for their operating conditions.

For this reason, external insulation should not be considered an automatic replacement for the original refractory or thermal design.

However, improving an existing furnace from the inside may require:

  • stopping the equipment;
  • removing components;
  • dismantling part of the refractory system;
  • rebuilding the internal layers after the intervention.

In certain situations, it can therefore be useful to consider a different approach:

applying thermal insulation directly to the accessible external metal casing.&amp;amp;lt;/strong>&lt;/p>

External insu

lation for industrial furnaces can be particularly interesting when the internal refractory system should not be modified or when conventional external insulation systems would create excessive thickness.

AES Tech: Industrial Thermal Insulation in 1–4 mm

<p>AES Tech is a nanotechnology-based thermal insulation coating developed for industrial applications.

It is applied in indicative thicknesses of 1 to 4 mm and is primarily installed using an Airless spray system.

Technician spray applying thermal insulation coating AES TECH to an industrial furnace

Spray application of AES Tech on the external metal casing of an industrial furnace, creating an ultra-thin continuous thermal insulation layer.

Roller or brush application can also be considered for small or difficult-to-access areas.

The extremely low thickness can be particularly useful on industrial equipment where conventional insulation panels, blankets or jackets may:

  • require additional space;
  • interfere with access;
  • be difficult to install around complex geometries;
  • require additional containment structures.

AES Tech follows the geometry of the substrate and can therefore be applied to metal surfaces, curves, joints, doors and irregular areas.

AES Tech is suitable for applications up to 240 °C.

However, the actual suitability of the system must always be evaluated according to the temperature of the surface to be treated and the real operating conditions.

Which Industrial Furnaces Can Be Evaluated for external insulation?

External thermal furnaces insulation can be considered for equipment with a hot, accessible metal casing.

Potential applications include:

  • drying ovens;
  • paint curing ovens;
  • industrial dryers;
  • hot chambers;
  • furnaces for resins and composites;
  • preheating equipment;
  • low- and medium-temperature process systems;
  • other industrial machinery with hot external surfaces.

The type of furnace alone, however, does not determine whether the intervention is suitable.

The most important parameter is often something much simpler: the actual temperature of the external metal surface during normal operation.

Internal Temperature Is Not Enough

To design a correct thermal furnaces insulation the internal temparature in not enough.

Two industrial furnaces operating at the same internal process temperature can have completely different external surface temperatures.

Why?

Because the temperature of the external casing depends on several factors:

  • furnace construction;
  • refractory stratigraphy;
  • condition of the existing insulation;
  • thermal bridges;
  • doors and joints;
  • equipment geometry;
  • operating cycle.

For this reason, knowing only that a furnace operates, for example, at a certain internal temperature is not sufficient to design an external furnaces insulation intervention.

The surface temperature of the casing must be measured directly.

This is one of the most important preliminary steps in evaluating industrial furnace insulation.

Before Insulating a Furnace: Measure the Surface Temperature

Technician measuring the external surface temperature of an industrial furnace with an infrared thermometer, a very important activity when ypu have to design the thermal insulation of furnaces.

Measuring the external surface temperature is a key step in assessing heat loss and determining whether industrial furnace insulation should be applied.

A technically sound assessment should begin with an inspection and a few essential measurements.

The most useful information includes:

  • internal process temperature;
  • external surface temperature;
  • ambient temperature;
  • dimensions of the hot surfaces;
  • annual operating hours;
  • substrate material and condition;
  • presence of particularly hot areas;
  • space and accessibility constraints.

Infrared temperature measurements can provide an initial indication of surface conditions.

Thermal imaging can also be useful for identifying areas such as:

  • doors;
  • joints;
  • edges;
  • panels;
  • connections;
  • thermal bridges.

These areas may operate at temperatures higher than the surrounding casing.

The objective is to establish a measurable situation before the treatment of thermal furnaces insualtion, so that any change in surface temperature can also be verified afterwards.

Why External Application Can Simplify the Intervention

Accessibility is an important consideration for maintenance managers.

