1. I. Lub suab ua rau pem teb, thiab yog vim li cas feem ntau nws tsis yog pem teb qhov txhaum
2. II. Qhov ntom ntom ua ntej: Vim li cas lub pob zeb hauv SPC Ua Dab Tsi Ntoo thiab Laminate tsis tuaj yeem
3. III. Lub hauv paus yog ib nrab teb, thiab Nws yog ib nrab feem ntau installation tau yuam kev
4. IV. Tight Seams, Tsawg Txoj Kev
5. V. SPC tiv thaiv laminate, Hardwood, thiab pobzeb: Qhov twg nws yeej thiab dab tsi tus lej hais tiag

Lub suab nrov hauv pem teb yog ob qhov teeb meem sib txawv uas qhia lub npe. Thawj yog cov suab nrov nrov: lub suab ntawm tus hneev taw, ib qho khoom poob, lossis lub rooj zaum rub tawm thoob plaws qhov chaw, kis los ntawm kev sib dhos hauv pem teb mus rau hauv chav hauv qab no. Qhov thib ob yog lub suab nrov: lub suab ntawm lub suab, lub suab TV, lossis cov khoom siv hum dhia tawm hauv pem teb thiab nyob hauv chav. SPC flooring nyob rau ob qho tib si, tab sis los ntawm cov txheej txheem sib txawv thiab rau qib sib txawv. Lub pob zeb ntom ntom - yas core attenuates cuam tshuam kev sib kis. Qhov kev ntxhib los mos thiab cov underlayment kov kev xav thiab ntxiv dampen dab tsi cov tub ntxhais tsis nres.

Kab lus no sib piv cov suab nrov ntawm cov tub ntxhais hluas yas flooring tiv thaiv laminate, hardwood, ceramic pobzeb, thiab khoom kim heev vinyl pobzeb thoob plaws ob qho tib si cuam tshuam thiab qhov ntev. Nws kuj tseem hais txog lub luag haujlwm ntawm kev xaiv underlayment, uas tseem ceeb npaum li lub suab zoo li lub plank nws tus kheej, thiab kev koom tes ntawm kev nias - kaw qhov sib koom ua ke kaw txoj hauv kev uas lub suab nrov siv los taug kev hauv pem teb. Rau SPC flooring nrog cov ntaub ntawv acoustic specifications thiab tau tshaj underlayment xaiv, lubrigid core vinyl flooring ntau yammuab cov ntaub ntawv qhia txog kev cuam tshuam cov chav kawm thaiv kev ntsuas thiab underlayment compatibility ib cov khoom kab.

Thaum ib tug neeg taug kev hla ib chav tsev sab sauv - thiab tus neeg hauv qab no hnov ​​​​txhua tus hneev taw, lub tswv yim yog los liam cov khoom hauv pem teb. Ib lub laminate pem teb suab nrov. Ib tug hardwood pem teb suab nrov. Pobzeb suab nrov tshaj plaws. Cov qauv zoo li meej thiab nws taw qhia rau cov khoom siv saum npoo raws li qhov chaw ntawm qhov teeb meem. Tus qauv yog yuam kev. Dab tsi tus neeg hauv qab no hnov ​​​​txog cov suab nrov uas kis tau los ntawm kev sib dhos hauv pem teb: cov khoom siv hauv pem teb, cov hauv qab, cov subfloor, cov joists, thiab cov kab noj hniav hauv qab. Cov khoom siv saum npoo yog ib txheej hauv ntau - txheej txheej. Hloov cov khoom siv saum npoo yam tsis hloov dab tsi hauv qab no ua rau muaj kev txhim kho me dua li cov neeg feem coob xav tau.

