4.   Measure the inner window gap size at the top in the tilt 

position in cm. The gap size of your window may not be 
less than the gap size obtained from the table. An even 
larger gap or window opening is preferable.

5.   If the window‘s gap size is less than the permitted value 

according to the table then it may be that the window 
can only achieve the required gap size in the turning 
position. Even in the turning position, a minimum gap 
size must be achieved. The window contacts must be 
mounted so that maintenance of the minimum gap size 
is assured. We recommend that the minimum gap size is 
fixed by means of a spacer.

1.   Find out the air extraction throughput of your air 

extraction device in m³/h. You can find this on the type 
plate or in the manual for the air extraction device 

  (e.g. air extraction hood).

2.   Measure the internal width and height of the window 

and work out the window size in m².

  (width x height = m²; e.g. 0.8 m x 1.0 m = 0.8 m²) = 

window size

3.   Read off the window gap size (minimum gap at side of 

your window) where the air extraction throughput and 
window size intersect on the table.
