Smoke lock

EI1 30, 60, EI1 120, EI1 180, EI2 60, EI2 120, EI2 180 and EI2 240 – fire resistance from 30 to 240 minutes. (EN 16341-1 S)

In the event of a fire, building elements must continue to perform their function despite any fire damage. The structural elements must remain stable throughout the period necessary to evacuate the building. The walls and doors separating the different partitioned areas of the building should limit the spread of fire. Winlock can halt the spread for up to 240 minutes. Openings in the building are the weak point in terms of fire compartmentalisation.

The evacuation of people and the work of the emergency services is much more effective if the air is fit for inhalation and does not restrict visibility. Thanks to expanding seals (which swell in contact with heat) developed by Heinen, and certified smoketightness, Winlock doors prevent the spread of fire and the often deadly smoke.

Metal+, the basis of every Winlock door!

The distinctive feature of the Metal+ concept is its modularity: each door is characterised by the same sturdy structure, allowing numerous properties and features to be combined in a single interior or exterior door! Regardless of their features, WINLOCK doors always have the same appearance.
They can be finished in top-quality galvanised steel, stainless steel or RAL colour. The separate parts of the door assembly are screwed (not welded), which is possible thanks to the encircling internal frame. This ensures exceptional strength leading to minimal maintenance. After damage or vandalism, parts (such as the hinges or cover plates) can easily be replaced or realigned.
