Brett Martin ClearTherm
ClearTherm is a lightweight multi-wall polycarbonate sheet used as an intermediate layer in in-plane rooflight systems to improve thermal performance.
It is used within site and factory assembled rooflights to form triple skin systems, combining with GRP weather and liner sheets to support improved insulation while maintaining high levels of natural light transmission.
- 10 mm 4-wall polycarbonate intermediate skin
- Used to form triple skin rooflight systems
- U-values down to 0.9 W/m²K
- High light transmission with clear polycarbonate
- Lightweight material for easier handling
- Eliminates need for spacer systems or fillers
ClearTherm is used within in-plane rooflight constructions to improve thermal efficiency while maintaining natural daylight levels.
The 4-wall polycarbonate structure acts as an intermediate insulating layer between GRP weather and liner sheets, forming a thermally enhanced triple skin system.
It is designed for use in both site and factory assembled rooflights where improved insulation performance is required without reducing light transmission.
