That's with three Pete off 0:01:48.695 --> 0:01:52.015 Camp and we are here too. Basically, well, talk about 0:01:52.055 --> 0:01:54.815 your place. So if you've got a little project on, 0:01:55.375 --> 0:01:58.335 maybe you're doing some alterations, maybe you're doing some renovations, 0:01:58.375 --> 0:02:01.175 maybe you're just looking to the you know, the days 0:02:01.175 --> 0:02:04.095 are getting a bit shorter, it's a little bit cooler. 0:02:04.655 --> 0:02:06.215 I was going to say the rain has started, but 0:02:07.175 --> 0:02:10.095 realistically it hasn't anyway, not in this part of the country, 0:02:10.695 --> 0:02:12.895 and we're kind of getting a bit desperate for it 0:02:12.935 --> 0:02:15.615 to be fair. But we're thinking about, you know, what's 0:02:15.615 --> 0:02:17.255 it going to be like when the rain comes and 0:02:17.295 --> 0:02:19.815 the wind comes, and have we sorted out that window 0:02:19.855 --> 0:02:23.895 that doesn't quite close, or perhaps some downpipes that are 0:02:24.095 --> 0:02:26.375 not quite working as well as they should. So if 0:02:26.415 --> 0:02:29.335 you've got a project on and you'd like to talk 0:02:29.375 --> 0:02:32.055 about it, well, I'd love to listen. Oh eight hundred 0:02:32.135 --> 0:02:34.775 eighty ten eighty is the number to call nine two 0:02:34.855 --> 0:02:38.735 nine two or zbzb from the text machine. That'll get 0:02:38.735 --> 0:02:41.295 you straight into the studio. And I've just logged into 0:02:41.295 --> 0:02:43.975 my email, so if you would like to send an email, 0:02:44.335 --> 0:02:47.735 it is Pete at newstalksb dot co dot nz. So 0:02:47.855 --> 0:02:51.655 Pete p E t E at newstalksb dot co dot nz. 0:02:51.815 --> 0:02:54.015 I trust you've had a good week. If you've been 0:02:54.055 --> 0:02:57.055 doing projects, then I trust you've had a productive week. 0:02:58.415 --> 0:03:00.815 You know, there's there's kind of a satisfaction that comes 0:03:00.855 --> 0:03:06.255 with undertaking the task, but also that sense of satisfaction, right, 0:03:06.695 --> 0:03:09.375 I wanted to do it. I've done it, you know, 0:03:09.415 --> 0:03:12.015 I can move on to the next task. I was 0:03:12.055 --> 0:03:14.295 reminding myself of that yesterday as I was in the 0:03:14.295 --> 0:03:18.375 workshop in the late afternoon priming. What have I got 0:03:18.415 --> 0:03:23.135 about one hundred and forty lineal meters of one fifty 0:03:23.575 --> 0:03:26.775 x one fifty x twenty five tongue and groove decking, 0:03:26.855 --> 0:03:30.175 So it's h three point two treated. The guys. I 0:03:30.295 --> 0:03:32.775 ordered it a little while ago, and the guys went, oh, yeah, okay, 0:03:32.815 --> 0:03:35.135 he obviously wants it really soon. So when I went 0:03:35.175 --> 0:03:36.695 to pick it up the other day, because I didn't 0:03:36.695 --> 0:03:38.575 actually need it as soon as I thought I did, 0:03:39.575 --> 0:03:42.495 that's another story, isn't it. It turns out that it 0:03:42.575 --> 0:03:45.295 wasn't pre primed. So I was down at Razine yesterday, 0:03:45.415 --> 0:03:49.495 got a tin of four liter ten of oil based primer, 0:03:50.335 --> 0:03:52.295 set myself up a little jig because of course, if 0:03:52.335 --> 0:03:55.135 you're priming, pre priming tongue and groove, you've got to 0:03:55.135 --> 0:04:00.175 get into the groove and around the tongue and then well, 0:04:00.415 --> 0:04:05.815 