Firetherm Fire Batts are used on large and small fire protection projects throughout the World.
Produced from super-high density (180 kg/m3) mineral fibre to complying with EU Directives 67/548/EEC and 97/69/EC.
It is used to seal holes in fire compartment walls and floors around services such as air-conditioning ducts, pipe work and electrical cabling against the passage of fire and can provide up to 4 hours integrity.
Tested at Warrington Fire Research to BS 476 Part 20/22. 4 Hour Fire Integrity on a single Batt.
Up to 120 minutes insulation one board thickness, 240 minutes - two board thickness.
The 1200x600x50mm size provides excellent value for money and lower installation costs. Its 50mm thickness means low overall weight making for easier handling.
Clear any debris or contaminants from the opening.
Mask around the opening with masking tape allowing a 25mm margin if necessary to provide a neat clean edge to the finished job. Measure opening and transfer measurements to the face of one or more Intubatts.
Using a serrated knife, padsaw or hacksaw blade, cut the Intubatt into suitably sized pieces to ensure a snug fit into the opening. Intubatt seals can also be installed as a "patress" or surface mount provided there is at least 100mm overlap onto the wall face and the batts are mechanically fitted with steel anchors, masonry nails or similar, at 200mm centres, fitted with large headed washers.
Apply Intucoat mastic in brush, trowel or cartridge grade, depending on preference, to the inside of the opening to bond the Intubatt to the masonry.
Apply further Intucoat to the penetrating services where they will make contact with Intubatt.
Dry fit cut pieces when access available from both sides for mastic pointing.
When installing cut pieces from one side only "butter up" the cut edges with Intucoat mastic to bond the pieces together.
Intucoat is an exceptionally effective adhesive and will create a strong bond when cured.
Some temporary support may be required while Intucoat cures.
It is vital that the seal is strong and secure on final inspection.
This strength must not be compromised by poor construction techniques.
With a paint brush dipped in water, brush out the Intucoat mastic onto the masking tape if used.
Remove the tape before mastic has cured.
Place off cuts and debris in strong plastic bags for disposal.
