ARC Eco-Closer Plus closes wider cavities around window and door openings in masonry walls, providing up to one hour fire integrity. The rigid PVCu profile is insulated with foil faced non-combustible rockfibre mineral wool which provides fire, thermal and acoustic properties.
ARC Eco-Closer Plus has been fire tested at Warrington Fire Research, achieving up to one hour fire integrity with traditional masonry brick and block construction. These tests comply with BS 476: Part 20: 1987. Certifire scope: CF5410.
Where usage falls outside of this scope, for example when used with external cladding, or with an internal metal frame system, performance of the fire barrier will depend upon the structural integrity and fire performance of the surrounding construction.
ARC Eco-Closer Plus is easily installed. Cut the jamb profile to the height of the window or door opening plus 75mm to allow the bottom edges to drop into the cavity below the sill. Once the jamb sections are installed, measure the required width for the sill section and cut a length to butt tightly to the jamb sections.
ARC Fixing Brackets should be used to mechanically fix Eco-Closer Plus to the inner blockwork, while ARC Brick Ties are then used to build the closer in as the external brickwork progresses. We recommend a minimum of 2 of each is used per metre, or piece, whichever is shorter.
If a longer length than 2.4m is required, the profile complete with insulation should carefully be cut using a hand saw. Lengths can then be tightly butted together, with care being taken to ensure no gaps remain.