A thin coating applied directly to the metal casing follows the shape of the equipment without requiring the volume associated with many conventional insulation systems.

This can be useful around:

  • doors;
  • curves;
  • fittings;
  • joints;
  • narrow passages;
  • irregular surfaces.

When the specific operating conditions permit it, an external treatment can also avoid modifications to the internal refractory system.

This does not automatically mean that the furnace can always remain in operation during application.

Surface preparation, application temperature, site safety and the condition of the equipment must be assessed for each project.

Real Case: Surface Temperature Reduced from 80 °C to 31 °C

A real AES Tech application provides a useful example of why surface temperature measurements are essential.

In a heating plant, AES Tech was applied to industrial pipework at a thickness of approximately 3 mm.

 

Industrial pipes insulated with AES Tech in a heating plant

Industrial pipework treated with approximately 3 mm of AES Tech in a real application where the measured surface temperature decreased from about 80°C to about 31°C.

The measured surface temperature was:

Before application: approximately 80 °C

After application: approximately 31 °C

 

This result refers to a specific application on industrial pipework.

It should not be interpreted as a performance guarantee for an industrial furnace.

The final temperature obtained after treatment depends on several variables, including:

  • initial surface temperature;
  • substrate material;
  • geometry;
  • applied thickness;
  • ambient conditions;
  • operating conditions.

The case study nevertheless demonstrates an important methodological point.

When evaluating industrial furnace insulation, performance should be assessed using the real temperatures of the equipment before and after the intervention rather than relying only on generic theoretical assumptions.

Savenergy.it Pre-Assessment Protocol

What Information Do We Need to Evaluate an Industrial Furnaces insulation?

Before proposing an AES Tech intervention, Savenergy.it analyses the real operating conditions of the equipment.

The preliminary information normally includes:

  • internal process temperature;
  • external casing temperature during normal operation
  • ambient temperature;
  • substrate material;
  • condition of the external surface;
  • approximate dimensions of the hot areas;
  • operating hours;
  • doors, joints, edges or other hotter areas;
  • space restrictions;
  • accessibility constraints;
  • photographs of the equipment.

The internal furnace temperature alone is not sufficient.

Two furnaces operating under similar process conditions can have very different external surface temperatures and may therefore require different technical evaluations.

Industrial Furnaces Insulation Should Start from Real Data

The objective is not simply to “insulate a furnace”.

For a plant manager or maintenance engineer, the real questions are:

How much heat is being transferred through the external casing?

Which areas have the highest surface temperatures?

Can these temperatures be reduced without modifying the internal refractory lining?

Would a few millimetres of external insulation solve a space or accessibility problem?

These questions make the assessment much more useful than simply choosing an insulation material based on its nominal properties.

External insulation with AES Tech can be particularly interesting when:

    • the metal casing is hot;
    • the surface is accessible;
    • available space is limited;
    • conventional insulation systems are difficult to install;
    • modifying the internal refractory system would be invasive.

Every industrial furnace is nevertheless different.

A technical assessment of temperatures, geometry, substrate and operating conditions is therefore necessary before defining the intervention and the appropriate thickness.

FAQ – Industrial Furnace

s Insulation

What Is External Industrial Furnaces Insulation?

External industrial furnaces insulation consists of applying an insulating system to the accessible outer surface of the furnace rather than modifying its internal refractory layers.

With AES Tech, the treatment consists of an ultra-thin insulating coating applied directly to the external metal casing.

Is It Necessary to Remove the Internal Refractory Lining

Not necessarily.

If the intervention is designed for the external casing, its purpose is precisely to work from the outside without directly modifying the refractory lining.

The feasibility of this approach must nevertheless be verified for the specific furnace.

Can External Insulation Reduce Radiant Heat?

Reducing the temperature of the treated external surface can also reduce the radiant heat emitted by that surface.

The actual result depends on factors such as initial temperature, substrate, coating thickness, geometry and operating conditions.

For this reason, surface temperatures should be measured before and after treatment.

How Thick Is AES Tech?

