Design details

Glass Skylight FE Access Hatch technical design characteristics

Energy efficiency

The Glass Skylight FE Access Hatch is the aluminium framed square or rectangle shaped roof access hatch with maximum energy efficiency and thermal insulation. With high levels of wind and 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” aluminium 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 Glass Skylight FE Access Hatch also benefits from precision profiles incorporating Thermo Active Design which produces the smooth isothermal lines. 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
•    Airtight to Class 4, EN 12207
•    Water tightness to Class 4 according to BS EN 12208
•    Wind Load to Class C4, EN 12210
•    CWCT Class 2 Non-fragile

Quality control of component manufacture: 

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

Design detail

1 - Structural glazing design

2 - Smooth crossover between glazing and frame profile, ensuring rainwater can run-off easily without any dirty edges

3 - "Warm edge" (spacers between the panes, made of materials with low thermal conductivity), as a standard feature

4 - Integration of all drives and components in the profile frame

5 - TAD – Thermo Active Design: Kink-free isothermal curve in the profile system

6 - Thermally optimised insulation core

7 - Thermally insulated GRP upstand with seamless silk-white interior finish (RAL 9016)
