HAVERKAMP bridges gap between heat protection and daylight transmission.

German consumer organisation “Stiftung Warentest” scrutinized sun protection films: Two OPALFILM® types made by HAVERKAMP were among the films tested. The test lab focussed on the question which film would manage to bridge the gap between effective heat protection and a high level of daylight transmission. The test lab’s conclusion recommends sun protection film OPALFILM® Flex N50PX by marking it with “Unser Rat” – “Our Advice”.

“Stiftung Warentest” tests sun protection films


HAVERKAMP bridges gap between heat protection and daylight transmission.

According to the June 2010 edition of the magazine “Test”, this HAVERKAMP sun protection film is one of the few films that achieve a compromise between heat protection and ‘good’ optical qualities that ensure that rooms remain reasonably light.
In order to categorize the films, the test lab simulated the extreme conditions of an attic room. “Stiftung Warentest” used a 20 square-metre room with a roof light (12.5 percent window surface in relation to floor space). As a result, the test lab concludes that films that have an extremely darkening effect should only be installed on glazing surfaces that are generously sized in relation to the room.
Designed for a variety of purposes, HAVERKAMP’s OPALFILM® series succeeds in meeting usage requirements of the test. The heat protection qualities of sun protection film OPALFILM® Flex N20PX were rated “very good” and the optical qualities of OPALFILM® Flex N50PX were rated “good”. Furthermore, the latter film was among the best in the test rubric “Additional heating requirements (in winter)”. Thus, with the variety available, there are types of OPALFILM® sun protection film that meet the specifications of different rooms and situations.
“Stiftung Warentest” tested DIY films as well as films that have to be installed by an expert, like those made by HAVERKAMP. Their recommendation: “Better have it installed professionally.”
