    Gorter® Explosion Vent - Roof Access Hatch - RHTX

    An explosion vent roof hatch - also known as an explosion vent or explosion hatch - has an Explosion Release Control (ERC) which ensures that the hatch unlocks automatically in the event of an unexpected pressure build-up. The opening pressure is 100 kg. In addition to explosion vent roof hatches, Gorter also supplies explosion vent hatches for façades.

    Explosion vent hatch usage
    Gorter explosion vent roof hatches can be installed on flat roofs with any pitch. The cover of the hatch must not be impeded by obstacles inside or out.

    Fully thermally broken
    The Gorter explosion vent roof hatch has a fully thermally isolated curb and cover, and a proven high insulation value. This minimises the chance of condensation forming and guarantees energy cost savings.
