Ulusi wa fiberglass umapangidwa ndi mipira yagalasi kapena magalasi otayira pogwiritsa ntchito kusungunuka kwa kutentha kwambiri, kukoka waya, kupotoza, kuluka ndi njira zina. Ulusi wa fiberglass umagwiritsidwa ntchito makamaka ngati zinthu zamagetsi zotetezera kutentha, zinthu zosefera zamafakitale, zoletsa dzimbiri, zosanyowa, zoteteza kutentha, zoteteza mawu, zoyamwa kugunda kwa mtima. Ungagwiritsidwenso ntchito ngati zinthu zolimbitsa kupanga zinthu zapulasitiki zolimbitsa fiberglass monga pulasitiki yolimbitsa kapena gypsum yolimbitsa. Kupaka fiberglass ndi zinthu zachilengedwe kungathandize kusinthasintha kwawo ndipo kungagwiritsidwe ntchito popanga nsalu zopaka, zophimba mawindo, zophimba makoma, nsalu zophimba, zovala zoteteza ndi zipangizo zamagetsi ndi zotetezera mawu.

Ulusi wa fiberglass monga chinthu cholimbikitsira fiberglass uli ndi makhalidwe otsatirawa, makhalidwe awa amapangitsa kuti kugwiritsa ntchito fiberglass kukhale kwakukulu kwambiri kuposa mitundu ina ya ulusi, ndipo liwiro la chitukuko nalonso lili patsogolo kwambiri kuposa makhalidwe ake omwe alembedwa motere: (1) mphamvu yayikulu yolimba, kutalika pang'ono (3%). (2) Kuchuluka kwa elasticity komanso kulimba bwino. (3) Kuchuluka kwa elasticity mkati mwa malire a elasticity ndi kwakukulu ndipo mphamvu yolimba ndi yayikulu, kotero kuyamwa kwa mphamvu yogwira ntchito ndi kwakukulu. (4) Ndi ulusi wosapangidwa ndi zinthu zachilengedwe, womwe sungayake ndipo uli ndi kukana kwabwino kwa mankhwala. (5) Kuyamwa madzi pang'ono. (6) Kukhazikika kwa mawonekedwe ndi kukana kutentha zonse ndi zabwino. (7) Ili ndi kuthekera kokonza bwino ndipo ingapangidwe m'njira zosiyanasiyana monga ulusi, mitolo, ma felts, ndi nsalu zolukidwa. (8) Yowonekera bwino komanso yololedwa kuwala. (9) Kupanga chothandizira chochizira pamwamba chomwe chimamatira bwino ku resin kwatha. (10) Mtengo wake ndi wotsika mtengo. (11) Sikophweka kuyaka ndipo kumatha kusungunuka kukhala mikanda yagalasi kutentha kwambiri.
Ulusi wa fiberglass umagawidwa m'magawo awiri: nsalu yozungulira, yozungulira (nsalu yoyang'aniridwa), mphasa ya fiberglass, ulusi wodulidwa ndi ulusi wopukutidwa, nsalu ya fiberglass, chowonjezera chowonjezera cha fiberglass, mphasa yonyowa ya fiberglass.
Ngakhale kuti ulusi wa fiberglass wakhala ukugwiritsidwa ntchito pa ntchito yomanga kwa zaka zoposa 20 zokha, bola ngati pali ma eyapoti, malo ochitira masewera olimbitsa thupi, malo ogulitsira zinthu zambiri, malo osangalalira, malo oimika magalimoto, malo ochitira zisudzo ndi nyumba zina, makatani a fiberglass okhala ndi PE amagwiritsidwa ntchito. Popanga mahema, nsalu yophimba fiberglass yokhala ndi PE imagwiritsidwa ntchito ngati denga, ndipo kuwala kwa dzuwa kumatha kudutsa padenga kukhala gwero lofewa la kuwala kwachilengedwe. Chifukwa chogwiritsa ntchito zophimba zenera za fiberglass zokhala ndi PE, ubwino ndi moyo wa ntchito ya nyumbayo zidzasintha kwambiri.
