Fiberglass yubatswe bakoreshwa kubuso bwombi no gusubiza inyuma ibyuma byumye (bizwi kandi nka gypsum board). Bongera ubukana, kuramba, kwihanganira ibirimi, hamwe no kurwanya ububi bwibi bibaho bya gypsumu, bigatuma bikwiranye nuburyo butandukanye bwo kubaka.

Kurugero, ikibaho cya gypsum irwanya flame isanga ikoreshwa muburyo busaba umutekano w’umuriro nk’ibigo byubucuruzi, ibigo nderabuzima, ibibuga byindege, cyangwa icumbi. Mugihe c'umuriro, fiberglass irashobora gukingira akuma, igatanga umwanya winyongera mugihe cyo kwimuka.

Byongeye kandi, matiku ya fiberglass yera ya GRECHO yihariye kandi ashyirwa mubikorwa cyane muburyo bwiza bwo kubaka. Bahuye nibisabwa byo gushushanya ikibaho cya gypsumu mumirenge itandukanye, batanga ubwiza bwubwiza bwiza nibikorwa byiza.
