Knauf Insulation Earthwool Dritherm 37 Standard Cavity Slab 100mm x 1200mm x 455mm

H+HÕs Celcon Blocks High Strength Grade (7.3N/mm2 Ð identified with a black stripe on the block) is ideal where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings.

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. Identified by the distinctive painted blue line, Celcon Solar Grade has a compressive strength of 2.9N/mm2 and is principally used where enhanced thermal performance is required.

The pressed concrete slab from Marshall's is widely used by the public in high volume pedestrian areas. The pimples on the surface create an added traction for maximum slip/skid performance. Manufactured using local aggregates to minimise unnecessary haulage, it is a functional landscaping essential. The natural colour may vary and the concrete slab comes in four different colours to choose from.
