Most building codes accept PVC profiles that meet established standards like ASTM D4726 and AAMA specifications. Fire codes may restrict use in specific applications like fire-rated assemblies, though flame-retardant formulations address many concerns. Always verify local code requirements with building authorities, as jurisdictions occasionally maintain specific restrictions or approval processes.
Yuav ua li cas PVC profiles piv tus nqi - ntse rau lwm txoj kev?
Tus nqi pib ntawm cov khoom siv feem ntau poob ntawm cov ntoo thiab txhuas. Txawm li cas los xij, kev txheeb xyuas tus nqi ntawm lub neej- suav nrog kev teeb tsa kev ua haujlwm, kev ua haujlwm ntawm lub zog, kev saib xyuas, thiab kev hloov pauv- feem ntau nyiam PVC ntau heev. Kev txuag hluav taws xob ib leeg feem ntau rov qab tau cov nqi pib ua ntej hauv 5-10 xyoo, nrog kev txuag nyiaj ntxiv thoob plaws hauv 40-60 xyoo kev pabcuam.
Puas yog PVC profiles puas tuaj yeem kho tau?
Kev puas tsuaj me me feem ntau kho los ntawm sanding thiab refinishing. Cov qauv kev puas tsuaj feem ntau yuav tsum tau hloov seem, txawm hais tias qhov modular xwm ntawm extruded profiles ua rau hloov ncaj qha. Kev sib txuas tshuaj thiab cov thev naus laus zis thev naus laus zis tuaj yeem kho thaj chaw hauv ntau qhov xwm txheej, txawm hais tias kev ntsuam xyuas kev tshaj lij txiav txim siab txog kev kho kom tsim nyog rau cov xwm txheej tshwj xeeb.
Ntsiab Cai
Yas PVC extrusion profiles xa thermal kev ua tau zoo 500-700 lub sij hawm superior rau txhuas lwm yam, ncaj qha txo lub tsev zog noj los ntawm 15-24% nyob rau hauv cov ntaub ntawv installation
Kev pab cuam lub neej kwv yees ntawm 40-60 xyoo nrog kev saib xyuas tsawg kawg tsim kev lag luam kev lag luam zoo piv rau cov ntoo, txhuas, thiab hlau lwm yam uas yuav tsum tau kho tsis tu ncua thiab hloov ua ntej.
Ntau-chamber profile tsim, kev xaiv kev txhawb nqa sab hauv, thiab ntau cov qauv tsim kom muaj kev hloov kho rau cov ntawv thov tshwj xeeb hauv tsev los ntawm cov qhov rais vaj tsev mus rau qhov rooj ua haujlwm
Kev teeb tsa kom raug raws li cov chaw tsim khoom tshwj xeeb thiab cov qauv kev lag luam ua pov thawj qhov tseem ceeb-73% ntawm PVC profile tsis ua haujlwm taug qab rau kev teeb tsa tsis raug ntau dua li cov khoom siv tsis raug.
Environmental kev ua tau zoo zoo tshwm sim feem ntau thaum lub sij hawm ua hauj lwm theem, qhov superior thermal rwb thaiv tsev txo HVAC zog noj uas dominates lub tsev lifecycle ib puag ncig cuam tshuam.
