Description

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.

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. The insulation value is calculated for the entire construction (Uw), not just the insulation material.
