Typical 10mm non-fire rated plaster board or so called 13mm fire proof plasterboard as well as single sheets of plasterboard cannot meet high-rise and commercial building FRL Fire resistance levels over 60 ,90 and 120 minutes, without the need for multiple layers of fire proof plasterboard in fire separation walls.
The 10mm FireCrunch fire proof building board will however move the fire resistance level to FRL 90/90/90 with one 10mm MgO sheet each side of a 92mm steel framed fire separation wall or double stud timber frame. This results in a huge reduction of direct costs in material; more so the expensive labour rate per m2 to install, at least double, and in some cases three layers on each side. The extra hidden costs of the extra site work can increase time and delivery fees for double and even treble the material handling. This should not be overlooked and can vastly help to improve the all-important ROI for the developer builder.
