1、消聲性能：鍍鋅薄鋼板風管：無消聲性能，自身震動會產生聲音，必須加裝消聲器。無機玻璃鋼風管：無消聲性能，隔聲性能優于鍍鋅薄鋼板風管，必須加裝消聲器。復合玻纖板風管：其管壁是一種多孔性吸聲材料，可省去專用消聲器。纖維織物風管：其管壁為柔性纖維織物，不銹鋼通風管價格本身就是聲音的不良導體和吸收體，自身不會產生聲音，推薦不銹鋼通風管還可(ke)以一定程度(du)(du)上吸(xi)收設(she)備噪聲，隨(sui)著管(guan)(guan)道的延長，效(xiao)果更為明顯，可(ke)省(sheng)去專用消聲器(qi)。2、保(bao)溫(wen)性(xing)能：鍍鋅(xin)薄鋼板風管(guan)(guan)：導(dao)熱系數(shu)很大(為60.4 W/m?K)，無(wu)保(bao)溫(wen)性(xing)能，必(bi)須另外(wai)加(jia)包(bao)保(bao)溫(wen)層及保(bao)護(hu)層。無(wu)機玻璃鋼風管(guan)(guan)：導(dao)熱系數(shu)大(為0.5W/m?K)，無(wu)保(bao)溫(wen)性(xing)能。復合玻纖板風管(guan)(guan)：導(dao)熱系數(shu)小(平均溫(wen)度(du)(du)24℃時(shi)小于1W/m?K)，有一定保(bao)溫(wen)性(xing)能，不加(jia)裝保(bao)溫(wen)。
