Materials used to build «ECO-friendly zero-energy houses by KALAHOUSE»™

The materials used by company “KALA” for the complex production and construction of energy-efficient eco-houses “KALAHOUSE”, for the manufacture of interiors and highly artistic furniture from solid wood of valuable species, namely:

Structural materials:

The main structural material in the technology of complex manufacturing and construction of energy-efficient eco-houses “KALAHOUSE” is a composite material of in-depth wood processing, such as LVL, which has significant advantages:

  • The multilayer structure of unidirectional veneer makes it extremely strong and durable;
  • Compared to solid wood, LVL is a completely homogeneous material with unchanged physical and mechanical characteristics throughout;
  • LVL practically does not absorb moisture, so the dead weight of the manufactured beams remains unchanged in a humid environment;
  • Stability of linear dimensions of the material ensures high accuracy of assembly of conjugate beams;
  • High density and absence of cracks provide high resistance to fire penetration into the material;
  • Unlike metal and reinforced concrete, LVL is highly resistant to aggressive environments;
  • The use of LVL I-beams makes it possible to construct large-span floors and create room space without columns and partitions;

“KALA” manufactures load-bearing structural I-beams, mounting and strapping belts, as well as exterior and interior elements based on LVL.

Insulation materials:

For double-circuit multilayer heat and sound insulation of structural elements of the wall system of energy-efficient ECO houses “KALAHOUSE”, plates of non-combustible hydrophobic mineral stone wool, FASAD type, with a specific gravity of 110:150 kg/m3 are used.

For thermal and sound insulation of the floor system, ceiling system, and roof system of energy-efficient eco-houses “KALAHOUSE”, we use slabs of non-combustible hydrophobic mineral stone wool, type UNIVERSAL, with a reasonable weight of 60 kg/m3.

Thermal and sound insulation boards made of mineral basalt wool have high thermal insulation characteristics, low thermal conductivity, high sound insulation, high fire safety, hydrophobicity and long service life, making them the most highly efficient insulation material.

Finishing materials:

Valuable wood is used to make interior and exterior elements, window and door systems, and highly artistic furniture, namely

Oak

Oak timber has high strength, is rot proofing, insect-resistant and flexible, has beautiful texture and colour.

Robinia

Robinia timber has nice appearance and texture, is tough and rot-resisting. It has better physical and mechanical properties than oak and ash.

Ash

Ash wood is tough and viscous. It has low tendency to cracking, good deflectability and beautiful texture.

Walnut

Walnut timber has nice colour, pattern and high mechanical properties.

Basswood

Basswood timber is soft and light. It has compact texture, is good for wood working, rarely cracks and warps.

Pear

Pear timber has beautiful brown-pink colour and homogeneous structure. It is of high density and is good for wood working and polishing.

Cherry

herry has nice colour and interesting texture. It has high physical and mechanical properties. The beautiful texture of cherry is second only to walnut.

Alder

Alder timber is soft and light. It has a homogeneous texture. The physical and mechanical properties of alder are similar to aspen.

Maple

Norway maple and white maples grow in the South-Western region of Ukraine. Maple timber is dense, hard and tough.

Elm

Elm has nice colour. There are often big warts formed on the trunk.
