ENERGO building
External Walls
When choosing the material for the walls of the residential floors, it is important to remember two essential wall performance characteristics.
Namely, all external walls must be characterised by very good thermal and acoustic insulation. The ideal material that has high thermal resistance and high vapor permeability and allow the building to retain heat for longer is light and quiet PK-25 ENERGO expanded clay block presented below.

Foundation walls and basement walls
For the construction of foundation walls and basement walls, foundation expanded clay blocks are used.
The of 1m2 surface of a wall made of these elements is twice as small and has four times better thermal insulation than walls made of typical foundation blocks. Better thermal insulation reduces expenses for additional costly insulation of walls in the ground and in the plinth area. Thanks to the higher thermal insulating of the expanded clay partition, the insulation used to insulate the foundation walls can be 4 cm thinner.

Acoustic interior walls
The best properties in terms of protection against noise penetration between rooms are obtained with the use of solid acoustic blocks.
Full expanded clay- concrete blocks make it possible to obtain sound insulation above 55 dB, and a minimum value of 50 dB is required for walls located between apartments in multi-family housing. However, also in single-family housing, the acoustic wall allows you to create quiet rooms within one house. The acoustic blocks can be used to erect structural walls loaded one or both sides with the ceiling structure.
BL AQ18g2
Dimensions (L x W x H): 380 x 180 x 248 mm
Compressive strength: 15 MPa
Sound insulation Rw: 55 dB
Sound insulation R’: 53dB
Fire resistance: REI 240
Thermal conductivity coefficient: λ = 0.62W/mK
Reaction to fire: Euroclass A1
Consumption of 1m2 with a joint thickness of 3mm: 10.7 pcs

Partition walls
One of the most important technical parameters for partition walls is also the parameter of acoustic resistance Rw, which must be achieved with the thinnest possible wall for eco-nomic reasons.
In this case, we use PK AQ-12 hollow blocks, which are perfect as separating partitions and dividing walls between rooms, where the acoustic insulation is 47 dB.
