WEBVTT - The Resident Builder podcast: June 30, 2024 0:00:06.855 --> 0:00:10.055 You're listening to the Resident build Up podcast with Peter 0:00:10.175 --> 0:00:12.015 wolf Camp from US talks. 0:00:11.775 --> 0:00:18.575 At b Oom Stretcher of the hard Time. We took 0:00:18.615 --> 0:00:27.735 a heart left, but we're all right, yeah sure cantra 0:00:28.455 --> 0:00:30.575 so put love. 0:00:30.415 --> 0:00:36.175 Goodie, but we do this ride is so something's ever 0:00:36.295 --> 0:00:36.975 gonna move it. 0:00:37.055 --> 0:00:40.415 When the bones are good, rest stone at you, the 0:00:40.655 --> 0:00:41.695 pain of field. 0:00:42.175 --> 0:00:43.415 That's good, shadow that. 0:00:43.575 --> 0:00:46.615 It work this U and I remained. 0:00:46.815 --> 0:00:54.055 So when they ate a crack in the foundation, Debbiano, 0:00:54.215 --> 0:00:58.335 the stone well prison for the over bound, we stayed. 0:00:59.055 --> 0:01:02.735 The hot stone fall in the bones are good. 0:01:05.135 --> 0:01:08.775 Mm we call it the. 0:01:11.335 --> 0:01:16.255 Baby you even. 0:01:18.015 --> 0:01:26.815 Bood drive way plany. 0:01:26.895 --> 0:01:30.495 But the wolves came when. 0:01:31.935 --> 0:01:33.535 We standing. 0:01:43.575 --> 0:01:45.535 Well, A very good morning and welcome along to the 0:01:45.535 --> 0:01:48.695 Resident Builder on Sunday. You're with Peak wolf Camp. That's 0:01:48.695 --> 0:01:51.415 me the Resonant Builder, and we're here to talk about 0:01:51.455 --> 0:01:55.135 all things building and construction. And that's her fairly broad 0:01:55.255 --> 0:01:58.535 sort of base on which to build a show, because 0:01:58.535 --> 0:02:02.415 we can talk about literally building, the mechanics of it, 0:02:02.535 --> 0:02:05.815 the actual physical activity involved in it, what you need, 0:02:05.855 --> 0:02:08.255 the material you need, the trades people you might need 0:02:08.295 --> 0:02:10.695 to do it. We can also talk about I guess 0:02:10.495 --> 0:02:14.615 that sort of structural framework in terms of legislation, so 0:02:14.695 --> 0:02:18.215 there are rules and guidelines around what you can build 0:02:18.255 --> 0:02:20.175 where you can build it. A lot of that is 0:02:20.455 --> 0:02:22.695 actually up for grabs at the moment in the sense 0:02:22.735 --> 0:02:25.375 that there are moves of foot at a government level 0:02:25.455 --> 0:02:29.055 to change the types of buildings, the size of buildings 0:02:29.095 --> 0:02:32.375 that we might be able to build without necessarily requiring 0:02:32.415 --> 0:02:36.375 a building consent. We had quite a conversation about that 0:02:36.815 --> 0:02:39.375 last week on the show, and then during the week 0:02:39.975 --> 0:02:44.255 obviously little pieces of information and little discussions happen, particularly 0:02:44.335 --> 0:02:46.815 around that topic. And I've been part of a couple 0:02:46.855 --> 0:02:51.655 of those, number of them that were held while Building 0:02:51.775 --> 0:02:56.055 z which is a sort of trade based building expo 0:02:56.135 --> 0:03:00.335 that was on what was it Tuesday Wednesday here in 0:03:00.375 --> 0:03:02.615 Auckland was on and there I went to a couple 0:03:02.655 --> 0:03:05.375 of seminars which were interesting in themselves, and then had 0:03:05.415 --> 0:03:07.375 an opportunity to cat up with a whole bunch of 0:03:07.375 --> 0:03:10.495 people that some I knew, some that I was introduced to, 0:03:10.935 --> 0:03:13.455 and certainly front of mine for a lot of people 0:03:13.615 --> 0:03:18.295 was this new proposed legislation or the draft document, the 0:03:18.335 --> 0:03:21.895 discussion document that's out at the moment around hey, look 0:03:22.015 --> 0:03:25.455 what about if we removed the requirement to get a 0:03:25.455 --> 0:03:29.775 building consent for buildings a granny flat up to sixty 0:03:29.935 --> 0:03:34.215 square meters, only one of them per property, etc. Etc. Etc. 0:03:34.535 --> 0:03:36.975 So