- Amaphepha okukhupha umoya e-VOC kuphela awasaneliseki zimvume ze-façade zehotele ezinezitezi ezininzi; ingxelo yovavanyo lomlilo esebenzayo ngokwe-EN 13501-1 ngoku iyafuneka.
1. Kutheni iiFacades zeHotele ziphantsi kweMicroscope eLawulayo
Intlekele yeGrenfell Tower ngo-2017 yabangela utshintsho olukhulu kwindlela abalawuli baseYurophu abavavanya ngayo izinto ezikwizakhiwo zikawonke-wonke nezeendwendwe. Kwiminyaka ukususela ngoko, Ulawulo lweeMveliso zoKwakha ze-EU (CPR) ihlaziyiwe, kwaye imithetho yokwakha yamalungu karhulumente ilandele iimfuno zasekuhlaleni eziqinileyo.
Iihotele zijongene nokuhlolwa okukhethekileyo ngenxa yezizathu ezintathu:
- Uxinano lwabahlali: Ihotele ephakathi nendawo inokwamkela iindwendwe ezininzi kumgangatho ngamnye ngexesha lexesha elixakekileyo. Ixesha lokuphuma lilinganiswa ngemizuzu, hayi imizuzwana.
- Ukuhlala ubusuku bonke: Abantu abaninzi abahlala apho balele xa umngcipheko womlilo uphezulu, nto leyo ecothisa ukusabela kokuqala.
- Ukusasazwa komlilo othe nkqo: I-façade cladding isebenza njengetshimini ukuba ayikwazi ukumelana nokwanda komlilo, ikhawulezisa ukusasazeka ngokuthe nkqo kwimigangatho emininzi.
Ngenxa yezi zizathu, amagunya kazwelonke eFransi (Reglementation Sécurité Incendie), eJamani (Landesbauordnungen), eNetherlands (Bouwbesluit 2012 izilungiso), kunye nabanye ngoku babhekisa ngokucacileyo EN 13501-1: Uhlu lomlilo lweemveliso zokwakha njengomlinganiselo wokwamkelwa kwezinto ezifakelwe ubuso kwiihotele nakwizakhiwo ezifanayo.
2. Ukuqonda i-EN 13501-1: Oko Kuthethwa Yindlela Yokwahlulahlula
EN 13501-1 ihlela iimveliso zokwakha kwiiklasi ze-Euro ukusuka kwi-A1 (ezingatshiyo) ukuya kwi-F (akukho ntsebenzo imiselweyo). Inkqubo yokwahlulahlula ivavanya iikhrayitheriya ezintathu ngaxeshanye:
| Ikhrayitheriya | Oko Kukulinganisayo | Umgangatho woVavanyo |
|---|---|---|
| Ukungatshiseki | Ingaba imveliso iyavutha na xa ivezwe kwilangatye elincinci | I-EN ISO 11925-2 |
| Ukukhululwa kobushushu | Izinga lokukhululwa kobushushu obuphezulu (i-FIGRA) kunye nobushushu obupheleleyo obukhutshwayo | I-EN ISO 9239-1 (yomgangatho) |
| Imveliso yomsi | Izinga kunye nomthamo opheleleyo womsi owenziweyo | I-EN ISO 9239-1 (yomgangatho) |
Kwizicelo zomgangatho kunye ne-façade, olu didi lusebenzisa isimamva esithi "fl" (umgangatho) kwindlela yovavanyo lwe-single-burning-item (SBI) elungiselelwe iimveliso zomphezulu. Iiklasi eziphambili ezifanelekileyo kwi-WPC cladding zezi:
- Afl: Ayitshi (ikhonkrithi, ilitye). Ayinakufezekiswa yi-WPC.
- I-Bfl-s1: Igalelo elincinane kakhulu emlilweni kwaye imveliso yomsi iphantsi kakhulu. Udidi oluphezulu olunokufunyanwa zizinto ezitshayo.
- I-Cfl-s1 / I-Cfl-s2: Igalelo elincinci xa umsi uphantsi okanye uphakathi.
- I-Dfl / Efl: Ukusebenza okwamkelekileyo okanye okungaphantsi; ukungamkeleki ngakumbi ngenxa yeefestile zeehotele ezinezitezi ezininzi.
