CJ BLOK® BK-30/28 EXPANDED CLAY FOUNDATION BLOK 380x240x240

foundations blocks

Product Description

The high-class ecological expanded clay block of the ENERGO group with an admixture of perlite allows for the construction of modern technology buildings. Walls made of this block have 4 times higher thermal insulation than walls made of typical concrete foundation blocks. Thanks to these properties, it is great for building single-leaf walls, foundations and basements. The block is very lightweight and has excellent thermal insulation and high vapor permeability, which means that a thinner layer of insulation can be used. Another important advantage of the product is its very good sound insulation and high resistance to fire, frost and moisture. In addition, its smooth surface does not need plastering. Very precise workmanship allows for using thin-layer mortars.
