Izakhiwo ezijabulisa kakhulu ezakhiwe namuhla ezonga amandla, aziyilungele imvelo futhi ziluhlaza ngokuphelele.Insulating Glass Unit (evame ukubizwa ngokuthi i-IGU noma iyunithi ye-IG) ene-Low-E coating isivele ibe ukukhetha kokuqala kwezakhiwo zesimanje.Akusekho nje ukuvikela isiphepho, kodwa okubaluleke kakhulu ukuhlanganisa imisebenzi eminingi yokushisa okushisayo, ukonga amandla, ubuciko, ukuthula nokuphepha.Ihlinzeka ngendawo yokuhlala enethezekile lapho abantu bengajabulela khona izinkathi ezine zonyaka, ukonga amandla, ukuvumelana kwemvelo nokukhanya.
I-Jinjing inikeza ukucushwa okuningi kwamayunithi engilazi avikelayo, izinketho eziningi ze-IGU.Amayunithi avikelayo aphinde abe namathuba amaningi obuhle okuthuthukisa ukubukeka nokusebenza kwesakhiwo sakho, okuhlanganisa isikrini sikasilika nokuphrinta kwedijithali okunemibala ecebile, amanotshi nezimbobo uma kudingeka, ukugcwaliswa kwe-argon, iyunithi ye-IGU egobile futhi enomumo.