Uhlobo lwe-"s1" lomsi lubalulekile kwiihotele. Ukuphefumla umsi yeyona nto iphambili ebangela ukufa kwimililo yezakhiwo. Uvavanyo lwe-s1 luqinisekisa ukuba imveliso yomsi ihlala ingaphantsi kwama-30 m²/s kwinqanaba lokukhula kwasekuqaleni, nto leyo enika iindwendwe kunye nabaphenduli bexesha likaxakeka ithuba elibanzi lokhuseleko.
3. I-Bfl-s1 vs. Cfl vs. Dfl: Oko Kuthethwa Ziireyithingi zeProjekthi yeHotele
Ukukhetha udidi lomlilo olungalunganga kwi-façade yehotele. Ukugquma kwe-WPC kunemiphumo emithathu ekhawulezileyo xa kusenziwa:
Ukulibaziseka kokuVunywa
Amagunya emvume yokwakha kwiindawo ezininzi ze-EU aza kugatya okanye abambe izicelo ezingenayo ingxelo yovavanyo lwe-EN 13501-1 esebenzayo yodidi oluchaziweyo lomlilo. Ukungenisa isatifikethi se-VOC endaweni yoko kubangela isicelo solwazi esinokongeza iiveki ezi-4-8 kumgca wexesha lokuvunywa.
Iimpembelelo ze-inshurensi
Abanini-inshorensi bepropathi zorhwebo bafuna i-Bfl-s1 okanye ngaphezulu kwizinto ezikwizakhiwo zokwamkela iindwendwe. Umnini-polisi osebenzisa i-Dfl-rated cladding unokujongana nokungabandakanywa kwizimangalo zomonakalo womlilo okanye iiprimiyamu eziphezulu kakhulu.
Umngcipheko woDumo
Iimpawu zeehotele ezisebenza phantsi kweeflegi zamazwe ngamazwe (i-Accor, iMarriott, iHilton) zinemigangatho yokhuseleko lwangaphakathi edla ngokugqitha imigaqo yokwakha yasekuhlaleni. Umphuhlisi ochaza i-cladding engaphantsi komgangatho usengozini yokulahlekelwa yi-franchise yophawu.
Ngenxa yezi zizathu zintathu, i-Bfl-s1 ngoku ithathwa njengowona msebenzi uphantsi wokufakwa kwe-WPC ehotele kwiimarike ezininzi zaseYurophu, nokuba iikhowudi zasekuhlaleni zivumela i-Cfl-s1.
4. Indlela iTekhnoloji ye-Co-Extrusion WPC eyiphumeza ngayo i-Bfl-s1
Iiprofayili ezidityanisiweyo zomthi-plastiki eziqhelekileyo ezingenazo izongezo ezenziwe ngomlilo zihlala zifikelela kumazinga e-Cfl okanye e-Dfl. Ifomyula esisiseko -- i-polyethylene okanye i-polypropylene edityaniswe nomgubo womthi -- inokutsha ngokwemvelo. Ukufikelela kwi-Bfl-s1 kufuna utshintsho olujoliswe kuyo kumanqanaba ezinto kunye nawokuvelisa.
Yanamhlanje i-co-extrusion WPC cladding isebenzisa indlela eneeleya ezimbini:
- Umaleko ongundoqo: I-substrate enkulu ye-WPC idityaniswe nezizalisi ezithintela umlilo zeminerali (i-aluminium trihydrate, i-magnesium hydroxide) ezikhupha umphunga wamanzi xa zifudunyezwa, zifunxa amandla kwaye zicinezele ukusasazeka komlilo.
- Iqokobhe elikhutshiweyo kunye: Umaleko wesigqubuthelo sepolymer okhuselayo ukhutshwa ngaxeshanye phezu kombindi. Esi sigqubuthelo sinokubandakanya izongezo ezingaphakathi ezikhula xa zichatshazelwa bubushushu, zenze umqobo okhusela umbindi ekutshisweni.
Inkqubo yokukhupha kunye iqinisekisa ukuba izongezo ezithintela umlilo zisasazwa ngokuchanekileyo kulo lonke icala leprofayili, endaweni yokuba zisetyenziswe njengengubo yomphezulu enokonakala. Le yinzuzo ebalulekileyo kwizicelo zangaphandle zefaçade apho izinto kufuneka zigcine ukusebenza kwazo komlilo kwiminyaka eli-15-25 yokuguquka kwemozulu.
