Product description
This Fire Barrier slab has been developed to prevent the spread of flames and inhibit heat and smoke through concealed spaces in buildings and improve sound reduction.
The thicker the board the more time the fireboard will hold up and not deteriorate in the event of a fire. For instance, a 15mm fireboard will last for up to 60min,
12mm will last 45 minutes, 9mm will last one half an hour, and so on. Remember, if there is a hole in the board to allow for wiring, this will eliminate the protection that the fireboard provides.
When used in a partition or ceiling, two layers of 12.5mm fire plasterboard should provide up to one hour’s fire protection.
In a partition where there are two layers of fire-rated plasterboard on either side, they will provide up to two hours of fire resistance.
