Igalaji livamise ukuba yindawo enkulu yokuvula indlu, okwenza ibe sengozini enkulu ngenxa yesimo sezulu esibi kakhulu.Isicabha segaraji esivalekile singasiza ekunciphiseni ukudluliswa kokushisa noma komoya obandayo egaraji lakho nakwezinye izindawo zekhaya lakho, ngaleyo ndlela kuthuthukise ukusebenza kahle kwekhaya lakho kukonke.
Lapho wenza ucwaningo ngezinhlobo ezahlukene zeminyango yegaraji, kungenzeka ukuthi uhlangabezane nesilinganiso "se-R-Value" esihlotshaniswa nokufakwa kweminyango yegalaji.
Iyini i-R-Value?
I-R-Value isilinganiso sokumelana nokushisa esisetshenziswa embonini yezokwakha neyokwakha.Ngokucacile, i-R-Value ukumelana nokushisa kokugeleza kokushisa.Abakhiqizi abaningi basebenzisa ama-R-Values ukukhombisa ukusebenza kahle kwamandla komkhiqizo wabo.Le nombolo ibalwa ngokususelwa kubukhulu be-insulation kanye nezakhiwo zayo zamakhemikhali.
Iqiniso Ngama-R-Values
Uma iphakeme i-R-Value, iba ngcono izakhiwo zokuvikela impahla.Nokho, inani le-R-16 alilihle ngokuphindwe kabili kuneVeni lika-R-8.Ayinikezi ukumelana nokushisa okuphindwe kabili noma kabili ukonga kwamandla.Inani le-R-16 linikeza ukwehlisa ngo-5% kokugeleza kokushisa kanye nokuthuthukiswa kokungu-5% ekusebenzeni kahle kwamandla ngaphezu kwevelu engu-R-8.Bona ishadi ukuze uthole ukuqhathaniswa Kwenani le-R.
