Liyini inani le-R le-insulation?

Uma uthenga izinto ezifakwa ngaphakathi, kungenzeka ukuthi uhlangabezane negama elithi “R-value.” Kodwa kuyini ngempela? Kungani kubalulekile lapho ukhetha i-insulation efanele yendlu yakho?

Inani le-R lesivikeli mandla liyisilinganiso sokumelana kwaso nokushisa. Kalula nje, kukhombisa ukuthi i-insulation imelana kanjani nokugeleza kokushisa. Lapho inani le-R liphezulu, kuba ngcono ukuvaleka kwakho ekugcineni ufudumele ebusika futhi upholile ehlobo.

I-R-value iyisici esibalulekile okufanele icatshangelwe lapho ukhetha ukufakwa kwendlu yakho. Ingakusiza ukuthi unqume uhlobo olulungile kanye nenani le-insulation elidingekayo ukuze ulawule kahle izinga lokushisa lekhaya lakho futhi unciphise izindleko zamandla.

Izindawo ezihlukene zekhaya lakho zingase zidinge amanani e-R ahlukene, kuye ngesimo sezulu sakho kanye nenani le-insulation ekhona. Isibonelo, ukufakwa kwe-attic ngokuvamile kudinga inani eliphakeme le-R kunokufakwa odongeni ngoba ukushisa kuvame ukukhuphuka kuphume ku-attic.

Umnyango Wezamandla wase-US unikeza imihlahlandlela enconyiwe yenani lika-R ngokusekelwe endaweni yesimo sezulu. Le mihlahlandlela ingasiza abanikazi bezindlu nabakhi banqume inani elifanele le-R lendawo yabo ethile.

Ezimweni ezibandayo, amanani aphezulu e-R ayanconywa ukunciphisa ukulahleka kokushisa nokunciphisa ukusetshenziswa kwamandla. Ezimweni ezifudumele, inani elingu-R eliphansi lingase lanele ukuvimbela ukwanda kokushisa nokugcina izinga lokushisa elikhululekile lasendlini.

Kubalulekile ukuqaphela ukuthi inani le-R liyisici esisodwa nje okufanele sicatshangelwe lapho ukhetha izinto zokufakelwa. Ezinye izici ezifana nokumelana nomswakama, ukuphepha komlilo kanye nezindleko zokuwufaka nazo kufanele zicatshangelwe.

Kunezinhlobo eziningi zezinto zokufakelwa ezitholakalayo, ngayinye inenani layo elingu-R. I-Fiberglass, i-cellulose, ibhodi legwebu, kanye negwebu lokufutha ngezinye zezinketho ezivamile, ngayinye ihlinzeka ngamavelu e-R ahlukene nezindlela zokuyifaka.

Uma uqhathanisa izinto zokufakelwa, ungacabangi nje kuphela inani le-R, kodwa futhi nokusebenza okuphelele nokuhlala isikhathi eside kwezinto zokufakelwa. Izinto ezithile zingase zibe nenani elingu-R eliphakeme kodwa zingase zingasebenzi kahle ezimeni ezithile noma zidinge ukunakekelwa okwengeziwe ngokuhamba kwesikhathi.

Ngokungeziwe ekukhetheni okokusebenza okufanele kokufakwayo, ukufakwa okufanele kubalulekile ekwandiseni ukusebenza kahle kwe-R-value yakho. Izikhala, ukucindezelwa, nokuvuza komoya konke kungaphazamisa ukusebenza kwe-insulation, okuholela ekunciphiseni ukumelana nokushisa nokusebenza kahle kwamandla.

Ukuze uqinisekise imiphumela engcono kakhulu, kunconywa ukuthi uxhumane nosonkontileka ochwepheshile ongahlola izidingo ezithile zekhaya lakho futhi atuse uhlobo olufaneleka kakhulu lwe-insulation kanye nenani lika-R.

Kafushane, inani le-R lezinto ezifakwayo zidlala indima ebalulekile ekunqumeni ukumelana kwayo nokushisa kanye nokusebenza kahle kukonke ekulawuleni izinga lokushisa lekhaya lakho. Ngokwazi inani elinconyiwe le-R lendawo yakho nokukhetha okokufaka okulungile, ungathuthukisa ukusebenza kahle kwamandla, unciphise izindleko zokushisisa nokupholisa, futhi udale indawo yasendlini enethezeke kakhudlwana.
