Our fire testing station

Fire doors generally require the approval of national authorities. Approval is usually granted after testing operating door sets by official test institutes.

Since these tests tend to be very cost and time consuming, our Service Centre offers preparatory testing and advice.

Our sound testing station

Sound insulation is tested in compliance with DIN EN ISO 140 in testing stations, which are acoustically fully insulated.

Sound is transmitted exclusively through the tested door and not through openings or the walls and ceilings. Test results of door leafs sealed to the frame by putty are not of particular importance for the user.

Tested safety

Independent institutes monitor the products and carry out performance tests.
Constructions using SAUERLAND materials have been tested and certified by official institutes all over the world.
