Application

The Gorter RHT standard roof hatch is suitable for installation on flat roofs with a maximum slope of 30° and can be used in a wide range of buildings, including offices, factories, apartment buildings, villas, shopping malls, hotels and public-sector facilities. It provides a safe and compliant solution for roof access and emergency escape, enabling routine maintenance, inspections, servicing of rooftop installations, roof terrace access and emergency egress.

Typical applications include:

Rooftop access for HVAC systems, window cleaning installations and roof inspections
Access to roof terraces, green roofs and amenity spaces
Inspection and maintenance access for solar panel installations
Access to telecommunications equipment and antenna installations

The RHT roof hatch is also available in bespoke sizes with a single lid or double lid. For projects with specific requirements or demanding environments, Gorter also offers roof hatches with extreme insulation values, glazed roof hatches and fire-rated roof hatches.

The Gorter RHT roof hatch has been installed in a wide variety of projects worldwide, ranging from the Burj Khalifa to the Heydar Aliyev Centre. Click here for more reference projects.

Description

The new generation RHT roof hatches feature an extremely strong and patented construction. Thanks to several modifications, the roof hatch is even more resistant against unexpected extreme loads, both during construction and in general use.

Proven insulation performance of the complete roof hatch

With the RHT roof hatch, the insulation value is calculated for the entire construction (Uw), not just the insulation material. This sets Gorter apart in the roof hatch market, where many suppliers only provide the PIR insulation value. The proven insulation performance of the complete hatch is Uw ≤ 0.276 W/(m²·K).