podcast in, yeah, powards in brush ready, tin ready, and 0:04:05.935 --> 0:04:08.455 we're in it in the workshop, little production line, going 0:04:08.775 --> 0:04:11.855 to do that. So and actually speaking about painting, because 0:04:11.855 --> 0:04:14.375 I was talking a good mate Jay from Razine on 0:04:14.415 --> 0:04:17.775 the Friday, just making sure I was using the right 0:04:17.775 --> 0:04:19.855 product and the right application. So I'm going to do 0:04:20.015 --> 0:04:21.975 an oil based undercoat, then I'm going to do a 0:04:22.015 --> 0:04:24.775 code of quick dry, and then once the decking is laid, 0:04:25.055 --> 0:04:27.095 which should be in a couple of weeks hopefully, then 0:04:27.495 --> 0:04:30.055 I'll go over the top with my top coats, which 0:04:30.095 --> 0:04:33.135 will be water borne. Good news, as he gave me 0:04:33.175 --> 0:04:34.935 all the advice, I asked him all the questions, so 0:04:35.015 --> 0:04:36.815 I don't need to ask him in question today, but 0:04:36.895 --> 0:04:39.375 there is an opportunity for you to ask him in question. 0:04:39.735 --> 0:04:43.175 So at around seven twenty this morning, Jay from Razine 0:04:43.215 --> 0:04:46.015 will be joining us, and if you've got a question 0:04:46.295 --> 0:04:50.495 of painting nature, then please text those through. So that's 0:04:50.575 --> 0:04:53.655 nine two, nine to two. We'll line them up and 0:04:53.735 --> 0:04:56.935 we'll race through a whole series of your questions around 0:04:56.975 --> 0:04:59.655 painting with Jay at about seven thirty this morning. But 0:04:59.815 --> 0:05:03.415 right now it is a general opportunity to talk all 0:05:03.495 --> 0:05:07.575 things building and construction. I may have me last week, 0:05:07.615 --> 0:05:11.415 and it's absolutely true that there's a vast number, seemingly 0:05:11.855 --> 0:05:15.695 a series of events and announcements on the way from 0:05:15.975 --> 0:05:19.695 the Government with regard to self certification, with regard to 0:05:20.255 --> 0:05:22.935 sort of an investigation or a little bit of clarity 0:05:22.975 --> 0:05:26.815 around how long it takes building Consent Authorities bcas to 0:05:27.055 --> 0:05:29.815 process building consents and what can be done to speed 0:05:29.855 --> 0:05:34.895 that process up. There's going to be a couple of 0:05:34.935 --> 0:05:37.615 other announcements on the way as well, so I reached 0:05:37.655 --> 0:05:42.535 out to Chris Pink, the Member Member of Parliament and 0:05:42.695 --> 0:05:46.615 the current Minister for Building and Construction during the course 0:05:46.615 --> 0:05:48.335 of the week, and he's going to join us on 0:05:48.415 --> 0:05:52.215 the show next Sunday for a bit of an interview. Actually, 0:05:52.295 --> 0:05:54.975 very generously, he did offer to come into the studio 0:05:55.055 --> 0:05:57.295 and take some calls, and I thought, well, actually, given 0:05:57.335 --> 0:05:59.255 that there's a number of announcements coming up, we might 0:05:59.295 --> 0:06:02.215 just push that back a month and then we will 0:06:02.255 --> 0:06:05.455 We'll get Chris Pink into the studio and you can 0:06:05.455 --> 0:06:07.735 ask questions of him, but at this stage next week 0:06:07.815 --> 0:06:11.895 it'll just be questions, maybe some text questions, and certainly 0:06:11.935 --> 0:06:14.055 I've got a whole bunch of questions for a brief 0:06:14.055 --> 0:06:17.215 interview with Chris Pink, the Minister next Sunday on the show. 0:06:17.495 --> 0:06:20.335 But right now it is your opportunity, so we to 0:06:20.375 --> 0:06:22.255 be fair. Look, folks, we got off to a slow 0:06:22.295 --> 0:06:25.575 start last week. So if you're listening and you're thinking, God, 0:06:25.615 --> 0:06:27.415 I do have a question and I never get time 0:06:27.455 --> 0:06:30.055 to ask it, now's a perfect time to ring O 0:06:30.135 --> 0:06:32.495 eight one hundred and eighty ten eighty. If you've got 0:06:32.495 --> 0:06:35.215 a question of a building nature, whether it's you know, 0:06:35.495 --> 0:06:38.055 the practical side of things, how do I do this? 0:06:38.655 --> 0:06:42.215 The kind of theoretical in terms of what regulations apply, 0:06:42.375 --> 0:06:47.455 which rules apply? In fact, who was I this week? Oh, 0:06:47.535 --> 0:06:50.215 a couple of events that I went to in talking 0:06:50.255 --> 0:06:54.335 to a young guy who's a former building inspector and 0:06:54.495 --> 0:06:58.495 also building survey now and we got onto talking about 0:06:58.655 --> 0:06:58.935 h one. 0:06:58.975 --> 0:06:59.535 Oh that's right. 0:06:59.575 --> 0:07:02.135 I had an interesting discussion with a guy around tiling 0:07:02.175 --> 0:07:04.655 and tiling showers, and both of us came to the 0:07:04.735 --> 0:07:10.295 conclusion that unfortunately, the legislation is not terribly clear around 0:07:10.735 --> 0:07:14.575 whether when you need a building consent for a tile shower. 0:07:14.975 --> 0:07:17.095 So we can we can talk about that a little 0:07:17.095 --> 0:07:20.295 bit as well on the program. So practical things, theoretical things, 0:07:20.975 --> 0:07:23.535 and maybe some tips and tricks of getting a job 0:07:23.575 --> 0:07:25.775 done just a little bit quicker. I mean, look, it 0:07:25.815 --> 0:07:28.375 was as simple as this. Yesterday, the day before I 0:07:28.415 --> 0:07:30.175 knew that I have to. So I've docked all my 0:07:30.295 --> 0:07:33.415 boards roughly to length, knowing that I'm going to have 0:07:33.455 --> 0:07:35.295 to trim the front edge off once I lay the 0:07:35.295 --> 0:07:38.895 decking boards, I'm going to have to paint the edges 0:07:39.815 --> 0:07:42.015 the tongue and the groove of this tongue groove board. 0:07:42.295 --> 0:07:44.695 So I just made a couple of little brackets, timber 0:07:44.735 --> 0:07:47.215 ones that I have on the bench that I can 0:07:47.255 --> 0:07:49.495 stand the board up in so that I don't have 0:07:49.535 --> 0:07:51.215 to hold it while I'm trying to paint the edge. 0:07:51.335 --> 0:07:53.655 Little things like that. Oh eight hundred, I'll send you 0:07:53.695 --> 0:07:56.215 a photo. Oh eight hundred eighty ten eighty. Let's rip 0:07:56.255 --> 0:07:58.535 into it. The lines are open. My name's people off Camp, 0:07:58.575 --> 0:08:01.375 the resident builder, and we are talking all things building 0:08:01.455 --> 0:08:05.415 and construction. I've got an interesting update too on if 0:08:05.455 --> 0:08:07.775 you recall I mentioned this a couple of times during 0:08:07.975 --> 0:08:10.815 the program. Today. A couple of weeks ago, we had 0:08:10.815 --> 0:08:15.175 the opportunity to talk with Charlotte McEwan from One Tree 0:08:15.255 --> 0:08:20.015 Hill College. They have done a complete rebuild of an 0:08:20.015 --> 0:08:23.295 old Kaina Aura house. So