Processing

The Gorter roof hatch with window provides practical and safe access to flat roofs, rooftop terraces and gardens, with a maximum slope of 5°.

Glazed roof hatch for natural daylight in the room below

The RHTG glazed (window) roof hatch guarantees natural daylight in the room below. This can provide a solution for apartments with a roof terrace, homes with few windows, office buildings or other non-residential constructions.

Floor height

The Gorter combination of glazed roof hatch and GS50 fixed staircase offers a stylish and permanent solution for roof access with floor heights from 2,500 to 3,000 mm. The Gorter combination of roof hatch RHTG9024 and GS55 fixed staircase and roof hatch RHTG9030 and GS55 fixed staircase are suitable for floor heights from 3,000 to 3,370 mm.

Fully thermally broken

The Gorter RHTG roof hatch has a fully thermally broken curb and a cover with high-efficiency glass HR+++, which results in a proven insulation value of Uw ≤ 0,83 W/(m².K). This minimises the chance of condensation forming and guarantees energy cost savings.