there's some interesting stuff in that as well. We 0:03:37.015 --> 0:03:39.135 can talk about that, but we can also talk about 0:03:39.375 --> 0:03:42.735 the practicalities. What are you what are your projects at 0:03:42.735 --> 0:03:45.095 the moment, What tasks do you want to try and 0:03:45.135 --> 0:03:48.855 get done. I think I mentioned that I had one, 0:03:49.135 --> 0:03:52.455 well one of a number of jobs on my list 0:03:52.495 --> 0:03:54.655 as well, which, to be fair, I didn't get round 0:03:54.655 --> 0:03:57.135 to this week. It's on the list for tomorrow. I'll 0:03:57.135 --> 0:04:00.215 definitely go and sort out a floorboard that's developed a 0:04:00.295 --> 0:04:03.735 split in it alongside an addition, so that'll be a 0:04:03.735 --> 0:04:07.015 little bit of crawling around underneath the floor to do. 0:04:07.255 --> 0:04:09.015 I presume I'm going to have to do some solid 0:04:09.015 --> 0:04:12.055 blocking underneath it, and then I figured out a way 0:04:12.095 --> 0:04:15.295 of sort of repairing the floorboard without taking it out. 0:04:15.655 --> 0:04:17.375 To be fair, I'm just going to fill it full 0:04:17.415 --> 0:04:20.415 of a POxy. But it's kind of my working plan 0:04:20.495 --> 0:04:22.975 at this stage. See that's part of the process as well. 0:04:23.175 --> 0:04:25.495 You have to plan the work that you need to do. 0:04:25.655 --> 0:04:28.175 I popped into the Razine store picked up some of 0:04:28.215 --> 0:04:30.655 the repair care product that I use quite a lot 0:04:31.735 --> 0:04:35.415 in preparation for this little job tomorrow. And because it's floorboards, 0:04:35.455 --> 0:04:38.135 I'll make sure I put my kneepads in the in 0:04:38.175 --> 0:04:40.495 the truck before I head off to work tomorrow as well. 0:04:40.615 --> 0:04:42.695 So if you've got a project on oh, eight hundred 0:04:42.815 --> 0:04:44.975 eighty ten eighty is the number to call. If you 0:04:45.015 --> 0:04:46.935 would like to text you, I'm more than welcome to 0:04:46.935 --> 0:04:50.535 do exactly that. It is nine two nine two. And 0:04:50.575 --> 0:04:52.855 if you'd like to send me an email, You're welcome 0:04:52.895 --> 0:04:56.055 to do that as well. It's Pete at newstalksb dot 0:04:56.095 --> 0:05:00.535 co dot nz. So Pete at newstalksb dot co dot ENZ. 0:05:01.535 --> 0:05:05.255 Happy happy Matariki to you as well. A beautiful day 0:05:05.335 --> 0:05:07.815 in this part of the country anyway, to celebrate Mantadiki 0:05:07.975 --> 0:05:11.815 on Friday. So a nice long weekend with some really 0:05:11.895 --> 0:05:16.095 lovely weather is a lovely bonus at this time of year. 0:05:16.295 --> 0:05:18.415 If you've got a project that you'd like to talk about, Oh, 0:05:18.495 --> 0:05:20.615 eight hundred and eighty ten eighty is the number to call. 0:05:20.655 --> 0:05:23.135 The lines are open. We're going to have a couple 0:05:23.135 --> 0:05:26.415 of guests, actually one guest coming into the studio later 0:05:26.455 --> 0:05:29.015 on in the program. So now's a really good time 0:05:29.055 --> 0:05:31.775 to call because we're going to, like I say, we're 0:05:31.775 --> 0:05:34.735 going to have those guests. Bryce McDermott, who I bumped 0:05:34.775 --> 0:05:36.655 into at build en Z. He was working on the 0:05:36.735 --> 0:05:40.055 razine stand and we had a brief opportunity for a 0:05:40.175 --> 0:05:43.335 quick face to face catch up. Given that he's contributed 0:05:43.375 --> 0:05:48.655 to this show for almost ten years, it was nice 0:05:48.695 --> 0:05:50.415 to sort of catch up with him in person, a 0:05:50.535 --> 0:05:53.095 bit of a chat and discuss a few bits and pieces. 