Cov metric uas ntsuas qhov cuam tshuam lub suab kis tau tus mob yog Impact Insulation Class, lossis IIC. Nws yog ib lub chaw soj nstuam- kev ntsuas ntsuas uas ntsuas qhov zoo hauv pem teb - lub qab nthab sib dhos ua kom lub suab ntawm lub tshuab tapping tus qauv poob rau hauv pem teb. Kev ntsuas IIC siab dua txhais tau hais tias tsis tshua muaj suab nrov mus txog chav hauv qab no. Ib lub pob zeb liab qab uas tsis muaj hauv pem teb yuav tau qhab nia IIC ntawm 25. Cov slab tib yam nrog SPC pem teb thiab cov acoustic underlayment zoo tuaj yeem ncav cuag IIC ntawm 55 lossis siab dua, uas ua tau raws li lossis ntau tshaj qhov yuav tsum tau ua hauv tsev rau ntau- tsev neeg kev tsim kho nyob rau hauv feem ntau jurisdictions. Qhov kev txhim kho yog los ntawm kev sib dhos, tsis yog los ntawm cov ntoo ib leeg. Lub 4-millimeter SPC plank uas tsis muaj underlayment ntawm lub pob zeb pob zeb ntxiv me ntsis rau IIC. Tib lub phiaj xwm ntawm 2 millimeters ntawm cov roj hmab ntom ntom ntxiv ntxiv 10 mus rau 15 cov ntsiab lus. Lub underlayment ua qhov hnyav lifting rau cov suab nrov. Lub plank txoj kev pab yog tiag tiag tab sis thib ob.

Reflected suab nrov nyob rau hauv chav tsev yog lwm ib nrab ntawm cov duab acoustic, thiab ntawm no cov flooring nto tseem ceeb dua. Ib qho tawv, du nto zoo li cov pobzeb polished lossis glossy hardwood qhia txog yuav luag txhua lub suab zog uas ntaus nws. Chav tsev suab kaj thiab nyob. Ib qho chaw nrog me ntsis kev ntxhib los mos, zoo li cov nplej embossed ntawm SPC plank, tawg qee qhov ntawm lub zog ntau dua li tsis xav txog nws coherently, thiab cov tub ntxhais ntom ntom absorbs ib feem ntawm qhov cuam tshuam lub zog ntawm qhov chaw sib cuag. Qhov txawv yog ntsuas tau nyob rau hauv lub sij hawm reverberation tab sis pom ntau dua nyob rau hauv subjective kev nplij siab. Ib chav nrog SPC flooring suab qis dua li tib chav nrog cov pobzeb ceramic, txawm tias tsis muaj rooj tog lossis cov rooj tog muag muag kom nqus suab. Kev txhim kho yog me ntsis. Nws tsis yog kev xav. Rau qhov chaw uas ob qho tib si cuam tshuam kev sib cais thiab chav acoustics teeb meem, tag nrhoSPC flooring catalogteev IIC thiab cov ntaub ntawv xa tawm suab ib yam khoom thiab kev sib xyaw ua ke.

SPC flooring yog kwv yees li 60 mus rau 75 feem pua ​​​​calcium carbonate los ntawm qhov hnyav. Qhov seem seem yog PVC cob thiab ua cov khoom siv ntxiv. Qhov tshwm sim yog ib tug plank nrog ib tug ceev ntawm kwv yees li 1,900 mus rau 2,100 kilograms ib cubic meter. Rau kev sib piv, siab - ntom fiberboard, cov khoom tseem ceeb hauv laminate flooring, khiav li 800 mus rau 900 kilograms ib cubic meter. Cov ntoo tawv tawv, nyob ntawm hom, thaj tsam ntawm 600 txog 900 kilograms ib cubic meter. SPC core yog ntau tshaj ob zaug li tuab li cov tub ntxhais ntawm lub laminate plank ntawm tib lub thickness. Nws yog denser dua ntoo qhib, denser dua maple, thiab denser dua tej ntoo-raws li cov khoom flooring nyob rau hauv lub lag luam luv luv ntawm engineered xyoob.

