其實，合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)使用(yong)(yong)壽命的(de)(de)(de)長短主要與(yu)它生產(chan)時所添加的(de)(de)(de)原(yuan)材料有關。一(yi)(yi)般來說，合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)的(de)(de)(de)價格25-55元(yuan)不(bu)等。二十多元(yuan)一(yi)(yi)平(ping)方的(de)(de)(de)合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)，要么(me)(me)是劣質(zhi)的(de)(de)(de)ABS，要么(me)(me)是經(jing)過翻新(xin)的(de)(de)(de)ASA材料。用(yong)(yong)個5年左右，就會(hui)出現(xian)裂縫和漏水等一(yi)(yi)系列問題。俗話說：“一(yi)(yi)分錢(qian)一(yi)(yi)分貨(huo)，”說實在(zai)(zai)的(de)(de)(de)，質(zhi)量好的(de)(de)(de)合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)，質(zhi)保(bao)可達30年。 合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)上市以來，優質(zhi)的(de)(de)(de)合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)的(de)(de)(de)使用(yong)(yong)壽命一(yi)(yi)般在(zai)(zai)30年左右。而且，合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)在(zai)(zai)使用(yong)(yong)過程中不(bu)需要翻新(xin)和維(wei)護，省時省力又省錢(qian)。同時，合(he)成(cheng)(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)瓦(wa)(wa)還可綠色環保(bao)、經(jing)久(jiu)耐用(yong)(yong)、極具美觀裝(zhuang)飾性，廣泛應用(yong)(yong)于別墅、新(xin)農村建(jian)設、自(zi)建(jian)房、廠房、園林(lin)建(jian)筑(zhu)等屋(wu)頂的(de)(de)(de)防(fang)水裝(zhuang)飾。
