Rectangular duct profiles exceed TM/1 air leakage

Tests carried out by BSRIA have confirmed that Lindab’s Euroflange range of rectangular duct profiles meet all the requirements of DW/144 Class A, B and C air-leakage limits. These flange systems incorporate a flexible rubberised compound. When assembled, the duct cuts into this membrane to provide a seal that under test conditions exceed TM/1 air-leakage specifications. The Euroflange range is available with a choice of clamps, knock-on or drive cleats to conform with Euro-20/30/40 in J2/3/4/5/6 Standards. They are generally made of galvanised steel and supplied in 5 m lengths. Other sizes and materials are available on request. Tel. 01604 707600