it was a it was 0:08:23.295 --> 0:08:26.175 a house offer development site. They bought it for a 0:08:26.215 --> 0:08:29.375 dollar off Ko had it shipped to one Tree Hill 0:08:29.375 --> 0:08:33.295 College in Auckland the students and some local LBP builders 0:08:33.375 --> 0:08:37.015 and I have to say some tremendous companies that got 0:08:37.055 --> 0:08:40.695 on board with this. They've completely refurbished the house. And 0:08:40.775 --> 0:08:44.295 when I say refurbished, it is now home Star seven, 0:08:44.415 --> 0:08:47.415 so New Zealand Green Building Council home Star seven rated 0:08:47.455 --> 0:08:53.935 house which makes it exceptionally eco friendly and energy efficient. 0:08:54.855 --> 0:08:58.455 And that's going up for sale on Thursday, so check 0:08:58.495 --> 0:09:01.055 it out. Barfat and Thompson would have it on their website. 0:09:01.095 --> 0:09:03.415 You'll find it on trade me as well. It is 0:09:03.455 --> 0:09:07.815 a fantastic event. I'm going to pop along. I don't 0:09:07.895 --> 0:09:09.615 know that I'll put my hand up for it. I'm 0:09:09.655 --> 0:09:12.335 not sure what I would do with a very very 0:09:12.335 --> 0:09:14.975 good three bedroom house, but hey, if you know someone 0:09:14.975 --> 0:09:17.015 who wants one, you should be at the auction on 0:09:17.055 --> 0:09:20.095 set on Thursday four o'clock. Looking forward to that, right, 0:09:20.175 --> 0:09:22.495 let's get amongst it, folks. Oh, eight hundred and eighty 0:09:22.535 --> 0:09:25.135 ten eighty is the number. It is just on six 0:09:25.415 --> 0:09:28.855 fifteen and Tony, a very good morning to you, Good. 0:09:28.615 --> 0:09:30.975 Morning to your again to talk to you again. 0:09:31.135 --> 0:09:31.455 Thank you. 0:09:32.415 --> 0:09:35.615 I've got a question. We had a house that was 0:09:36.335 --> 0:09:38.335 category three, and then we sold it and I bought 0:09:38.375 --> 0:09:43.295 another one of colonial wooden windows. Yes, the thing is, 0:09:43.415 --> 0:09:45.575 before I bought it, people to put it on the 0:09:45.615 --> 0:09:50.615 market just put cheap paint all over the windows. Right now. 0:09:51.335 --> 0:09:53.575 I knew when I bought it it didn't have aluminium, 0:09:53.575 --> 0:09:57.735 but that you can't have everything in life. So I'm 0:09:57.775 --> 0:09:59.615 about at the stage where I need to start doing 0:09:59.655 --> 0:10:02.215 the windows. The windows are all opening and closing. There's 0:10:02.215 --> 0:10:05.055 only one catch broken. I've got to take a bit 0:10:05.095 --> 0:10:08.935 of timber off a couple of the side. Sure, but 0:10:09.815 --> 0:10:12.255 do I need to take all that paint off back 0:10:12.335 --> 0:10:16.695 to the bear timber. My thoughts were that I'd use 0:10:17.455 --> 0:10:23.095 with the shore seal all based and then put a 0:10:23.135 --> 0:10:28.255 good top coat on. Being more than one, would that 0:10:28.335 --> 0:10:29.335 be what I should do? 0:10:30.855 --> 0:10:33.495 I guess the thing that causes me to take a 0:10:33.535 --> 0:10:36.935 breath for a second is that someone's applied perhaps and 0:10:37.375 --> 0:10:40.415 not particularly good paint over the top of existing paint. 0:10:40.535 --> 0:10:41.255 So if you. 0:10:41.215 --> 0:10:43.255 Apply it correct, that's absolutely correct. 