Ixabiso le-U leemveliso zokukhusela ubushushu lingakanani?

Ixabiso le-U, elaziwa ngokuba yi-U-factor, lixabiso elibalulekileyo kwicandelo leemveliso zokukhusela ubushushu. Limela isantya apho ubushushu budluliselwa khona ngezinto. Okukhona ixabiso le-U liphantsi, kokukhona ukusebenza kokukhusela ubushushu kwemveliso kungcono. Ukuqonda ixabiso le-U lemveliso yokukhusela ubushushu kubalulekile ekwenzeni izigqibo ezinolwazi malunga nokusebenza kakuhle kwamandla kwesakhiwo kunye nentuthuzelo.

Xa ucinga ngemveliso yokukhusela ubushushu, kubalulekile ukuqonda ixabiso layo le-U ukuze kuvavanywe ukusebenza kwayo ekuthinteleni ukulahleka okanye ukwanda kobushushu. Oku kubaluleke kakhulu kwishishini lokwakha, apho ukusebenza kakuhle kwamandla kunye nozinzo zizinto ezibalulekileyo ekufuneka ziqwalaselwe. Ngokukhetha iimveliso ezinexabiso eliphantsi le-U, abakhi kunye nabanini bezindlu banokunciphisa ukusetyenziswa kwamandla kwaye banciphise iindleko zokufudumeza kunye nokuphola.

Ixabiso le-U leemveliso zokwambathisa lichaphazeleka zizinto ezifana nohlobo lwezinto, ubukhulu, kunye noxinano. Umzekelo, izinto ezifana ne-fiberglass, i-cellulose, kunye ne-foam insulation zinexabiso le-U ezahlukeneyo ngenxa yokuqhuba kobushushu obahlukeneyo. Ukongeza, ukwakhiwa kunye nokufakelwa kwe-insulation kuya kuchaphazela ixabiso layo le-U iyonke.

Ukuze kuchongwe ixabiso le-U lemveliso ethile yokwambathisa, umntu kufuneka abhekisele kwiinkcukacha zobugcisa ezibonelelwe ngumvelisi. Ezi nkcukacha zihlala ziquka ixabiso le-U, elichazwa kwiiyunithi ze-W/m²K (iiWatts ngemitha yesikwere nganye kwiKelvin). Ngokuthelekisa ixabiso le-U leemveliso ezahlukeneyo, abathengi banokwenza ukhetho olunolwazi malunga nokuba zeziphi izinto zokwambathisa ezifanelekileyo kwiimfuno zabo.

Ngamafutshane, ixabiso le-U lemveliso yokukhusela ubushushu lidlala indima ebalulekileyo ekuvavanyeni ukusebenza kwayo kobushushu. Ngokuqonda nokuqwalasela ixabiso le-U xa ukhetha izixhobo zokukhusela ubushushu, abantu kunye namashishini banokuba negalelo ekongeni amandla kwaye benze iindawo zokuhlala nezokusebenza ezikhululekileyo nezizinzileyo. Kubalulekile ukubeka phambili iimveliso ezinexabiso le-U eliphantsi ukuze kubekho ukusebenza kakuhle kwamandla kunye nentuthuzelo yobushushu.
