一、概述塑料门窗作为一种新型建筑节能产品,具有保温、隔音、节能、外型美观等优点,近年来塑料门窗的应用越来越普遍。然而因其型材结构及加工工艺、安装工艺等特点,塑料门窗的雨水渗漏现象时有出现。特别是对于沿海地区,多热带风暴和台风,风压较大,塑料门窗的雨水渗漏现象更加突出,占到门窗质量投诉的70%以上。据工程统计,塑料门窗渗水情况如下:门窗周边渗水占40%,门窗拼樘渗水占30%,门窗压条、扇渗水占20%,墙体渗水占10%。 First, an overview Plastic doors and windows as a new type of building energy-saving products, with insulation, noise, energy saving, good looks and other advantages, in recent years the application of plastic doors and windows more and more common. However, due to its profile structure and processing technology, installation process and other characteristics, plastic doors and windows of the phenomenon of leakage from time to time there. Especially for the coastal areas, tropical cyclones and typhoons, the wind pressure is larger and the leakage of plastic doors and windows is more prominent, accounting for more than 70% of the quality complaints of doors and windows. According to the project statistics, seepage of plastic doors and windows are as follows: seepage around the doors and windows accounted for 40%, 30% of seepage fight spell, windows and doors, fan seepage 20%, wall seepage 10%.
