Koj puas paub tias koj lub tsev lub qhov rooj sab nrauv yog ntau tshaj li kev txais tos nkag? Lawv yeej ua tau raws li ib txoj kab tseem ceeb ntawm kev tiv thaiv tus nqi zog poob. Qhov tseeb, qhov rais thiab qhov rooj suav txog li 25% ntawm lub tsev tag nrho cov cua sov thiab cua txias siv.
Ua qhov kev xaiv tsis raug tuaj yeem ua rau kom khov cov ntawv sau cia thiab cov nqi hluav taws xob nce siab. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau nug: dab tsi yog lub zog efficiency xav txog pem hauv ntej qhov rooj ? Xaiv txoj cai nkag yuav tsum nkag siab txog qhov sib txawv ntawm cov khoom sib txawv li cas sib ntaus sib tua.
Hauv tsab xov xwm no, koj yuav kawm raws nraim li cas los sib piv cov ntaub ntawv ntawm lub qhov rooj thiab qhov kev ua tau zoo. Peb tseem yuav tshawb nrhiav cov iav xaiv, cov kev xav tau ntawm huab cua tshwj xeeb, kev teeb tsa zoo tshaj plaws, thiab cov qhab nia muaj txiaj ntsig. Cia peb dhia mus rau hauv cov lus qhia kawg rau kev xaiv lub qhov rooj uas txuag koj nyiaj.
Nkag siab txog Kev Ntsuas Hluav Taws Xob rau Cov Qhov Rooj Pem Hauv Ntej
Ua ntej koj mus yuav khoom tshiab, koj yuav tsum nkag siab tias cov kws tshaj lij ntsuas li cas zog efficiency . Lawv siv cov kev ntsuas tshwj xeeb. Lub National Fenestration Rating Council (NFRC) daim ntawv lo yog tus qauv kub ntawm no. Nws muab koj cov lej tiag tiag uas koj xav tau. Koj tuaj yeem sib piv cov qhov rooj ncaj ncees thaum koj nyeem nws.
U-Factor: Qhov ntsuas hluav taws xob rwb thaiv tsev
Dab tsi yog U-Factor? Nws ntsuas seb lub qhov rooj tiv thaiv cua sov ntawm koj lub tsev li cas. Xav tias nws yog koj qhov ntsuas hluav taws xob rwb thaiv tsev. Ib txoj cai yooj yim siv ntawm no. Qhov qis dua U-Factor, qhov kev rwb thaiv tsev zoo dua. Cov qhov rooj ntoo ntoo feem ntau zaum ntawm 0.50 lossis siab dua. Lawv cia cua sov tawm tam sim ntawd. Sab saum toj-tier fiberglass qhov rooj, txawm li cas los xij, tuaj yeem ua tiav qhov zoo siab 0.09. Lawv khaws qhov sov so hauv qhov chaw nws nyob.
| Qhov Rooj Hom Hom | U-Factor |
|---|---|
| Tsob Ntoo Ntoo | 0.50+ |
| Sab saum toj-Tier Fiberglass | 0.09 |
Solar Heat Gain Coefficient (SHGC): Lub Hnub Ci Metric
Tom ntej no, peb saib hnub ci Heat Gain Coefficient, lossis SHGC. Nws ntsuas qhov zoo npaum li cas cov khoom thaiv hnub ci cua sov los ntawm koj qhov chaw. Cov kws tshaj lij ntsuas nws ntawm qhov ntsuas ntawm 0 txog 1. Vim li cas nws tseem ceeb heev? Nws dhau los ua qhov tseem ceeb thaum koj xaiv qhov rooj uas muaj cov iav ntxig. Lub hnub beams cua sov ncaj qha los ntawm cov iav dawb. Ib qho SHGC qis thaiv qhov tsis xav tau cua sov hauv huab cua kub. SHGC siab dua txais tos dawb hnub ci sov yog tias koj nyob hauv thaj chaw txias.
Tsawg SHGC: Qhov zoo tshaj plaws rau huab cua sov (thaiv cov cua sov).
High SHGC: Qhov zoo tshaj plaws rau cov huab cua txias (zoo siab txais tos cua sov).
