Cleartherm™ is a completely new rooflight insulation system developed to meet the tighter requirements of the revised Building Regulation and is providing a range of thermal layer options for both site and factory assembled Trilite rooflights.

- Cleartherm™ has a Trilite GRP weather sheet, a structured polycarbonate middle layer and a Trilite GRP base sheet.

- Cleartherm™ allows rooflight constructions to achieve a range of U values from 2.0 - 1.0m²K by incorporating differing structural configurations within the units.

- Using Cleartherm™ gives minimal reduction in light transmission due to the 'glass clear' clarity of the polycarbonate used.

- Its use ensures better thermal performance over standard triple skin rooflights due to Cleartherm™'s own inherently higher U value.

- Cleartherm™ used as part of any Trilite site or factory assembled multi-skin construction will achieve the following thermal performance:

- Are easily installed into traditional double skin site assembled rooflight constructions by lying directly on top of the liner profile without fixings.

- Eliminate the need for additional spacer systems or fillers due to Cleartherm™'s own internal structure creating the insulating air gap.

- Come in sheets sizes up to 6m, pre-cut to customers requirements.

- Are delivered palletised for protection and ease of on-site handling.

- Provide greater inherent U value, giving a margin of error for as built installation details, so increasing the likelihood of actual thermal performance.
