Ezona zakhiwo zinemincili ezakhiweyo namhlanje zezongamandla, zihambelana nokusingqongileyo kwaye ziluhlaza ngokucokisekileyo.I-Insulating Glass Unit (ebizwa ngokuba yi-IGU okanye i-IG unit) kunye ne-Low-E coating sele ibe yinto yokuqala yokukhetha izakhiwo zanamhlanje.Ayisekuko nje ukuzikhusela kwisiphango, kodwa okona kubaluleke ngakumbi ukudibanisa imisebenzi emininzi yokugqunywa kwe-thermal, ukonga amandla, ubugcisa, ukuzola nokhuseleko.Ibonelela ngendawo yokuhlala etofotofo apho abantu banokonwabela amaxesha amane onyaka, ukusebenza kakuhle kwamandla, ukuhambelana kokusingqongileyo kunye nokuqaqamba.
I-Jinjing inikezela ngolungelelwaniso oluninzi lweeyunithi zeglasi ezikhuselayo, iinketho ezininzi ze-IGU.Iiyunithi zokugquma nazo zinamathuba amaninzi okuhombisa inkangeleko kunye nokusebenza kwisakhiwo sakho, kubandakanya isikrini sesilika kunye noshicilelo lwedijithali olunemibala etyebileyo, iinotshi kunye nemingxunya ukuba kuyafuneka, ukuzaliswa kwe-argon, igophe kunye neyunithi ye-IGU emile.
