CJ BLOK® PK-25 ENERGO BLOCK 25 25 5N 373x250x248

PK-25

Product Description

The expanded clay hollow block from the ENERGO group is an eco-friendly product made of expanded clay concrete with the addition of perlite. It is recommended for the construction of outer walls of ground and first floors in detached houses. It is also suitable for erecting energy-efficient and passive houses, which have a very low energy consumption. It is characterised by high acoustic insulation, which means that walls made from it absorb noise well indoors. The high thermal resistance and high vapour permeability allow the building to retain heat for longer.  The hollow block has a high resistance to moisture, thus preventing the formation of mould and fungi. Another advantage is very high fire resistance, which increases fire safety. Thanks to the appropriately designed wall thickness and air channels of the hollow block, running electrical and plumbing installations is easy and protects against excessive damage to the element. The relatively smooth surface of the hollow block does not require the need for internal plasters.
