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 |
Acoustics
Mannok Aircrete Standard Blocks have a density of 650kg/m3 and so are suitable for use in party wall construction. Guidance on party wall construction can be found in Robust Details or alternatively contact the Mannok Technical Department.
