Kuze kube manje bekungekho umbhalo onje ochaza ngendlela elula nefushane ukuthi iziphi izibuko okufanele zikhethwe ezinsimbini zefenisha. Uzothola impendulo ecacile nencazelo, ebhalwe ngendlela yokuthi ibe lula ukuyiqonda kuwo wonke umuntu. Umbhalo ungakongela imali eningi, kodwa futhi ungaphula izinkolelo ezikhona kubantu abangu-95%.
Glass ithatha indawo enkulu yewindi (evulayo). Njengoba kubalulekile ukuthi amaphrofayili enziwe ngokhuni ahlanganiswe ndawonye, kubaluleke kakhulu ukuthi ingilazi ingakukhiphi ukushisa egumbini ebusika, nokubanda ehlobo.
Isithombe 1 – izici ze-Ug kanye ne-g
Ngakho-ke kunezici ezimbili ezichaza lawa manani:
I-Ug factor ibonisa ukulahlekelwa ukushisa (amandla) egumbini. Uma kunegumbi elishiswa ebusika, leli nani lizokhombisa ukuthi kushisa okungakanani okudlula engilazini bese kuphumela ngaphandle.
Ngobuchwepheshe: Ug - i-coefficient yokudlulisa ukushisa , ekhishwe ngokuvumelana ne-standard EN-673 , iyunithi yayo engu W/m2K . Uma inani le-U liphansi, kuba ngcono ikhono lokuvikela ukushisa .
Isici G singukudlula kokushisa kungene ekamelweni. Ngokuphambene nesimo sokuqala, lapho ehlobo sinendawo egqunywe umoya opholile, lesi sici sikhombisa ukuthi kushisa okungakanani okudlula ngengilazi.
Ngobuchwepheshe: g - ukudluliswa okuphelele kwamandla elanga ngengilazi. Kuchazwa ngokwejwayelekile EN-410. Uma kuyincane, kushisa kancane isikhala sangaphakathi.
Asihambe ngohlelo.
Ingilazi yongqimba olulodwa.
Isb. ehlobo, lapho amazinga okushisa asuka ku 35o kuya ku 40o, ingilazi eshiselwa yilokho kushisa idlulisela lokho kushisa kwayo egumbini. Uma le ngilazi iyeyodwa (ngokwesibonelo engu 3mm ubukhulu), izodlulisa 100% kokufudumala kwayo. Lapha kufanele kugcizelelwe khona manjalo lokhu “kokufudumala kwayo” bese kuthiwe uma ngaphandle kunjengoba isibonelo 40 amadigri, ngaphakathi ngeke kube yikho nakanjani 40 amadigri, kodwa kuzoba yilokho ingilazi uqobo ekwazi ukufudumala kube yikho (slika 2), ngoba empeleni ikhipha lokho kushisa (okuzoba esimweni sengilazi eyodwa 100% wokufudumala). Lokho kufana nokuthi egumbini sinento yokushisisa enobuso obulingana nengilazi. Lesi yisimo sokudlula kokushisa kusuka ngaphandle kuye ngaphakathi (i-G factor).
Isithombe 2 - Izinga lokushisa lengilazi ekushiseni kwangaphandle kwe-0 naselangaphakathi le-20
Uma kukhulunywa ngokudlula kwamandla ukusuka ngaphakathi ukuya ngaphandle (I-Ug factor), endabeni yengilazi eyodwa cishe kucishe kube 83% wamandla. Okusho ukuthi, 83% emakhazeni (ehlobo) ilahleka ngaphandle.
Manje sesiza ekutheni i-coefficient ye-Ug iyini ngempela. Ngalolu hlobo lwengilazi, abantu babe sebethi i-Ug yayo ithi 5,3 kuya kokuthi 5,8. Lawa ama-coefficients aboniswa njengama-coefficients conductivity engilazi.
Sinalolu hlobo lwengilazi ezindlini ezindala. Njengoba lokhu kulahlekelwa kwamandla kuphezulu kakhulu, amawindi acwebezeliswe kabili enziwe (amaphiko amabili ahlukene, elinye ngemuva kwelinye) futhi sisenamafasitela anjalo namuhla kwezinye izindlu nezakhiwo (isithombe 3). Kwabe sekwenziwa isinyathelo esilandelayo sokuthuthukisa, okuyi…
Umfanekiso 3 – izinhlobo zakudala zamafasitela anezicabha ezimbili
Ingilazi ekabili (kabili)
Ingilazi eyenziwe ngezingilazi ezimbili, futhi phakathi kwazo kukhona ukubumba isb.16mm (4+16+4).
