For production of a glued bar according to operating normative documentation qualitative coniferous wood should be used. The stock of such wood is almost exhausted. Therefore the task of resource-saving while producing glued bars comes to the fore. Two ways of increasing the efficiency of building constructions made of wood are offered in the article. The essence of the first way consists in the use of thin truncated timber as outside lamels. Such timber is produced of knot-free zones of trunks. Thus resistance to heat transfer of the offered and traditional bar differs slightly. Economic calculations showed lowering of the expenditure of wood by production of a glued bar with lamels of different thickness by 7 % that leads to more rational use of all wood of a trunk. The second way to increase of efficiency of the guarding constructions consists in the use of a heater in a multi-layer glued bar. The basis of this heater is natural material of lean production waste - shove. In its anatomic and chemical structure shove is similar to wood, it is an ecologically safe and cheap heater. Therefore in the offered glued bar three lamels of wood of coniferous breeds interstratified with two shove plates 20 millimeters thick. The coefficient of heat conduction of such bar practically doesn’t differ from coefficient of heat conduction of a traditional five-layer glued bar. Thus essential reduction in cost of materials for its production almost by 50 % makes such a bar economically attractive is watched.
