H+H Celcon Solar Aerated 2.9N Concrete Block 100mm - Pack of 120

H+H Celcon Solar Aerated Concrete Block 2.9N is only available from us in the one size of 440 x 215 x 100mm. This highly This highly efficient block (thermal conductivity of just 0.11 W/mK) is sufficiently loadbearing for two storey buildings and can be used below DPC. Grade has a compressive strength of 2.9N/mm2 and is principally used where enhanced thermal performance is required. These blocks have superior thermal conductivity and provide a cost effective solution to energy conservation. They are extremely versatile and can be used in a number of situations. They can be used for internal and external cavity walls, solid walls, flanking walls below DPC and partitions. Do not require any additional insulation material with a fire rating of Class A3. For a higher strength concrete block to use in building foundations, see Celcon Hi-7 Aerated Concrete Block 7.3N.
