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.