Isithombe 4 - Izingqimba ezimbili zengilazi ezinobukhulu 4mm, ezihlukaniswa yisikhala se-16mm
Amanani okuqala nawokugcina “4” abonisa ukujiya kwengilazi okungu-4mm, futhi inani eliphakathi “16” libonisa ukujiya kokubumba okuphakathi kwawo. Ubukhulu bokubumba bungahluka ukusuka kokuthi 6mm kuye ku-24mm, kodwa ibanga elinikeza imiphumela ehamba phambili nalapho imiphumela iyinhle kakhulu yibanga (lokubumba) ukusuka kokuthi 12-16mm. Njengoba nje ukubumba okuvela kokuthi 6,8,9, mm akukuhle, ngakho-ke lezi ezisuka kokuthi 22, 24mm azilungile nazo (thina enkampanini singathi “ziphuka ngokufana”).
Manje njengoba sesazi ukuthi ilebula ngayinye isho ukuthini, yisikhathi esifanele sokunikeza ithebula esingalilandela.

Ithebula 1 - Amanani ezinto ezingu Ug ne g, ngokuvumela kokukhanya
Siyabona ukuthi ngemva kokwengeza ungqimba olulodwa lwengilazi esikhundleni senani le-Ug elithi 5.3, sithole ukuthuthukela kokuthi 2.8. Okungukuthi, esikhundleni sokuthi ukushisa okungu-100% kuphume ebusika, uthola ukuthuthukiswa kokuthi 56%, kanye nokushisa okungu-77% kungena ehlobo. Ngakho-ke sithole ukuthuthuka okukhulu ngokwengeza ingilazi eyodwa.
Isiphetho esinengqondo siyavela ngokushesha, “Bese wengeza olunye ungqimba lwengilazi (ingilazi enezendlalelo ezintathu) futhi sizothola imiphumela engcono kakhulu!”, kodwa akunjalo.
Kunamanani athile alungile afaka izici zokushisa/ezibandayo, ukukhanya kwelanga, njll. futhi sizobona ukuthi kusukela kuleli phuzu, ukwengeza esinye isendlalelo sengilazi esendlaleloni esivele sikhona kakade kungaba umnyakazo wokumaketha, umthengi okumele awukhokhe kahle.
Ngaphezu kwesinye isendlalelo engilazini enezingqimba ezimbili, kulo mzuzu, i-argon iphinde ifakwe endabeni, ekhuthazwa kakhulu ngabantu ababhekene nokumaketha ezinkampanini. Sisho okuningi, yiqiniso kunezizathu zokudumisa, kodwa ngokuqinisekile hhayi njengoba kushiwo futhi izizathu ezishiwo azilona iqiniso ngokuphelele. Kuthebula singabona ukuthi uma i-argon ifakwa engilazini evamile enezendlalelo ezimbili enenani le-Ug elingu-2.8, kutholwa inani le-Ug elithi 2.6. Lokho kuthuthukiswa okuncane okungu-0.2 kuphela kukhokhelwa kakhulu kunokuthuthukiswa kwangempela okuzuziwe. Lokhu kuthuthukiswa kuhle kuphela kwezinye izimo, futhi sizochaza ukuthi yikuphi kamuva.
