CLT WOODEN HOUSES
LOW ENERGY AND PASSIVE WOODEN HOUSES
CLT-based wooden construction is a type of prefabricated construction which means the walls are entirely completed in the production process. They are transported to and assembled at the chosen location of the facility. Therefore, buildings made of prefabricated CLT are constructed in a quick (construction in 2-3 days), quiet and clean manner.
Each individual CLT panel consists of several layers of spruce boards with a thickness of 20 to 40 cm. The walls are bonded alternatively at right angles to each other to prevent subsidence. The ap-plied adhesive is harmless to our health.
The walls are available up to a thickness of 0.32 m, with a maximum length of 16 m and a maximum height of 2.95 m. When constructing larger walls, multiple CLT walls can be connected together without affecting mechanical and thermal properties. Consequently, CLT technology can be used not only to build residential houses, but also apartment buildings or health, educational, and busi-ness facilities. CLT panels can be used for outer and inner walls, as mid floor or roof panels. A house can be completely built from solid wood walls.
HEALTH IN WOODEN HOUSES
ADHESIVES USED FOR CLT
We got many questions addressed regarding adhesives used in CLT houses lately. Adhesives used for bonding wooden lamels into CLT walls are from PUR group of adhesives. PUR stands for a one component polyurethane adhesive. This formaldehyde free adhesive represent no risk and danger to our health. Having in mind, that thin layers of adhesives represent less than 1% of entire wall mass, their effect is easily negligible.
