The Sancell Therm 4.0 + Lap Foil Insulation is a high-performance reflective insulation and vapour barrier designed to enhance thermal efficiency in residential and commercial building envelopes. It helps control radiant heat transfer, improving indoor comfort by reducing heat gain in hot conditions and heat loss in cooler environments.
Dimensions: 1350mm (Width) x 22.25m (Length)
Coverage: 30m² Total
Application: Roof, wall, and ceiling reflective insulation / radiant barrier
Material: Multi-layer reflective foil laminate with integrated lap system
Thermal Performance: Provides high thermal resistance through radiant heat reflection, helping improve overall building envelope performance and reduce temperature extremes inside the building.
Moisture Control: Functions as a vapour barrier, helping reduce condensation risk in roof and wall systems when installed correctly.
Installation: Supplied in roll format with built-in lap for easier overlapping and sealing. Designed for use in roofing, wall, and ceiling applications, typically installed with approved fixing systems and foil tape for optimal performance.
Energy Efficiency: Improves building energy efficiency by reducing reliance on mechanical heating and cooling systems, leading to lower energy consumption.
The Sancell Therm 4.0 + Lap is suitable for residential, commercial, and industrial buildings. It is commonly used under metal roofing, in wall systems, and ceiling applications where high radiant heat control and vapour management are required to improve overall thermal comfort and building performance.
