I-S3, E22: I-Cavity Wall Insulation: Inkinga Efihliwe No-Damian Mercer We-Cavity Extraction

Okulotshiweyo okukhiqizwe ngedijithali (kungase kuhlanganise amaphutha athile)

[00:00:03] USteve Randall: Sawubona futhi wamukelekile ku-Constructive Voices. NginguSteve Randall. Kulesi siqephu, sikhuluma nge-cavity wall insulation. Manje, kungase kungabi into e-sexy, kungase kungabi into oye wacabanga ngayo muva nje, kodwa kunenkinga ezindaweni eziningi nasezindaweni eziningi, futhi empeleni kungase kube ihlazo likazwelonke. Ake sithole okwengeziwe kusivakashi sethu.

[00:00:32] UDamian Mercer: Sawubona, igama lami nginguDamian Mercer. Ngingumnikazi nomqondisi weCavity Extraction Ltd.

[00:00:39] USteve Randall: Brilliant. Siyakwamukela ku-Constructive Voices, Damien. Nginesiqiniseko sokuthi iningi lezethameli zethu likwazi kahle ukuvaleka kodonga lwezimbotshana, kodwa ukuze nje usinikeze umbono omfishane, kuyini?

[00:00:48] Damian Mercer: Cavity wall insulation is the insulating off a property to reduce your carbon footprint. The retrofit side of cavity wall insulation is where it’s pumped in after the building has been built. When you’re getting a new build and they’re insulated, they are built in situ so that there’s usually a gap between the insulation and with a retrofit, it is a full fill cavity system.

[00:01:19] USteve Randall: Futhi sikhuluma ikakhulukazi namuhla mayelana nemiphumela yokuhluleka kokufakwa kodonga lwe-cavity.

Kuvame kangakanani lokhu futhi hlobo luni lwezinto ezenzekayo uma lokhu kwehluleka ukubuyisela?

[00:01:31] Damian Mercer: Cavity wall insulation is failing at an alarming rate to me. You know, my business has been going 10 years and we’ve seen it grow year on year since it started. We extract from private and commercial situations like housing associations and people like that. And we’re at first, 10 years ago, we were doing a couple of extractions a week. We are rattling through between 10 and 15 extractions a week now. Cavity insulation and the numbers obviously have increased because there was a government incentive of making sure that the properties in the UK met a minimum standard with their EPCs. So there was a big drive on retrofitting insulation.

Futhi, uyazi, ngicabanga ukuthi isibalo sokugcina bekuyindawo ephakathi kwezigidi eziyi-14 nengxenye ezweni lase-UK esifakwe nokufakwa kodonga lwezinsimbi.

[00:02:34] USteve Randall: Ngakho-ke sikhuluma izinombolo ezinkulu. Uma izinto zingahambi kahle, kuba nemithelela kwezezimali, kwezemvelo, kwezempilo. Ngisho ukuthi zonke lezi zinto ziyathinteka. Pho kwenzekani?

[00:02:44] UDamian Mercer: Into evamile ukuthi uzoqaphela ukuthi kukhona isikhunta noma umswakama ovela kwezinye zezindonga, ikakhulukazi ezinyangeni zasebusika lapho uzama ukugcina ingaphakathi lakho endaweni yakho liku-19 degrees futhi kuphume amabili ngaphandle. Endaweni ethile phakathi kokususa okubili nokungu-19 degrees nguziro. Nansi indawo yamazolo. Futhi uma wehlulekile ukufakwa odongeni lwe-cavity, izohluleka kokusebenza emgodini noma indawo ebandayo ngaphakathi kwendawo efakwe kabusha efakiwe ngokwayo. Bese kuthi lapho ukwakheka kwephuzu lamazolo, kumanzise i-insulation. I-insulation iba manzi ngokulandelayo, imanzise ingaphakathi noma ikhuphule inani lomswakamo lemvilophu yangaphakathi yendawo futhi lokho kubangela indawo yokuzalela ibe manzi bese isikhunta bese kuba nemithelela yezempilo engalandela lolo hlobo lwenqubo, kusukela. noma yini kusukela ku-asthma, izimo zesikhumba kuya ekwandeni kwe-COPD nezinto ezinjalo.

