铝塑门窗特点
Characteristics of aluminum plastic doors and windows
塑钢门窗为多腔式结构，具有良好的隔热性能，其导热系数甚小，仅为钢材的l/357，铝材1/250，可见塑料门窗隔热、保温效果显著，尤其对具有暖气空调设备的现代建筑物更加适用。有关部门对此进行调查比较，即：使用塑钢门窗比使用木门窗的房间冬季室内温度可高4—5度；北方地区使用双层玻璃效果更佳。据建研院物理所测试，单玻钢，铝窗的传热系数为64W/M2K；单玻塑钢窗的传热系数是47W/M2K左右；普通双层玻璃的钢，铝窗的传热系数是3。7W/M2K左右；而双玻塑料钢窗传热系数约为2。5W/M2K。门窗占建筑外围护结构面积的30%，其散热量占49%，由此可知，塑钢窗有很好的节能效益
Plastic steel doors and windows are multi cavity structure with good thermal insulation performance, and their thermal conductivity is very small, which is only 1 / 357 of steel and 1 / 250 of aluminum. It can be seen that plastic doors and windows have remarkable heat insulation and heat preservation effect, especially for modern buildings with heating and air conditioning equipment. The relevant departments have made investigation and comparison, that is, the indoor temperature of rooms with plastic steel doors and windows can be 4-5 degrees higher than those with wooden doors and windows in winter; the effect of using double glass in northern areas is better. According to the test of Institute of physics, the heat transfer coefficient of single glass steel window is 64W / m2k; that of single glass plastic steel window is about 47w / m2k; that of ordinary double glass steel window is 3. The heat transfer coefficient of double glass plastic steel window is about 2. 5W/M2K。 Doors and windows account for 30% of the building envelope area, and its heat dissipation accounts for 49%. Therefore, plastic steel windows have good energy-saving benefits