Impela, sibhala konke lokhu futhi sikuhlobanise nengilazi enezingqimba ezimbili, ngoba “kunokuhlukahluka okuningi kwetimu”. Ake sithathe isibonelo sokuza kwakho esitolo sengilazi:
Wena: Sawubona
_Ummashi wengilazi: Sawubona
Wena: Ngifuna ingilazi ye-izo eyodwa, ephansi-emission futhi egcwaliswe nge-argon
Umlungisi wezingilazi: Yebo
Umsiki weglasi akakukhohlisanga. Uthole ingilazi ye-insulation enokukhipha okuphansi (LOW-E), egcwaliswe nge-argon, kodwa akakutshelanga ukuthi lena ifilimu eqinile. Kuleyo ngilazi sithola Ug-1.8 futhi uma igcwaliswe nge-argon 1.6. Futhi ingabe uyabona ethebuleni ukuthi ayini amanani engilazi enokukhipha okuphansi enefilimu ethambile (4+16+4 LOW-E MEKI FILIMI). Lelo nani, ngisho nangaphandle kwe-argon, lingu-Ug-1.3, okungcono kakhulu kunefilimu eqinile ene-argon, futhi intengo iphansi. Uma le ngilazi nayo igcwaliswa nge-argon, Sithola Ug-1.1. Lapha-ke sifika kuleso simo lapho i-argon ibaluleke kakhulu. Leli nani elithi Ug-1.1 liyinani elidingekayo emthethweni eminingi yaseNtshonalanga Yurophu ebhekene nokulawulwa kwale ndawo, lapho ingilazi ilethwa ngaphakathi kwemikhawulo yamanani avunyelwe futhi njengaleyo ingasetshenziswa embonini yezokwakha. Ngakho-ke, i-argon ayigcwaliswa kakhulu ngenxa yokufakwa kwe-insulation, njengoba iningi licabanga, kodwa ngenxa yokuthi i-argon empeleni iyigesi engathathi hlangothi - ayinobudlova njengomoya. Ifilimu efakwa ngaphakathi kweglasi (phakathi kwezendlalelo ezimbili) isekelwe ku-aluminium oxide, futhi uma lowo mgudu ongaphakathi ungagcwaliswa nge-argon, ngokuhamba kwesikhathi uyalinyazwa umoya ovamile bese uyanyamalala, ngalokho kulahleke ukufakwa kwe-insulation kanye namanani aso esasinawo ekuqaleni.
Futhi, kukhona abameli abathi, njengengxabano yokungangezi i-argon, bacaphuna iqiniso lokuthi i-argon “ivuza” engilazini ngokuhamba kwesikhathi, okungukuthi iyanyamalala futhi sikhokhela ukugcwalisa i-argon mahhala. Lokhu kuyiqiniso, kodwa kancane. Inani lokulahlekelwa kwe-argon lincike kumkhiqizi wengilazi, ngakho-ke ngokubambisana kufanele ukhethe izinkampani ezinesitifiketi sokuthi ukulahlekelwa kwe-argon akukhulu kuno-3% iminyaka engu-10. Lokhu kusho ukuthi eminyakeni engu-10 ngeke silahlekelwe ngaphezu kuka-3% kwe-argon, futhi lokhu kulahlekelwa kuyinto engathi sína futhi ezimeni zangempela, i-argon idlula ingilazi.
Futhi kukhona okuhlukile lapho izibuko zigcwaliswa khona nge-krypton, kodwa lokhu kwenziwa uma kudingekile ukuze kutholwe ukwahlukanisa okungcono ngezingilazi ezizacile, kodwa lokho ngeke kube isihloko sethu manje.
Sizobheka le nhlanganisela yengilazi. Ngakho 4+16+4 LOW-E IFILIMU ELIthambile. Inani layo lingu Ug-1.1. Lokho kusho ukuthi ebusika kuphuma 22% sokushisa ngaphandle, esikhundleni salokho 56%, kodwa ehlobo kungena 63% sokushisa ngaphakathi. Lokhu kuyintuthuko enkulu uma kuqhathaniswa nengilazi evamile ehlanganisiwe, kodwa kuyisinyathelo esincane uma kuqhathaniswa ne-g factor.
Imithetho lapha kakhulukazi isekelwe kunani lika-Ug, elisho ukulahlekelwa ukushisa ebusika, kodwa abantu ngokuqinisekile bafuna ukunethezeka kokusetshenziswa ehlobo, lapho bengafuni khona ukushisa kungene egumbini. Ngakho-ke, i-SOLAR 4+16+4 FLOT yenziwe, lapho izici zahlala zifana nokuthi 4+16+4 LOW-E SOFT FILM yehliselwa ekamelweni lokushisa ehlobo, kodwa i-LOW-E SOFT FILM ibe yindawo yokushisa yasehlobo. 42%. Lona umkhawulo ophansi esizindeni sezingilazi ezibonisa ngale. Konke okunye ukuncishiswa nokuthuthukiswa kwezici ze-Ug no-g kuqala ukuvela ekukhanyeni kwengilazi (eyaziwa nangokuthi ingilazi engafakwanga). Le nhlanganisela iyinhlanganisela yekhwalithi ephezulu kakhulu yezingilazi ezibonisa ngale, neqiniso lokuthi sisenezendlalelo ezimbili zengilazi.
Ingilazi enezingqimba ezintathu
Kancane kancane sifinyelela esiphethweni, futhi ngeke asekele umakhelwane ocebile othi, “Ngibeka amafasitela acwebezelwe kathathu abiza kakhulu endlini yami. Akutholi lutho olungcono kunalokho.”
