An AA®720 tilturn window from leading architectural aluminium systems supplier Kawneer has justified the UK manufacturer’s faith in it by romping through an extreme weather test.
The CWCT (Centre for Window and Cladding Technology) Standard Test Method for Building Envelopes: December 2005 was actually being carried out by UKAS-accredited testing house Wintech on a 6300mm x 8000mm high sample size of Kawneer’s AA®100 and AA®100 HI curtain wall system (report number DPP/R16140).
Although it is not a requirement, Kawneer 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 had so much faith in its inward-opening 1326mm x 1601mm high AA®720 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.
This gives specifiers additional reassurance of the AA®720’s already premium performance in refurbishment as well as new-build projects in the residential, commercial, healthcare, education, and retail and leisure sectors.
The system was tested for air leakage (600 Pa), water penetration (600 Pa), and wind resistance (2400 Pa), a single drop of water ingress being a fail. The pressure on the screen is also raised to 3600 Pa (approximately 160mph) as part of the safety testing and again, the test was passed without any issues.
