Independently tested and approved by the BRE
No other manufacturer has ever submitted its roofing adhesives to the Building Research Establishment (BRE) for testing. In Spring 2012 IKO delivered three test samples to BRE in Garston, UK. Each roof section sample was mounted in a pressure chamber and subjected to over 1,400 suction loading cycles up to a maximum of -5,500Pa. This figure represents the most extreme wind loading expected during a roof’s lifetime and provides a realistic test of wind load performance. For comparison, a typical city wind loading is -1,000Pa, while an exposed coastal loading is -2,000Pa. Each IKO sample reached at least -5,000Pa before the first signs of failure, giving a roof “safety factor” of 2.5 for coastal areas and 5 for cities.
