If you are building your dream home, DURISBUILD offers a fast and flexible solution, constructing the shell of your home using The CJ Blok® – an innovative, insulated concrete form that provides a very cost-effective alternative to traditional brick and blockwork.

Naturally, you want your finished home to conform to the highest standards of energy efficiency, thermal insulation, acoustic performance, and fire resistance. But at the same time, you would like to spend your budget on the fixtures and fittings that you can see and enjoy, rather than the building shell itself. Now there is no need to compromise… DURISBUILD use PK-25 ENERGO blocks to build quickly and efficiently saving you money on the shell, that you can spend on the fit-out.

What is CJ Blok® – PK-25 ENERGO?

ENERGO group hollow block is an ecological product made of expanded clay concrete with the addition of perlite. It is recommended for constructing outer walls of ground and first floors in single-family houses. It is also ideal for building energy-saving and passive houses with very low energy demand. It has high sound insulation, which makes the walls made of it well absorb noise in rooms.

High thermal resistance and high vapour permeability allow for longer maintenance of heat in the building. Another advantage is very good resistance to fire that increases the fire safety. There is an option of using thin layer mortars. Thanks to the appropriately designed thickness of the air walls and hollow block air channels, conducting electrical and plumbing installations is easy and protects against excessive damage to the element. The relatively smooth surface of the hollow block results in not using internal plasters.

Why use CJ Blok® – PK-25 ENERGO?

• Quicker and cheaper: The major benefit of using PK-25 ENERGO for your project is the speed with which the shell of the building can be completed – up to 30% less than traditional brick and blockwork.
• Fewer delays: Unlike traditional brick and blockwork, PK-25 ENERGO can be constructed in all conditions avoiding frustrating, and potentially costly delays due to adverse weather.
• No compromise on standards: Exceptionally high thermal efficiency with U-values as low as 0.20, acoustic performance to 51dB.
• Easy hand-over after the shell is complete: Chasing for electrics and plumbing is easy and fast. All flooring systems can be used with PK-25 ENERGO and it can accommodate almost all manner of claddings with it including render, brick slips, brick-effect render, timber and rainscreen cladding.