Density matters for sound because sound transmission through a solid material is governed by the impedance of the material. Qhov ceev dua txhais tau tias siab dua acoustic impedance, uas txhais tau hais tias ntau lub zog suab yog xav txog ntawm qhov sib cuam tshuam ntawm cov khoom thiab cov huab cua, thiab tsawg zog nkag mus rau hauv cov khoom kom kis tau los ntawm nws. Ib tug hneev taw ntawm qhov ntom ntom ua rau lub suab nthwv dej uas ntsib qhov siab -impedance barrier tam sim ntawd, thiab ib feem tseem ceeb ntawm lub zog tau rov qab los rau hauv chav tsev es tsis xa mus rau hauv subfloor. Lub pob zeb nyob rau hauv SPC core tsis absorbing suab li ib tug ntxeem tau acoustic vaj huam sib luag absorbs airborne suab. Nws yog thaiv nws, txoj kev hnyav qhov rooj thaiv kev sib tham los ntawm chav tom ntej. Lub mechanism yog loj, tsis porosity. Lub pob zeb- cov khoom sib xyaw yas yog hnyav rau nws cov tuab, thiab qhov hnyav ua haujlwm acoustic uas cov khoom sib dua nrog tib lub thickness yuav tsis ua tiav.

Muaj kev lag luam tawm - tawm hauv qhov txheej txheem no. SPC flooring yog nruj. Nws tsis flex underfoot txoj kev cushioned vinyl ntawv hauv pem teb flexes, thiab nws tsis nqus lub zog los ntawm deformation txoj kev ntaub pua plag absorbs nws. Lub rigidity uas ua rau SPC dimensionally ruaj khov nyob rau hauv qhov kub thiab txias hloov yog tib yam rigidity uas txwv ntau npaum li cas cuam tshuam lub zog lub plank nws tus kheej yuav dissipate. Lub pob taws tawm tsam ntawm SPC pem teb hloov ntau lub zog mus rau hauv lub hauv paus thiab subfloor dua li tib lub pob taws tawm tsam ntawm cov ntaub pua plag hauv pem teb, uas absorbs qhov cuam tshuam hauv pawg thiab lub ncoo. SPC txo cov suab nrov piv rau lwm cov ntaub ntawv nyuaj hauv pem teb. Nws tsis txo suab nrov piv rau cov ntaub pua plag. Tsis muaj qhov nyuaj saum npoo av ua. Kev sib piv acoustic uas tseem ceeb yog SPC piv rau laminate, hardwood, thiab pobzeb. Thoob plaws hauv daim teb, qhov ntom ntom yog qhov sib txawv uas muab SPC ntug.

Lub underlayment hauv qab SPC pem teb yog ib qho acoustic tivthaiv ua ntej thiab cushioning txheej thib ob. Qhov sib txawv yog qhov tseem ceeb vim tias ob txoj haujlwm rub tawm qhov sib txawv. Ib tug tuab, mos ua npuas ncauj underlayment xis nyob rau hauv qab thiab yog pheej yig mus yuav. Nws kuj compresses nyob rau hauv qhov hnyav ntawm ib tug neeg taug kev hla nws, thiab qhov compression tsim ntsug txav ntawm qhov nias - xauv pob qij txha nrog txhua tus taw. Nyob rau lub asthiv thiab hli, qhov rov ua dua micro- txav ntawm cov pob qij txha, tsim qhov khoob, thiab thaum kawg ua rau hauv pem teb tsis ua haujlwm ntawm cov seams. SPC flooring manufacturers qhia underlayment nrog qhov siab tshaj plaws compression ntsuam xyuas, thiab tshaj qhov kev ntsuam xyuas kom tau txais acoustic kev ua tau zoo fij cov qauv kev ncaj ncees ntawm cov pob qij txha. Qhov zoo tshaj plaws underlayment uas rhuav tshem hauv pem teb tsis yog ib qho zoo underlayment.

