The best roof hatch starts with Gorter®
At Gorter®, everything revolves around providing the right solution for every roof. Whether you choose increased daylight, extra insulation or fire safety, every Gorter roof hatch is engineered to the same high quality standard.
The roof hatches form a reliable part of the thermal envelope, allowing you to continue the roof’s insulation line without interruption. The construction is fully thermally broken and offers an excellent insulation value with a comfortable margin above the current BENG requirements. In practice, this prevents cold bridges and condensation.
As an architect, engineer or designer, you can download all product specifications, 3D BIM models (Revit/ArchiCAD) and STABU texts directly from our website.

Tips for choosing the right roof hatch
The best roof hatch starts with making the right choice: will it be used for maintenance access, as an escape route or as a daily passageway? Consider good insulation to retain warmth and comfort, and check whether fire resistance is required. A roof hatch that is easy to operate with gas springs or electric control makes the job easier, while durable materials such as aluminium ensure a long service life and minimal maintenance.
The right solution for every application
Gorter offers several roof hatch variants, tailored to specific needs:
Environment and sustainability
For architects, designers and building owners, sustainability is becoming increasingly important, which has led to our new SHI certification for the RHT roof hatch. With this quality mark, you choose proven quality and certainty regarding the emission properties of your building materials. This ensures that your project not only complies with current legislation, but also guarantees a healthy and safe end result that retains its value.
