The leading domestic smoke ventilation window in your selection.

Yes, it depends on local legislation. In the Finnish Land Use and Building Act, it is specified that a CE marking is mandatory for all construction products for which there is a harmonized European product standard. Smoke ventilation windows have their own standard, EN 12101-2.

No. The CE marking requires testing six different characteristics for the window and opener system. These required tests are conducted only with an electrically operated opener, so windows equipped with a mechanical opener cannot be granted a CE marking. We consider the CE marking essential, and therefore, we do not manufacture smoke ventilation windows that do not meet these requirements.

No, because the tested models have been outward-opening and bottom-hinged. These smoke ventilation window models achieved the most effective smoke extraction and the most durable structure.

Each CE-marked smoke ventilation window has its own aerodynamically free area specified in the performance declaration or its annex. The key parameters include the flow coefficient determined by product-specific testing, as well as the geometric area of the opened window. Generally, it can be stated that larger smoke ventilation windows are more cost-effective than multiple smaller ones.

Often, we offer an automation package as an option for the windows, which includes a control center and a button solution. In addition to these components, cable work needs to be done between the components, and finally, the power supply must also be connected.

A remote button is a multifunctional switch that serves as the trigger button for smoke ventilation. Under the cover of the remote button, there is also an acknowledgment button for the trigger and ventilation functions.

The ventilation functions allow for convenient inspection and maintenance. Otherwise, these features/buttons are on the control center’s circuit board. When ordering, the remote button can be replaced with separate ventilation and smoke extraction buttons, with the smoke extraction button placed near the door and the ventilation button, for example, in the technical room.

Yes, they can, when choosing a fixed interior window with opening frames.

Frames between 75 – 210 mm are possible for interior windows, and for smoke ventilation windows, the range is between 120 – 210 mm.

This can be considered on a case-by-case basis.

According to our data, there are cases where the glass Rw value was 37 dB, and the overall window measured Rw value was also 37 dB. We generally use a safety margin of two dB, for example, the glass Rw value is 37 dB, and the window Rw value is 35 dB. However, these are fixed interior windows where the glass is glued to the frame, ensuring air tightness up to Class 4 (maximum tightness), preventing air leakage (sound leakage). Installation of the window in the wall and penetrations must meet the requirements of the acoustician.
