Cleartherm2 is a specially engineered 10mm 4-wall polycarbonate sheet used as a super thermal intermediate skin in site assembled rooflights. It is used with Safelight, Trilite and Marlon CS Longlife weather and liner sheets, creating thermally efficient triple skin rooflights. When installed into site-assembled profiled rooflights, a U-value of 1.3W/m2K is achieved with U-values down to 0.9W/m2K available.
- Better thermal performance: U-value of 1.3W/m²K with options as low as 0.9W/m²K
- Offers 70% better insulation than current Part L Building Regulations requirements
- Easily installed into traditional double skin rooflight constructions to create a triple skin rooflight
- Glass clear clarity provides exceptional light transmission
- Eliminates the need for additional spacer systems or fillers