Huab cua Leakage Ratings
Txawm tias lub qhov rooj tuab tshaj plaws yuav tsis yog tias cov cua ntsawj ntshab nyob ib puag ncig nws. Cov cua xau pov tseg lub zog loj. Peb ntsuas nws hauv cubic feet ib feeb ib square feet (cfm/ft²). Cov qhov rooj txheem feem ntau xau 1.0 cfm / ft² lossis ntau dua. Lawv cia sab nraum cua nchuav rau hauv. Lub qhov rooj siv hluav taws xob ua tau zoo dua. Lawv ua tiav 0.3 cfm / ft² lossis tsawg dua. Lawv kaw nruj nreem, txwv tsis pub cov nqi hluav taws xob tag nrho.
Cov ntaub ntawv qhov rooj thiab lawv qhov cuam tshuam rau kev siv hluav taws xob
Cov khoom uas koj xaiv txiav txim siab koj lub hauv paus rwb thaiv tsev thiab kev saib xyuas mus ntev. Cia peb tshawb nrhiav koj cov kev xaiv.
Fiberglass Qhov Rooj: Cov Hluav Taws Xob Hluav Taws Xob
Vim li cas fiberglass qhov rooj ua lag luam? Lawv ntim ib qho hnyav rwb thaiv tsev punch. Sab hauv, polyurethane ua npuas ncauj cores xa mus txog plaub npaug ntawm cov nqi insulating khoom ntoo. Koj tau txais txiaj ntsig R-nqi. Lawv feem ntau nyob ntawm R-5 txog R-6, tab sis cov tshuab hwm zoo ntaus R-20. Peb hlub lawv vim lawv tshem tawm thermal bridging. Thaum tshav kub kub tsis tuaj yeem nkag los ntawm cov khoom siv hluav taws xob. Lawv kuj tawm tsam huab cua hnyav. Koj tsis tshua xav tau repaint los yog kho lawv. Qhov downside? Lawv nqa tus nqi siab dua. Cia siab tias yuav them ntawm $800 thiab $2,500 lossis ntau dua.
Steel Qhov Rooj: Durable thiab nyiaj txiag-phooj ywg
Cov qhov rooj hlau muaj qhov sib npaug zoo heev. Cov neeg tsim khoom tsim lawv siv cov tawv tawv tawv qhwv ib ncig ntawm polyurethane ua npuas ncauj rwb thaiv tsev tub ntxhais. Lawv feem ntau suav nrog cov huab cua sib nqus. Nws tsim lub foob kaw ntom nti, zoo li koj lub qhov rooj tub yees. Peb txaus siab rau lawv cov kev ruaj ntseg zoo heev thiab tus nqi nruab nrab. Lawv feem ntau raug nqi ntawm $300 thiab $1,200. Lawv muab cov rwb thaiv tsev zoo, thiab. Txawm li cas los, lawv muaj ib co drawbacks. Hlau ua qhov kub thiab txias, yog li thermal bridging tuaj yeem tshwm sim. Thaum tshav kub kub yuav khiav los ntawm cov hlau ncej. Lawv kuj dents yooj yim thiab tuaj yeem xeb nyob rau hauv ib puag ncig ntug hiav txwv.
Ntoo Qhov Rooj: Classic Beauty and Thermal Drawbacks
Tsis muaj leej twg tuaj yeem tsis lees paub lub ntuj zoo nkauj ntoo qhov rooj muab. Lawv saib elegant thiab muaj kev txom customization xaiv. Yog tias lawv raug kev puas tsuaj, koj tuaj yeem kho tau yooj yim lossis rov kho lawv. Tab sis yuav ua li cas lawv ua thermally? Khoom ntoo muaj kev rwb thaiv tsev tsis zoo. Lawv feem ntau tau qhab nia U-Factor ntawm 0.50 lossis siab dua. Piv nrog rau cov kev xaiv niaj hnub no, lawv cia cua sov khiav ceev ceev. Lawv kuj xav tau kev saib xyuas siab. Koj yuav tsum muab khi thiab pleev xim rau lawv tsis tu ncua. Yog tias koj tsis quav ntsej lawv, lawv raug kev puas tsuaj rau huab cua. Cov av noo ua rau lawv nthuav dav thiab cog lus, rhuav tshem lawv cov foob.
| Cov khoom siv | rwb thaiv tsev zoo | Tus nqi Tus nqi tseem ceeb | tsis zoo |
|---|---|---|---|
| Fiberglass | Zoo heev (R-20) | $800 - $2,500+ | Tus nqi siab dua |
