中空玻璃 必須滿足兩個基本要求即節能、耐久性和密封壽命。如果一塊中空玻璃的節能效果很差，即使耐久性和密封壽命再長，也是一個低檔次的中空玻璃。反之，如果中空玻璃的節能性能好，但耐久性和密封壽命短，也不是人們所追求的。顯然，理想的中空玻璃應該同時具有最好的節能效果和最長的蜜蜂耐久性。

　　影響(xiang)中空(kong)(kong)玻璃節能(neng)(neng)性(xing)能(neng)(neng)的(de)主要因(yin)素有玻璃、間(jian)隔條（框）和氣(qi)體。在(zai)玻璃方(fang)面(mian)選擇有白玻或低輻射(she)玻璃；間(jian)隔條方(fang)面(mian)有冷邊(bian)（鋁(lv) 間(jian)隔條）或暖邊(bian)；氣(qi)體方(fang)面(mian)有空(kong)(kong)氣(qi)或惰性(xing)氣(qi)體如氬(ya)(ya)氣(qi)。在(zai)其他條件不變的(de)情況下(xia)，采用(yong)白玻、空(kong)(kong)氣(qi)和冷邊(bian)的(de)中空(kong)(kong)玻璃的(de)節能(neng)(neng)效果最(zui)差(cha)，而采用(yong)低輻射(she)玻璃、內(nei)充氬(ya)(ya)氣(qi)和暖邊(bian)的(de)中空(kong)(kong)玻璃節能(neng)(neng)效果最(zui)。

　　影響中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)的(de)(de)耐(nai)久性(xing)和密(mi)(mi)封(feng)壽(shou)命的(de)(de)主要因素有(you)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)密(mi)(mi)封(feng)膠(jiao)、密(mi)(mi)封(feng)結(jie)構、間(jian)(jian)隔條(tiao)(tiao)、干燥劑（分子篩）等等。事實(shi)已證(zheng)明，采(cai)用(yong)(yong)雙道(dao)密(mi)(mi)封(feng)、連續間(jian)(jian)隔條(tiao)(tiao)和3A分子篩的(de)(de)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)的(de)(de)密(mi)(mi)封(feng)壽(shou)命最長，而采(cai)用(yong)(yong)單道(dao)密(mi)(mi)封(feng)、四邊(bian)插角(jiao)鋁間(jian)(jian)隔條(tiao)(tiao)和4A分子篩的(de)(de)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)的(de)(de)密(mi)(mi)封(feng)壽(shou)命是較短的(de)(de)。北(bei)美中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)協會對中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)實(shi)際使用(yong)(yong)情(qing)況的(de)(de)20年(nian)跟(gen)蹤結(jie)果也證(zheng)實(shi)了這一點。另外(wai)，中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)加速老(lao)化(hua)實(shi)驗（PI檢測）結(jie)果表(biao)明，采(cai)用(yong)(yong)不同間(jian)(jian)隔條(tiao)(tiao)密(mi)(mi)封(feng)結(jie)果的(de)(de)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)的(de)(de)期望密(mi)(mi)封(feng)壽(shou)命相差是巨大的(de)(de)，短的(de)(de)僅僅為2個月，長的(de)(de)高達(da)100年(nian)以上。

　　在其他條(tiao)(tiao)件相(xiang)同的情況下，不同間(jian)隔條(tiao)(tiao)的采用(yong)直(zhi)接影響中(zhong)空玻璃(li)的節能(neng)性(xing)(xing)能(neng)和耐久(jiu)密(mi)(mi)封(feng)性(xing)(xing)。但(dan)在相(xiang)當長的一段時間(jian)內，人們普遍使(shi)用(yong)鋁間(jian)隔條(tiao)(tiao)（主要為(wei)四(si)邊插角）制(zhi)作中(zhong)空玻璃(li)，雖然密(mi)(mi)封(feng)壽命較長，但(dan)熱傳導(dao)(dao)性(xing)(xing)高，致(zhi)使(shi)節能(neng)效果差，直(zhi)接表現(xian)在中(zhong)空玻璃(li)邊部出(chu)現(xian)冷凝。而在20世紀70年代末，出(chu)現(xian)的復合膠條(tiao)(tiao)具有熱傳導(dao)(dao)性(xing)(xing)能(neng)低的特性(xing)(xing)，較使(shi)用(yong)鋁間(jian)隔條(tiao)(tiao)制(zhi)作中(zhong)空玻璃(li)節能(neng)有所(suo)改善，但(dan)不幸的是(shi)卻(que)同時減少了密(mi)(mi)封(feng)壽命。