[00:03:51] USteve Randall: Futhi ingabe ucabanga ukuthi le nkinga yokufaka udonga lwe-cavity ehlulekile ivamise ukubonwa ngokungeyikho, ikakhulukazi ngabanikazi bezindlu? Uma bengalethi muntu, bangase bacabange ukuthi mhlawumbe isiphephetha-moya lapha nalaphaya sizokulungisa, noma mhlawumbe ama-seal adlulele, ukucwebezela okuphindwe kabili futhi uma nje bekulungisa lokho, kungaba balungise futhi empeleni kuyinto engathi sína kakhulu okufanele bayibheke.

[00:04:11] UDamian Mercer: Yebo, izakhiwo eziningi esiya kuzo, uyazi, othile ushilo, oh, lokhu kuzoba fan yakho ye-extractor noma awunayo fan ye-extractor noma awukayitholi. uvule iwindi lakho noma awunawo umoya owanele. Impela njengohulumeni bekufanele ngabe siphenye izinqubo zokufakwa kabusha kwe-retrofit insulation, ikakhulukazi ukugqunywa kwemigodi, futhi ungaba yini umthelela walowo mkhiqizo esitokisini sezindlu sase-UK? Manje, esivame ukukuthola kulapho abantu bengahlonzanga kahle, futhi benza ngaso sonke isikhathi, abahloli abamanzi bazothi, oh, unomswakama okhuphukayo futhi sizongena futhi sizogebenga i-900 phezulu yonke indlela. phansi kwendlu yakho futhi sizokunikeza umjovo wekhemikhali bese siwuplameka kabusha. Lokho kufana nje ne-plaster enamathela phezu kwenkinga. Isizathu sangempela ukuthi kufanele ubheke leyo mbangela futhi kungaba noma yini kusukela emigqonyeni yamasondo esendaweni engafanele ukuze ufake ngokungafanele udonga lokuvala umgodi ezindabeni zokulungisa ngaphandle kwendawo uma usezindaweni zokuchayeka kakhulu. Kodwa izinkinga zangempela esinazo ngokufakwa kodonga lwezinsimbi ukuthi kufakwe endaweni engafanele ohlotsheni olungalungile lwezindlu. Futhi esikutholayo ukuthi sibizwa ngaso sonke isikhathi ukuthi siphume siyokwenza imisebenzi yokulungisa leyo ndawo. Manje, ngokwezindleko eziphansi, uyazi, uma ukhipha indawo, kungaba ndawana thize, uyazi, indlu evalekile yama-1940s, isibonelo, cishe cishe ama-square metres ayi-105, 110 square metres, ungaba noma kuphi phakathi kuka-2,500. kuya ku-£3,500 kuleyo ndawo. Kuye ngohlobo lwe-insulation. Ngakho kungaba i-fiber noma i-glass fibre noma ubuhlalu be-polystyrene. Kunezinhlobo ezahlukene zamagwebu. Kunenye esabalele kakhulu emaphephandabeni muva nje ngezimangalo zomthetho we-SSB lapho besebenzise igwebu le-urethane, okuyigwebu eliqinile elingena ngaphakathi kwemigodi. Futhi okuwukuphela kwendlela yokuyisusa ngempela ukuwisa ukuphakama okungaphambili. Bese kuthi amakhehla angempela asukela eminyakeni engu-25 plus, uzohlangana nento ebizwa nge-urea formaldehyde, okuyigwebu elimhlophe okulula ukulikhipha ngoba liyaphuka ngempela uma ufaka izinkampani zezindiza neziswebhu lapho. Uma nje unendawo yokufinyelela enhle yokuyisusa nge-vacuum futhi, iqonde ngempela. Kodwa-ke, uyazi, kunenkinga nge-cavity wall insulation. Futhi ngicabanga ukuthi yehlela esitokisini sezindlu, kodwa futhi yehlela kuzinqubomgomo zikahulumeni ngokunciphisa i-carbon footprint. Futhi ezinye izinkampani zinesithakazelo esikhulu ekutheni ingakanani ikhabhoni ezingayivuna endlini yakho kunokunciphisa isikweletu sakho sokushisisa. Bese kuthi-ke, uma kungumkhiqizo ongalungile, kuzokubiza kakhulu ngoba uthola imvilophu emanzi ngaphandle kwendawo yakho. Futhi uma unemvilophu emanzi, kuba nzima ukuyishisa. Kuyafana nokuthi siye kobhukuda olwandle. Uma usungene olwandle, uzobuya uphume. Asikho isidingo sokukumboza ngengubo emanzi ngoba awusoze wafudumala. Wena, uyafudumala lapho ubeka ingubo eyomile noma ithawula elomile, elomile eduze kwakho. Futhi kuyafana, kuyinqubo efanayo ncamashi. Uma une-insulation emanzi endlini yakho, into yokuqala okufanele uyenze ukufudumala lezo zindonga ezimanzi noma ezinombobo omanzi kuqala, bese uzwa inzuzo yokuzama ukuwufudumeza. Kodwa ngokushesha nje lapho lokho kushisa kucisha kusihlwa futhi ukushisa kuqala ukuphuma endlini yakho ngenani elisheshayo, uzobona ngokushesha ukuthi unenkinga. Uyazi, imvilophu eyomile engenakho okokufaka empeleni isebenza kangcono kunesakhiwo esihlulekile ukufihlwa odongeni.

