Gorter is excited to share their ground breaking news that once again they have increased the insulation rating of our roof hatches. Thanks to an innovative modification to the patented design, the insulation rating of the roof hatch now comes in at Uw ≤ 0,319 W/(m².K)

New Gorter RHT roof hatch


A high insulation rating of Uw ≤ 0,319 W/(m².K) is unheard for roof hatches. It is yet again an outstanding achievement that Gorter has not only had the insulation rating confirmed according to EN-ISO 10077-2, but that this tested rating again applies to the whole structure.


There has been for some time now, other roof hatches on the market, with the rating of their insulation material expressed as if it was the rating for the whole roof hatch. This is certainly not true! The ultimate insulating effect is determined by the weakest link and that is always the thermal bridge in the structure caused by the aluminium or steel used. That is why the whole structure of the new version of the Gorter roof hatch is again fully thermally broken.


Energy-Efficient Roof Hatch Prevents Condensation

The new Gorter roof hatch now delivers not only energy efficient benefits, but prevents the unwanted condensation that collects on the inside of the cover. If you’re looking for a roof hatch that helps achieve a higher classification on the energy label, the new Gorter roof hatch is the right hatch of choice.


RHT++ Roof Hatch for Maximum Safety

The new roof hatches, as is with all Gorter hatches and combinations, are safety tested to the most stringent EN standards and are supplied with a TÜV NORD certificate, Aboma safety mark and KOMO® certificate. The new roof hatch is also fitted with a hand rail in a yellow finish which is characteristic to Gorter, and provides a secure grip when accessing or exiting the roof. All Gorter roof hatches can be operated with one hand so you will always have a hand free for balance and support.