0:05:53.255 --> 0:06:00.655 Bryce will be with us. I'm just trying to figure 0:06:00.655 --> 0:06:02.575 out this next text that came through how I'll come 0:06:02.615 --> 0:06:04.975 to that in a minute. So Bryce will be with 0:06:05.055 --> 0:06:07.935 us from seven forty five. Take your painting questions, your 0:06:07.975 --> 0:06:11.735 specific painting questions during the morning, and I'll present those 0:06:11.735 --> 0:06:14.135 two him at seven forty five this morning and then 0:06:14.215 --> 0:06:18.495 after eight o'clock. One thing that I realized during the 0:06:18.575 --> 0:06:21.135 last couple of weeks is obviously we have a new 0:06:21.135 --> 0:06:24.375 sponsor on the show. It's lightfol Solar, and I was thinking, gosh, 0:06:24.455 --> 0:06:26.255 I wonder if in the last ten years of the 0:06:26.295 --> 0:06:30.455 show have we ever actually specifically talked about solar as 0:06:30.495 --> 0:06:33.575 in solar panels and solar power. And to be fair, 0:06:33.655 --> 0:06:37.535 I don't know that we actually ever have as one 0:06:37.535 --> 0:06:39.975 of our experts on the show. Anyway, I'm going to 0:06:39.975 --> 0:06:43.855 remedy that today Marlon from lightful Solar is going to 0:06:44.295 --> 0:06:46.975 join me here in the studio after eight o'clock and 0:06:47.015 --> 0:06:49.415 we'll be talking about what I'd like to do. Is 0:06:49.455 --> 0:06:54.095 kind of like a basically a solar power one oh one. 0:06:54.615 --> 0:06:57.695 What are they, how do they work, what's involved in 0:06:57.735 --> 0:07:01.415 the installation, how long do they last? What sort of 0:07:01.455 --> 0:07:04.975 power generation can you get off a typical solar array? 0:07:05.295 --> 0:07:07.255 How do you have to look after them? What's the 0:07:07.295 --> 0:07:10.015 advantage of having a battery. You might have a question 0:07:10.095 --> 0:07:12.735 as well, more than welcome if you want to text 0:07:12.775 --> 0:07:16.415 through a question for our solo expert, Marlin from Light 0:07:16.455 --> 0:07:18.815 four Solo, who'll be joining me in the studio at 0:07:18.855 --> 0:07:21.895 eight o'clock this morning, and then of course at eight 0:07:21.895 --> 0:07:23.895 point thirty we're into the garden with the rid climb 0:07:23.935 --> 0:07:27.695 past as usual. So that's my long winded way of saying, 0:07:27.735 --> 0:07:30.175 if you've got a question, call now. Oh eight hundred 0:07:30.455 --> 0:07:32.615 eighty ten eighty is the number to call. Looking forward 0:07:32.655 --> 0:07:35.295 to chatting with you again this morning about all things 0:07:35.335 --> 0:07:38.975 building construction. Actually had a couple of people come up 0:07:39.015 --> 0:07:42.055 to me while I was at Building Z to sort 0:07:42.095 --> 0:07:45.015 of carry on discussions that they'd heard on the radio. 0:07:45.575 --> 0:07:47.535 That might not be the opportunity today, but if you've 0:07:47.575 --> 0:07:50.015 got a question of a building nature, you should call 0:07:50.215 --> 0:07:56.895 right now. Oh eight hundred eighty ten eighty you and 0:07:56.935 --> 0:07:59.455 New STALKSB. If you've got a question of a building nature, 0:07:59.735 --> 0:08:02.335 eight hundred eighty ten eighty is the number to call. 0:08:02.415 --> 0:08:05.415 It is eighteen minutes after six. For those of you 0:08:05.455 --> 0:08:07.175 who are into the foot like I am, and you 0:08:07.255 --> 0:08:10.015 might have seen the posts that I put up. Netherlands 0:08:10.375 --> 0:08:12.455 just talk about give me a heart attack as a fan. 0:08:12.735 --> 0:08:15.535 Managed to get through to the last sixteen, but criky 0:08:15.575 --> 0:08:19.255 they made it hard on themselves. And fabulous game this morning. 0:08:19.295 --> 0:08:23.375 So Switzerland have knocked out Italy defending champions from the game, 0:08:23.415 --> 0:08:26.575 and of course Denmark play Germany. I think in about 0:08:26.615 --> 0:08:30.615 forty minutes time Netherlands play on Tuesday morning. It'll be 0:08:30.615 --> 0:08:33.215 a nice at four o'clock start for me on Tuesday morning. 0:08:33.335 --> 0:08:35.135 Oh w eight one hundred and eighty ten eighty is 0:08:35.175 --> 0:08:37.455 the number to call. Kate A very good morning. 