Umyinge wokuhanjiswa komphunga wamanzi (WVTR) wokugquma yinto ebalulekileyo ekufuneka iqwalaselwe xa kuyilwa naxa kusakhiwa izakhiwo.I-WVTR lizinga apho umphunga wamanzi udlula khona kwizinto ezifana nokugquma, kwaye udla ngokulinganiswa ngeegram/square meter/ngosuku.Ukuqonda i-WVTR yezinto zokugquma kunganceda abayili bezakhiwo, iinjineli kunye neekontraka ukuba benze izigqibo ezizizo malunga nezona mathiriyeli zifanelekileyo zokusebenzisa kwizakhiwo ukunqanda iingxaki ezinxulumene nokufuma.
Ukugquma kwe-thermal kudlala indima ebalulekileyo ekudaleni indawo epholileyo, eyonga amandla angaphakathi.Inceda ukulawula ukushisa ngaphakathi kwesakhiwo kunye nokunciphisa ukuhanjiswa kobushushu phakathi kwendawo yangaphakathi nangaphandle.Nangona kunjalo, ukugquma kukwafuna ukulawula ukuhamba kokufuma ukuthintela iingxaki ezinjengokukhula komngundo, ukubola, kunye nokuncipha kokusebenza kokugquma ngokwayo.
Iindidi ezahlukeneyo zemathiriyeli yokugquma zinexabiso elahlukileyo le-WVTR.Umzekelo, ukugqunywa kwamagwebu ngokuqhelekileyo kune-WVTR ephantsi xa kuthelekiswa ne-fiberglass okanye i-cellulose insulation.Oku kuthetha ukuba ayingeneki kangako kumphunga wamanzi, ibonelela ngolawulo olungcono lokufuma kwizakhiwo.Nangona kunjalo, i-WVTR ye-insulation material ayikuphela kwento ekufuneka uyiqwalasele xa ukhetha imathiriyeli efanelekileyo.Ezinye izinto, ezifana nemozulu yesakhiwo, ubukho bokuthintela umphunga kunye noyilo lwesakhiwo ngokubanzi, nazo zidlala indima ebalulekileyo kulawulo lokufuma.
Kubalulekile ukulinganisa phakathi kokulawula ukufuma kunye nokufumana umoya ofanelekileyo.Izakhiwo ezingenamoya kakhulu zinokuqokelela ukufuma ngaphakathi, okubangela imiba yokufuma kunye nomonakalo onokuthi ubekho kwisakhiwo.Kwelinye icala, izakhiwo ezinemingxuma zinokuvumela ukufuma okugqithisileyo kungene, kubangele iingxaki ezifanayo.Ukuqonda i-WVTR yesixhobo sokugquma kunganceda abakhi bezakhiwo kunye nabakhi bafumane ibhalansi elungileyo ukuhlangabezana neemfuno ezikhethekileyo zesakhiwo.
Kwiimozulu ezibandayo, kubalulekile ukusebenzisa i-insulation kunye ne-WVTR ephantsi ukuthintela ukukhuhlaza ukuba kufakwe ngaphakathi kweendonga okanye uphahla.Ukujiya kunokubangela ukukhula komngundo, kubeke imingcipheko yempilo kubahlali, kunye nezinto zokwakha eziwohlokayo ngokuhamba kwexesha.Kwiimozulu ezishushu, ukugquma nge-WVTR ephezulu kunokufaneleka ngakumbi ukuvumela ukufuma ukuba kuphume kwaye kuthintele ukwakheka kokufuma.
Ngokuqhelekileyo ifakwe kwicala elifudumeleyo lokugquma, isithintelo somphunga sikwadlala indima ebalulekileyo ekulawuleni ukufuma.Banceda ukulawula ukuhamba komphunga wamanzi kwaye bawuthintele ekungeneni kwimvulophu yokwakha.Ukuqonda i-WVTR yokugquma kunye nezithintelo zomphunga kubalulekile ekuqinisekiseni ulawulo olusebenzayo lokufuma ngaphakathi kwesakhiwo.
Ngamafutshane, izinga lokuhanjiswa komphunga wamanzi lidlala indima ebalulekileyo ekulawuleni ukufuma kwisakhiwo.Ngokuqonda i-WVTR yezinto ezahlukeneyo zokugquma kunye nokuqwalasela ezinye izinto ezifana nemozulu kunye noyilo lwesakhiwo, abayili bezakhiwo, iinjineli kunye neekontraka banokwenza izigqibo ezinolwazi malunga nolona hlobo lokugquma kweprojekthi ethile.Oku kunceda ukuthintela iingxaki ezinxulumene nokufuma kwaye kudala indawo epholileyo, esempilweni, eyonga amandla ngaphakathi kwindlu yokwakha abantu abahlala kuyo.
