I-r-kukosha kwezvimwe zvakasiyana-siyana zvekudzivirira zvinokonzera kushandiswa kwemagetsi
R-kukoshesa, maererano neshoko rekusungirirwa , rinoreva kushandiswa kwemafuta kune zvakasiyana-siyana zvekudzivirira zvinhu. Iyo yakakosha R-inokosha yezvinhu, zviri nani iyo inopisa kubva kune kupisa uye kutonhora. R-kukosha kwekusungirirwa kunoenderana nemhando yezvinyorwa, kubwinya kwayo uye kuwanda kwayo.
R-Maonero: The Basic Physics
Mukutaura kwakajeka, kupisa kunoenda kunzvimbo inopisa kusvika kune inotonhorera kusvikira kusisina musiyano mukupisa kwezvinhu zviviri.
Mumusha mako, kupisa kunotungamira kubva kunzvimbo inotonhora kusvika munzvimbo inotonhora (kana kunze) kuburikidza nenzvimbo ipi neipi yakazaruka, kufanana nehwindo rakapwanyika, mazamu ari mukova jamb kana maduku maduku akafanana neaya ari mumadziro emadziro.
Utsi huchafambisawo kuburikidza nezvinhu zvakadai seplywood, drywall, girasi, krete uye zvimwe zvinhu zvokuvaka. Muchitonhora mamiriro okunze, kupisa kunobuda mukati meimba kune nzvimbo inotonhorera, kazhinji kunze. Mumamiriro okunze ekudziya, kupisa kunofamba kune imwe nzvimbo yakatarisana, kubva kunze kuenda kunzvimbo inotonhorera mukati.
Kusungirirwa naizvozvo zvakakosha kuti uchengete kupisa kwairi, nekuderedza kupisa kwako uye mafungiro emhepo. Kunyange zvazvo zvivako zvose zvekuvaka zvine rumwe ruzhinji rweR-kukosha kukwikwidza kupisa kufamba, kusungirirwa kunowedzera kuwedzera kwe-R kwemasvingo, denga, pasi kana chimwe chivako chekuvaka.
Semumwe muenzaniso, drywall pa 1/2 "kuwanda kune R-inokosha ye 0.45 - yepamusoro pari kukosha. Zvimwe zvinowanikwa mumadziro emadziro zvine zvimwe zvakaderera zvinokosha: 1/2" kunze kweplywood zvine R-inokosha ye 0.63, uye kunze huni bevel siding ine R-yenhamba ye 0.80 chete.
Asi paunowedzera 3-1 / 2 "ye-fiberglass isolation, ine R-inokosha ye11.0, rusvingo rwuri hwose runogona kushandiswa kwemafuta anosvika 14 - kwete zvakaipa, asi kwete zvakanaka, kunyanya kunotonhora kana kupisa kwazvo mahara.
Mawindo nemasuwo kazhinji ndiyo nzvimbo huru dzekushaya kwehupfumi mune chimwe chivako, sezvo ma-R-maitiro avo anowanzove akaderera zvakanyanya kudarika ma-R anokosha emusvingo wakasimba.
Pane imwe chete yegirazi ine R-inokosha yekutangira 0.91 - kuwedzera dutu remhepo richaputika iro rinokosha kusvika kune inenge 2.0. Girazi yechitatu-yakasara ne 1/2 "nzvimbo pakati pepenes ine R-inokosha ye 3.23 (asi haiwanzoshandiswa nokuti inodhura uye inorema).
Zvinhu Zvokuvakwa neHigh R-Value
Zvakakosha kuziva kuti R-maitiro haagari kune dzimwe nzvimbo. Muzvivakwa zvakasongedzwa zvakagadziriswa, zvigadziro zvemasvingo zvemasvingo hazvina kuvhara uye zvinogona kutumisa kupisa nyore nyore mukugadzirisa kunonzi "kubata." Nokuda kwechikonzero ichocho, vatsoropodzi vakawanda vanopikisa kuti r-kukosha haisi iyo nzira yakanaka yekuyera kukosha kwekuchengetedza kwekwakagadzika kese musangano.
Sangano reStalural insulated panels, kana SIPs, rakasimba panels ye OSB (yakagadzirirwa strand board) sheathing uye nheyo yakasimba yepamusoro. Chimiro chakafanana chakagadzirwa neSIP chivakwa chinogona kuva ne-R inokosha pakati pe15 ne20, maererano nezvose zvinyorwa.
Kumbani yeCisf inoshandisa kutyora maekrete maitiro akaitwa kubva pakusvibiswa kwema polystyrene foam. Aya mabhokwe asina kudzikidzwa akaiswa mukati kuti agadzire kunze kwemasvingo. Kana yakakwana, mukati mehuta hwakazadzwa nekrete-yakasimbiswa krete kuti igadzire simba rakasimba, rine simba. ICF masvingo anowanzova ne-R maitiro anosvika 20.
Payback Period for Added Insulation
Chero ani zvake anofunga nezvekuvakwa patsva angaita zvakanaka kuti aongorore mari, zvikomborero uye nguva dzekubhadhara dzezvi uye zvimwe zvezvinhu zvitsva zvekuvaka kuitira kuvandudza magetsi.
Kuvandudza huwandu hweR-mumasvingo ako emisha aripo, pedenga uye padenga, Dhipatimendi reMagetsi rinokurudzira kuti uongorore machira, masvingo nepasi pedo nenzvimbo ipi zvayo isina kufanana, segaraji kana pasi. Iwe unokwanisa kuona kuti ndeupi rudzi rwekusungirirwa kwaunayo uye unoyera hurefu hwahwo kana hutete.
Nenzira yakanaka, kuwedzera kuisa pfungwa inzira inotengeswa yekuchengetedza simba nemari. Zvichienderana nezvamunogara uye kuti zvakanyanya sei kusungirirwa iwe unoda, nguva yekubhadhara yokuwedzera kuisa pfungwa inogona kuva shoma semakore mashoma. Semuenzaniso, kuwedzerwa R-kukosha kwekutengesa kwako kweputika kubva pa19 kusvika ku30 nekuwedzera bhatt-insulation ne-R-nhamba ye11 inogona kuchengetedza mari yakawandisa mumadhora ekuderedza anokonzera kuti nguva yake yekubhadhara inopfuura makore mashanu.
