B.O.S.S. A1 is an A1 fire rated, carbon neutral, prefabricated brick slip soffit system designed to be quickly and easily bolted to IG’s Welded Masonry Support (WMS) and steel lintels to create deep reveals, soffits and flying beams on masonry façades.

Manufactured offsite, the prefabricated components are delivered to site complete with brick slips adhesively bonded and mechanically secured to the brick carrier unit. The BBA-certified components are designed to be installed and integrate seamlessly with brickwork constructed onsite.

B.O.S.S. A1 is manufactured completely from A1 fire rated materials and is Document B:Fire Safety compliant.

B.O.S.S. A1 (Brick on Soffit System)

Designed to be bolted to WMS and Steel Lintels

Available in various bond patterns

Application

Brick soffits, deep reveals and flying beams have become increasingly popular design features with architects wanting to add depth and visual flare to a masonry façade. IG’s B.O.S.S. A1 provides a technically advanced solution that meets the required aesthetics, producing completely hidden structural steel work which gives the impression of unsupported brickwork.

Certifications and Accreditations

A1 Fire Rated

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.

B.O.S.S. A1 Typical Design Solutions

B.O.S.S. A1 creates spectacular brick soffits with a wide range of bond patterns and soffit sizes achievable.

Typical design solutions include:

Header Bond
This solution is used to create header details at openings and reveals. The header bond detail on the B.O.S.S. A1 unit differentiates the soffit from the brickwork on the main façade.

Stretcher Bond
This solution is used to create deep soffits providing continuity with the brickwork on the main façade. Adjacent soffit units are designed to interlock, blending seamlessly together once the brickwork is pointed.

Half Lap Bond
This solution is used to create half lap bond details at openings and reveals. The half lap bond detail on the B.O.S.S. A1 unit differentiates the soffit from the brickwork on the main façade.

Soldier Bond
This solution is used to create soldier bond details at openings and reveals. The soldier bond detail on the B.O.S.S. A1 unit differentiates the soffit from the brickwork on the main façade.

Bespoke solutions including other brick arrangements are designed by our engineers to suit specific project requirements. Please contact our Technical Team for further information.

Adjustability

B.O.S.S. A1 is designed to be fitted to the underside of IG’s Welded Masonry Support (WMS) and steel lintels and offers adjustability on all three planes.

Horizontal adjustment (X)
Horizontal adjustment can be achieved by utilising the channel on the B.O.S.S. A1 unit and simply moving the unit from left to right.

Vertical adjustment (Y)
Vertical adjustment can be achieved by inserting stainless steel packers between the Welded Masonry Support or steel lintel system and the B.O.S.S. A1 unit under shelf angle.

Lateral adjustment (Z)
Lateral adjustment is achieved by utilising the slotted hole located on the shelf angle or lintel. Adjustment provided is +/-15mm. Once alignment and levels are correct, bolts should be torqued to 31.5 Nm as per Construction Issue Drawing provided by IG Masonry Support.

Product Design and Testing

B.O.S.S. has been independently tested by Third Party Organisations and Technical Approval Bodies to evaluate and validate the physical performance and long term durability of all components as well as ensure the products are fit for purpose and conform to regulations.

Key factors assessed by the British Board of Agrément (BBA), including properties in relation to fire, structural performance, thermal performance, condensation risk and durability can be found in Product Sheet 5: IG B.O.S.S A1.

Hygrothermally Tested

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.

Carbon Neutral Product

B.O.S.S. A1 has achieved Carbon Neutral Standard by offsetting carbon emissions through certified carbon offset projects.