0:08:38.175 --> 0:08:40.815 Good morning Pete, happy not ukey to you and to. 0:08:40.815 --> 0:08:43.815 You indeed, indeed, thank you Pete. 0:08:43.895 --> 0:08:47.935 I'm replacing some joinery in an existing dwelling, and I 0:08:47.975 --> 0:08:52.375 have building consent because it's larger than what was there. Actually, 0:08:52.415 --> 0:08:55.495 it's two dwellings. One of them has HIV and it's 0:08:55.575 --> 0:09:01.095 quite dry. But the existing dwelling in that has single glaze, 0:09:01.655 --> 0:09:06.975 nonfirmly broken. It's nineteen seventies, and I have to put 0:09:06.975 --> 0:09:09.695 in a matching type of joinery, which I won't do. 0:09:09.775 --> 0:09:12.255 I want double blaze, yep, but I don't need to 0:09:12.255 --> 0:09:16.375 do thermally broken. And I'm trying to decide about Lowe. 0:09:17.135 --> 0:09:22.535 One joinery fabricator has suggested that if I put Lowe 0:09:22.895 --> 0:09:27.375 in that dwelling, it's going to increase the amount of 0:09:28.295 --> 0:09:31.575 sort of condensation and moisture on the aluminium because it's 0:09:31.615 --> 0:09:35.575 not thermally broken, and it will push the moisture towards 0:09:35.575 --> 0:09:39.975 the joinery, whereas if I just do double blaze and 0:09:40.055 --> 0:09:43.655 not low E, it's not going to have that effect. 0:09:43.815 --> 0:09:44.975 I'm quite confused. 0:09:47.055 --> 0:09:51.935 It's a fascinating I can sort of understand the logic 0:09:52.215 --> 0:09:56.015 behind the conclusion that they've reached in presenting you with 0:09:56.055 --> 0:10:03.775 that summary. Let's say, so that's true. Interesting, I actually 0:10:03.815 --> 0:10:06.935 did a little I didn't experiment this week like proper 0:10:06.975 --> 0:10:12.775 science using and showing the difference between single glazing and 0:10:12.935 --> 0:10:16.975 double glazing. So we had this little booth that had 0:10:17.015 --> 0:10:21.495 two heat lamps, so identical heat lamps in adjoining booths, right, 0:10:21.575 --> 0:10:24.495 separated by a petition, and in front of each of 0:10:24.535 --> 0:10:27.935 them we could put in different types of glass. And 0:10:27.975 --> 0:10:30.575 then in front of that. So outside of this little 0:10:30.575 --> 0:10:36.655 contraption was a radiometer, which is a little glass bubble 0:10:36.735 --> 0:10:40.815 basically with a fan in it, and when heat hits 0:10:40.935 --> 0:10:44.535 the blade of the fan, it's reflective and it will 0:10:44.775 --> 0:10:48.135 generate energy and that will get the blades it's four 0:10:48.175 --> 0:10:51.815 blades in this little fan to spin like an animometer, right, 0:10:51.855 --> 0:10:53.935 so like a little wind vane if you've have seen 0:10:53.935 --> 0:11:00.215 them spinning, and so they would both be still like, 0:11:00.335 --> 0:11:03.055 not moving. Then you'd turn on the heat lamps and 0:11:03.095 --> 0:11:06.215 then you'd see the rate at which each one spun 0:11:06.815 --> 0:11:08.975 depending on how much heat was coming through the glass. 0:11:09.055 --> 0:11:09.255 Right. 0:11:09.615 --> 0:11:11.375 And one of the pieces of glass that we had 0:11:11.375 --> 0:11:14.615 in there, it was some high performance double glazing, which 0:11:14.655 --> 0:11:19.775 included low E so and E is emissivity, which is 0:11:19.855 --> 0:11:24.375 the way in which heat transfers through the glass, right, 0:11:24.455 --> 0:11:28.415 So if you get low emissivity, it reduces the amount 0:11:28.455 --> 0:11:31.855 of heat transfer through the glass. And then you add 0:11:31.895 --> 0:11:34.775 that to double glazing, which just by having two pieces 0:11:34.815 --> 0:11:39.135 of glass separated by a spacer creates that effect anyway, 0:11:39.135 --> 0:11:43.935 because obviously heat moving through two pieces of glass goes 0:11:43.935 --> 0:11:48.335 through the first part, hits the spacer that reduces the emissivity, 0:11:49.135 --> 0:11:51.335 and then it has to go through another piece of glass. 