The Sancell Therm 4.0 + Lap Foil Insulation is a high-performance reflective insulation and vapour control membrane designed to improve thermal efficiency and indoor comfort in residential and commercial buildings. It works by reflecting radiant heat, helping to reduce heat gain in summer and heat loss in cooler conditions.
Dimensions: 1350mm (Width) x 33.4m (Length)
Coverage: 45m² Total
Application: Roof, wall, and ceiling reflective insulation / radiant barrier
Material: Multi-layer reflective foil laminate with integrated lap system
Thermal Performance: Provides strong radiant heat reflection performance, helping to reduce overall heat transfer through the building envelope and maintain more stable indoor temperatures.
Moisture Control: Acts as a vapour barrier, helping reduce condensation risks when correctly installed in roof and wall systems, supporting long-term building durability.
Installation: Supplied in roll form with a built-in lap for easier overlapping and sealing. Designed for installation in roofing, wall, and ceiling systems using appropriate fixings and foil tape to ensure maximum effectiveness.
Energy Efficiency: Enhances building energy performance by reducing dependence on heating and cooling systems, contributing to lower energy consumption and improved comfort.
The Sancell Therm 4.0 + Lap is suitable for residential, commercial, and industrial construction. It is commonly used under metal roofing, in wall cavities, and ceiling systems where high levels of radiant heat control and vapour management are required to improve thermal comfort and overall building efficiency.
