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 and GS55 fixed staircase are suitable for floor heights from 3,000 to 3,370 mm.