AES Tech is used for industrial thermal insulation in thicknesses of approximately 1–4 mm, depending on the application and the thermal objective.

Can AES Tech Be Applied to an Existing Furnace?

Yes.

Existing industrial machinery and metal structures are among the applications that can be evaluated for AES Tech.

Before application, the condition of the substrate, surface temperature, required preparation and operating conditions must be checked.

What Is the Maximum Application Temperature for AES Tech?

AES Tech is suitable for applications up to 240 °C.

The relevant parameter when assessing an existing furnace is the temperature of the external surface to be treated, not simply the internal process temperature.

How Is AES Tech Applied?

AES Tech is primarily applied using an Airless spray system.

Spray application allows the coating to follow complex geometries, joints, curves and irregular metal surfaces while maintaining very low thickness.

Roller or brush application can also be used on limited areas when appropriate.

Can AES Tech Be Applied Without Stopping the Furnace?

This must be evaluated case by case.

The possibility of working while the equipment is operating depends on:

  • actual surface temperature;
  • required surface preparation;
  • application conditions;
  • accessibility;
  • site safety requirements.

External application can potentially reduce the need for invasive work on the internal refractory system, but operating conditions must always be technically assessed.

Dairy Industry Piping: Why a Low-Thickness Thermal Coating Can Make a Difference

Dairy Industry Piping: Why a Low-Thickness Thermal Coating Can Make a Difference

Summary: in the dairy industry, the thermal management of piping affects process efficiency, condensation control, and operational continuity. A thermal coating for dairy piping can be an interesting solution when low thickness, fast application, and adaptability to complex lines, bends, valves, and metal surfaces are required. Savenergy.it products are nanotechnology-based thermal insulation solutions for industrial applications, specifically designed for interventions on piping, tanks, containers, cold rooms, and other technical surfaces.

Summary Index

  • Heat loss, condensation, and limited space
  • The advantage of low thickness
  • Where a thermal coating can be useful
  • FAQ

Why piping is a critical point in dairy plants

Industrial stainless steel pipes and valves in a dairy facility with Thermal Coating for Dairy Piping applications.

Industrial stainless steel pipes and valves in a dairy facility with Thermal Coating for Dairy Piping applications.

In the dairy sector, piping is not just a connection element between machines and tanks. It carries milk, hot water, chilled water, service fluids, and cleaning solutions, directly contributing to the stability of the production process. For this reason, insulating the lines can become a significant technical issue.

In this context, a thermal coating for dairy piping makes it possible to intervene on metal surfaces that often operate in environments where temperature, humidity, and frequent washdowns put materials under severe stress. Savenergy.it products are low-thickness nanotechnology-based thermal insulating coatings designed for industrial applications on piping, metal equipment, tanks, and cold rooms.

Heat loss, condensation, and limited space often make a thermal coating for dairy piping necessary

In dairy processing lines, heat loss can increase energy consumption and make it more difficult to maintain the desired operating conditions. Another important aspect is surface condensation, which in many production environments represents a critical issue that must be carefully monitored.

This is where the issue of thermal coating for dairy piping comes into play. When piping runs through technical areas, narrow passages, or zones with bends, flanges, supports, and valves, traditional high-thickness insulation systems are not always the most practical solution. Savenergy.it products are specifically designed to provide industrial thermal insulation with reduced thickness, anti-condensation performance, and airless spray application, a feature that is especially useful when plant geometry is complex.

The advantage of low thickness for a thermal coating applicable to dairy piping

In a dairy plant, the challenge is not only to insulate, but to insulate without making the system more complicated. Where there are closely spaced lines, valves, fittings, and sections that are difficult to cover, bulkier systems may become less practical.

Here, low thickness represents a real operational advantage. AES TECH is a semi-liquid nanocomposite solution for industry, applicable directly onto metal after substrate preparation, with installation recommended in multiple coats by airless spray. Its limited thickness, from 1 to 4 mm, makes it possible to consider the intervention even where line geometry makes traditional insulation more difficult.

