Yethu eyenzelwe ngokukhethekileisembozo sangaphezulu esiphefumulayoYenzelwe ngobungcweti izitsha ze-tote ze-IBC zezimboni ezijwayelekile, inikeza ikhambi elifanele lokuvikela lonke indawo yokugcina uketshezi nezinto ezibonakalayo. Isebenzisa isakhiwo se-membrane esithuthukisiwe esinezimbobo ezincane, lokhuisembozo sangaphezulu esiphefumulayoigcina ukujikeleza komoya kwangaphakathi okuqhubekayo ngenkathi ivimba amanzi angaphandle, uthuli kanye nokungcola.Isembozo sangaphezulu esiphefumulayokunciphisa kakhulu umehluko wokushisa obangelwa ukujiya ngaphakathi kwamathangi e-IBC, kuvimbela ngempumelelo ukuqongelela komswakama, isikhunta, ukugqwala kanye nokuwohloka kwezimpahla ezigciniwe, futhi kugcina kahle indawo yangaphakathi yomile futhi izinzile.
Yenziwe ngezinto ezisezingeni eliphezulu ezimelana nesimo sezulu esinzima, i-IBCisembozo sangaphezulu esiphefumulayoinezici ezinhle kakhulu zokumelana ne-UV, ukumelana nemvula nokusebenza kahle kokuvikela uthuli.Isembozo sangaphezulu esiphefumulayoingamelana nokuchayeka isikhathi eside ngaphandle, izinguquko zokushisa okukhulu, ukuguguleka komoya nokukhanya kwelanga ngaphandle kokuguga, ukufiphala noma ukuqhekeka. Umklamo wokuvala onqenqemeni olungiselelwe kahle ufanelana kahle nezimbobo eziningi zezitsha ze-IBC zomhlaba wonke, okwenza ukufakwa kube okuqinile nokuzinzile.
Ngenkathi inikeza isivikelo sangaphandle esithembekile,isembozo sangaphezulu esiphefumulayoivumela umoya opholile olinganiselayo ngaphandle komoya obandayo. Lesi simbozo esisebenzayo sandisa isikhathi sokugcina izinto eziningi ngaphakathi kwe-IBC futhi sehlisa kakhulu izindleko zokulungisa. Isakhiwo esilula sivumela ukufakwa okulula, ukushintshwa kanye nokugcinwa kwansuku zonke. Ngokukhululeka komswakama okusebenzayo, ukuvikela isimo sezulu kanye nokuphila isikhathi eside kwenkonzo, i-IBC yethuisembozo sangaphezulu esiphefumulayoiyisengezo esibalulekile sokuvikela sendawo yokugcina impahla yezimboni, indawo yokugcina impahla yangaphandle kanye nokuthuthwa kwezinto ezithwalayo zezitsha ze-IBC.
