Uma uthenga izinto zokuvikela ukushisa, kungenzeka ukuthi uke wahlangana negama elithi “R-value.” Kodwa liyini ngempela? Kungani kubalulekile lapho ukhetha izinto zokuvikela ukushisa ezifanele ikhaya lakho?
Inani le-R le-insulator liyisilinganiso sokumelana kwayo nokushisa. Kalula nje, libonisa ukuthi i-insulation imelana kahle kangakanani nokugeleza kokushisa. Uma inani le-R liphakeme, i-insulation ingcono kakhulu ekukugcineni ufudumele ebusika futhi upholile ehlobo.
Inani le-R liyisici esibalulekile okufanele usicabangele lapho ukhetha ukuvikela indlu yakho. Lingakusiza ukuthi unqume uhlobo olufanele kanye nenani lokuvikela indlu elidingekayo ukuze ulawule kahle izinga lokushisa lendlu yakho futhi unciphise izindleko zamandla.
Izindawo ezahlukene zekhaya lakho zingadinga amanani ahlukene e-R, kuye ngesimo sezulu sakho kanye nenani lokufakwa kokushisa okukhona. Isibonelo, ukufakwa kokushisa kwe-attic ngokuvamile kudinga inani eliphakeme le-R kune-wall insulation ngoba ukushisa kuvame ukukhuphuka nokuphuma nge-attic.
UMnyango Wezamandla wase-US unikeza iziqondiso zenani le-R ezinconyiwe ngokusekelwe endaweni yesimo sezulu. Lezi ziqondiso zingasiza abanikazi bezindlu nabakhi ukuthi banqume inani le-R elifanele lendawo yabo ethile.
Ezimweni ezibandayo, kunconywa amanani aphezulu e-R ukuze kuncishiswe ukulahleka kokushisa nokunciphisa ukusetshenziswa kwamandla. Ezimweni ezifudumele, inani eliphansi le-R linganele ukuvimbela ukwanda kokushisa nokugcina amazinga okushisa angaphakathi ekhululekile.
Kubalulekile ukuqaphela ukuthi inani le-R liyisici esisodwa okufanele usicabangele lapho ukhetha izinto zokuvikela ukushisa. Ezinye izinto ezifana nokumelana nomswakama, ukuphepha komlilo kanye nezindleko zokufaka nazo kufanele zicatshangelwe.
Kunezinhlobo eziningi zezinto zokuvikela ezitholakalayo, ngayinye inenani layo elingu-R. I-Fiberglass, i-cellulose, ibhodi le-foam, kanye ne-spray foam kuyizinketho ezivamile, ngayinye inikeza amanani ahlukene angu-R kanye nezindlela zokufaka.
Uma uqhathanisa izinto zokuvikela ukushisa, cabanga hhayi ngenani le-R kuphela, kodwa futhi nokusebenza kwayo yonke kanye nobude besikhathi sezinto zokuvikela ukushisa. Izinto ezithile zingaba nenani le-R eliphakeme kodwa zingase zingasebenzi kahle ezimweni ezithile noma zidinge ukulungiswa okwengeziwe ngokuhamba kwesikhathi.
Ngaphezu kokukhetha izinto zokuvikela ukushisa ezifanele, ukufakwa okufanele kubalulekile ukuze kukhuliswe ukusebenza kahle kwenani lakho le-R. Izikhala, ukucindezela, kanye nokuvuza komoya konke kungonakalisa ukusebenza kokuvikela ukushisa, okuholela ekunciphiseni ukumelana nokushisa kanye nokusebenza kahle kwamandla.
Ukuqinisekisa imiphumela emihle kakhulu, kutuswa ukuthi uthintane nochwepheshe wokufaka izinto zokuvikela uthuli ongahlola izidingo ezithile zendlu yakho futhi ancome uhlobo lokufaka izinto zokuvikela uthuli olufanele kakhulu kanye nenani elingu-R.
Ngamafuphi, inani le-R lezinto zokuvikela ukushisa lidlala indima ebalulekile ekunqumeni ukumelana kwazo nokushisa kanye nokusebenza kahle kokulawula izinga lokushisa lendlu yakho. Ngokwazi inani le-R elinconywayo lendawo okuyo nokukhetha i-insulation efanele, ungathuthukisa ukusebenza kahle kwamandla, unciphise izindleko zokushisa nokupholisa, futhi udale indawo ekhululekile yangaphakathi.