Ngokuphikisana, i-WPC cladding yakudala Iiprofayili ezingenayo i-co-extrusion zisenokufumana amanqaku omlilo amkelekileyo kwizicelo eziphantsi okanye ezingezizo zehotele, kodwa zihlala zihlala kwi-Cfl-s2 endaweni ye-Bfl-s1.
5. Umgibe Wokuthobela Imithetho ye-VOC Kuphela: Kutheni Amaphepha Okukhupha Inkunkuma EngengoMlilo?
Abaphathi abaninzi beeprojekthi, ingakumbi abo batshintsha ukusuka ekuthengeni izinto zangaphakathi, badibanisa amaxwebhu okukhupha umbane e-VOC (Volatile Organic Compound) kunye nokuthobela imithetho yokhuseleko lomlilo. Oku kudideka kuyaqondakala kodwa kuyingozi.
Iphepha lokukhupha i-VOC lidla ngokubhekisa kwi Imigangatho yochungechunge lwe-ISO 16000 okanye i-EN 16516 kwaye iqinisekisa ukuba imveliso ayikhuphi amanqanaba ayingozi e-formaldehyde, i-benzene, okanye ezinye izinto eziguquguqukayo emoyeni wangaphakathi. Oku kubalulekile ngaphakathi kwigumbi leendwendwe, kodwa akutsho nto malunga noku:
- Ingaba imveliso iya kutsha na xa ivezwe kumthombo womlilo
- Ubungakanani ubushushu obuya kukhutshwa yimveliso xa sele itsha
- Ubungakanani bomsi oza kuveliswa yimveliso ngexesha lokutsha
- Ingaba imveliso iya kuba negalelo ekusasazekeni komlilo kwi-façade
Isatifikethi sokukhupha i-VOC kunye nengxelo yokuhlelwa komlilo ye-EN 13501-1 ngamaxwebhu amabini ahluke ngokupheleleyo avavanya iiparameter ezimbini zokusebenza ezahlukeneyo ngokupheleleyo. Ukungenisa enye endaweni yenye kuya kubangela ukwaliwa kwemvume kuyo yonke imimandla ye-EU ebhekisa kwiimfuno ze-CPR.
Ngowama-2026, amagunya okwakha eJamani, eFransi, eNetherlands, eBelgium, e-Austria naseScandinavia enze iingxelo zokuhlelwa kwe-EN 13501-1 zibe yimfuneko kwiingubo zobuso kuzo zonke izakhiwo zikawonke-wonke ezingaphezu kwemigangatho emibini. Amaphepha e-VOC asenokufuneka kunye neengxelo zomlilo kwizicelo zangaphakathi, kodwa azinakuthatha indawo yokuhlelwa komlilo kwimeko yobuso.
6. Uluhlu lokujonga iinkcukacha ze-Façade WPC Cladding yeHotel Façade
Inkcazo eqinileyo ye-façade yehotele ye-WPC cladding kufuneka iquke ezi mfuno zilandelayo ezinxulumene nomlilo:
| Ipharamitha | Imfuneko | Umgangatho |
|---|---|---|
| Impendulo kumlilo | Ubuncinane be-Bfl-s1 | EN 13501-1 |
| Ingxelo yovavanyo iyasebenza | Ikhutshwe kwisithuba seminyaka emi-5, yi-Notified Body evunyiweyo | I-EU CPR, Inombolo yoBhaliso (i-EU) 305/2011 |
| Ukumelana nemozulu | Ukusebenza komlilo kugcinwa emva kokwaluphala ngokukhawuleza | EN 15534-1, Isihlomelo ZA |
| Ityhefu yomsi | Ngaphantsi komda ngokwesihlomelo sikazwelonke | I-EN ISO 5659-2 |
| Ukumakishwa kwe-CE | Udidi lokusabela kumlilo lubhengezwe kwileyibhile ye-DoP kunye ne-CE | I-EU CPR, Isihlomelo III |
| Umgangatho wemveliso | Ukusebenza kwe-WPC cladding ngokwemigangatho ehambelanayo | EN 15534-1 |
Abathengi kufuneka baqinisekise ukuba ingxelo yovavanyo ibhekisa kulwakhiwo oluthile lwemveliso e-odolwayo -- i-geometry yeprofayili, ubukhulu bodonga, umbala, kunye nokwakheka komaleko we-co-extrusion. Ingxelo yomlilo yeprofayili enobukhulu obuyi-20 mm ayinakwandiswa ibe yinguqulelo enobukhulu obuyi-14 mm, nokuba ifomyula esisiseko iyafana.
