Gorter aluminium roof hatches are up to three times lighter than comparable steel roof hatches. The necessary changes to the roof structure are minimal because of the limited stress on the roof. The lightweight RHT roof hatches are easy to lift and can be installed on the roof without much equipment.


When creating a roof access, a roof hatch offers a lot of advantages compared to a rooftop structure. Indeed, 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 no need for a permit to install a roof hatch.
