Kawneer window passes CWCT test

An AA720 tilturn window from aluminium systems supplier Kawneer has justified the UK manufacturer’s faith in it by passing an extreme weather test, it says.

The CWCT (Centre for Window and Cladding Technology) Standard Test Method for Building Envelopes: December 2005 was carried out by UKAS-accredited testing house Wintech on a 6300mm x 8000mm high sample size of Kawneer’s AA100 and AA100 HI curtain wall system.

Although it is not a requirement, Kawneer says that it tests all of its curtain wall systems to CWCT with an opening window incorporated into them. Previous successful tests have included an outward- opening window; as such windows are often viewed as offering better weather performance, Kawneer says.

Kawneer says it had “so much faith” in its inward-opening 1326mm x 1601mm high AA720 HI Reflex tilturn window, that it was incorporated into the screen for the CWCT test and both window and curtain wall “passed with flying colours”.