0:11:51.335 --> 0:11:54.015 But if you up the speck on that by going 0:11:54.055 --> 0:11:58.455 low E, you get even less emissivity, i Less heat 0:11:58.495 --> 0:12:02.775 transfer through the glass. And in what your joiner is 0:12:02.815 --> 0:12:07.375 saying is okay, if not a lot else chain and 0:12:07.415 --> 0:12:10.815 we put low E glass into this one single frame, 0:12:10.935 --> 0:12:17.935 and we've still got conventional aluminium jowinery, and the distinction 0:12:18.095 --> 0:12:22.415 being new aluminium jowinery most likely needs to be thermally 0:12:22.455 --> 0:12:26.095 broken in order to comply with H one standards of 0:12:26.215 --> 0:12:31.175 the Building Code because they've increased. But if you're doing 0:12:31.215 --> 0:12:35.775 only replacing one or two windows, you know, like practically 0:12:35.855 --> 0:12:37.935 I would say it's a little bit absurd to get 0:12:38.015 --> 0:12:41.895 you to put in thermally broken jowinery and low E 0:12:42.295 --> 0:12:44.815 in that one window when you don't have it anywhere 0:12:44.855 --> 0:12:47.495 else in the house. Now you could do it because 0:12:47.615 --> 0:12:49.895 you go, well, maybe later on I'll change it, and 0:12:49.935 --> 0:12:52.415 I don't want to have to change the joinery again 0:12:52.535 --> 0:12:58.415 later on. But realistically, changing one piece of joinery in 0:12:58.535 --> 0:13:01.855 a total building envelope is not going to make a 0:13:01.855 --> 0:13:05.935 significant change to the overall performance of the building. Those 0:13:05.975 --> 0:13:08.895 windows will perform better, but the rest will continue to 0:13:08.935 --> 0:13:11.895 perform as they are. And I suppose what he's saying 0:13:11.895 --> 0:13:14.095 there is to go Okay, if you put low eglass 0:13:14.135 --> 0:13:16.855 in there, heat will still want to do what heat does, 0:13:16.935 --> 0:13:21.655 which is equalize. So if it's warm inside cold outside, 0:13:21.935 --> 0:13:24.495 it will want to equalize and it will find a pathway, 0:13:24.615 --> 0:13:29.095 and that pathway will become your standard non thermally broken 0:13:29.215 --> 0:13:33.655 aluminium and that's where you'll see condensation. But it feels 0:13:33.695 --> 0:13:38.375 like a sort of worse and worser type of situation. 0:13:38.615 --> 0:13:44.615 You know that. Okay, So you get a choice basically, 0:13:44.855 --> 0:13:47.175 do I want some condensation on my glass or do 0:13:47.215 --> 0:13:50.455 I want it on the aluminium? And if you want 0:13:50.495 --> 0:13:54.615 to sort of share the deficit around, then you will 0:13:54.655 --> 0:14:01.975 go for standard double glazing plus and your existing unbroken 0:14:02.535 --> 0:14:05.655 standard aluminium jowinery, and then you'll get a little bit 0:14:05.655 --> 0:14:08.175 of condensation on both of them. If you went for 0:14:08.175 --> 0:14:11.135 lower glass, then you'll have more condensation on the aluminium 0:14:11.615 --> 0:14:12.975 and less on the glass. 0:14:14.015 --> 0:14:14.975 Oh that's really helpful. 0:14:14.975 --> 0:14:18.575 Actually, I mean sorry, that seems like not quite a long. 0:14:18.735 --> 0:14:20.055 I mean there's a little bit in that, and I 0:14:20.095 --> 0:14:24.415 can I mean, look, I would like the performance difference. 0:14:24.495 --> 0:14:28.335 And again I have done some presentations recently we have 0:14:28.415 --> 0:14:30.975 actually drilled down into the detail, right, so you know 0:14:31.015 --> 0:14:35.695 what's the difference between. So, by way of example, if 0:14:35.735 --> 0:14:41.975 you had a piece of single glazed standard aluminum joinery 0:14:42.495 --> 0:14:45.735 and you compared that same window to one that was 0:14:46.575 --> 0:14:50.095 either thermly broken or if you had timber or uPVC 0:14:50.295 --> 0:14:53.695 as the frame, and then you had high performing low 0:14:53.735 --> 0:14:59.015 eglass in it, the effectiveness of the high performance joinery 0:14:59.215 --> 0:15:03.655 versus the