New composite wooden beam for low-rise construction

The article discusses three main aspects of wooden low-rise housing construction that is environmental, economic and aesthetic ones. A wooden house is an environmentally friendly and healthy housing. Wooden houses usually cost less than stone or brick ones and require less energy for heating. Wooden houses can have a unique and attractive appearance thanks to various methods of finishing and decoration. The paper analyzes the new requirements for thermal engineering of enclosing structures and focuses on a new composite building material “Composite wooden beams” developed for low-rise housing construction. It presents the results of theoretical calculations and comparisons of heat transfer resistance for laminated timber and composite wooden beams, as well as the vapor permeability resistance of the new building material.