0:10:43.335 --> 0:10:45.895 Yeah. So if you then apply another coat, even if 0:10:45.935 --> 0:10:48.855 you use something like shore seal, right, which is to 0:10:48.895 --> 0:10:51.135 be fair, it's more it's a pigmented seala that I 0:10:51.175 --> 0:10:55.575 would typically use on bear or on plaster board surfaces 0:10:55.575 --> 0:10:59.455 that have been painted. I'm I'm more than happy to 0:10:59.455 --> 0:11:01.895 ask jay At in about an hour's time. But I 0:11:01.935 --> 0:11:06.135 would think that the concern is that you will apply 0:11:06.375 --> 0:11:08.655 a coat to the top of a coat that's not 0:11:08.975 --> 0:11:12.655 particularly well adhered, and that eventually that will your top 0:11:12.695 --> 0:11:15.695 coat will peel off with the coat below it. So 0:11:15.935 --> 0:11:18.215 I think at the very least you would want to 0:11:18.895 --> 0:11:22.615 hit all of the windows with like a tungsten scraper 0:11:23.335 --> 0:11:25.735 or possibly even some paint stripper and try and get 0:11:25.815 --> 0:11:28.055 rid of that top coat. You might find that the 0:11:28.055 --> 0:11:32.615 coat underneath is actually reasonably firm, and at that point 0:11:32.695 --> 0:11:35.535 I would give that a primer coat, probably an oil 0:11:35.615 --> 0:11:37.455 based one, and then. 0:11:37.455 --> 0:11:42.695 Go overficient man look. 0:11:42.775 --> 0:11:45.615 I typically have always used sure seal where I've got 0:11:45.735 --> 0:11:49.535 existing plaster board. You know, like let's say you repair 0:11:49.575 --> 0:11:51.575 a section of a wall and you've got some new 0:11:51.615 --> 0:11:53.775 plastering and some new job board, and you've got some 0:11:53.855 --> 0:11:56.575 old plaster board that's already had a coat of paint 0:11:56.615 --> 0:11:59.175 on it. I'll use it in that instance there just 0:11:59.215 --> 0:12:02.855 to bind everything together outside. I typically I'm a little 0:12:02.855 --> 0:12:05.255 bit old fashioned with this. I typically use an oil 0:12:05.335 --> 0:12:10.255 based primer for my timber joinery. You can finish in 0:12:10.335 --> 0:12:13.095 a water born enamel, which is really good and a 0:12:13.095 --> 0:12:17.175 little bit easier to apply for exterior, although saying that 0:12:17.295 --> 0:12:20.815 I typically for my own jobs, I'll often use an 0:12:20.935 --> 0:12:23.455 enamel on my joinery outside as well. 0:12:24.175 --> 0:12:26.655 So oil based, oil based and top coat. 0:12:26.775 --> 0:12:30.535 Yeah, you can get a little bit of yellowing with 0:12:32.535 --> 0:12:35.095 light colors. You know, whites tend to yellow a little bit. 0:12:35.135 --> 0:12:37.975 That's one of the only criticisms of it. I find 0:12:38.015 --> 0:12:44.935 that I'll live with that. Basically, if I want the durability, because. 0:12:44.735 --> 0:12:46.175 I want to do it once, I want to do 0:12:46.215 --> 0:12:49.175 it well. Three quarters of the house I can get to. 0:12:49.495 --> 0:12:52.095 But being a colonial, you've got the timbers in between 0:12:52.135 --> 0:12:55.535 the small pieces of as well, so it's going to 0:12:55.575 --> 0:12:58.215 be quite a job to do it. 0:12:58.255 --> 0:13:01.295 But what it comes down to is that you need 0:13:01.335 --> 0:13:04.175 to be really confident that the surface that you're applying 0:13:04.255 --> 0:13:07.775 your new top coats to is bonding with the timber. 0:13:07.935 --> 0:13:10.775 And if it feels like they've whacked a coat of 0:13:10.815 --> 0:13:12.935 acrylic over the top, maybe they haven't done a great 0:13:12.935 --> 0:13:13.775 deal of preparation. 