Sourcing NHBC-compliant products is vital when specifying glazed curtain walling for housing projects given the strict regulation governing these major installations. Compliant products also minimise the risk of problems arising once the walling has been installed.
VELFAC composite aluminium / wood glazing is one of the few systems on the market that guarantees NHBC-compliant performance while also delivering energy efficient, architecturally stunning curtain walling at a price equivalent to all-aluminium. VELFAC CWCT test results satisfy Chapter 6.9 of NHBC Standards and meet CWCT-specific levels of weatherability performance when curtain walling passes over floor slabs.
To ensure this level of quality and reliability, VELFAC has worked closely with CWCT for many years, developing testing rigs and testing sequences designed to push the VELFAC product range to its limits. The resulting performance data meets NHBC Chapter 6.9 Standards, a rare achievement for a window manufacturer and clear evidence that the VELFAC system can deliver the levels of air, wind and water resistance required to withstand the climatic conditions defined by NHBC as ‘very severe’. In addition, the VELFAC factory process includes the required controls regarding in design documentation, while the company also offers a 12-year warranty on its products, one of the best from any window supplier in the market today.
