B.O.S.S. A1 is a lightweight, carbon neutral, prefabricated brick slip soffit system designed to be quickly and easily bolted to IG’s Welded Masonry Support (WMS) to create deep reveals, soffits and flying beams on masonry facades. This BBA certified unit is manufactured completely from A1 fire rated materials and is Document B:Fire Safety compliant. Manufactured offsite, the prefabricated components are delivered to site complete with brick slips adhesively bonded and mechanically secured to the brick carrier unit.
The lightweight system facilitates fast and efficient installation reducing installation times by up to 90% and negating the need for mechanical lifting as B.O.S.S. A1 is 70% lighter than equivalent concrete units.
The system is an ‘A1’ fire rated, BBA certified unit suitable for use on projects that require Document B compliance. By specifying B.O.S.S. A1,
architects and specifiers can be assured that their brick soffit features meet current fire regulations regardless of the building’s height or purpose.
The B.O.S.S. A1 units were tested to demonstrate structural performance, following a period of accelerated weathering. The bond strength
of the system was evaluated after being subjected to hygrothermal conditioning. The testing involved subjecting the B.O.S.S. A1 units to repeated
heat / rain cycles, followed by repeated freeze / thaw cycles at a controlled temperature and humidity, all designed to simulate naturally occurring
conditions. Following the weathering, pull-off tests were performed on the B.O.S.S. units.
B.O.S.S. A1 has achieved Carbon Neutral Standard by offsetting carbon emissions through certified carbon offset projects.
B.O.S.S. A1 is available in many profiles, four of which are shown below. Bespoke solutions including other brick
arrangements can be designed to suit specific project requirements.
