Ukushisa, okwaziwa nangokuthi ukushisa, kuyisici esibalulekile esinquma umphumela wokushisa kwezakhiwo. Kukala ikhono lezinto zokwakha lokuhambisa ukushisa futhi kuyinto ebalulekile okufanele icatshangelwe lapho ukhetha izinto zokwakha ukufudumala. Ukuqonda ukushisa kokushisa kokushisa kungasiza abanikazi bezindlu nabakhi ukuthi benze izinqumo ezinolwazi mayelana nohlobo oluhle kakhulu lokushisa okufanele balusebenzise emakhaya abo.
Ukushisa okushisayo kuyisilinganiso sekhono lento yokushisa. Kuvezwa ngama-watts ngemitha ngayinye nge-degree Celsius (W/mK) futhi kubonisa izinga lokushisa elidluliselwa ngalo ngento. Izinto ezinokushisa okuphansi ziyi-insulator engcono ngoba azikwazi ukufudumala kahle.
Uma kukhulunywa ngokufakwa kokushisa, ukuhanjiswa kokushisa kudlala indima ebalulekile ekunqumeni ikhono lento yokugcina isakhiwo sifudumele ebusika futhi sipholile ehlobo. Ukufakwa kokushisa kusebenza ngokubamba amaphakethe omoya ngaphakathi kwesakhiwo saso, kudala isithiyo esinciphisa ukudluliselwa kokushisa. Izinto ezinokufakwa kokushisa okuphansi zivimbela ngempumelelo ukushisa ukuthi kungaphumi noma kungene esakhiweni, kunciphisa izindleko zamandla futhi kuthuthukise induduzo yomuntu ohlala kuso.
Ukushisa komoya kwezinto zokushisa kungahluka kuye ngohlobo lwezinto ezisetshenziswayo. Isibonelo, i-fiberglass kanye ne-cellulose insulation zine-thermal conductivity engaba ngu-0.04-0.05 W/mK, kuyilapho i-spray foam insulation ingaba ne-thermal conductivity ephansi njengo-0.02 W/mK. Ngenxa yokushisa kwazo okuphansi, lezi zinto zibhekwa njengezivikela-moya ezisebenzayo.
Uma ukhetha uhlobo olufanele lokufakwa kokushisa kwesakhiwo, kubalulekile ukuqonda ukuhanjiswa kokushisa kwe-insulation. Izici ezifana nesimo sezulu, ukwakheka kwesakhiwo kanye nokukhetha komuntu siqu konke kudlala indima ekunqumeni izinto zokufakwa kokushisa ezingcono kakhulu. Uma ukhetha inketho efanele kakhulu yesakhiwo esithile, kubalulekile ukucabangela inani le-R kanye nokuhanjiswa kokushisa kwento yokufakwa kokushisa.
Ezimweni ezibandayo, lapho izindleko zokushisa ziyinkinga, kubalulekile ukukhetha izinto zokuvikela ezinokushisa okuphansi ukuze kuncishiswe ukulahleka kokushisa. Ezimweni ezifudumele, ukugxila kungaba ekuvimbeleni ukwanda kokushisa, ngakho-ke ukuvikela okunokushisa okuphansi kubaluleke ngokulinganayo. Ngokuqonda ukufudumala kokushisa kokushisa, abanikazi bezindlu nabakhi bangakhetha ukuvikela okusebenzayo kakhulu ngokusekelwe ezidingweni zabo ezithile.
Ngamafuphi, ukuhanjiswa kokushisa kwezinto ezivikela ukushisa kuyisici esibalulekile ekunqumeni ikhono lezinto ezivikela ukushisa. Izinto ezivimbela ukushisa okuncane ziyizivikeli ezivikela ukushisa ezingcono, ezisiza ekuthuthukiseni ukusebenza kahle kwamandla kanye nenduduzo yesakhiwo. Ngokuqonda ukuhanjiswa kokushisa kwezinto ezivikela ukushisa kanye nokubaluleka kwako, abanikazi bezindlu nabakhi bangenza izinqumo ezinolwazi mayelana nohlobo olungcono kakhulu lokufudumala okufanele balusebenzise emakhaya abo.
