断桥铝是指隔断冷热桥，因为铝合金是金属，导热比较快，所以室内外温 度相差很多时，铝合金就成了为热量传递的“桥”了，断桥就是将铝合金从中间断开，采用硬塑与两边的铝合金相连，而塑料导热慢，这样热量就不容易传递了，所以叫断桥铝合金。  断桥铝采用隔热铝型材和中空玻璃，仿欧式结构，外形美观，具有节能、隔音、防噪、防尘、防水功能。橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子 这类门窗的热传导系数K值为3W/m2·K以下，比普通门窗热量散失减少一半，降低取暖费用30%左右，隔声量达30分贝以上，水密性、气密性良好，均达国家A1类窗标准

The aluminum partition refers to cold bridges, because Aluminum Alloy is metal, heat faster, so the indoor and outdoor temperature difference, Aluminum Alloy became for the heat transfer of "bridge", the bridge is Aluminum Alloy disconnected from the middle of the hard plastic is connected with the Aluminum Alloy on both sides, and the plastic slow heat conduction so, the heat is not easy to transfer, so it is called the Aluminum Alloy. The broken bridge aluminum adopts insulated aluminum profile and hollow glass, imitating European structure, with beautiful appearance, and has the functions of energy saving, sound insulation, noise proof, dustproof and waterproof. The thermal conductivity K of such doors and windows is 3W/m2. K, less than half of the heat loss of ordinary doors and windows, and the heating cost is reduced by about 30%. The sound insulation volume is above 30 dB, and the water tightness and tightness are all good, which all reach the national A1 window standard.
