常(chang)規來(lai)說，用(yong)戶在選擇一種(zhong)建筑(zhu)保溫材(cai)料(liao)的(de)(de)時候 ，一般會(hui)先去了解下它(ta)(ta)的(de)(de)導(dao)熱系(xi)數(shu)(shu)，導(dao)熱系(xi)數(shu)(shu)越小，相對保溫性能就(jiu)越好，單單這(zhe)樣(yang)看確實(shi)沒錯，但當(dang)保溫材(cai)料(liao)應(ying)用(yong)到(dao)實(shi)際的(de)(de)工程(cheng)項目中(zhong)，升(sheng)級為整個保溫系(xi)統的(de)(de)時候，它(ta)(ta)的(de)(de)導(dao)熱系(xi)數(shu)(shu)就(jiu)不那么簡(jian)單了。事(shi)實(shi)證明(ming)，保溫材(cai)料(liao)的(de)(de)應(ying)用(yong)技術水平、水氣環境與(yu)溫度條(tiao)件、冷熱橋、設計構造(zao)、施工工藝(yi)等都會(hui)影響到(dao)系(xi)統的(de)(de)導(dao)熱系(xi)數(shu)(shu)。
