Nsalu yosefera ya fiberglass yomwe imapangidwa imakhala ndi mphamvu yochotsa fumbi yoposa 99.9% pambuyo popaka filimu, zomwe zimatha kutulutsa fumbi loyera kwambiri la ≤5mg/Nm3 kuchokera ku chosonkhanitsira fumbi, zomwe zimathandiza kuti makampani opanga simenti apeze mpweya wochuluka komanso wochepa wa kaboni.
Pakupanga simenti, fumbi lalikulu lokhala ndi kutentha kwambiri, chinyezi chambiri komanso mpweya wowononga lidzapangidwa. Zipangizo zosefera za fiberglass zimatha kuchotsa utsi ndi fumbi, ndipo zimakhala ndi mawonekedwe oletsa kutentha kwambiri, kukana dzimbiri komanso kukana kuzizira. Kutuluka kwa zida zosefera za fiberglass kwabweretsa mwayi wokonzanso chitukuko cha mafakitale a simenti.

Kugwiritsa ntchito zipangizo zopangidwa ndi fiberglass composite poteteza chilengedwe, photovoltaic, mphamvu ya mphepo, zomangamanga, magalimoto, kulumikizana, zomangamanga ndi zina. Pakati pa izi, fyuluta ya fiberglass ndi imodzi mwamagawo ofunikira kwambiri pakukulitsa kwake kwambiri.

Tapanga bwino mitundu yosiyanasiyana ya matumba otetezera chilengedwe: matumba osakaniza a GF (fiberglass), matumba osakaniza a PTFE (polytetrafluoroethylene), matumba osakaniza a PPS (polyphenylene sulfide), matumba osakaniza a polyester, ndi zina zotero. Pakati pawo, thumba losakaniza la GF loteteza chilengedwe limagwiritsa ntchito nsalu yosakaniza ya ulusi wagalasi ngati chonyamulira, nembanemba ya ePTFE yophatikizika, ndipo pamapeto pake limakonzedwa kukhala thumba losakaniza lomalizidwa, lomwe lili ndi mawonekedwe otsutsana ndi kutentha kwambiri, kulondola kwambiri kwa kusefa, nthawi yayitali yoyeretsera, kukana okosijeni ndi kukana dzimbiri.
Ndi kukhazikika pang'onopang'ono kwa ntchito zoyambira, matumba osinthira a GF apeza zotsatira zabwino zogwiritsidwa ntchito kumapeto kwa uvuni wa simenti, ndipo chifukwa cha kukonza bwino ndi kukonza njira yochotsera fumbi pamutu wa uvuni wa simenti, liwiro la mphepo yosefera ya mitu ina ya uvuni latsika kufika pa 0.8 m/mphindi kapena pansi, ndipo utsi Kuchepa kwa tinthu tating'onoting'ono tambiri mumlengalenga kwachepetsa kwambiri mphamvu ya fyuluta yophimbidwa ndi nembanemba, ndipo kugwiritsa ntchito matumba osinthira a GF pamutu wa uvuni wa simenti kukulowa m'malo mwa zinthu zina pang'onopang'ono.
