Iyo mvura vapor transmission rate (WVTR) yekudzivirira chinhu chakakosha kutariswa kana uchigadzira nekuvaka zvivakwa.WVTR ndiyo mwero wekuti mhute yemvura inopfuura nemuchinhu chakaita sekudzivirira, uye inowanzopimwa nemagiramu/square mita/zuva.Kunzwisisa iyo WVTR yezvinhu zvekudzivirira zvinogona kubatsira vavaki, mainjiniya nemakondirakiti kuita sarudzo dzine ruzivo nezvezvakanakisa zvekushandisa muzvivakwa kudzivirira matambudziko ane hunyoro.
Thermal insulation inoita basa rakakosha mukugadzira nharaunda yakagadzika, isina simba remukati.Inobatsira kugadzirisa kutonhora mukati mechivako uye kuderedza kupisa kwekushisa pakati pemukati nekunze.Nekudaro, kusungirira kunodawo kudzora kufamba kwemwando kudzivirira matambudziko akadai sekukura kwe mold, kuora, uye kuderedzwa kwekushanda kweiyo insulation pachayo.
Mhando dzakasiyana dzemidziyo yekuvharisa dzine hunhu hwakasiyana hweWVTR.Semuenzaniso, kupupa kwefuro kunowanzo kuve neWVTR yakaderera kana ichienzaniswa nefiberglass kana cellulose insulation.Izvi zvinoreva kuti haipindike kumhute yemvura, ichipa hunyoro huri nani muzvivakwa.Nekudaro, iyo WVTR yechinhu chekudzivirira haisiriyo chete chinhu chekufunga nezvacho pakusarudza chinhu chakakodzera.Zvimwe zvinhu, zvakaita semamiriro ekunze echivako, kuvapo kwechivharidzo chemhute uye dhizaini yese yekuvaka, inoitawo basa rakakosha mukutonga mwando.
Zvakakosha kuenzanisa kuenzanisa pakati pekudzora humidity uye mhepo yakakodzera.Zvivakwa zvisingapindi mhepo zvakanyanya zvinogona kuunganidza hunyoro mukati, zvichikonzera hunyoro nyaya uye zvinogona kukanganisa chimiro.Ukuwo, zvivakwa zvine porous zvinogona kubvumira mwando wakawandisa kupinda mukati, zvichikonzera matambudziko akafanana.Kunzwisisa WVTR yechinhu chekudzivirira kunogona kubatsira vavaki nevavaki kuwana mwero wakakodzera wekuzadzisa zvinodiwa nechivako.
Mumamiriro ekunze anotonhora, zvakakosha kushandisa insulation neWVTR yakaderera kudzivirira condensation kubva pakuumbwa mukati memadziro kana denga.Condensation inogona kukonzera mold kukura, kuisa njodzi dzehutano kune vanogaramo, uye kushata zvekuvaka nekufamba kwenguva.Mumamiriro ekunze anodziya, insulation ine WVTR yepamusoro inogona kunyatsokodzera kuti hunyoro hubude uye kudzivirira hunyoro kukwira.
Inowanzo kuisirwa padivi rinodziya rekudzivirira, chinovharira mhute chinoitawo basa rakakosha mukudzora hunyoro.Vanobatsira kudzora kufamba kwemhute yemvura uye kudzivirira kuti isapinda muhamvuropu yekuvaka.Kunzwisisa WVTR yekudzivirira uye zvipingamupinyi zvemhute kwakakosha kuti uve nechokwadi chekutonga hunyoro mukati mechivako.
Muchidimbu, mwero wekutapurirana kwehuputi hwemvura hwekudzivirira hunoita basa rakakosha mukugadzirisa hunyoro muchivako.Nekunzwisisa iyo WVTR yezvinhu zvakasiyana-siyana zvekudzivirira uye kufunga zvimwe zvinhu zvakaita semamiriro ekunze uye dhizaini yekuvaka, vagadziri vezvivakwa, mainjiniya uye makondirakiti vanogona kuita sarudzo dzine ruzivo nezve yakanakisa insulation yeimwe chirongwa.Izvi zvinobatsira kudzivirira matambudziko ane chekuita nehunyoro uye zvinogadzira nzvimbo yakagadzika, ine hutano, ine simba remukati mekuvaka vagari.
