Processing

Gorter removable roof hatches are fitted with two or more lids depending on the dimensions. The removable roof hatches do not have hinges but can be lifted with a crane by means of the lifting eyes (4 per hatch). When the lids are removed, there is a clearance in the roof through which material can be brought inside. The removable roof hatches can be used on flat roofs.

Dimensions

Gorter removable roof hatches are available in almost all daylight sizes and can be fitted with a split edge.

Fully thermally separated

The Gorter RHT flat lid removable roof hatch is fully thermally separated and has a proven high insulation value; Uw ≤ 0.319 W/(m².K). This minimises the risk of unwanted condensation and saves on energy costs.
