SILKA ‘big blocks’ – more than just quicker build times

SILKA calcium silicate ‘big blocks’ of up to 1000 mm x 645 mm are used for load bearing, non-load bearing and inner leaf cavity walls.

Two men can lay 60m2 / day from the building interior, saving time and cost of scaffolding. A single leaf 150mm wall provides an acoustic value of 50-55dB compared to 44dB for an unfinished 140mm aircrete block. Blocks provide a 120 minute fire rating compared to SIPS at 30-60 and sufficient thermal mass to absorb heat and release it slowly, helping maintain a healthy living environment.
