Garaashku inta badan waa albaabka ugu weyn ee guriga, taas oo ka dhigaysa mid aad ugu nugul cimilada.Albaabka garaashka ee dahaaran ayaa kaa caawin kara yaraynta ku wareejinta kulaylka ama hawo qabow ee geerashkaaga iyo meelaha kale ee gurigaaga, sidaas darteed waxay hagaajinaysaa waxtarka tamarta guud ee gurigaaga.
Markaad samaynayso cilmi-baaris ku saabsan noocyada kala duwan ee albaabbada garaashka, waxaa laga yaabaa inaad la kulantay cabbir "R-Value" oo la xidhiidha dahaarka albaabka garaashka.
Waa maxay R-Qiimaha?
R-Qiimaha waa cabbirka caabbinta kulaylka ee loo isticmaalo dhismaha iyo warshadaha dhismaha.Gaar ahaan, R-Value waa iska caabbinta kulaylka socodka kulaylka.Soosaarayaal badan ayaa isticmaala R-Qiimaha si ay u muujiyaan waxtarka tamarta alaabtooda.Tiradan waxaa lagu xisaabiyaa iyadoo lagu salaynayo dhumucda dahaarka iyo sifooyinkiisa kiimikaad.
Xaqiiqada Ku Saabsan Qiimaha R
Markasta oo uu sareeyo R-Qiimaha, ayaa ka sii wanagsan sifooyinka dahaarka ee walxaha.Si kastaba ha ahaatee, qiimaha R-16 laba jeer kama wanaagsana qiimaha R-8.Ma bixiso laba jeer in ka badan iska caabbinta kulaylka ama laba jeer kaydka tamarta.Qiimaha R-16 wuxuu bixiyaa 5% hoos u dhaca socodka kulaylka iyo 5% hagaajinta waxtarka tamarta marka loo eego qiimaha R-8.Eeg jaantuska isbarbardhigga R-Qiimaha.
