I-E-glass fibre yarn twist yizinto ezivikelayo zikagesi, izindwangu zezimboni zikagesi nezinye izindwangu zokusetshenziswa kwezimboni zezinto ezingavuthiwe, ezisebenza ocingweni lokuluka nokuhlanganisa ikhebula, i-casing, i-fuse yezimayini, zonke izinhlobo zezinto zikagesi zokuvikela impahla kagesi. Ukusebenza okuyinhloko ukuqina kokuqina kokuqina kwentambo, ukumelana nokugqokwa, nocingo lwezinwele oluncane, amandla aqinile aqinile, ukufakwa kukagesi, ukumelana nokugqwala, ukumelana nokushisa okuphezulu, ukugqwala okuhle kwamakhemikhali. Umugqa wokulinganisa usebenzisa i-ejenti yokuhlanganisa esekelwe isitashi kanye nokusetshenziswa kosayizi ogqanyiswe ngokugcwele.
Izintambo ze-Fiberglass zihlanganisa inombolo echaziwe ye-E-Glass filaments enobubanzi obuthile obungajwayelekile, ehlanganiswe ndawonye ukuze kwakheke umucu. Isakhiwo sentambo silungisiwe futhi sivikelwe usayizi nokusonteka okuncane, ngokuvamile ku-Z-direction.