Peb cov ntaub ntawv underlayment dominate lub acoustic SPC flooring lag luam, txhua tus muaj qhov sib npaug ntawm lub suab, compression resistance, thiab nqi. Cork underlayment yog cov khoom siv ntuj tsim nrog cov qauv cellular uas dissipates suab zog los ntawm kev sib txhuam sab hauv hauv cov phab ntsa ntawm tes. Nws tiv taus compression zoo-cork rov qab nws cov tuab tom qab thauj khoom zoo dua li cov khoom siv hluavtaws feem ntau- thiab nws ntxiv kwv yees li 8 mus rau 12 cov ntsiab lus rau IIC kev ntsuam xyuas ntawm lub rooj sib txoos hauv pem teb ntawm lub thickness ntawm 2 mus rau 3 millimeters. Nws yog qhov kev xaiv zoo rau kev teeb tsa vaj tse nyob qhov twg kev ruaj ntseg tseem ceeb thiab lub hom phiaj acoustic yog nruab nrab. Rubber underlayment, feem ntau yog ua los ntawm cov log tsheb rov ua dua los yog hluavtaws elastomer, yog denser dua cork thiab muab cov txiaj ntsig IIC siab dua, feem ntau 12 txog 18 cov ntsiab lus, ntawm qhov sib npaug thicknesses. Nws yog tus qauv kev xaiv rau kev lag luam thiab ntau- tsev neeg kev teeb tsa uas cuam tshuam cov suab nrov cais tawm thiab cov peev nyiaj tso cai rau cov khoom siv zoo. Tshwj xeeb soundproof underlayments, uas ua ke ib tug tuab tuab -loaded txheej nrog ib tug decoupling ua npuas ncauj los yog fiber ntau txheej, ua tau lub siab tshaj plaws IIC kev ntsuam xyuas-20 cov ntsiab lus los yog ntau tshaj saum toj no liab qab slab-tab sis ntawm tus nqi uas ua rau lawv cov tswv yim feem ntau rau siab -kawg lub tsev nyob thiab cov khoom kim heev uas muaj ntau yam kev ua tau zoo.

Ib qeb plaub muaj tab sis ua haujlwm txawv. Cov dej ntub dej hauv qab nrog ib qho ua tau - nyob rau hauv vapor barrier yog xav tau rau kev teeb tsa ntawm cov pob zeb ua vaj tse, qhov twg cov av noo noo txav mus los ntawm cov slab tuaj yeem ua rau hauv pem teb thiab ua rau muaj kev puas tsuaj rau lub sijhawm. Cov dej noo barrier yog acoustic nruab nrab. Nws tsis txhim kho suab ua haujlwm. Nws tsis degrade nws. Nws tiv thaiv hauv pem teb los ua ke, thiab acoustic underlayment, yog tias siv, mus rau sab saum toj ntawm cov dej noo thaiv. Ob txoj haujlwm yog ua tiav thiab cov khaubncaws sab nraud povtseg tau muab tso rau hauv ib ntus, tsis ua ke rau hauv ib qho khoom uas ua rau ob qho tib si tsis zoo. Rau SPC flooring nrog tshaj underlayment specifications, lubcov khoom specificationssuav nrog qhov siab tshaj plaws compression ntsuas thiab pom zoo underlayment hom ib puag ncig kev teeb tsa.

IIC nce qhov txiaj ntsig yog kwv yees thiab nyob ntawm tag nrho hauv pem teb -kev sib dhos qab nthab. Ib qho underlayment uas xa cov +15 IIC cov ntsiab lus ntawm lub pob zeb ua vaj tse yuav ua rau muaj qhov sib txawv ntawm cov ntoo - ncej subfloor. Nco ntsoov xyuas nrog kev sib dhos- cov ntaub ntawv xeem tshwj xeeb.

