Aluminium foil yometse kuri fiberglass yimyenda ikozwe mubitambaro bya fiberglass yometse kuri aluminiyumu cyangwa firime kuruhande rumwe. Irashobora kwihanganira ubushyuhe bukabije, kandi ifite ubuso bunoze, imbaraga nyinshi, urumuri rwiza rumurika, izirinda kashe, izirinda gaze hamwe n’amazi.
Ikirahuri cya fibre kaseti ikozwe mubushyuhe bwo hejuru hamwe na fibre ikomeye yibirahure, bitunganywa muburyo budasanzwe. Ifite ibiranga ubushyuhe bwo hejuru, kurwanya ubushyuhe, kubika, kubika umuriro, kurwanya ruswa, kurwanya gusaza, kwihuta kwikirere, imbaraga nyinshi no kugaragara neza.
Glasflex ikorwa muguhuza fibre yibirahuri byinshi hamwe nu mfuruka yihariye yo kuzenguruka binyuze mumuzingi. Bene ubwo buryo bwimyenda idafite ubudodo kandi burashobora kwagurwa kugirango bihuze nurwego runini. Ukurikije inguni (muri rusange hagati ya 30 ° na 60 °), ubwinshi bwibintu hamwe numubare wudodo inyubako zitandukanye zirashobora kuboneka.