[00:08:28] Steve Randall: Now, we’ve seen situations change with materials that are used. So the one that always comes up is asbestos. You know, we wouldn’t use that these days. I know some countries still do. And then there are situations like the rack scandal, which of course affected many, many buildings, schools, hospitals, and that became a big national scandal. Are we talking about this in terms of just the wrong materials used at the time or with hindsight there were the wrong materials or are we in scandal territory with this, do you think?

[00:08:59] UDamian Mercer: Umuzwa wami siqu ukuthi kancane kwakho kokubili. Ngicabanga ukuthi ngenkathi ohulumeni ngo-1992, lapho besayina isivumelwano sokuqala sase-Kyoto, okuyizivumelwano ezibheke ukunciphisa i-carbon footprint, ngicabanga ukuthi lowo mbono wawuthi sizokwenza kanjani lokho. Futhi ngenxa yokuthi sisayine kukho, mhlawumbe kube nokwethuka okuncane ngoba lokho kwafakwa ku-, ukunciphisa i-carbon footprint yafakwa ezinkampanini zamandla. Futhi kanjani, bazokwenza kanjani? Hhayi-ke, masisebenzise i-cavity wall insulation. Asifake ngaphakathi kuleso sikhala. Ingabe yinto elungile noma engalungile? Ngicabanga ukuthi kwezinye izimo ukwahlukanisa imbobo yodonga kungaba yimpahla ephelele endaweni yakho. Kodwa uma usendaweni ye-exposure 4, ngakho-ke iCumbria, iningi logu lwaseLancashire, ugu lwase-Welsh lwehla noma yini esentshonalanga isondela ohlangothini lwezwe, usendaweni engcupheni yemvula eqhutshwa umoya. Imvula eqhutshwa umoya kanye nokubuyisela. I-Cavity wall insulation ayihambisani ngempela futhi ngicabanga ukuthi lokho bekunganakwa yiningi lalezi zinkampani. Babenesithakazelo esikhulu ekuvuneni ikhabhoni esikhundleni sokuvala izakhiwo. Ngakho-ke uyazi, kungaba yini ikhambi? Isixazululo wukukhipha bese ucabanga kabusha bese ubheka i-retrofit.

