Nrog rau txoj kev loj hlob ntawm architectural tsim, tib neeg muaj kev xav tau ntau dua rau kev pom kev pom tseeb thiab qhov tshwj xeeb zoo nkauj ntawm cov tsev. Qhov kev faib ua feem ntawm cov iav nyob rau hauv cov txheej txheem tiv thaiv sab nrauv ntawm cov tsev kuj nce. Raws li cov khoom siv hauv tsev, kev nyab xeeb ntawm iav kuj tau nce nqi. Tempered iav siv nyob rau hauv vaj tse belongs rau lub tsev ruaj ntseg iav. Tempered iav yog tsim los ntawm ntab iav raws li daim ntawv qub, uas yog cua sov thiab txias dua. Piv nrog ntab iav thiab cov iav tiaj tiaj zoo tib yam, nws txoj kev nyab xeeb kev ua tau zoo tau zoo dua qub. Tempered iav tau txhim kho nws qhov kev tiv thaiv sab nraud, uas yog 3-5 npaug ntawm cov iav ntab thiab cov iav zoo tib yam. Thaum cov iav tempered tawg los ntawm kev cuam tshuam sab nraud, nws yuav tawg mus rau hauv cov khoom me me (lub teb chaws tus qauv rau cov iav tempered xav tau ntau tshaj 40 cov khoom nyob rau hauv thaj tsam ntawm 50mm × 50mm). Thaum lub iav tawg tawg thiab ntog los ntawm qhov chaw siab, nws yuav tsim lub iav los nag, uas yuav tsis ua rau tib neeg lub cev raug mob.
Thaum xaiv lub tsev ruaj ntseg iav, cov ntsiab lus hauv qab no yuav tsum tau sau tseg: 1. Lub tsev tempered iav belongs rau lub teb chaws CCC cov khoom yuav tsum tau ntawv pov thawj, thiab cov khoom ntawm cov tuam txhab muaj ntawv pov thawj yog affixed nrog 3C certification mark. 2. Txheeb xyuas qhov zoo ntawm cov iav. Cov iav nrog cov npoo tawg, khawb, thiab qhov tsis xws yuav ua rau tawg thiab txo lub zog thaum siv. 3. Ntsuas seb lub iav puas khoov ntau dhau, raws li cov iav khoov ntau dhau ua rau muaj kev ntxhov siab thaum lub sij hawm lossis tom qab kev teeb tsa, ua rau muaj kev tawg. Kev tshuaj xyuas qhov zoo ntawm iav edging, tempered iav nrog siab edging zoo muaj lub zog siab thiab qis tus kheej tawg.
