Metal roof buildings are widely used for industrial sheds, warehouses, factories, commercial buildings, poultry farms and agricultural structures due to their durability and cost-effectiveness. However, one major challenge associated with metal roofing is excessive heat gain during summer and heat loss during winter. Without proper insulation, metal roofs can create uncomfortable indoor conditions, increase energy consumption and reduce operational efficiency.

This is where Under Deck Insulation becomes an essential solution. Installed beneath the metal roof, under deck insulation acts as a thermal barrier that helps control temperature, improve energy efficiency, and enhance occupant comfort. Neo Thermal Insulation offers advanced reflective aluminium foil insulation solutions specifically designed for metal roof buildings, providing superior thermal performance and long-term benefits.

What is Under Deck Insulation?

Under Deck Insulation is a thermal insulation system installed directly underneath a metal roof deck. It creates a protective layer that minimizes heat transfer between the roof and the interior space.

Typically, under deck insulation consists of reflective aluminium foil combined with air bubble insulation technology. This structure reflects radiant heat away from the building while reducing conductive heat transfer.

By installing Under Deck Insulation, building owners can significantly improve indoor comfort and reduce cooling costs throughout the year.

Why Metal Roof Buildings Need Under Deck Insulation

Metal roofs absorb a large amount of solar radiation during the day. As the roof temperature rises, heat is transferred into the building, causing indoor temperatures to become uncomfortable.

Common problems caused by uninsulated metal roofs include:

Excessive indoor heat during summer

Increased air-conditioning costs

Temperature fluctuations

Condensation issues

Reduced worker productivity

Equipment overheating

Poor indoor comfort

Installing Under Deck Insulation helps eliminate these problems by reducing heat penetration through the roof structure.

INSUshield – a perfect duct lining material. Use of proper duct lining material is essential to achieve triple objectives of modern residential, commercial and industrial facilities, that is, saving on energy consumption, occupant comfort and safety. It should be noted that properly insulated HVAC duct systems is necessary to ensure a healthier, more productive and more attractive environment within a building. An efficient duct lining material is one which is able to keep interior ducts free of foreign materials that bring fibres into the air stream and absorb moisture.

One need to be careful while selecting the duct lining material and ensure that it has closed-cell structure. A closed-cell structure is essential to prevent moisture vapour intrusion. Moisture is the single most reason for insulation failure. The duct insulation material should also be able to maintain indoor air quality by resisting condensation and moisture intrusion and ensure that the air passing over it does not contain fibres or dust. The duct lining material should also be able to achieve noise reduction through the absorption of air-borne and structure borne sound waves and the subsequent conversion of sound energy into heat.

Supreme Industries offers a range duct lining materials like INSUshield that provide superior thermal and acoustical performance and are manufactured with advanced technologies.

INSUshield is the most suitable product for duct lining as it is a non-fibrous, fire retardant (FR), closed-cell, tri-dimensional chemically crosslinked polyethylene foam. It is a better alternative to conventional Glass Wool insulation material. Since it is more than 90% closed-cell, there will be negligible water and moisture absorption. It is also certified ‘Class O’ in Fire Propagation and ‘Class 1’ in Surface Spread of Flame as per BS 476 Part 6 & Part 7, respectively. Above all, it is an environment and user friendly material.

INSUshield provides good thermal insulation due to its low and stable ‘K’ value. It is non-toxic and non-carcinogenic. Further, it has wide operating temperature range from -40°C to + 115°C.

Thus, INSUshield is a product which help you to create more comfortable and energy efficient indoor environment when lining ducts inside HVAC systems.

Insulation of split AC tubing is important to avoid condensation leaks into the building. Insulation of split AC tubing is essential as the refrigerant inside the tubing is at very low temperature and length of piping between and outdoor unit and indoor unit is quite long. Further, the tubing is exposed to the open atmosphere which is at very high temperature. If this is left without insulation all the cooling effect will be lost to the open atmosphere and by the time the refrigerant enters the cooling coil its temperature will already be too high and the purpose of producing the cooling effect will not be served. To avoid this, the refrigerant tubing connecting the indoor and the outdoor unit is covered with the insulation.

If split AC tubing is not properly insulated, there can be costly building damage where condensate drips wet gypsum board walls, leading to a costly mold remediation project. Also, improper insulation of split AC tubing may increase system operating cost or in addition to a condensation worry, uninsulated high pressure refrigerant lines may result in unwanted heat transmission into some building areas.

There are many insulation material for split AC tubing is available in the market but INSUflex manufactured by Supreme Industries has a proven track record of performance and efficiency.

INSUflex (NBR tubing) is a fire retardant closed-cell flexible elastomeric pre-formed tubing thermal insulation product that is extensively used for insulation of split AC tubing. It provides a high water vapour transmission resistance factor which ensures a low stable thermal conductivity, thereby saving energy and ensuring efficiency of the system, wherever applied. Its low thermal conductivity also ensures trouble free performance.

It is light weight and flexible tubing is available in various pipe sizes and thickness combinations for diverse applications.

INSUtapes are very effective adhesive coated joint sealing tapes. Adhesive coated joint sealing tapes play an important role in enhancing the effectiveness of insulation and waterproofing as they prevent the passage of moisture and water through joints and cracks. For this purpose, adhesive coated joint sealing tapes should be tear resistant and have good and strong adhesive.

Adhesive coated joint sealing tapes selected for the job should have the strength to withstand pressure and variation in climate. The quality of the tape is also to a great extent dependent upon the quality of adhesive used. Acrylic based adhesives are always preferred because of their high tack and high shear strength. Also acrylic adhesive functions normally at high or low temperatures. It has high-bonding strength on various surfaces. For example, INSUtapes manufactured by Supreme Industries is often recommended for insulation joint sealing because of its strong and aggressive adhesiveness.

Available in various widths, INSUtapes are fire-retardant, non-fiberous, tri-dimensional chemically crosslinked PE foam tapes – plain / laminated with aluminium foil on one side and other side coated with special acrylic adhesive. INSUtapes, available in different thickness, is a single coated tape that can be used for a wide variety of difficult sealing applications. The backing on this tape is very tough yet flexible and abrasion resistant. It’s very soft and thick acrylic adhesive has excellent sealing properties and good outdoor durability.

It is protected from UV radiation by an aluminium foil which makes it possible to use the tape outdoors. The self-adhesive surface provides for perfect quality adhesion to many different surfaces: metal, slate, wood, plastic, plaster, concrete, glass, etc. It provides strong adhesion at joints even on angular surfaces. Further, it is supplied with stiff release paper for ease of removal, thus saving application time. The application technique of INSUtapes is extremely simple and does not require sophisticated tools or skilled manpower.

Apart from sealing the longitudinal, transverse joints and corners in ducts, under roofs, pipes, floor and wall insulation, INSUtapes are also widely used for joint sealing on the PEB roof tops where conventional sealants barely provide a long term sealing solution.
