Ukukhetha iglasi yokwakha efanelekileyo kubalulekile kwiprojekthi eyimpumelelo. Ukufumana izigqibo ezizezinye kuvavanyo, ukhetho kunye nokucaciswa kweglasi yokwakha, iVitro Architectural Glass (eyayisakuba yiglasi yePPG) icebisa ukuba uqhelane nepropathi kunye nezibonelelo zeentlobo ezine zeglasi eziqhelekileyo: iglasi edityanisiweyo, iglasi ecacileyo, iphantsi- iglasi yentsimbi kunye neglasi enombala.

Iglasi ePhantsi ye-E
Iglasi yombono egutyungelweyo yaqala ukwaziswa ngeminyaka yoo-1960 ukunciphisa ubushushu elangeni kunye nokwandisa iindlela zokukhetha ubuhle. I-emissivity ephantsi okanye i "low-e" yokwaleka yenziwe nge-metallic oxides. Zibonisa nawaphi na amandla amaza ombane aphuma kwiglasi, ukunciphisa ubushushu obudlula kuyo.

Izambatho ezisezantsi-e zithintela inani le-ultraviolet kunye nokukhanya kwe-infrared okungadlula kwiglasi ngaphandle kokubeka esichengeni isibane sokukhanya okubonakalayo okuhanjisiweyo. Xa ubushushu okanye amandla okukhanya etsalwa ngegilasi, ayasuswa ngokuhamba komoya okanye ahlengahlengiswe ngumphezulu weglasi.

Izizathu zokucacisa iiglasi eziDibeneyo ze-E
Ilungele imozulu elawulwa kukufudumeza, iglasi ethe nkqo esezantsi ivumela amanye amandla elanga e-infrared ukuba adlule kuwo. Oku kunceda ukufudumeza isakhiwo, ngelixa kusabonisa ubushushu bamaza obushushu bangaphakathi ngaphakathi.

Ilungele iimeko zemozulu ezipholileyo, ulawulo lwelanga zitshixe iglasi iibhloko zelanga kwaye zibonelela ngokufudumeza kobushushu. Oku kugcina umoya opholileyo ngaphakathi kunye nomoya oshushu ngaphandle. Zininzi izibonelelo zeglasi ezombathisiweyo ezonga umbane, kubandakanya ukwanda kokuhlala kunye nemveliso, ukulawulwa kwemini kunye nolawulo lwelitha. Iiglasi ezifakwe i-low-e zivumela umnini wesakhiwo ukuba aphathe ngcono ukusetyenziswa kwamandla ngokunciphisa ukuthembela ekufudumaleni nasekupholiseni, okukhokelela ekongeni ixesha elide.

Coca iglasi
Iglasi ecacileyo lolona hlobo lweglasi lusetyenziswa ngokuxhaphakileyo kwaye iyafumaneka kubukhulu obahlukeneyo. Ngokwesiqhelo inokuhambisa okuphezulu okuphezulu kokukhanya kunye nokungathathi hlangothi kombala kunye nokucaca, nangona i-hue yayo eluhlaza iyaqina njengoko ubukhulu bonyuka. Umbala kunye nokusebenza kweglasi ecacileyo kuyahluka ngokwenziwa ngumenzi ngenxa yokunqongophala kombala osesikweni okanye inkqubo yokusebenza echazwe yi-ASTM yaMazwe ngaMazwe.

Izizathu zokuCacisa iGlasi ecacileyo
Iglasi ecacileyo icacisiwe gabalala ngenxa yexabiso layo eliphantsi ngenxa yokusebenzisa kwayo izinto ezirisayikilishwe. Yisiqwenga somgangatho ophezulu sokusebenza okuphezulu kwe-e-e-coating nakwiindidi ezahlukeneyo, ukusuka kwi-2.5 millimeters ukuya kwi-19 millimeters. Yisiqwenga esihle sokusebenza okuphezulu ukutyabeka okungaphantsi.

