Finlite Blocks
The Finlite Block is manufactured using 100% Pumice and no other aggregates. This gives it a very low density of less than 1000kg/m3 and thus its low thermal conductivity of 0.318W/m oC

Advantages
Fire Resistance
Finite Blocks are non combustible and provide a minimum of 2 hours fire resistance even for 100mm load bearing walls. For 100mm non-load bearing walls the fire resistance is 4 hours.
Plastering & Rendering
Finite Blocks provide an excellent key for plastering and rendering and do not require any special bonding agents.
Plastering & Rendering
Finite Blocks accept all normal fixings as used for dense concrete and can be chased as required.
Mortar Mixes
Finite Blocks do not require any special mortars and an OPC: sand with plaster's ratio of 1:6 is normal.
Sound Insulation
The sound reduction across a 100mm Finlite Block Wall is in excess of 40dB while a 215mm Finlite Block Wall gives a 50dB sound reduction.
