About Duct Insulation

Duct insulation is a barrier that slows down heat transfer through duct walls, helping to maintain the desired temperature of the air inside the duct. This helps HVAC systems work more efficiently, and can also improve a home's energy efficiency, air quality, and prevent condensation.

Here are some things to know about duct insulation:

How it works: Duct insulation works by trapping air bubbles or pockets of air among fibers, which are poor conductors of heat. Thicker insulation is generally more effective.

Types of insulation

Some types of duct insulation include:

Ductwrap: This insulation is often made of mineral wool or fiberglass, and is easy to install. It has a foil-facing that reflects heat and acts as a vapor barrier.
XLPE: This insulation comes in sheets and rolls, and can be installed using an adhesive.
Polyurethane: This foam insulation is moisture resistant and has a high operating temperature, but its fire resistance is low.
Rock wool: This insulation is made from melted rock spun into fibers, and is known for its fire and thermal resistance. However, it can be difficult to install due to its bulkiness and weight.
Fiberglass: This insulation is made from melted glass fibers, and is popular for HVAC systems due to its low cost and ease of installation. However, it can be itchy and difficult to handle.

Superior Moisture Resistance

Thanks to its closed-cell structure, our duct insulation provides excellent protection against water absorption, keeping systems dry and preventing internal condensation. With less than 0.20% water absorption by volume, it substantially reduces the risk of mold growth and corrosion within HVAC applications.

Exceptional Fire Safety

This duct insulation is rigorously tested to meet Class 0/Class 1 fire safety standards according to BS 476. Its fire-retardant nature makes it well-suited for commercial and industrial environments where fire performance is critical, offering peace of mind and compliance with stringent safety regulations.

Flexible Sizing and Easy Installation

Available in standard 1-meter widths and customized lengths or thicknesses (6 mm to 50 mm), this insulation can accommodate diverse ductwork shapes and sizes. Installation requires only adhesive tapes or glue, with a simple wrap-and-seal process to ensure no gaps, promoting both performance and efficiency.

FAQ's of Duct Insulation:

Q: How is this duct insulation installed for best performance?

A: For optimal results, ensure the duct surface is clean and dry before applying the insulation. Use adhesive tape or glue to secure the material, wrapping it tightly around ducts with no gaps or overlaps. For extra durability, you can choose an optional aluminum foil or UV-resistant facing, especially for outdoor or exposed areas.

Q: What are the main benefits of using this foam rubber duct insulation?

A: This insulation provides superior moisture resistance, high thermal efficiency, and excellent fire safety. Its closed-cell structure minimizes water absorption, while the Class 0/Class 1 fire rating ensures safety. It is lightweight, flexible, odourless, non-corrosive, resistant to fungi and bacteria, and easy to install in various HVAC applications.

Q: When should UV-resistant facing be used with duct insulation?

A: UV-resistant facing is recommended if the ducts are exposed to direct sunlight or outdoor conditions. This facing protects the insulation from UV degradation, ensuring a longer service life and maintaining its insulating properties over time.

Q: Where can this insulation be applied most effectively?

A: This duct insulation is ideal for HVAC ducts, air conditioning lines, refrigeration systems, and ventilation channels in commercial, residential, and industrial buildings throughout India. It can be used in both indoor and protected outdoor environments when paired with appropriate facing.

Q: What is the process for custom sizing or cutting the insulation material?

A: Insulation rolls and sheets can be custom-cut to match any duct configuration. Simply measure the required dimensions and use a sharp blade or scissor to achieve a precise fit. Multiple thickness options (6 mm to 50 mm) and customizable widths ensure compatibility with diverse project needs.

Q: Is this duct insulation safe to use with metal ducts regarding corrosion?

A: Yes, the insulation is non-corrosive to metal ducts. Its material composition prevents chemical reactions that can lead to corrosion, ensuring the longevity and integrity of the ductwork system.
