Garaashku badanaa waa furitaanka ugu weyn ee guri, taas oo ka dhigaysa mid aad ugu nugul cimilada xag-jirnimada. albaabka garaashka oo lagu ayaa kaa caawin kara yareynta u soo wareejinta kuleylka ama hawo qabow garaashkaaga iyo meelaha kale ee gurigaaga, taasoo markaa hagaajinaysa waxtarka guud ee tamarta gurigaaga.

Markaad samaynayso cilmi baaris ku saabsan noocyada kala duwan ee garaashyada, waxaa laga yaabaa inaad la kulantay cabbir "R-Value" oo la xiriira dahaadhka albaabka garaashka.

Waa maxay R-Value?

R-Value waa cabbir kuleylka kuleylka loo adeegsado dhismaha iyo warshadaha dhismaha. Gaar ahaan, R-Value waa iska caabbinta kuleylka ee socodka kuleylka. Soosaarayaal badan ayaa adeegsada R-Values ​​si ay u muujiyaan hufnaanta tamarta wax soo saarkooda. Lambarkan waxaa loo xisaabiyaa iyadoo lagu saleynayo dhumucda dahaarka iyo waxyaabaha kiimikada ay ka kooban tahay.

Runta ku saabsan R-Qiimayaasha

Markuu sare u kaco R-Value, ayaa ka sii fiicnaanaya sifooyinka dahaarka maaddada. Si kastaba ha noqotee, qiimaha R-16 uma fiicna laba jeer qiimaha R-8. Ma bixiso laba jibbaar iska caabbinta kuleylka ama laba jeer keydinta tamarta. Qiimaha R-16 wuxuu bixiyaa 5% hoos udhaca socodka kuleylka iyo 5% hagaajinta waxtarka tamarta ee qiimaha R-8.
