Processing

 

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°.

 

Fire rating

The integrity of the fire-resistant steel Gorter roof hatch has been assessed by Efectis according to EN1634-1, EN1530-4 and BS476: part22.

 

Classification:

EI 1: 120 minutes

EI 2: 120 minutes

E: 120 minutes

 

Standard verions

The fire-resistant roof hatch is available in eight standard sizes and special sizes up to 1000 x 2000 mm.

 

Fully thermally broken

The fully thermally isolated curb and cover have a high insulation value and so minimise the chance of unwanted condensation forming while also saving energy costs.