standard is almost a factor of ten. It's 0:15:03.655 --> 0:15:07.175 almost ten times more efficient than what you would have 0:15:07.255 --> 0:15:10.375 in So we know that it works. And again, going 0:15:10.375 --> 0:15:13.375 back to my little experiment, which thankfully we filmed and 0:15:13.415 --> 0:15:17.695 that'll be available online sometime in the future, you can 0:15:18.335 --> 0:15:20.935 you can measure what you can't see, which is which 0:15:21.015 --> 0:15:24.295 was the benefit of doing this little experiment, right, because 0:15:24.295 --> 0:15:27.935 we go to people, Okay, well, if you upspec your 0:15:28.255 --> 0:15:32.335 glazing the glass in your windows there is a benefit. 0:15:32.455 --> 0:15:35.175 And then you go, well, hang on, glass is glass, right, 0:15:35.215 --> 0:15:37.055 I look through it. How do I know that it's 0:15:37.095 --> 0:15:37.815 actually working? 0:15:38.175 --> 0:15:38.335 Now? 0:15:38.375 --> 0:15:40.735 Well, here we can show you. This is what happens 0:15:40.775 --> 0:15:43.855 in a physical sense when heat transfers through the glass. 0:15:43.935 --> 0:15:48.415 It's getting that little radiometer to spin way faster than 0:15:48.415 --> 0:15:49.215 the one next to it. 0:15:50.495 --> 0:15:54.815 I'm interested in keeping keeping the heat in. Yeah, a 0:15:55.535 --> 0:15:59.215 little bit of condensation on the joint on the aluminium 0:15:59.255 --> 0:16:01.775 doesn't room it, but the glass when it gets commensasion 0:16:01.815 --> 0:16:04.375 on it is quite annoying. But I am planning probably 0:16:04.535 --> 0:16:07.775 you know, five years, maybe I might do some retrofit 0:16:07.895 --> 0:16:11.895 double glazing on the other joinery in the drying. Now, 0:16:12.135 --> 0:16:14.895 these there's two dwellings involved, so one of them tends 0:16:14.935 --> 0:16:18.175 to get moisture than the other. The one with the 0:16:18.335 --> 0:16:20.655 HIV doesn't seem to get moist at all. And I'm 0:16:20.695 --> 0:16:24.975 thinking that ought to have the low e because that's 0:16:25.015 --> 0:16:27.855 just a small window going to a large branch lader 0:16:27.975 --> 0:16:30.455 now and there's not many windows and the rest of it. 0:16:30.855 --> 0:16:33.415 So I think it makes sense there because that's going 0:16:33.495 --> 0:16:34.335 to be the majority. 0:16:35.055 --> 0:16:37.895 But in your case, then the benefit of the HIV 0:16:38.135 --> 0:16:43.135 is that you've got air movement, right, and that helps 0:16:43.415 --> 0:16:48.175 raise the temperature a little bit. So again, condensation is 0:16:48.735 --> 0:16:54.495 moisture laden air collecting on a cool surface, right, So 0:16:54.535 --> 0:16:57.295 if you've got single glaze single glazing like most of 0:16:57.335 --> 0:17:00.895 us do at home, that inside surface of the glass 0:17:00.935 --> 0:17:04.495 will cool down because of course the outside temperature. When 0:17:04.495 --> 0:17:06.015 I drove to work this morning, I looked at the 0:17:06.095 --> 0:17:09.855 dam on the MASDA and it was nine degrees outside, right, 0:17:09.895 --> 0:17:12.655 So it's not cold inside my house. I glanced at 0:17:12.695 --> 0:17:16.215 the thermometer on the way out. It's probably about eighteen 0:17:16.255 --> 0:17:20.935 degrees right, So you've got nine degrees outside eighteen degrees inside. 0:17:21.055 --> 0:17:24.335 The point at which those two temperatures are meeting is 0:17:24.375 --> 0:17:29.015 the glass, and so the world wants to equalize, and 0:17:29.055 --> 0:17:32.175 so my glass is going to get cold because it's 0:17:32.175 --> 0:17:36.095 colder outside than inside. And if I didn't keep the 0:17:36.135 --> 0:17:39.535 heat up, if the house wasn't relatively dry, then I'd 0:17:39.575 --> 0:17:43.695 start to see condensation on those windows. That's where it meet. 0:17:43.775 --> 0:17:47.135 That's where it's evident. There's always moisture in the air, 0:17:47.255 --> 0:17:50.295 but when it hits a cold surface, that's where it commensates. 