Fire Resistance

Mannok thermal blocks provide excellent fire protection in both load bearing and non load bearing applications. They are classed as non combustible and have a Class 0 resistance to surface spread of flame and category A1 in accordance with BS EN 13501-1. Block thicknesses required for fire resistance periods are shown in the table below.

	6 Hours	4 Hours	3 Hours	2 Hours	90 Mins	60 Mins
Load bearing single leaf wall	215mm	180mm	140mm	100mm	100mm	90mm
Non-load bearing single leaf wall	150mm	100mm	75mm	63mm	63mm	50mm
Load bearing cavity wall	150mm	150mm	140mm	100mm	100mm	90mm
Non-load bearing cavity wall	90mm	75mm	75mm	63mm	63mm	50mm
