门窗与建筑节能

"十一五"期间,国家明确提出了建筑节能必须达到50%,门窗是建筑的重要组成部分,耗能大约占建筑能耗的40%以上,是墙体热损失的5～6倍.因此,门窗节能势在必行.通过门窗传热原理,从窗型、玻璃、窗用型材、五金配件、密封条、制作与安装等各个环节阐述了对节能门窗的影响.只有做到科学设计,合理选材,精心制作,规范安装,才能成为真正的节能门窗.

Energy-Saving with Regard to Doors and Windows

During"11th five-year plan" period, the state puts forward clearly that energy-saving of architecture must reach 50%. The doors and windows are the important part of architecture, their energy consumption accounts for more than 40% of that of architecture,which is five to six times as much as the heat loss of wall. Therefore, energy-saving of the doors and windows is bound to be carried out. Based on the principle of heat conduction of the doors and windows, the effects on energy-saving doors and windows were described, which includes window pattern, glass, window section bar, hardware fittings, sealed strip, manufacture installation and etc.. Only through the scientific design, reasonable selection of material, elaborate manufacture and standardized installation, can we make the real doors and windows of energy-saving.
