The Gorter aluminium roof hatch is the only one in the roof hatch category with a proven very high insulation value. EuroSolid investigated the thermal performance according to EN ISO 10077-2 and states officially that Gorter RHT roof hatches have an insulation value of: Uw ≤ 0,319 W/(m².K). These and other performance levels of the aluminium roof hatch are set out in a European Technical Assessment (ETA) document that provides indisputable evidence of proven performance and the affixed CE mark.


Structural benefits of aluminium roof hatches

Gorter aluminium roof hatches are up to three times lighter than comparable steel roof hatches. The adjustments needed to the roof structure are minimal due to very low stress on the roof. The lightweight RHT roof hatches are easy to lift and can be installed on the roof without much equipment.


Roof hatch saves on structural costs

When creating a roof access, a roof hatch offers a lot of advantages compared to a rooftop unit or garret. With a roof hatch there is always one floor less to build. This will save you money on construction and future energy costs. The appearance of the building will remain unaltered thanks to the low height of the roof hatch. Partly because of this, there is usually no need for a permit to install a roof hatch.


Safety of the roof hatch

All Gorter aluminium roof hatches and combinations are safety tested to the most stringent EN standards and are supplied with a CE and TÜV NORD certificate, Aboma safety mark and KOMO® certificate.