Lub suab nrov ntawm huab cua mus los ntawm qhov sib txawv nws tuaj yeem pom. Lub rooj sib txoos hauv pem teb nrog qhib seams ntawm planks muab ntau txoj hauv kev me me rau lub suab kom txav los ntawm chav tsev saum toj no mus rau kab noj hniav hauv qab no, hla qhov loj ntawm cov khoom siv hauv pem teb tag nrho. Qhov kev ua tau zoo ntawm acoustic hauv pem teb yog txwv los ntawm nws qhov tsis muaj zog tshaj plaws acoustic txuas, thiab qhov sib txawv ntawm ib feem ntawm ib millimeter yog acoustic deb tsis muaj zog dua li cov ntoo ntawm ob sab ntawm nws. Ib pem teb nrog nruj seams channels suab los ntawm cov khoom siv plank, qhov ntom ntawm cov tub ntxhais ua nws txoj haujlwm. Hauv pem teb nrog xoob seams muab lub suab yooj yim dua, thiab txoj kev yooj yim dua yog lub suab siv.

Qhov nias - xauv qhov sib koom ua ke ntawm SPC flooring nyob qhov no los ntawm kev tsim ib qho kev sib tshuam uas rub cov kab uas nyob ib sab ua ke hauv qhov nro. Cov ntaub ntawv sib koom ua ke yog milled rau hauv cov tub ntxhais nruj thaum lub sijhawm tsim khoom, thiab thaum ob lub phiaj xwm raug nias ua ke, qhov geometry ntawm qhov profile tsim lub zog clamping uas tuav lub seam kaw. Lub seam tsis glued. Nws tsis yog nailed. Nws raug kaw los ntawm cov duab ntawm cov khoom siv nws tus kheej, thiab nws nyob twj ywm kaw ntev li ntev raws li hauv pem teb tau teeb tsa nrog qhov tseeb nthuav dav ntawm qhov ib puag ncig kom tiv thaiv tag nrho hauv pem teb ntab los ntawm kev hloov pauv raws li chav tsev. Ib qho yooj yim ntsia tau nyem-lock SPC pem teb muaj seams uas ua haujlwm airtight, thiab airtight seams kuj yog suab-nruj rau cov zaus uas tseem ceeb hauv chav- mus rau-chav xa mus.

Qhov no yog qhov zoo ntawm cov qauv uas SPC sib koom nrog cov laminate thiab engineered ntoo, ob qho tib si kuj siv nias -lock sib koom ua ke. Qhov kom zoo dua ntawm cov kua nplaum- nqes khoom kim heev vinyl pobzeb yog ntau tshaj li qhov zoo dua lwm yam nyem - xauv khoom. Glue-down LVT cia siab rau tag nrho -paj nplaum daim ntawv cog lus los tuav txhua daim phiaj lossis pobzeb rau hauv subfloor, thiab cov seams nruab nrab ntawm cov khoom tsis raug kaw. Lawv cia siab rau cov nplaum los tuav cov npoo ntawm kev sib cuag. Thaum lub sij hawm, raws li lub hnub nyoog ntawm cov nplaum thiab cov subfloor txav mus, micro- qhov khoob tuaj yeem qhib ntawm ntug seam, thiab cov micro- qhov khoob no dhau los ua acoustic leaks. Nyem-lock SPC tsis cia siab rau cov nplaum rau seam kev ncaj ncees. Qhov sib koom ua ke yog ib qho kev sib cuam tshuam lub cev uas tsis degrade nrog lub hnub nyoog ntawm txoj kev adhesive bond degrades. Rau ntev -lub sij hawm acoustic sib xws nyob rau hauv lub neej ntawm lub hauv pem teb, cov neeg kho tshuab sib koom ua ke muaj qhov zoo tshaj plaws ntawm cov tshuaj sib tov.

Kev sib piv cov suab nrov ntawm cov khoom siv hauv pem teb yuav tsum tau muab piv rau tag nrho cov khoom sib dhos, tsis yog txheej txheej saum npoo ib leeg, vim tias lub rooj sib txoos txiav txim siab qhov tshwm sim ntawm acoustic. Qhov kev sib piv hauv qab no suav tias yog tus qauv hauv tsev ntoo -thav duab subfloor nrog tib lub hauv qab ntawm txhua yam khoom siv, uas cais cov kev koom tes ntawm cov khoom hauv pem teb nws tus kheej. Hauv kev xyaum, kev xaiv underlayment feem ntau txawv los ntawm hom flooring, thiab qhov tiag -lub ntiaj teb acoustic txawv ntawm ob cov ntaub ntawv tuaj yeem loj lossis me dua cov khoom siv-tsuas yog kev sib piv qhia nyob ntawm seb qhov twg tau teeb tsa hauv qab lawv.

