For roof terrace, office and home

RHT roof hatches can be used as escape hatches, but in most situations, they provide a convenient access to roof terraces, cooling installations, lift machine rooms, window cleaning installations, solar collectors, and other facilities on rooftops. The RHT roof hatches can be installed on flat, insulated or non-insulated roofs made from concrete, steel or wood with a maximum roof pitch of 30°.

Safety first with a Gorter roof hatch

All Gorter roof hatches and combinations are safety tested to the most stringent EN standards and are supplied where appropriate with a TÜV NORD certificate, Aboma safety mark and KOMO® certificate.


One of the safety features is the hand rail in a yellow finish characteristic of Gorter, which provides a secure grip when accessing or exiting the roof. Another safety feature is the automatic locking in the open position making sure the roof hatch cannot slam down shut unexpectedly. In addition, the Gorter retractable and removable stairs/ladders such as the scissor stair and ladder can be locked easily when in use.