0:17:52.375 --> 0:17:54.335 And in some cases you know, if you go into 0:17:54.375 --> 0:17:58.175 some houses that have little or no insulation in the wall, 0:17:58.375 --> 0:18:00.615 then the wall itself, if you put your eaving you 0:18:00.615 --> 0:18:02.495 can feel it. Sometimes you put your hand on the 0:18:02.535 --> 0:18:05.215 wall and you can feel that the wall is cold. 0:18:06.335 --> 0:18:09.135 And so in those situations you'll actually get condensation on 0:18:09.175 --> 0:18:12.175 the on the walls, on the plaster board walls, not 0:18:12.495 --> 0:18:13.335 just on the glass. 0:18:16.055 --> 0:18:20.535 Right, So to summarize, and I'm just trying to I'm 0:18:20.575 --> 0:18:23.335 trying to make sure I get the get the right 0:18:23.375 --> 0:18:25.655 information from me here because it's a little Yeah, sure, 0:18:26.095 --> 0:18:30.095 if I put low e, it's going to reduce condensation 0:18:30.775 --> 0:18:33.735 on the glass, but it's going to push it to 0:18:34.015 --> 0:18:37.135 where the moist to where the temperature can equalize, which 0:18:37.215 --> 0:18:38.055 is the aluminium. 0:18:39.095 --> 0:18:41.495 Well, I think that's what the guy is telling you, 0:18:41.535 --> 0:18:48.735 and I can see a certain logic in that. My 0:18:48.895 --> 0:18:52.615 sense is if if there's it often comes down to 0:18:52.695 --> 0:18:55.535 dollars as well. Right, So you know, is it worth 0:18:55.575 --> 0:18:58.095 investing in the low e glass, which we know is 0:18:58.655 --> 0:19:01.575 better than standard double glazing, which is then better than 0:19:02.135 --> 0:19:05.815 good old fashioned single glazing. And if you were thinking 0:19:05.815 --> 0:19:09.255 of doing more work in the future, I suppose investing 0:19:09.255 --> 0:19:12.655 in the upgrade is an investment in the future as well. 0:19:13.135 --> 0:19:15.735 If you were quite clear that you were never going 0:19:15.775 --> 0:19:17.935 to do anything else to the rest of the house, 0:19:18.375 --> 0:19:20.735 then I would say put the double glazing in, because 0:19:20.775 --> 0:19:22.935 you'll get the benefit from that, but it may not 0:19:23.295 --> 0:19:26.495 overall be worth spending the money to upgrade to low 0:19:26.615 --> 0:19:31.015 E And that's just being reasonable and practical. You know 0:19:31.135 --> 0:19:33.255 there is a benefit to doing it, but you've got 0:19:33.255 --> 0:19:35.615 to look at the overall project as well and be 0:19:35.695 --> 0:19:39.335 realistic about what you're going to achieve by doing it. 0:19:39.695 --> 0:19:43.855 And again, the reason that doing one part of an 0:19:43.935 --> 0:19:47.375 overall thermal envelope is for exactly that reason. What we're 0:19:47.415 --> 0:19:51.055 trying to create is a thermal envelope, right, So we 0:19:51.095 --> 0:19:55.495 want to ensure that we're trapping heat inside our houses 0:19:55.855 --> 0:20:05.055 and keeping cold out enveloping the space that we inhabit. Yeah, yeah, 0:20:05.135 --> 0:20:06.295 because what are your walls like? 0:20:06.295 --> 0:20:10.855 So one of them has insulation in because it was 0:20:10.895 --> 0:20:15.775 built in two thousand and six, and that has four 0:20:15.775 --> 0:20:20.615 other windows, but one of the windows is in question, 0:20:20.815 --> 0:20:22.535 and then it's going to have a large ranch slider 0:20:22.815 --> 0:20:25.695 and then there are or there's another ranch slider which 0:20:25.775 --> 0:20:27.855 is not double blaze, so that has a lot of 0:20:27.975 --> 0:20:32.615 existing joinery, and it has a heat pump and it's insulated. 0:20:33.215 --> 0:20:37.655 The other dwelling does not have insulation. It's nineteen seventies. 0:20:38.015 --> 0:20:40.495 It has a heat pump. But this is pretty much 0:20:40.535 --> 0:20:43.255 the only piece of joinery in the room. There are 0:20:43.295 --> 0:20:47.935 two adjacent rooms with very small windows, and I'm thinking 0:20:47.975 --> 0:20:51.935 that one should have the low e because it's the 0:20:51.975 --> 0:20:54.855 major piece of joinery and to upgrade the others isn't 0:20:54.855 --> 0:20:55.935 going to be much in the future. 