The walls are formed by uprights (elements of 150mm x 45mm), which are arranged, according to European requirements, from 40.64 cm to 40.64 cm. The uprights ensure stability and support for the platform (floor) of the next floor.
To better describe this method of prefabricating houses, it is best to start from the foundation up. First, the walls on the ground floor are installed, which are anchored in the existing concrete slab over the foundation. These walls represent the support for the floor above the ground floor, which is made of floor beams (220mm x 45mm), with OSB22mm cladding (groove and spring). Over this new floor, the upstairs walls are mounted.
This overlap of floors and walls of one level, forms the construction platform system on the wooden structure. This produces very resistant houses from a structural point of view, and reduces the risks related to the spread of the fire in height. Thus, short, light-walled structures are obtained, with low costs that are safer to build and install.
Their constructive style combines simple and modern solutions, which give them many advantages over brick or solid wood houses. The choice of this constructive style in Norway, Finland, USA or Canada is based on a very large volume of research on resistance, thermal comfort, health and environmental protection.
These wooden constructions are very well maintained over time and ensure all safety and comfort conditions. A wooden house adapts to all architectural and design styles.
The justification would be that:
- they are ecological houses
- they are houses resistant both in time and seismic
- they have perfect thermal insulation
- the duration of building such a house is very short;
