THE AIR-IN^® TEST LABORATORY FOR TESTING
WINDOWS AND VALVES

Our other laboratory allows any valve/window structure to be studied under conditions corresponding to reality. The laboratory has been constructed to be extremely air-tight, thereby always creating reliable measurement results. The total leak rate of the laboratory is only 0.14 l/s / 29.5 square meters or 0.004 l/s / square meter, and the measurements are carried out using an under pressure corresponding to the use of the products in flats.

In the laboratory, the heat recovery of a 4-glass Fenestra window with an Air-In® valve was tested:

Monitoring of heat recovery in the Fenestra test window, February 2011 – March 2011U factor of the window 0.83, maximum difference between outdoor temperature and inblow 20.6°C

The laboratory is an example of the possibilities window manufacturers have for testing various window structures and valve solutions. Please contact us if you are interested in our research services!

The Air-In® laboratory also offers a unique possibility to see how the comfort of living can be improved by means of frequency regulator operated constant pressure regulators. They allow constant air volumes in flats even when other inhabitants block valves in other flats. The amount of air stays stable and does not grow as in an unregulated situation.
