The smoke extraction system consists of:

The basic element of the system is the VELUX smoke ventilation window. The windows are available with standard NCS S 7500-N aluminium cladding and safety glass -70.
On special request, the windows are available with copper or zinc titanium cladding, and energy-saving two-chamber glass -66.

Important note:

It’s necessary to choose a sealing flashing for window, which is an essential element when you install the window. The flashing is selected depending on the roofing (e.g. roof tile type, thatch tile, steel tile, shingle, roofing felt etc.) and roof pitch. Flashing is used to seal the window and drain water and snow beyond its outline.

In case of installing the windows without standard flashing, it’s necessary to order the ZWC flashing.