　　這種不(bu)(bu)幸還表現在，在傳(chuan)統的(de)(de)(de)(de)(de)(de)(de)(de)思維(wei)框架里(li)，無(wu)論人們如何努力和(he)改進，改善(shan)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)的(de)(de)(de)(de)(de)(de)(de)(de)節(jie)能(neng)(neng)(neng)效果和(he)提高密封壽(shou)命耐(nai)(nai)(nai)久性(xing)，是不(bu)(bu)能(neng)(neng)(neng)兼得的(de)(de)(de)(de)(de)(de)(de)(de)。20世紀80年(nian)代末(mo)，兩名勇(yong)于進取富有(you)挑戰精神和(he)加拿(na)大科(ke)學家第(di)一次(ci)開發出(chu)同(tong)時解決中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)節(jie)能(neng)(neng)(neng)和(he)耐(nai)(nai)(nai)久性(xing)一對矛盾的(de)(de)(de)(de)(de)(de)(de)(de)方法，即超(chao)(chao)級(ji)間(jian)(jian)隔條(tiao)，在中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)領域引起了(le)一場革命。超(chao)(chao)級(ji)間(jian)(jian)隔條(tiao)是使(shi)用一種無(wu)任何金屬，內含3A分子(zi)篩的(de)(de)(de)(de)(de)(de)(de)(de)硅酮微(wei)孔結構(gou)材料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)連續間(jian)(jian)隔條(tiao)。其特點是導熱性(xing)能(neng)(neng)(neng)最(zui)(zui)小，可(ke)大幅度提高中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)四周邊(bian)(bian)緣的(de)(de)(de)(de)(de)(de)(de)(de)溫度，達到(dao)低輻射玻(bo)(bo)(bo)璃(li)節(jie)能(neng)(neng)(neng)效果的(de)(de)(de)(de)(de)(de)(de)(de)40%，大大減少玻(bo)(bo)(bo)璃(li)四周邊(bian)(bian)緣的(de)(de)(de)(de)(de)(de)(de)(de)冷凝程度。使(shi)用超(chao)(chao)級(ji)間(jian)(jian)隔條(tiao)制作(zuo)(zuo)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)采(cai)用逆向(xiang)的(de)(de)(de)(de)(de)(de)(de)(de)雙道密封方法，從而(er)使(shi)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)具有(you)了(le)卓(zhuo)越的(de)(de)(de)(de)(de)(de)(de)(de)耐(nai)(nai)(nai)久性(xing)和(he)密封壽(shou)命，可(ke)長達100年(nian)以上。據北美使(shi)用超(chao)(chao)級(ji)間(jian)(jian)隔條(tiao)制作(zuo)(zuo)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)的(de)(de)(de)(de)(de)(de)(de)(de)情況(kuang)來看，使(shi)用超(chao)(chao)級(ji)間(jian)(jian)隔條(tiao)制作(zuo)(zuo)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)不(bu)(bu)但節(jie)能(neng)(neng)(neng)性(xing)能(neng)(neng)(neng)佳，而(er)且由于其卓(zhuo)越的(de)(de)(de)(de)(de)(de)(de)(de)耐(nai)(nai)(nai)久性(xing)和(he)密封壽(shou)命而(er)最(zui)(zui)大程度地(di)減少了(le)售后服務（投訴）的(de)(de)(de)(de)(de)(de)(de)(de)問(wen)題。在北美，使(shi)用超(chao)(chao)級(ji)間(jian)(jian)隔條(tiao)制作(zuo)(zuo)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)的(de)(de)(de)(de)(de)(de)(de)(de)廠(chang)家對最(zui)(zui)終(zhong)用戶給(gei)出(chu)行業內最(zui)(zui)長的(de)(de)(de)(de)(de)(de)(de)(de)保(bao)質期(qi)20期(qi)的(de)(de)(de)(de)(de)(de)(de)(de)書(shu)面承(cheng)諾，而(er)其他(ta)廠(chang)家給(gei)出(chu)的(de)(de)(de)(de)(de)(de)(de)(de)保(bao)質期(qi)僅僅為5-15年(nian)不(bu)(bu)等。目前在眾多的(de)(de)(de)(de)(de)(de)(de)(de)間(jian)(jian)隔系統中(zhong)(zhong)，超(chao)(chao)級(ji)間(jian)(jian)隔條(tiao)是唯一能(neng)(neng)(neng)夠使(shi)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)璃(li)在使(shi)用期(qi)間(jian)(jian)長期(qi)保(bao)持最(zui)(zui)佳節(jie)能(neng)(neng)(neng)狀態(tai)的(de)(de)(de)(de)(de)(de)(de)(de)間(jian)(jian)隔條(tiao)。
