Uma usemkhakheni wezokwakha noma uhlela ukufaka ikhaya, kungenzeka ukuthi ulitholile igama elithi vapor lamanzi okuphelele (WVP). Kepha yini ngempela i-WVP? Kungani kubalulekile lapho ukhetha izinto zokufaka?
I-Water Vapor Permeability (WVP) iyisilinganiso sekhono lezinto ezibonakalayo zokuvumela ukudlula komphunga wamanzi. I-WVP iyinto ebalulekile okufanele icatshangelwe uma kukhulunywa ngokufakwa njengoba kuthinta ukusebenza okuphelele kokufakwa kokugcina imvelo engaphakathi esebenza kahle.
Izinto zokufakwa nge-WVP ephansi zingavimba ngempumelelo ukwakheka komswakama ngaphakathi kokwakha izindonga nophahla. Lokhu kubalulekile ngoba umswakama ophezulu kungaholela ekukhuleni kokubumba kanye nokulimala okuhlelekile ngokuhamba kwesikhathi. Ngakolunye uhlangothi, izinto zokwakha ezinama-WVP aphezulu zivumela umswakama owengeziwe ukuze udlule, okungahle kube yinzuzo ezimweni ezithile lapho kusetshenziswa khona umswakama.
Ngakho-ke, kanjani ukunquma i-WVP yezinto zokwakha zokufakelwa? I-WVP yezinto ezibonakalayo ngokujwayelekile ilinganiswa kumagremu ngemitha ngayinye yesikwele ngosuku (G / M² / Day) futhi ingahlolwa kusetshenziswa izindlela ezijwayelekile njenge-ASTM E96. Lezi zivivinyo zibandakanya ukudalula okuqukethwe kuzimo zomswakama olawulwayo kanye nokulinganisa izinga lapho umphunga wamanzi adlula khona ngesampula esikhathini esithile.
Lapho ukhetha izinto zokufakwa kwephrojekthi, kubalulekile ukubheka izidingo ezithile zesimo sezulu nezakhiwo. Isibonelo, ezimweni ezibandayo lapho ukufudumeza kudinga khona iningi lonyaka, kubalulekile ukukhetha ukufakwa nge-WVP ephansi ukuvikela umswakama owakha umswakama kanye nomonakalo ongaba khona esakhiweni sokwakha. Ngakolunye uhlangothi, ezimweni zezulu ezishisayo nezinomswakama, izinto ezinama-WVP aphezulu zingakhethwa ukuze zifinyelele ekuphathweni okungcono komswakama futhi zivikele ukubekezelela ngaphakathi kodonga.
Kunezinhlobo eziningi zezinto zokufaka ezifakwayo emakethe, ngayinye inezimpawu zayo ze-WVP. Isibonelo, izinto zokufakwa kwe-Foam ezifana ne-polyurethane ne-polystyrene ngokuvamile zine-WVP ephansi, zibenze balungele ukusetshenziswa ezindaweni ezibandayo nezimanzi. Ngokwesinye isikhathi ukufakwa kwe-cellulose kanye ne-fiberglass, kune-WVP ephezulu, kubenza balungele kangcono isimo sezulu esishisayo nesinomswakama.
Ngaphezu kokucatshangelwa kwesimo sezulu, indawo kanye nokusetshenziswa kokufakelwa kumele futhi kubhekwe. Isibonelo, ukufakwa egumbini elingaphansi noma endaweni yokukhasa kungadinga okubonakalayo nge-WVP ephansi ukuvikela umswakama kusuka ekungeneni izindonga zesisekelo. Ngokuphambene nalokho, ukufakwa kwe-attic kungazuza ngezinto zokwenziwa nge-WVP ephakeme yokuphathwa okungcono komswakama nokuvikelwa ekuvuseleleni amandla.
Ekuphetheni, i-Water Vapor Permeability (WVP) iyinto ebalulekile okufanele icatshangelwe lapho ukhetha izinto zokufakwa kwiphrojekthi yokwakha. Ukuqonda izakhiwo ze-WVP zezinto ezihlukile nokuthi zithinta kanjani ukuphathwa komswakama nokusebenza okuphelele kokwakha kubalulekile ekuqinisekiseni indawo yokuhlala ethandekayo futhi enempilo. Ngokucabanga ngesimo sakho esithile sezulu sezulu, indawo, kanye nesicelo sokufaka, ungenza isinqumo esinolwazi mayelana nokufakelwa okuhle kakhulu kwephrojekthi yakho.
