The Gorter fire-resistant steel roof hatch provides practical and safe access to flat roofs and at the same time, when closed, provides a fire-resistant seal for the space below. Roof hatches can be installed on flat roofs with a maximum slope of 5°.
The integrity of the fire-resistant steel Gorter roof hatch has been assessed by Efectis according to EN1634-1, EN1530-4 and BS476: part22.
EI 1: 120 minutes
EI 2: 120 minutes
E: 120 minutes
The fire-resistant roof hatch is available in 6 standard sizes and special sizes up to 1000 x 2000 mm.