Umhlaba udinga ukubheka izindlu hhayi esikalini sekhodi yeposi kodwa ngomuntu ngamunye. Futhi eminyakeni yamuva nje siqale ukwehla ngaleyo ndlela. Basebenzise izindlela ezintsha zokufaka imikhiqizo engcono futhi manje sekungcono kakhulu. Kodwa phambilini izinkampani eziqinisekisa ukuthi azizange zikuqinisekise lokhu kufakwa. Lezi zinkampani ezasungula ama-installer esezinyamalele, uyazi zivele zanyamalala ngoba zehlisa isikweletu sazo. Ingabe ihlazo? Ngicabanga ukuthi manje kungenxa yokuthi eminyakeni eyi-10 edlule sitshele abantu mayelana nokufakwa kwe-cavity okuhlulekile kanye nezinkinga enazo futhi uyazi, ekuqaleni bekuyi-poo pooed. Uyazi, abantu abazange ngempela. Hhayi-ke asikholwa ukuthi manje sebengabona okwangempela, izinkinga ezidalwa yikho. Uyazi, izinhlangano zezindlu zisusa lo mkhiqizo futhi zifuna imikhiqizo engcono manje ukuze kuncishiswe i-carbon footprint yazo. Ikhumbula izakhiwo zenhlangano yezindlu zibheke ukuthola isilinganiso se-EPC esingu-C noma esingcono. Futhi ukuthi bakwenza kanjani lokho, banjalo, babheke enye yokuthuthukisa ukunethezeka kwezindlu zamakhasimende abo kodwa futhi bathuthukise isitokwe sezindlu futhi bangase babheke ukufakwa odongeni kwangaphandle.

All these type of retrofits can be Good in certain situations. But when they were not policed like they were previously, there’s problems. I was down in Westminster just Recently speaking to MPs about fail cavity wall insulation and we sort of, when they were asking me sort of the scales of this, if we’re looking at 14 and a half million, which I think it’s actually more, I think it’s probably close to 15 and a half million now, if that is that figure. And then there was a independent study carried out by the BBA CIT over in Northern Ireland where they investigated the housing stock of Northern Ireland. And that report was an independent body that looked at it and they came up with a figure of 75% of the housing stock in Northern Ireland was either failing, failed or incorrectly installed. Wow. So those three bodies, if you transferred that over to the uk, which there is a correlation between the type of housing stock in Northern Ireland and what we have over here, 75% of 14 and a half million quid is an awful lot of homes. The scandal part of it is when they go to the guarantee company to say we have fail cavity wall insulation, they are left really high and dry because, you know, a company might come out and say, have you had your windows changed? Yes, I’ve had my windows changed because they were looking a bit dilapidated and you know, we’ve done some maintenance. Well, you’ve disturbed the insulation so your guarantees null and void. But then in the same terms and conditions further down the page, it says if you do not maintain your property, you will also void your.

[00:14:04] USteve Randall: Yebo, uyazi, bakuthole noma ngayiphi indlela.

[00:14:06] UDamian Mercer: Yebo, banawe noma ngayiphi indlela. Ngakho-ke iphepha, alifanele iphepha elibhalwe kulo futhi lezi zinkampani kufanele ngabe zithathwe ngamaphoyisa, kodwa empeleni zazisebenza ngamaphoyisa.

[00:14:18] USteve Randall: Futhi ngicabanga ukuthi into lapha, Damian, ukuthi, uyazi, sikhuluma ngale ndaba eyodwa, kodwa siyazi ukuthi kuzoba nazo zonke izinhlobo zezinqubomgomo mayelana nokunciphisa. i-carbon footprint nezinye izindaba zemvelo. Futhi indlela ohulumeni nabenzi bezinqubomgomo abavame ukusebenza ngayo ukuthi, badinga ukukwazi ukuyithengisa emphakathini nakulabo okufanele benze umsebenzi. Ngakho babheka izixazululo ezingenziwa ngezinga. Ukuthi zifanelekile noma cha, zingenziwa ngesilinganiso ukuze kugcinwe izindleko ziphansi. Ngakho-ke lena indawo eyodwa futhi cishe kuzoba nezinye izinto ezizofana nalezi ezilethwa yinqubomgomo. Zibekwe ngoba kuyisixazululo esinoshukela, noma kungesona esilungile. Ngakho-ke ngicabanga ukuthi kubaluleke kakhulu ukuthi nenze umsebenzi wokunxenxa owenzayo nohulumeni. Niyazi, yini, bathini? Ingabe, ingabe bakunikeze umqondo wokuthi, yebo, kulungile, siyakwamukela ukuthi lesi isimo, sizokwenza lokhu, lokhuya nokunye, noma abazange basho lutho ngempela?