0:20:56.135 --> 0:21:00.055 Yeah, So it becomes a percentage. It becomes a percentage game, right, 0:21:00.295 --> 0:21:02.895 And that's why you know, as we get more and 0:21:02.895 --> 0:21:05.215 more of our houses have more and more joinery in it, right, 0:21:05.295 --> 0:21:08.215 we want the use and we want that connection to outside, 0:21:08.215 --> 0:21:10.855 so we team we have Traditionally, if you think about 0:21:11.335 --> 0:21:15.615 older buildings, they don't have as much space taken up 0:21:15.655 --> 0:21:19.255 by joinery whereas we do today. So again, if you're 0:21:20.135 --> 0:21:22.295 you might say, look, twenty five percent of my wall 0:21:23.295 --> 0:21:26.775 is glazing, in which case it makes sense to make 0:21:26.815 --> 0:21:30.575 that glazing as thermally efficient as possible because it's so 0:21:30.655 --> 0:21:34.895 much of a wall. So I'm circling back, and I 0:21:34.895 --> 0:21:37.695 think you were heading there as well. If it's if 0:21:37.775 --> 0:21:40.135 in your case, the ranch slider is a big part 0:21:40.135 --> 0:21:43.055 of that exterior surface, then it would pay to make 0:21:43.095 --> 0:21:45.415 that as efficient as possible, which is the low e. 0:21:46.775 --> 0:21:49.455 Yeah, what I felt was not efficient was to go 0:21:49.575 --> 0:21:52.655 with theirmally broken because even if I upgrade later on 0:21:52.695 --> 0:21:54.335 the rest of the joinery, it's never going to be 0:21:54.335 --> 0:21:59.015 somally broken. The retrofited, double glazed correct. And the cost 0:21:59.055 --> 0:22:02.655 difference there thermally broken was massive. Is that much for 0:22:02.695 --> 0:22:05.455 the low e? It isn't. I want to make the decision. 0:22:05.695 --> 0:22:08.055 Okay, it sounds like you're on track, or hopefully we've 0:22:08.095 --> 0:22:12.255 discussed you know, this is where these are permutations, right, 0:22:12.295 --> 0:22:14.135 This is a little bit of this and a little 0:22:14.135 --> 0:22:16.095 bit of that. But the great thing about I found 0:22:16.135 --> 0:22:18.895 for our discussion is that you're you're obviously aware that 0:22:18.935 --> 0:22:22.855 you've got all of these different components that when combined, 0:22:23.095 --> 0:22:28.095 give you better performance. But you know, we can't focus 0:22:28.135 --> 0:22:31.255 on sort of a one fixed solution like typically if 0:22:31.775 --> 0:22:34.455 if we're after warm, dry comfortable, we've got to be 0:22:34.495 --> 0:22:37.615 looking at all of these elements that combine in our 0:22:37.895 --> 0:22:41.375 houses to create warm, dry comfortable, and it's it's never 0:22:41.495 --> 0:22:42.215 just one thing. 0:22:43.615 --> 0:22:45.535 No I am aware of that couldn't been listening to. 0:22:45.495 --> 0:22:46.295 You for a long time. 0:22:48.455 --> 0:22:49.215 Very kind of you. 0:22:49.175 --> 0:22:51.575 To say, you make a lot of sense. 0:22:51.615 --> 0:22:56.975 Have a great day, you too, very much. Pleasure all 0:22:56.975 --> 0:22:59.895 the best bother that your news talks, he'd be, yes, 0:23:00.095 --> 0:23:02.615 it does. I suppose this is one of the things 0:23:02.655 --> 0:23:05.655 that I actually really really love about buildings is that 0:23:05.735 --> 0:23:11.535 they are, in a sense incredibly simple. Buildings for us 0:23:11.535 --> 0:23:16.535 as human beings are shelter, right, a basic human requirement 0:23:16.775 --> 0:23:19.175 for us to be able to thrive, let's say, is 0:23:19.215 --> 0:23:23.015 to have shelter. And then from the basic requirement for 0:23:23.095 --> 0:23:27.015 shelter through to actually being really really healthy and good 0:23:27.055 --> 0:23:30.215 for us, warm, dry, comfortable, then we start to get 0:23:30.535 --> 0:23:34.975
