Izinga lokudluliselwa komphunga wamanzi (i-WVTR) lokufakelwa kwezixhobo zokukhusela umoya liyinto ebalulekileyo ekufuneka iqwalaselwe xa kuyilwa kwaye kusakhiwa izakhiwo. I-WVTR lizinga apho umphunga wamanzi udlula khona kwizinto ezifana nokufakelwa kwezixhobo zokukhusela umoya, kwaye idla ngokulinganiswa ngeegrama/imitha yesikwere/ngosuku. Ukuqonda i-WVTR yezinto zokukhusela umoya kunokunceda abakhi bezakhiwo, iinjineli kunye nabakhi ukuba benze izigqibo ezinolwazi malunga nezinto ezifanelekileyo zokusetyenziswa kwizakhiwo ukuthintela iingxaki ezinxulumene nokufuma.
Ukufakwa kobushushu obuphezulu kudlala indima ebalulekileyo ekudaleni imeko-bume yangaphakathi ekhululekileyo neyonga amandla. Kunceda ekulawuleni ubushushu ngaphakathi kwesakhiwo kwaye kunciphisa ukudluliselwa kobushushu phakathi kwangaphakathi nangaphandle. Nangona kunjalo, ukufakwa kobushushu kufuneka kulawule ukuhamba komswakama ukuthintela iingxaki ezinjengokukhula kombungu, ukubola, kunye nokunciphisa ukusebenza kokufakwa kobushushu obuphezulu ngokwako.
Iintlobo ezahlukeneyo zezinto zokwambathisa zinexabiso elahlukileyo le-WVTR. Umzekelo, ukwambathisa i-foam kudla ngokuba ne-WVTR ephantsi xa kuthelekiswa ne-fiberglass okanye i-cellulose insulation. Oku kuthetha ukuba ayingeni kakhulu kumphunga wamanzi, nto leyo enika ulawulo olungcono lokufuma kwizakhiwo. Nangona kunjalo, i-WVTR yezinto zokwambathisa ayisiyonto yodwa ekufuneka iqwalaselwe xa ukhetha izinto ezifanelekileyo. Ezinye izinto, ezifana nemozulu yesakhiwo, ubukho bomqobo womphunga kunye noyilo lwesakhiwo siphela, nazo zidlala indima ebalulekileyo ekulawuleni ukufuma.
Kubalulekile ukuba kubekho ulungelelwano phakathi kokulawula ukufuma kunye nokungenisa umoya ngokufanelekileyo. Izakhiwo ezingenamoya kakhulu zinokuqokelela ukufuma ngaphakathi, nto leyo ebangela iingxaki zokufuma kunye nomonakalo onokubakho kwisakhiwo. Kwelinye icala, izakhiwo ezinemingxuma zinokuvumela ukufuma okugqithisileyo ukuba kungene, nto leyo ebangela iingxaki ezifanayo. Ukuqonda i-WVTR yezinto zokukhusela kunokunceda abakhi bezakhiwo kunye nabakhi ukuba bafumane ulungelelwano olufanelekileyo ukuhlangabezana neemfuno ezithile zesakhiwo.
Kwimozulu ebandayo, kubalulekile ukusebenzisa i-insulation ene-WVTR ephantsi ukuthintela ukuba i-condensation ingabikho ngaphakathi kweendonga okanye eluphahleni. I-condensation inokubangela ukuba i-mold ikhule, ibe yingozi kwimpilo yabantu abahlala kuyo, kwaye yonakalise izixhobo zokwakha ngokuhamba kwexesha. Kwimozulu efudumeleyo, i-insulation ene-WVTR ephezulu inokuba yeyona ifanelekileyo ukuvumela umswakama ukuba uphume kwaye kuthintelwe ukuqokelelana komswakama.
Ihlala ifakelwe kwicala elifudumeleyo le-insulation, i-vapor barrier ikwadlala indima ebalulekileyo ekulawuleni ukufuma. Inceda ekulawuleni intshukumo yomphunga wamanzi kwaye ithintele ukuba ungangeni kwi-envelope yesakhiwo. Ukuqonda i-WVTR ye-insulation kunye ne-vapor barriers kubalulekile ekuqinisekiseni ulawulo olusebenzayo lokufuma kwisakhiwo.
Ngamafutshane, izinga lokudluliselwa komphunga wamanzi kwi-insulation lidlala indima ebalulekileyo ekulawuleni ukufuma kwisakhiwo. Ngokuqonda i-WVTR yezinto ezahlukeneyo ze-insulation kunye nokuqwalasela ezinye izinto ezifana nemozulu kunye noyilo lwesakhiwo, abakhi bezakhiwo, iinjineli kunye nabakhi banokwenza izigqibo ezinolwazi malunga ne-insulation efanelekileyo kwiprojekthi ethile. Oku kunceda ukuthintela iingxaki ezinxulumene nokufuma kwaye kudala imeko-bume yangaphakathi ekhululekileyo, enempilo, neyonga amandla kubantu abahlala kwisakhiwo.
