Houses built in a system of prefabricated walls and elements with a wooden frame are currently the most popular technology for building houses. The production of walls and elements of houses with a wooden frame in prefabricated technology in the plant is organized in such a way that the components of the house (external walls, partitions, ceilings, roof panels, truss and other elements) are manufactured in factory conditions. The house is assembled on the construction site efficiently and quickly like (example Lego blocks) This system is controlled at every stage of production and prevents the occurrence of any construction or technical errors that could have a negative impact on the assembly of the building.
