Low-to-medium density blocks with good insulating properties ideal for use in external and internal block walls. Superlite blocks can achieve high thermal values using limited amounts of secondary insulation.
Exposed conditions
Superlite Background blocks are a robust product, which can be used in exposed conditions. 7.3 N/mm² products are also suitable for use in aggresive soil conditions. Please contact our Product Services department for further details.
Strength
The strength of Superlite blocks dictates their application in exposed conditions. Block strengths of 7.3 N/mm² and greater should be specified if these blocks are to be used on the outer leaf of a cavity wall below dpc level and left unprotected. In all other normal situations 3.6 N/mm² blocks would be suitable.
Thermal
Superlite blocks in conjunction with suitable thicknesses of insulation, are able to reach high levels of thermal insulation.
Fire Concrete is an excellent fire resistant material. Superlite Blocks are manufactured using Class 1 aggregates which provide the highest level of fire resistance for a given size.

*Block weights are calculated using specified dry density, with a moisture content of 3% by weight added to provide the equilibrium value.
**Weight of erected wall (including mortar). Add 11 kg/m² per side for a 2-coat lightweight plaster finish (24 kg/m² for dense plaster).
