ARC Eco-Closer closes the cavity around window and door openings in masonry walls, providing up to one hour fire integrity. The rigid PVCu profile is insulated with Non-Combustible rockfibre mineral wool which provides fire, thermal and acoustic properties.

ARC Eco-Closer 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.

The ARC Eco-Closer is easily installed. Simply 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. If a longer length than 2.4m is required