Manti Ceramic Technological M follows the same application logic, with an indicative thickness of 0.6–2.0 mm, making it an interesting option when thermal protection and reduced bulk are required on metal and technical surfaces.

Which technical data are really relevant for a thermal coating for dairy piping

When evaluating a solution for insulating piping in the dairy industry, some data are more useful than others.

For AES TECH:

  • application thickness: 1.0–4.0 mm
  • fire reaction: Euroclass A
  • VOC content: < 0.003 μg/l (UNI EN ISO 16000-9:2024, 160000-6:2021, 16000-3:2022)
  • industrial application also on piping, containers, silos, metal equipment, tanks, and cold rooms

These data are important because they help show that the product fits into a different logic compared to traditional high-thickness insulation materials. The conductivity of 0.001 W/mK highlights the possibility of working with very limited thicknesses on metal substrates and industrial systems.

Industrial piping in a food environment, with some lines treated with AES TECH, a low-thickness solution also suitable for bends, valves, and fittings.

Industrial piping in a food environment, with some lines treated with AES TECH, a low-thickness solution also suitable for bends, valves, and fittings.

Where a thermal coating can be useful

In the dairy industry, a system of this type may be considered for:

  • metal process piping;
  • hot/cold service lines;
  • sections with bends, joints, and valves;
  • technical surfaces where low thickness is a priority;
  • plants where the bulk of the insulation must be kept to a minimum.

Savenergy.it products are water-based thermal protective coatings, formulated for industrial applications and characterized by good adhesion on various surfaces.

A technical choice to be evaluated case by case

In dairy plants, there is no single solution suitable for every line. Operating temperatures, washdowns, production cycles, the existing substrate, and accessibility all influence the choice. For this reason, it is useful to evaluate materials and layer build-up according to the actual system.

Savenergy.it products are designed to meet specific industrial needs, especially when thermal insulation, condensation elimination, fast installation, and reduction of overall thickness are required. In a demanding sector, a thermal coating for dairy piping can therefore represent an interesting technical solution for improving line management without burdening the system with excessive bulk.

FAQ

Is a low-thickness thermal coating suitable for dairy plant piping?

It is a solution worth considering when reduced bulk, application on complex surfaces, and coating continuity on metal elements are required.

Why is low thickness important in the dairy industry?

Because in many industrial lines, space is limited and bends, valves, fittings, and supports must remain accessible.

How are Savenergy.it products applied?

For products in the industrial line, the application method consists of multiple coats using an airless sprayer, following the installation manual.

Are AES TECH and Technological M also suitable for other industrial applications?

Yes, also for containers, silos, metal equipment, tanks, and cold rooms.

Industrial warehouse interior with high shelving and stored goods, example of insulation for industrial buildings

Why insulation for industrial buildings matters today

When we talk about insulation for industrial buildings, the discussion often focuses only on energy saving. In reality, the topic is much broader. In industrial, logistics and agricultural environments, an inefficient envelope can create overheating, cold internal surfaces, condensation and unstable indoor conditions.

This directly affects:

  • worker comfort
  • the preservation of goods and packaging
  • the durability of metal surfaces
  • the efficiency of storage and production areas
  • the continuity of operations

In industrial sheds, warehouses, hangars, livestock buildings and agricultural facilities, roofs and walls are continuously exposed to solar radiation, cold, humidity and sudden weather changes. That is why choosing the right solution for insulation for industrial buildings is not just a technical detail, but a practical decision that can affect the daily use of the building.

The most common problems in industrial roofs and walls

1. Overheating in summer

Metal roofs can absorb a high amount of solar radiation and transfer heat indoors. This can increase discomfort and put additional stress on cooling systems.

2. Cold surfaces and condensation

In winter or during seasonal transitions, poorly insulated walls and roofs can cool down quickly. This may create surface condensation, especially where indoor and outdoor temperatures differ significantly.

3. Damage to goods and technical components

Condensation and thermal fluctuations can affect:

  • paper and cardboard packaging
  • raw materials and semi-finished products
  • sensitive equipment
  • metal elements exposed to corrosion risks

4. Difficult interventions on existing buildings

Many industrial buildings require fast and low-impact solutions, especially when production or storage activities cannot stop for long.