Umgangatho wemveliso ohambelanayo EN 15534-1 Ibonelela ngesakhelo sokubhengeza ukusebenza kwe-WPC cladding, kuquka ne-fire reaction, phantsi kwe-CPR. Ukuthobela i-EN 15534 yindlela yokungena kumaki we-CE, nto leyo evumela ukuhamba ngokukhululekileyo kwemveliso kwimarike enye ye-EU.
7. Iindlela zokufakela ezigcina ukusebenza komlilo
Kwanemveliso ye-WPC efakwe i-Bfl-s1-rated WPC inokulahlekelwa yinzuzo yayo yokusebenza komlilo ukuba ifakwe ngendlela engafanelekanga. Iimpazamo eziqhelekileyo zokufakela ezingcolisa ukhuseleko lomlilo ziquka:
- Ulwakhiwo olungaphantsi komgangatho:Ukufaka i-Bfl-s1 Iphaneli yeWpcIsakhiwo esingaphantsi kwebhanti yomthi singenisa izinto ezinokutsha emva komaleko wokugquma. Cacisa iinkqubo ze-aluminium okanye zentsimbi ezingatshiyo zeefaçade zehotele.
- Izithintelo zomngxuma ezingekhoyo: Iifaçades ze-rainscreen ezifakwe umoya zinomngxuma womoya phakathi kwe-cladding nodonga. Ngaphandle kwemiqobo yokuthintela umlilo kumgangatho ngamnye, umlilo ungasasazeka ecaleni nangasecaleni kulo mngxuma. I-EN 1991-1-2 kunye nee-national annexes zichaza indawo yomngxuma.
- Unyango olungafanelekanga lwamalungu: Iijoyinti ezivulekileyo okanye izikhewu ezidlula iinkcukacha zomenzi zinokubeka umbindi weWPC kwindawo ekhokelela ekutshayweni komlilo, zidlule kumaleko okukhusela i-co-extrusion. Landela ububanzi beejoyinti ezichazwe ngumenzi kwaye usebenzise i-sealant elinganiswe ngumlilo apho kuchaziwe khona.
- Ukungena ngaphandle kokucima umlilo: Ukungena kwemibhobho kunye neentambo kwiplani yokugquma kufuneka kuvalwe ngeekhola okanye ii-wraps ezilinganiswe ngomlilo ukugcina umda wegumbi lomlilo.
Uvavanyo lwezinto ze-Bfl-s1 lujongana nemveliso yodwa. Ukusebenza komlilo kwinqanaba lenkqubo -- indibaniselwano ye-cladding, substructure, cavity barriers, kunye ne-perimeter fire stop -- kuvavanywa ngokwahlukeneyo phantsi kwemithetho yesizwe yokwakha kwaye kufuneka kuyilwe yinjineli yomlilo efanelekileyo.
8. Amaxwebhu e-EU CPR: Oko Umele Ukubonelelwe Ngumthengisi Wakho
Ngaphantsi kwe Umgaqo weeMveliso zoLwakhiwo ze-EU (uMmiselo (i-EU) No 305/2011), umenzi obeka i-WPC cladding kwimarike ye-EU kufuneka anikezele:
- Isibhengezo sokuSebenza (i-DoP): Uxwebhu olusemthethweni oluchaza ukusebenza kwemveliso ngokuchasene nophawu ngalunye olubalulekileyo oludweliswe kumgangatho ohambelanayo. Kwisigqubuthelo sefaçade, impendulo kumlilo (udidi lwe-EN 13501-1) luphawu oluyimfuneko olubhengeziweyo.
- Uphawu lwe-CE: Incamatheliswe kwimveliso kunye/okanye kwiphakheji, ebonisa ukuba i-DoP iyafumaneka kwaye imveliso iyahambelana nomgangatho ofanelekileyo ohambelanayo.
- Ingxelo yovavanyo: Ikhutshwe liQumrhu eliNikezelweyo elivunyiweyo (ilebhu eyaziwayo phantsi komgaqo-nkqubo we-CPR). Ingxelo kufuneka ibhekisele kumgangatho othile wovavanyo (i-EN ISO 9239-1 kunye ne-EN ISO 11925-2) kunye nokunikezelwa kwe-Euroclass okubangelwa yiyo.
