CJ Blok® PK-12 EXPANDED CLAY BLOCK 5N 390x120x190

Product Description

Expanded clay and perlite hollow block offers high quality and perfect durability due to the use of these two materials. This eco-friendly product is perfect for building partition, basement and single-leaf walls. For the material used, the hollow block is relatively lightweight. Thanks to its porous structure, insulates heat very well and has high vapour permeability, protecting the building from moisture. It has good thermal insulation and thermoregulation properties, making it resistant to both frost and fire. Its surface is relatively smooth, so there is no need for applying interior plasters. Walls of the hollow block should be built for horizontal and vertical joints. This product is easily processed (sawing, cutting, drilling).