Our approach to insulation for industrial buildings

At Savenergy, we work with nanotechnological thermal insulation systems designed for industrial applications where low thickness, versatility and practical installation are essential.

AES TECH and Technological M: quick comparison

AES TECH

  • Thickness: 1–4 mm
  • Focus: metal and technical surfaces
  • Best for: walls, tanks, pipes, cold rooms, industrial elements
  • Key advantage: greater applicable thickness where higher insulation contribution is needed

Technological M

  • Thickness: 0.6–2 mm
  • Focus: roofs and outer surfaces
  • Best for: industrial sheds, agricultural buildings, external coverings
  • Key advantage: thermal protection plus waterproofing on exposed surfaces

Main application scenarios of the Insulation for industrial buildings

1. Industrial sheds with sun-exposed metal roofing

This is one of the most common cases. During summer, sheet-metal roofs can become a major source of indoor heat. In these situations, Technological M is particularly valuable because it works directly on the roof and also adds waterproofing protection.

2. Storage warehouses with sensitive goods

In warehouses, the issue is not only people’s comfort. Thermal peaks and condensation can damage packaging, components, raw materials and stored products. Here, insulation for industrial buildings becomes an operational necessity as well as a technical one.

3. Hangars and large-volume structures

In hangars or lightweight industrial buildings, very large internal volumes make indoor climate control more complex. If the roof overheats in summer or cools too quickly in winter, discomfort increases and HVAC systems work harder.

4. Livestock and agricultural buildings

In these environments, microclimate control is essential. Roof overheating may increase heat stress, while condensation can worsen indoor hygiene and environmental conditions. Technological M can be especially useful on roofs, while AES TECH can be considered for other critical metal elements.

5. Metal walls affected by condensation

When the main issue is a cold inner wall, AES TECH is often one of the most interesting options because it is particularly suitable for industrial metal surfaces and technical applications.

6. Mixed-substrate buildings

Not all industrial structures are uniform. Many include metal, wood, PVC or plastic components. In these cases, using low-thickness systems that adapt to different surfaces can be a major practical advantage.

7. Buildings that require fast, low-impact work

Where production cannot stop for long, airless spray application and reduced thickness can make the intervention more manageable and less invasive than traditional high-thickness systems.

A key advantage: low thickness and practical flexibility for the Insulation for industrial buildings

One of the most interesting aspects of our solutions is the balance between insulation performance and limited thickness.

This can be particularly useful when:

  • the structure should not be overloaded
  • internal volume must be preserved
  • the building is already in use
  • traditional insulation would be too invasive
  • the intervention must adapt to complex surfaces

For industrial projects, low thickness is not only a technical value. It is often a practical advantage that can simplify the whole intervention.

How we choose between AES TECH and Technological M for the Insulation for industrial buildings

In general, we tend to highlight:

  • Technological M when the main issue concerns the roof, the external envelope or waterproofing needs
  • AES TECH when the intervention focuses on metal walls, technical surfaces, industrial equipment or areas where a greater thickness is needed

In many cases, the right approach is not to think in abstract terms about one product only, but to assess:

  • the type of roof
  • the type of wall
  • the substrate
  • the intended use of the building
  • the main thermal and condensation-related critical points

Conclusions

Insulation for industrial buildings is no longer just a matter of reducing energy consumption. It is a decision that affects comfort, condensation control, protection of goods, surface durability and the day-to-day functionality of industrial and logistics spaces.

Industrial sheds, warehouses, hangars, depots and agricultural buildings all have different needs, but one principle remains the same: roofs and walls must be treated with solutions that fit the real materials, the real loads and the real critical issues of the building.

With AES TECH and Technological M, we can address these needs through a low-thickness, flexible and technically focused approach.