Amaqela okuthenga afanele acele la maxwebhu ngaphambi kokuba afake iodolo, kungekhona emva kokuba ukuthunyelwa kufikile kwindawo. Ukulungisa amaxwebhu okuthobela umthetho womlilo emva kokuba imveliso sele ifakiwe kwisakhiwo kunzima kakhulu kwaye kubiza kakhulu.
9. Uhlalutyo lweNzuzo-mali: Iiklasi zeBfl-s1 vs. zoMlilo oPhantsi
I-Bfl-s1-rated co-extrusion WPC cladding inexabiso eliphantsi kuneeprofayili ze-Cfl okanye ze-Dfl WPC eziqhelekileyo. Ixabiso eliphantsi libonisa izizalisi zeminerali ezongezelelweyo, izongezo ze-intumescent, kunye neefizi zovavanyo lwe-Notified Body ezifunekayo ukuze kufunyanwe udidi oluphezulu lomlilo.
Nangona kunjalo, ukuvavanya ixabiso kwixabiso lezinto ezibonakalayo kuphela kuyakhohlisa kwiiprojekthi zehotele:
- Vumela ukukhawuleziswa: Ingxelo esebenzayo ye-Bfl-s1 isusa unobangela oqhelekileyo wokulibaziseka kwemvume yokuvunywa kwefacade yehotele, nto leyo enciphisa iindleko zokubamba indawo yophuhliso.
- Ukonga kwiinshorensi: Abanini-inshorensi bepropathi zorhwebo banokubonelela ngeeprimiyamu eziphantsi kwizakhiwo ezineefadesi ezilinganiswe yi-Bfl-s1, behlawula iprimiyamu yezinto ezibonakalayo ngokuyinxenye okanye ngokupheleleyo ngeli xesha lepolisi.
- Ukuthobela uphawu: Iimpawu zeehotele zamazwe ngamazwe zifuna izinto ezifakelwe ubuso ezihlangabezana okanye ezidlula imigangatho yazo yokhuseleko lomlilo lwangaphakathi. Ukuchaza i-Bfl-s1 kwasekuqaleni kukhusela umphuhlisi ekuyilweni ngokutsha okubizayo ukuba umyalelo we-brand usetyenziswa ngexesha lokuhlolwa koyilo.

Umbuzo wabaphuhlisi beehotele awukokuba i-Bfl-s1 ibiza ngaphezulu kune-Cfl na. Umbuzo kukuba ingaba ixabiso lilonke le-Cfl -- kuquka ukulibaziseka kwemvume, iingxaki ze-inshorensi, iingozi zokuthobela imithetho yebhrendi, kunye nokuvezwa koxanduva -- liphantsi kuneprimiyamu yezinto ezibonakalayo ze-Bfl-s1. Kwiimeko ezininzi, akunjalo.
I-WPC Cladding vs. Izinto zeMveli: Uthelekiso loMsebenzi woMlilo kwiiprojekthi zehotele
Xa abakhi bezakhiwo bevavanya izinto zokugquma iifacade zehotele, uthelekiso lokusebenza komlilo phakathi kweWPC kunye nezinye iindlela zemveli ezifana neepaneli ze-aluminium composite, i-laminate enoxinzelelo oluphezulu, kunye nemithi yendalo yeyona nto ithatha isigqibo esihlala simisela iinkcukacha. Iipaneli ze-aluminium composite ezinee-polyethylene cores zasetyenziswa kakhulu ekwakhiweni kweehotele kwiminyaka yoo-2000, kodwa utshintsho lolawulo emva kweGrenfell kulo lonke elaseYurophu luye lwathintela ukusetyenziswa kwazo kwizakhiwo ezingaphezu kweemitha ezili-18. Ukugquma kweWPC nge-EN 13501 Bfl-s1 classification kunika inqanaba lokusebenza komlilo elihlangabezana neemfuno zoMgaqo weeMveliso zoLwakhiwo zaseYurophu kwizakhiwo zazo zonke iindawo eziphakamileyo, ngaphandle kweengxaki zokutsha ezichaphazela iipaneli ze-ACM-PE.
