British Gypsum Gypfloor SILENT SIF2 Floor Channels (10 pcs)

British Gypsum Gypfloor SIF2 Floor Channel is integrated with a specially designed neoprene acoustic insulator, conforming to EN 14195, made to provide support for the Gypfloor SILENT floor system, which is applicable to both refurbishment and remodelling projects on timber joist floors and new build and construction to provide an overall improvement in acoustic insulation, all in order of allowing your internal floors to meet the prescribed requirements of applicable Building Regulations. The system provides sound insulation from both impact and airborne noise but minimally increases the floor depth (adding only 7mm to the top joists level). It is advised that ceiling linings should be properly fixed before applying plastering or dry lining, while in remodeling projects, the upper surface of the joist should level with the flooring (which can be done by using GypLyner UNIVERSAL which will support the ceiling boards). In order of making sure that the structure will meet the prescribed values, consideration should be given to the surrounding structure and floor type.
