ARC TCB115 Flanged Cavity Barrier 130 x 150 x 1200mm (Bag of 12) by ARC Building Solutions

ARC TCB115 Flanged Cavity Barrier 130 x 150 x 1200mm (Bag of 12)

The ARC TCB115 Flanged Cavity Barrier is engineered to deliver exceptional fire protection in timber frame constructions. It provides up to 60 minutes of fire integrity and 15 minutes of insulation, ensuring the safety and resilience of your building. This barrier measures 130 x 150 x 1200mm and is suitable for cavity widths up to 115mm. Each bag contains 12 pieces, making it a cost-effective solution for extensive construction projects. The barrier is constructed from non-combustible rockfibre mineral wool with a thermal conductivity of 0.037W/mK, and is encased in a durable polythene sleeve for added weather protection and ease of handling.

Installation Guide:

Option 1: Fixing to Timber Frame Before Brickwork

1. Prepare the Barrier:
   • Measure and cut the barrier to the required length if necessary.
   • Use the polythene flanges to fix the ARC TCB115 to the timber frame inner leaf.
2. Fix the Barrier:
   • Secure the barrier using clout nails or staples at approximately 150mm centers.
   • For vertical installations, use both flanges. For horizontal installations, use only the top flange.
3. Ensure Tight Fit:
   • Butt joint lengths tightly at the end of a run or at corners to ensure no gaps remain.
4. Complete Brickwork:
   • Lay brickwork to create the cavity, compressing the ARC TCB115 to its required fit.

Option 2: Building in as Brickwork Progresses

1. Prepare the Brickwork:
   • Build the brickwork up to the level where the barrier will be installed, ensuring the cavity width is correct.
   • Allow the brickwork to set.
2. Install the Barrier:
   • Push fit the barrier into place under the correct compression.
   • Butt joint lengths tightly at the end of a run or at corners to ensure no gaps remain.

General Tips & Advice:

• The polythene encapsulation and flanges help hold the barrier in place and offer weather protection, but do not contribute to the barrier's performance. Leave the polythene intact.
• Ensure the cavity width matches the design width for the installed barrier.
• Avoid squashing the barrier before installation, as this can cause gaps and reduce performance.