Ukugqunywa kwemithi yendalo kunika ubushushu obuhle obuxatyiswa ngabayili bezakhiwo zehotele, kodwa imithi enganyangwanga idla ngokufezekisa ukusebenza komlilo weklasi ye-D okanye yeklasi ye-C phantsi kwe-EN 13501, nto leyo enganelanga kwiifaçade zehotele kwiindawo ezininzi zaseYurophu. Unyango oluthintela umlilo lunokuphucula imithi ibe yiklasi ye-B, kodwa unyango longeza iindleko, lufuna ukuphinda lusetyenziswe rhoqo, kwaye luzisa umthwalo weekhemikhali ongqubana neemfuno zokukhupha i-VOC ezinyanzeliswa ngakumbi kwiindawo zangaphakathi zehotele. Ukugqunywa kwe-WPC co-extrusion kufezekisa udidi lwe-Bfl-s1 ngokusebenzisa ukwakheka kwayo endaweni yokusetyenziswa kweekhemikhali zonyango, oko kuthetha ukuba ukusebenza komlilo kuyinto eqhelekileyo kwimveliso kwaye ayiwohloki kubomi benkonzo yesakhiwo. Kubaphuhlisi beehotele abafuna ukuthotyelwa kwemithetho kunye nokukhutshwa kwe-VOC okuphantsi, ukugqunywa kwe-WPC co-extrusion yinkcazo ehlangabezana neemfuno zombini ngaxeshanye ngaphandle komthwalo wokugcinwa kweeshedyuli zokubuyisela i-fire retardant.
Ukucacisa i-WPC Cladding yeeProjekthi zoHlaziyo lweeHotele: Izinto ekufuneka uziqwalasele
Iiprojekthi zokuhlaziya iihotele ezithatha indawo yezinto ezikhoyo zefaçade nge-WPC cladding zijongene nemingeni eyahlukeneyo yeenkcukacha kuneeprojekthi zokwakha ezintsha. Imeko ekhoyo ye-substrate, amandla okwakhiwa kodonga, kunye noyilo lwe-drainage plane zonke zichaphazela ukukhethwa kwenkqubo ye-cladding. Kwiihotele ezakhiwe ngaphambi kowama-2000, i-façade ekhoyo ingabandakanya ukwakhiwa kodonga olune-cavity enobunzulu obuncinci bee-subframes ze-cladding, nto leyo ethintela ukhetho lwenkqubo yokulungisa. Iiprofayili ze-WPC co-extrusion cladding ezivela kwi-Yida Wood ziyafumaneka kubunzulu nobubanzi obahlukeneyo ukuze zilungele ulungelelwaniso oluhlukeneyo lwe-subframe, kwaye uhlobo olukhaphukhaphu lwe-WPC (malunga ne-1.4 g/cm³ density, xa kuthelekiswa ne-2.7 g/cm³ ye-aluminium) kunciphisa umthwalo wesakhiwo eludongeni olukhoyo ngexesha lokuhlaziywa.
Kwiihotele ezisebenza ngexesha lokuhlaziya, ingxolo, uthuli, kunye nokuphazamiseka komsebenzi wefacade kuchaphazela ngokuthe ngqo amava eendwendwe kunye nengeniso. Ukufakelwa kwe-WPC cladding kuvelisa ingxolo nothuli oluncinci kakhulu kune-cladding yamatye okanye yethayile kuba izinto ziyasikwa kwaye zilungiswe ngezixhobo zokusebenza ngomthi eziqhelekileyo. Inkqubo yeprofayili yolwimi kunye ne-groove edibeneyo esetyenziswa kuluhlu lwe-co-extrusion cladding ye-Yida Wood ivumela ukufakwa ngokukhawuleza ngabasebenzi abancinci, kunciphisa ixesha lokwakha kwindawo nge-30 ukuya kwi-40 yepesenti xa kuthelekiswa nokuhlaziywa kwe-cladding yendabuko yokwakhiwa kwe-masonry. Kubaqhubi beehotele abangakwaziyo ukuvala ixesha elide lokuhlaziya, le nzuzo yesantya iguqulela ngokuthe ngqo ekulahlekelweni kwengeniso ngexesha lenkqubo yokuphucula i-facade. Uhlu lomlilo lwe-EN 13501 Bfl-s1 lusebenza kwinkqubo ye-cladding efakiweyo, ngoko ke indlela yokufaka kunye nezinto ze-subframe kufuneka zihambelane neemfuno zokusebenza komlilo - iinkcukacha ekufuneka amaqela okuthenga aziqinisekise nomthengisi we-cladding ngaphambi kokuba azibophelele kwinkcazo.
