建筑物外门窗的热量损耗有三个途径：一，通过铝合金型材的热量传导损失；第二，通过玻璃的辐射热量损失；第三，通过门窗缝隙的空气对流热量损失。因此，保温节能铝塑门窗的制作也要从这三个方面考虑。
The heat loss of building doors and windows are three ways: first, through the heat conduction loss of aluminum alloy profile; second, through the glass of radiation heat loss; third, through the air convection heat loss in the gap of doors and windows. Therefore, making thermal insulation and energy-saving aluminum doors and windows should also be considered from the three aspects of.
1、铝合金型材铝合金材料是热的良导体，热导率多数比较高。要制成保温隔热玻璃，要选择有隔热断桥处理的型材，即隔断型材热传导的通路，以达到保温隔热的目的。

1 aluminum alloy profiles, aluminum alloy material is a good conductor of heat, thermal conductivity of most high. Be made of insulating glass, to choose a profile bridge insulation treatment, i.e. partition path profiles of heat conduction, so as to achieve the purpose of heat insulation.
2、玻璃保温隔热门窗需要采用中空玻璃，因为中空玻璃之间的空腔内充满干燥、静止的空气，使热导率大大降低，因此中空玻璃具有优良的隔热、隔声和抗霜凝、结露性能，常用的中空玻璃的玻璃厚度5~6mm，常见的空腔厚度有9mm、12mm。
2, glass insulation doors and windows with insulating glass, hollow glass because the cavity between the filled with dry, static air, the thermal conductivity is reduced greatly, so the hollow glass has excellent heat insulation, sound insulation and frost and condensation performance, the thickness of the glass 5~6mm glass commonly used, cavity thickness of common 9mm, 12mm.
3、密封材料保温隔热门窗用的密封胶应选用耐候胶，密封胶条应选用抗臭氧腐蚀性能及抗紫外线老化性能优良的氯丁橡胶制品，门窗扇开启重合部分要设置三道以上密封胶条。
3, the sealing material thermal insulation doors and windows with sealant should be weather resistant adhesive sealant should be used in the ozone resistance corrosion resistance and anti ultraviolet aging properties of chloroprene rubber, doors and windows open to set up three or more overlapping part of sealing strip.