Iindidi zezicelo zeglasi ecacileyo zibandakanya iiyunithi zeglasi zokugquma (ii-IGU) kunye neefestile, kunye neengcango, izipili, iglasi yokhuseleko elaminethiweyo, ngaphakathi, ngaphakathi kunye neesahlulelo.

Iglasi eNombala
Yenziwe ngokudibanisa indibaniselwano encinci kwiglasi ngexesha lokuvelisa, iglasi enombala ibonelela ngemibala efudumeleyo okanye yepeyinti epholileyo, enje ngombala oluhlaza okwesibhakabhaka, ubhedu oluhlaza kunye grey. Ikwabonisa uluhlu olubanzi lweetintshi ukusuka ekukhanyeni ukuya phakathi ukuya ebumnyameni ngaphandle kokuchaphazela iipropathi ezisisiseko zeglasi, nangona zichaphazela ubushushu kunye nokuhambisa ukukhanya kumanqanaba ahlukeneyo. Ukongeza, iglasi enombala inokulaminishwa, ubushushu okanye yomelezwe ubushushu ukwanelisa amandla okanye ukhuseleko. Okufana neglasi ecacileyo, umbala kunye nokusebenza kweglasi enombala kuyahluka ngokwenziwa ngumvelisi kuba akukho mbala we-ASTM okanye imigaqo yokusebenza yeglasi enombala ekhoyo.

Izizathu zokucacisa iiglasi eziHoliweyo
Iglasi enombala ilungele nayiphi na iprojekthi enokuxhamla kumbala owongeziweyo ohambelana nayo yonke uyilo lokwakha kunye neempawu zesiza. Iglasi epeyintiweyo ikwaluncedo ekunciphiseni ukuqaqamba kunye nokunciphisa ubushushu belanga xa isetyenziswa ngokudibeneyo kunye neepawoti ezisezantsi.

Ezinye zezinto ezenziwe ngeglasi enombala zibandakanya ii-IGUs, ii-facade, ukhuseleko lweglasi, iglasi ye-spandrel kunye neglasi enye ye-lite-monolithic. Iiglasi ezingamacwecwe zinokuveliswa ngee-e-coating ezongeziweyo zokwenza umsebenzi ongezelelweyo okanye wolawulo lwelanga. Iglasi enamabala nayo inokulaminishwa, yomelele okanye yomelezwe ubushushu ukwanelisa iimfuno zamandla okanye zokhuseleko.

Iglasi yentsimbi ephantsi
Iglasi yentsimbi ephantsi yenziwa ngolwakhiwo olunika ukuphakama kwamanqanaba okucaca kunye nokungafihli xa kuthelekiswa neglasi yemveli ecacileyo. Kuba akukho lucaciso lwe-ASTM lweglasi yentsimbi esezantsi, amanqanaba okucaca anokuhluka ngokubanzi ngokusekwe kwindlela ezenziwa ngayo kunye namanqanaba esinyithi afumaneka kwiifomula zawo.

Izizathu zokuchaza iglasi yentsimbi ephantsi
Iglasi yesinyithi esisezantsi icacisiwe kuba inepesenti nje yomxholo wentsimbi yeglasi eqhelekileyo, ivumela ukuba idlulise ipesenti yokukhanya engama-91 xa kuthelekiswa neepesenti ezingama-83 zeglasi eqhelekileyo, ngaphandle kwempembelelo yokuluhlaza enxulunyaniswa neepaneli zeglasi ezicacileyo. Iglasi yentsimbi ephantsi ikwacacisa inqanaba eliphezulu lokucaca kunye nokuthembeka kombala.

Iglasi yentsimbi ephantsi ilungele ukhuseleko kunye ne-glazing yokhuseleko, imiqobo yokhuseleko, iifestile zokhuselo kunye neengcango. Iglasi yentsimbi ephantsi ikwacacisiwe kwizinto zangaphakathi ezinje nge-spiderwalls, i-balustrades, iitanki zentlanzi, iglasi yokuhombisa, iishelfu, iitafile, i-backsplashes kunye neengcango. Ukusetyenziswa kwangaphandle kubandakanya ukuqaqanjelwa kombono, isibhakabhaka, ukungena kunye neefestile.
