Processing

Gorter roof hatches with windows provide practical and safe access to flat roofs for maintenance work or to a rooftop terrace. Glazed roof hatches can be installed on flat roofs with a maximum pitch of 5°.

Natural daylight in the room below

Gorter glazed rood hatches are ideal for use in buildings or homes where natural daylight is wanted in the rooms below. This can be apartments with a roof terrace, homes with few windows, office buildings or other non-residential constructions.

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.
