Installation time is half that of a conventional taped and sealed system, according to BSRIA tests, with costs reduced by 20%.
The tests also shpwed a leakage rate 43.8% of that from a system using traditional components — at 500 Pa.
The Lindab SR Cutter is an essential accessory. Two measuring scales in the cutting table enable sections of duct to be cut to precisely the required length. The mechanism ensures a precise, clean cut every time.
