ARC TCB Square for 100mm Cavity - Cavity Barrier around Service Penetrations in External Timber Frame Walls - 115mm x 500mm x 500mm

ARC TCB Square is a faster and easier to install cavity barrier around service penetrations in external timber frame walls of low rise houses. It exceeds the Building Regulation part B fire safety norm EI30/15. ARC TCB Square provides a more robust solution, compared with either boxing in using cut sections of linear cavity barrier, or wrapping linear barriers around the pipe. ARC TCB Square is designed to perform the function of a cavity barrier around openings in the wall. Consists of non-combustible rockfibre mineral wool and outer cover with flanges.

Note: ARC TCB Square is not a penetration seal or a fire stop and does not replace the requirement for this where it exists, for example an intumescent pipe wrap.

• Up to 60 minutes fire integrity,
• Quick and easy installation,
• Robust solution,
• Meets cavity barrier requirements of Approved Document B,
• Suits service penetration sizes up to 150mm diameter,
• Innovative protected design,
• Outer dimensions: 115mm x 500mm x 500mm,
• Fire rating: 60 minutes,
• Insulation performance: 15 minutes.

• The cavity width must be accurate and match the design width for the cavity barrier that has been installed.
• It should be compression fitted within the wall cavity where there will be a pipe penetration.
• It can first be fixed through the flanges at the point where the penetration will be.
• The flanges should be fixed above and below the product to direct water away from the internal leaf of the building.
• Once the service penetration has been drilled and the service pipe has been installed, the product can be placed over the pipe. 
• The outer brickwork can then be laid creating the cavity and compressing the ARC TCB Square to its required fit.

• Third-party certificated by IFC, number IFCC 1841