SPC tiv thaiv laminate.Ob qho khoom siv siv ib qho nias -lock floating installation hla underlayment. Qhov sib txawv ntawm acoustic feem ntau yog kev ua haujlwm ntawm qhov ntom ntom. SPC, ntawm kwv yees li ob zaug ntawm qhov ceev ntawm laminate HDF core, muab ntau qhov cuam tshuam lub suab attenuation ntawm lub plank theem ua ntej lub suab nthwv dej mus txog hauv qab. Qhov sib txawv ntawm IIC kev ntsuam xyuas ntawm SPC thiab laminate tshaj tib lub hauv qab yog feem ntau 2 mus rau 5 cov ntsiab lus hauv qhov kev pom zoo ntawm SPC, uas yog qhov pom tau tab sis tsis txaus ntseeg. Qhov sib txawv tseem ceeb tshaj plaws yog lub suab hauv chav. Laminate flooring ua rau hollow, nruas-zoo li footfall suab vim HDF core resonates ntawm nruab nrab-frequencies thaum ntaus. SPC tsim lub suab nrov nrov, luv luv vim tias lub pob zeb -polymer composite muaj qhov zaus resonance uas siab dua thiab nrawm dua li HDF. Lub suab ntawm kev taug kev ntawm SPC yog ntsiag to rau tus neeg taug kev, txawm tias tus neeg nyob hauv qab yuav hnov ​​​​cov suab nrov zoo sib xws. Both materials benefit enormously from a quality underlayment, and the difference between a cheap foam underlayment and a dense rubber underlayment is larger than the difference between SPC and laminate over the same underlayment.

SPC piv rau hardwood.Cov khoom siv tawv tawv hauv pem teb, thaum ntsia hlau lossis stapled ncaj qha mus rau subfloor, xa cov suab nrov zoo vim tias cov fasteners tsim kom muaj kev sib txuas ntawm cov khoom siv sib txuas ntawm cov flooring thiab subfloor. Lub zog cuam tshuam mus los ntawm cov rau tes rau hauv cov joists nrog tsawg kawg nkaus attenuation. Floating SPC hla ib qho acoustic underlayment decouples hauv pem teb nto los ntawm subfloor, thiab qhov decoupling yog lub luag haujlwm rau feem ntau ntawm kev txhim kho acoustic. Qhov sib txawv IIC ntawm nailed hardwood thiab floating SPC nrog cov roj hmab underlayment tuaj yeem yog 15 mus rau 25 cov ntsiab lus, uas yog qhov sib txawv ntawm ib pem teb uas tsim cov kev tsis txaus siab los ntawm chav tsev hauv qab no thiab hauv pem teb uas ua tau raws li ntau- tsev neeg cov cai. Engineered hardwood ntsia raws li ib tug floating pem teb nrog ib tug underlayment nqaim qhov sib txawv considerably, txo cov SPC kom zoo dua rau 3 mus rau 8 IIC cov ntsiab lus, zoo ib yam li cov laminate sib piv. Qhov kom zoo dua ntawm acoustic SPC tshaj hardwood yog feem ntau yog ib qho yooj yim installation txoj kev kom zoo dua, tsis yog cov khoom kom zoo dua. Floating floors cais zoo dua li cov plag tsev fastened tsis hais cov khoom siv.

