ARC TCB for 100mm Cavity - Cavity Fire Barrier for Timber Frame Construction - 115mm x 120mm x 1200mm - Pack of 15

115mm x 120mm x 1200mm ARC TCB for 100mm Cavity is a non-combustible rockfibre mineral wool cavity barrier that restricts the spread of smoke and flames within the cavity of external and internal party timber frame walls. It is ideally suited for providing a cavity fire barrier within the external wall cavity, in line with a separating wall or floor as specified in Approved Document B. It also minimises the effect of flanking noise pollution. Typically the ARC TCB is mechanically fixed to the timber frame structure, with the brick work then laid creating the cavity and compressing the ARC TCB to its required fit. as the relevant Cavity TCB is 15mm wider than the given cavity for the compression fitting. 

• Up to 60 minutes fire integrity,
• Can be installed horizontally and vertically,
• Easily installed with compression fit,
• Can be used around window and door openings,
• Specified in terraced, semi-detached, apartments and major projects,
• Meets requirements of Robust Detail Part E and Approved Document B.

• Nail the polythene flanges to fix the ARC TCB to the timber frame inner leaf.
• Clout nails or staples should be used at 150mm centres.
• Horizontal application: it is only necessary to use the flange running along the top of the barrier
  
• Vertical application: use both flanges.
• At the end of a run, or at a corner, lengths of ARC TCB should be cut to the required length, and then tightly butt jointed ensuring no gaps remain.
• Brick work can now be completed, closing in the ARC TCB within the cavity, ensuring that the fire barrier is compression fitted..
