Strict requirements are set by various governments when it comes to the fire-resistance of buildings, the aim being to limit the fire and prevent accidents. It is often stipulated that buildings must be compartmentalised. This means that the building is divided into fire and smoke compartments, each of which must keep the fire inside the compartment for a specific time (30, 45 or 120 minutes). This is achieved by having fire-resistant partitions between the compartments in accordance with the applicable legal requirements. The floor door plays a major role in this separation because it also prevents the fire from spreading to a lower or an upper space.

The WAEI type hinged floor doors are safe to operate with one hand, allowing the other hand to hold a handrail, ladder or stairs, for example. The counterbalance system helps with opening and slows closing. In addition, the automatic locking mechanism in the open position makes sure the floor door cannot slam closed by accident.



The Gorter WAEI fire-resistant floor door is available in four standard sizes and special sizes up to 1000 x 2000 mm. The steel hatch is EPD treated and powder coated for a long service life.


Combination with ladders and stairs

Depending on the size and application, WA types of floor doors can be combined with a fixed vertical ladder, an extension ladder or a fixed staircase. A scissor stair can be used in some cases.