SPC piv rau ceramic lossis porcelain pobzeb.Pobzeb yog cov khoom nrov tshaj plaws ntawm cov khoom siv hauv pem teb. Nws yog ntsia nrog thinset mortar ncaj qha mus rau lub cement board los yog qhob substrate, tsim kom muaj ib tug nruj, siab - ceev sib dhos uas tsis muaj decoupling txheej thiab tsis muaj underlayment. Kev cuam tshuam lub suab nrov tawm ntawm cov pobzeb saum npoo los ntawm cov tshuaj khib rau hauv cov substrate uas yuav luag tsis muaj kev cuam tshuam ntawm qib flooring. Qhov saum npoo yog tawv thiab muaj kev cuam tshuam, yog li cov suab nrov hauv huab cua hauv chav bounces tawm nws nrog tsawg kawg nkaus nqus. SPC dhau ntawm acoustic underlayment outperforms pobzeb rau kev cuam tshuam lub suab nrov los ntawm 20 mus rau 30 IIC cov ntsiab lus, qhov sib txawv loj tshaj plaws nyob rau hauv ib qho nyuaj saum npoo av sib piv. Nyob rau hauv lub chav tsev, textured nto ntawm ib tug SPC plank absorbs thiab scatters ntau reflected suab tshaj ib tug glazed pobzeb nto, txo cov perceived brightness ntawm chav tsev. Pobzeb, txawm li cas los xij, muaj ib qho txiaj ntsig zoo: nws tsis resonate. Ib qho khoom poob rau ntawm pobzeb ua rau lub suab nrov, luv luv uas nres yuav luag tam sim ntawd. Ib qho khoom poob rau hauv pem teb ntab tuaj yeem ua rau luv luv resonant lwj raws li lub hauv paus sib dhos vibrates. Lub resonance yog hloov maj mam thiab feem ntau cov neeg nyob hauv yeej tsis pom nws. Nws yog ntsuas tau, thiab nws tsuas yog acoustic qhov ntev uas cov pobzeb ua tau zoo tshaj hauv pem teb ntab nrog cov tub ntxhais ntom ntom.

SPC flooring txo cov suab nrov piv rau lwm cov ntaub ntawv nyuaj hauv pem teb los ntawm peb lub tshuab uas ua haujlwm ntawm cov ntsiab lus sib txawv hauv txoj kev xa suab. Lub pob zeb ntom ntom -polymer core muab ntau qhov hnyav ib millimeter ntawm tuab dua li laminate, hardwood, los yog LVT, thiab qhov loj ntawd txo cov suab nrov ntawm qhov chaw sib cuag ua ntej lub zog mus txog hauv qab. Qhov nias - kaw qhov sib koom ua ke kaw cov seams ntawm cov phiaj xwm, tshem tawm cov micro- qhov khoob uas cov suab nrov hauv huab cua siv los hla cov huab cua hauv av. Lub underlayment, uas yog ib tug nyias muaj nyias ib yam khoom xaiv kom phim lub acoustic yuav tsum tau ntawm lub installation, decouples lub floating pem teb los ntawm subfloor thiab absorbs lub zog cuam tshuam uas lub plank tsis nres. Peb lub tshuab ua haujlwm ua ke, thiab qhov tshwm sim acoustic nyob ntawm txhua qhov peb tau raug teev thiab teeb tsa.

Ib qho kev sib txawv loj tshaj plaws hauv kev ua yeeb yam ntawm SPC pem teb tsis yog cov ntoo. Nws yog underlayment. Ib tug hwm SPC plank tshaj ib tug pheej yig ua npuas ncauj underlayment yuav underperform ib tug qauv SPC plank tshaj ib tug tuab roj hmab underlayment los ntawm ib tug margin uas yog ob qho tib si ntsuas thiab audible. Yog hais tias lub suab nrov txo qhov teeb meem, faib cov pob nyiaj siv acoustic rau cov txheej txheem uas ua haujlwm acoustic. Lub plank muab rau pem teb koj pom thiab taug kev. Lub underlayment muab qhov ntsiag to uas chav hauv qab no hnov. Ob leeg tseem ceeb. Tsuas yog ib qho pom xwb. Ib qho uas tsis pom yog qhov uas txiav txim siab seb lub hauv paus puas nyob ntsiag to.
