Design details

Rooflight F100 Access Hatch technical design characteristics

Energy efficiency

The Rooflight F100 Access Hatch is the PVC framed square or rectangle shaped PETG domed rooflight, opening for ladder access, with maximum energy efficiency and thermal insulation. With high levels of wind and driving rain resistance, alongside enhanced isothermal characteristics in the overall construction – the unrivalled performance of this range results in no condensation alongside excellent air tightness values. The thermally broken “isothermally balanced” PVC frames feature optimally aligned 10° isotherm line. This means that the thermally broken 10° isothermal line remains within the structure (see diagram​​​​​​​) for consistent heat insulation without any weak spots, reducing condensation, mould and bacteria. The TIP (Total Insulated Product) is certified in accordance with EN ISO 14021.


•    CE marked quality according to EN 1873
•    Life Cycle Assessment (LCA) to EN 15804
•    Certified watertightness against heavy and driving rain: DRI 3.0 m²/s                     (reference size 1200 x 1200mm)
•    Wind Load to Class C4, EN 12210
•    ACR[M] Class B Non-fragile

Quality control of component manufacture: 

•    Energy management system to EN ISO 50001:2011
•    Quality management system to EN ISO 9001:2015
