Imishini yokucubungula ingilazi ye-CBS ifaka phakathi umugqa wokukhiqiza ingilazi ovikela ukushisa, umshini wokuwasha ingilazi ovundlile noqondile, umshini wokugoqa ingilazi kanye netafula lokusika ingilazi njll. Ukuze kuhlangatshezwane nezidingo zabakhiqizi beyunithi yengilazi evikela ukushisa (i-IGU), i-CBS itshala imali njalo ekucwaningeni nasekuthuthukiseni imishini emisha. Imishini yethu yengilazi evikela ukushisa isetshenziswa kabanzi ekukhiqizeni ingilazi yensimbi evamile (i-aluminium spacer, i-stainless spacer, njll.) kanye ne-non-metal warm edge spacer (njenge-super spacer, i-Dual Seal, njll.).