Thermal Bridges: How to Eliminate Them with Manti Ceramic in Internal and External Insulation

Thermal Bridges: How to Eliminate Them with Manti Ceramic in Internal and External Insulation

Summary: Thermal bridges are one of the main causes of energy loss in buildings. These discontinuities in the building envelope create cold surfaces, condensation, and mold, compromising indoor comfort and health. Eliminating thermal bridges is therefore essential to improve building energy efficiency. Today, thanks to nanotechnology applied to construction, it is possible to intervene with innovative systems such as the Manti Ceramic micro-coating, which allows thermal bridges to be corrected from both the interior and exterior with minimal thickness.

  • FAQ

What Are Thermal Bridges?

Thermal bridges are areas of the building envelope where heat flow is greater than in the surrounding surfaces.

This phenomenon occurs when wall insulation is not continuous or when structural elements with higher thermal conductivity interrupt the insulation layer.

Critical insulation points are commonly found at:

  • reinforced concrete beams and columns
  • balconies and floor slabs
  • window reveals
  • wall-to-roof junctions
  • structural joints

In many existing buildings, these critical insulation points are among the main causes of energy loss and mold formation.

Examples of thermal bridges in buildings such as windows, balconies and wall junctions, and application of Manti Ceramic on a window reveal to reduce heat loss.

Why Thermal Bridges Cause Energy Loss

The presence of thermal bridges leads to several technical and economic problems.

Areas affected by thermal bridges disperse more heat than the rest of the wall.

Surface Condensation

Interior surfaces become colder, promoting water vapor condensation.

Mold Growth

Persistent humidity creates ideal conditions for mold development.

Example of thermal bridges detected with thermography that create cold surfaces and cause mold formation on interior walls.

Heating systems must compensate for thermal losses, increasing energy consumption.

For this reason, modern building design increasingly focuses on reducing or eliminating thermal bridges.

The Limits of Traditional Insulation Systems in Reducing Thermal Bridges

Traditional external insulation systems are widely used to improve building energy efficiency. However, they present several limitations when addressing thermal bridges:

      • highthickness (8–16 cm)
      • difficulty of application in construction junctions
      • invasive interventions on façades
      • difficulties with internal insulation due to thickness

Moreover, elements such as balconies, columns, and window reveals are often impossible to insulate effectively with traditional panels.

For these reasons, many professionals are looking for more flexible solutions to correct thermal bridges.

Thermal Bridges and Nanotechnology

In recent years, material innovation has led to the development of nanotechnology-based insulation materialswith thermo-reflective properties.

These materials do not work only by increasing thermal resistance but also by blocking part of the thermal wave.

In the case of Manti Ceramic, the structure contains vacuum ceramic microspheres that help reduce heat transfer and improve insulation efficiency.

This technology allows critical insulation points to be treated with much smaller thicknesses compared to traditional systems.

Why Manti Ceramic Is Ideal for Correcting Critical Insulation Points

Practical Applications: Internal and External Insulation

One of the main advantages of Manti Ceramic is its application flexibility.

External Insulation

The product can be applied as an alternative or complement to traditional external insulation to correct critical façade insulation points.

Internal Insulation

In many condominium buildings or historic properties, interventions on external façades are not possible. In these cases, internal insulation becomes an effective solution.

Thanks to its minimal thickness, Manti Ceramic can reduce thermal bridging without compromising living space.

Technical Insight

From a building physics perspective, critical insulation points represent a local variation in the thermal resistance of the building envelope.

The thermal transmittance of a wall is calculated with the formula:

U = 1 / Rt

where Rt represents the total thermal resistance of the wall assembly.

When materials with high thermal conductivity (such as reinforced concrete) interrupt the insulation layer, heat flow increases and a thermal bridge is created.

Advantages of Correcting Thermal Bridges

  • reduction of energy losses
  • improved indoor comfort
  • prevention of mold formation
  • longer durability of walls and structures
  • improvement of the building energy class

Glossary

  1. Thermal bridge
    An area of the building envelope where heat flow is higher.
  2. Thermal transmittance
    The amount of heat passing through a surface.
  3. Thermal reflectance
    The ability of a material to reflect thermal energy.
  4. Thermal phase shift
    he time required for heat to pass through a building structure.
