Lub tsev ntaub thaiv phab ntsa, qhov rooj thiab qhov rais yog tsim los ntawm cov iav laminated qhuav, uas ua tau raws li cov lus qhia saum toj no. Cov khoom siv kua nplaum organic feem ntau yog PVB zaj duab xis, thiab EVA zaj duab xis tsis tshua siv. SGP zaj duab xis tshiab tsim nyob rau xyoo tas los no muaj kev ua tau zoo heev. SGP laminated iav muaj qhov dav thiab zoo daim ntawv thov kev cia siab nyob rau hauv iav skylights, iav sab nrauv qhov rais thiab kab hlau rhuav phab ntsa. SGP zaj duab xis yog laminated iav ionomer interlayer. SGP ionomer interlayer tsim los ntawm DuPont hauv Tebchaws Meskas muaj kev ua tau zoo, lub zog tsim kua muag yog 5 npaug ntawm cov yeeb yaj kiab PVB zoo tib yam, thiab qhov nyuaj yog 30-100 npaug ntawm PVB zaj duab xis.
