Udonga lwamakhethini esakhiwo, iingcango kunye neefestile zenziwe ngokukodwa ngeglasi eyomileyo ye-laminated, ehlangabezana nezi mfuno zingentla. I-organic glue layer material ikakhulu yifilimu ye-PVB, kwaye ifilimu ye-EVA ayifane isetyenziswe. Ifilimu entsha ye-SGP ephuhliswe kwiminyaka yakutshanje inomsebenzi ogqwesileyo. Iglasi elaminethiweyo ye-SGP inethemba elibanzi nelilungileyo lokusetyenziswa kwizibane zeglasi, iifestile zeglasi zangaphandle kunye neendonga zekhethini. Ifilimu ye-SGP yiglasi elaminated ionomer interlayer. I-SGP ionomer interlayer eveliswe yiDuPont e-United States inomsebenzi ogqwesileyo, amandla okukrazula amaxesha angama-5 kwifilimu ye-PVB eqhelekileyo, kwaye ubunzima buphindwe ngama-30-100 kwifilimu ye-PVB.