Imibuzo ebuzwa qho
Ithetha ukuthini i-Bfl-s1 ngamazwi alula?
I-Bfl-s1 yeyona rating iphezulu yokusabela kumlilo enokufikelelwa zizinto ezitshayo ezifana ne-WPC phantsi kwe-EN 13501-1. Igama elithi "Bfl" libonisa igalelo elincinci kakhulu emlilweni, kwaye elithi "s1" lithetha imveliso yomsi ephantsi kakhulu ngexesha lokuqala komlilo. Kwiifaçades zehotele, limele umgangatho wegolide wezinto ezitshayo.
Ngaba i-WPC cladding eqhelekileyo inokufikelela kwi-Bfl-s1 ngaphandle kokudibanisa kunye?
Enyanisweni, kunzima kakhulu. Iiprofayili ze-WPC eziqhelekileyo ezingenamaleko wesigqubuthelo sokukhusela esidityanisiweyo kunye nezizalisi zezimbiwa ezithintela umlilo embindini zihlala zifikelela kwi-Cfl-s1 okanye kwi-Cfl-s2. Inkqubo yokudibanisa kunye ivumela ukubekwa ngokuchanekileyo kwezongezo ezithintela umlilo kunye neqokobhe elikhuselayo elenza itshati elidibanisa ukusebenza kuluhlu lwe-Bfl.

Iimfuneko ziyahluka ngokwelizwe elilungu, ubude besakhiwo, kunye nohlobo lokuhlala. Nangona kunjalo, ngo-2026, uninzi lwamazwe e-EU aneekhowudi zokwakha ezihlaziyiweyo afuna ubuncinci i-Bfl-s1 yokugquma izakhiwo zikawonke-wonke ezingaphezulu kwemigangatho emibini, equka iihotele. Soloko ujonga iimfuno ezithile ze-national annex kunye ne-local building authority zendawo kwindawo yeprojekthi yakho.
Ingxelo yovavanyo lomlilo ye-EN 13501-1 isebenza ixesha elingakanani?
Akukho mhla wokuphelelwa omiselweyo kumgangatho we-EN ngokwawo, kodwa uninzi lwee-arhente zokwakha kunye nee-Notified Bodies zijonga iingxelo ezindala kuneminyaka emi-5 ukuba zifuna ukuhlaziywa okanye ukuqinisekiswa kwakhona, ingakumbi ukuba inkqubo yokwenziwa kwemveliso okanye yokwenziwa kwayo itshintshile. Amaqela okuthenga kufuneka acele iingxelo ezibhalwe kwisithuba esingaphantsi kweminyaka emi-3 ukuze zamkelwe ngokupheleleyo.
Ngaba izinga lomlilo le-WPC cladding liyancipha ngokuhamba kwexesha xa lifakwe kwi-façade?
I-WPC cladding esemgangathweni kunye ne-co-extrusion yenzelwe ukugcina ukusebenza kwayo komlilo emva kokutshintsha kwemozulu ngokukhawuleza. I-EN 15534-1 kunye namaxwebhu ovavanyo ahambelanayo afuna ukuba ukusebenza komlilo okubhengeziweyo kuhlale kusebenza emva kwemigaqo yokuguga echaziweyo. Abathengi kufuneka bacele ubungqina bokusebenza komlilo emva kokutshintsha kwemozulu kumthengisi wabo.
Ngawaphi amaxwebhu endifanele ndiwacele kumthengisi we-WPC cladding kwiprojekthi yehotele?
Cela amaxwebhu amane: (1) iSibhengezo sokuSebenza (iDoP) esibhekisa kwi-EN 13501-1 kunye ne-Euroclass ebhengeziweyo, (2) ingxelo epheleleyo yovavanyo evela kwiBhunga eliNotisiweyo elivunyiweyo, (3) isiqinisekiso sokumakishwa kwe-CE, kunye (4) ubungqina bokuba ingxelo iyasebenza kulwakhiwo lwemveliso oluchanekileyo olu-odolayo. Ukuba umthengisi akanakukwazi ukubonelela ngazo zone, cinga ngababoneleli abahlukileyo.