Isithombe 5 - Isampula yewindi elinengilazi enezingqimba ezintathu
Masibuyele kuthebula 1 futhi sibheke amanani anayo ingilazi enezingqimba ezintathu. Lokho ngu-Ug-1.8 no g-1.7, kanti kwengilazi enezingqimba ezimbili sithole 1.3 no 1.1 futhi lokho ngemali encane kakhulu, ngoba leyo ngilazi ishibhe kakhulu kuneyenqimba ezintathu.
Senzeni ngokucwebezela kathathu? Senze iwindi/umnyango waba nzima kakhulu, sakhuphula intengo…..futhi senza umkhiqizo waba mubi kakhulu.
Linda. Ingabe ifilimu ethambile, i-argon, njll. ingangezwa lapha futhi?
Kungaba. Uma sithatha 4+16Argon+4+16+4LOW-E. Kulesi simo sizothola Ug-0,8 futhi i-g factor nayo icishe ibe ngu 60% (akukho okukhethekile).
Ukuthuthukiswa okuphezulu ngezingilazi ezinezendlalelo ezintathu, esingazithola, kuyinhlanganisela yalokhu:
Solar4+16Argon+4+16+4LOW-E. Khona-ke kutholakala i-Ug-0.6, kanti iphesenti lokungena kokushisa lingaphansi kuka-40%.
Asiqhubekele ku…
Isiphetho:
Uma ufunde ngokucophelela umbhalo odlule futhi walandela ithebula lamanani ezinto ngokuhambisana, isiphetho sizobe sesicwebezela kwenye indawo, mayelana nayo yonke indaba emayelana nezibuko.
Ingilazi enezingqimba ezimbili enokukhishwa okuphansi, enefilimu ethambile, egcwaliswe nge-argon iyinhlanganisela engcono, futhi eshibhe kakhulu, kunengilazi ejwayelekile enezingqimba ezintathu. Inzuzo eyengeziwe yi-iqabunga elikhanyisiwe, lapho impilo yewindi yandisa.
Leli qiniso lidala ukungabaza phakathi kwabantu ekuqaleni, nalabo abangabuqondi ubuchwepheshe bokukhiqiza ingilazi (futhi abasaqonda yonke into), bawela kalula engxoxweni emnandi yabantu umsebenzi wabo owukunciphisa uhlu lwamasheya.
Yebo, kodwa kukhona nezingilazi zezendlalelo ezintathu ezinenhlanganisela ethile zinikeza izici ezingcono kune-4+16+4LOW-E SOFT FILM!?
Yebo, zikhona. Zikhona, kodwa intengo yazo iphakeme ngokungenakuqhathaniswa kunalokho izibuko ezinjalo ezikwazi ukukunikeza, futhi lelo phuzu. Singasho ukuthi ezimweni ezinjalo intengo yengilazi (m2) ikhuphuka kakhulu ngokuhlobene nekhwalithi etholiwe.
Thola 4+16+4LOW-E SOFT FILM!
P.S.
Ungamangala ngeqiniso:
Ngeke ukwazi ukuzihlolela ukuthi iyiphi ingilazi oyitholile! Kukhona umtshina wengilazi okwazi ukubona uma unengilazi ecwebezelisiwe kabili noma ingilazi yeprimiyamu enefilimu, kodwa kubiza ama-euro angamakhulu ambalwa/izinkulungwane. Kukhona indlela engenziwa elabhorethri, kodwa ubani omunye oqale athathe iwindi aliyise elabhorethri, akhokhe inani lokuhlolwa, bese elifaka endlini noma efulethini.
Sizozivikela ngokukhetha inkampani efakazelwe futhi eyaziwayo esisebenzisana nayo, ngoba ayikhokhi ukudlala ngokuzethemba. Akufanelekile ukuthi amaphoyisa okwakha e-Austria ayale ukuthi asuse amafasitela ezakhiweni noma aguqule uhlelo oluvele lusungulwe lokukhiqiza nokufakwa.
Uma ukhetha ubuciko obusha bokhuni futhi ufuna isilinganiso esihle phakathi kokufakwa kwe-insulation, ukuqina kanye nentengo, bheka amafasitela ethu okhuni, amafasitela okhuni-aluminium noma usithumele ubukhulu ukuze uthole ikhotheshini.