[00:15:21] UDamian Mercer: Abasho lutho ngempela. Akusizi ngaso sonke isikhathi lapho sithola ukufakwa kwe-cavity kulethwe phambili. Uyazi kuke kwaba nama-MPs abake baba nezinkulumo mpikiswano e-House of Commons, uyazi, lapho sibanikeze khona ulwazi futhi sifika kude nabo, kungazelelwe kube nokhetho lukazwelonke noma. , niyazi, uRishi Sunak, wabiza ukhetho lukazwelonke emasontweni amabili ngemva kwesethulo sami sokugcina, ekhuluma ngokuhluleka kwe-cavity insulation nabantu abaningi abahileleke kulo mthetho we-SSB. Lawo malungu ePhalamende abekhona, ukuthi izingxenye ezimbili kwezintathu zawo azisekho. Ngakho-ke sibuyela kwesikwele sokuqala futhi. Bonke babhalisele ukunciphisa i-carbon footprint. Bonke bahlezi lapho beyiphusha, kodwa empeleni ababheki imiphumela engemihle ezinkingeni okungenzeka ukuthi unazo ngokufakwa kodonga lwe-cavity. Uyazi, ngangisembukisweni we-Jeremy vine eminyakeni eyisithupha, eyisikhombisa edlule, wathi kimi, damian, ibhizinisi lakho akufanele libe khona. Impela.

Uma yenziwe ngendlela efanele, ifakwe ngendlela efanele, igcinwe ngendlela efanele futhi inamaphoyisa ngendlela efanele, ibhizinisi lami belingeke libe khona.

[00:16:38] USteve Randall: Yebo, ngokuphelele. Futhi uke wagqamisa isikali sodaba. Futhi futhi, ngohlobo lohulumeni nabakhi bezinqubomgomo, bayathanda ukukhuluma ngezinto ezihehayo. Ngakho kwabanye abantu, ukukhuluma ngakho ukunciphisa i-carbon footprint is sexy. People who care about the environment, care about the planet. That’s the sort of language they want to hear. What they don’t want to hear about is cavity wall insulation, because that’s less sexy. So that is part of the problem as well, that politics, particularly these days, is all about talking about those things that you think the electorate want to hear about and not talking about maybe some uncomfortable truths.

[00:17:14] Damian Mercer: And I totally agree with you about, you know, when they talk about the sexy stuff, you know, they like to be seen, we are reducing your fuel costs by insulating your properties. What they seem to forget is the people that they are insulating housing to, like people are in fuel poverty, they can’t afford to maintain those properties. So, you know, if they get a little bit extra money in their pocket because their bills at the beginning have been reduced, they’re going to spend that on things that they need that they’ve been missing out on. Previously that money will be re spent. They’re not going to put that money into a bank account and go oh and five years time we’ll have to repoint that wall. That money doesn’t go, it doesn’t work like that in the real world. And when the maintenance of the property then starts to fail, you then have the problems of the ingress failing the insulation. And we start, we enter this a never ending circle of chasing your tail again. Cavity insulation, when it goes wrong, it goes wrong and there is a cost implication, a cost implication that actually outweighs the saving situation. So when we are looking at fuel poverty or let’s go and insulate everybody’s house, it’s not really the right way forward. I think, you know, there are, it needs to be looked at differently. And I’m all in favor of insulating houses and ventilating houses because insulation and ventilation should go hand in hand. But it needs to be looked at on its individual basis and postcodes or streets. One street end of the street can be higher than another end of the street might be in a valley. So you’ve got high exposure at the top at one end and sheltered at the other. You know when they say oh we’ll go and insulate that street there. It’s not always the case. You know, you need to look on an individual basis. These people need to be policed. Some government departments where when you insulate a property, your house should have a change of planning on that particular property. If you don’t inform building control that you have changed the fabric of your building, you are against building and planning law. But the people that were meant to inform the local planning authority that they have changed the fabric of the building was the guarantee companies. And if the guarantee companies haven’t done that within 24 hours, they are actually committing a criminal offense. So our housing stock needs to be looked at at what we’ve done previously and what we’re looking at now. And yes, when we look at it now it’s a lot better because we are trying to put things in place that didn’t exist when we first started that down these energy schemes 20 odd years ago. Plus you know, we are actually, there are retrofit coordinators, retrofit designers who are looking at those houses now. But we still have, haven’t changed some of the methodologies for these installations and these types of products. And we are, I think we are restocking the shelves for me to clear in years to come.
