建筑门窗经历了几次变革,从木窗到钢窗、铝合金窗、塑钢窗再到现在断桥铝窗,门窗的更新换代不仅是市场所需,更反映了整个门窗行业的提升。
塑钢窗的优点是管理运营成本低,价格有优势,并且耐腐蚀。被引入中国市场后,其核心的添加剂和配方仍掌握在国外企业手中,价格较高,随着国内产业竞争的不断加剧,一些企业为了降低成本,开始减少甚至取消了各种重要添加剂,减小型材壁厚,开发推拉窗等五金成本低的新产品。这种降低标准、降低配置的现象,最后竟演化成为全行业不可逆转的恶果—塑钢窗的缺点便集中暴露出来,并成为全行业普遍存在的现象,比如黄变,日久会变脆,并引发了多起安全事故。1999年建设部发文,高层建筑禁止使用塑钢窗,塑钢门窗市场迅速萎靡。塑钢门窗品质的下降,将其推进死巷,于是铝合金窗回光返照。
经历了三次变革,门窗行业对铝合金和塑钢有了更为深刻的认识。为了解决隔热的问题,我国的科学家发明了断桥铝合金。原理是利用PA66尼龙将室内外两层铝合金既隔开又紧密连接成一个整体,构成一种新的隔热型的铝型材。但在使用过程中,出现了很多问题,后来又从德国,法国和比利时进口强力尼龙等材料。
断桥铝窗隔热性能的革命性提高,从一定程度上解决了铝合金传导散热快、不符合节能要求的致命问题,于是开始被市场推崇。