0:13:14.255 --> 0:13:15.935 Then that none you can see it. 0:13:16.095 --> 0:13:19.455 Yeah, hit it with a tungsten point, hit it with 0:13:19.655 --> 0:13:22.175 a tungsten scraper initially. 0:13:21.855 --> 0:13:25.535 Different the scraper is that different to your sutordinate scraper 0:13:25.535 --> 0:13:27.735 and buy it bunning then no, no, no. 0:13:27.655 --> 0:13:30.575 It probably is the same. I typically get I'm not 0:13:30.615 --> 0:13:33.415 sure who makes them, but they have an interchangeable blade, right, 0:13:33.415 --> 0:13:36.615 so you can replace the blades. So you can buy scrapers, 0:13:36.655 --> 0:13:39.175 but then unless you know how to sharpen them, they 0:13:39.215 --> 0:13:41.695 do get a bit dark. So that the tungsten ones 0:13:42.375 --> 0:13:45.775 are great because when the little tungsten blade, which is 0:13:45.815 --> 0:13:48.735 about an inch long about half an inch wide, when 0:13:48.735 --> 0:13:50.735 that dulls, you can flip it over, use the other side, 0:13:50.735 --> 0:13:53.135 and when it's really dull, throw it away, replace the blade. 0:13:53.575 --> 0:13:55.855 But typically if you you know, if you use that 0:13:55.895 --> 0:13:59.735 to scrape the surface and material comes off easily, well 0:13:59.775 --> 0:14:01.495 then you know you've got to carry on with the prep. 0:14:01.815 --> 0:14:04.055 If you scrape it and it seems to hold there 0:14:04.095 --> 0:14:06.215 and it's not terribly crazed and that sort of thing, 0:14:06.375 --> 0:14:09.015 you can send it, prep it and then top coat. 0:14:10.095 --> 0:14:12.375 But it's a good work fifty one years old, so 0:14:12.455 --> 0:14:15.015 I mean, yeah, but be solid. 0:14:14.815 --> 0:14:17.335 Oh yeah, absolutely. Look you might find a little bit 0:14:17.375 --> 0:14:18.975 of rot, you know, in a corner of a sill 0:14:19.095 --> 0:14:21.015 or something like that. But again, you can fetch that 0:14:21.095 --> 0:14:23.975 rot out and the windows will be good at least 0:14:23.975 --> 0:14:25.135 for another fifty years. 0:14:25.615 --> 0:14:28.135 So I should do that tongusten rather than just use 0:14:28.135 --> 0:14:31.095 a multi tool or something. We should just grind it away. 0:14:31.375 --> 0:14:34.095 Yeah, look you might. I mean it's a little bit 0:14:34.135 --> 0:14:36.375 harder on your hands using the tungsten, but you'll find 0:14:36.415 --> 0:14:39.495 actually that it takes off that loose material quite quickly. 0:14:40.375 --> 0:14:42.775 Okay, look, no, thank you so much. I'll let you 0:14:42.815 --> 0:14:43.055 know how. 0:14:43.815 --> 0:14:49.815 Please do you take care, take good care, Thank you, Tony. 0:14:49.975 --> 0:14:53.655 We'll talk to Philip in a moment. Quick text. My 0:14:53.735 --> 0:14:55.535 deck doesn't get a lot of sun. Do I need 0:14:55.575 --> 0:14:58.455 to stay? And that's a very good question for Jay 0:14:58.535 --> 0:15:01.415 Sharple's from Razine. He'll be with us just over an 0:15:01.455 --> 0:15:04.015 hour's time. Right, the lines are open. Now's the time 0:15:04.055 --> 0:15:06.135 to call. It is twenty one minutes after six with 0:15:06.535 --> 0:15:07.735 with Philip in just a moment. 0:15:07.895 --> 0:15:10.815 Whether you're painting the ceiling, fixing with fans, or wondering 0:15:10.815 --> 0:15:12.895 how to fix that hole in the wall. Give Peter 0:15:13.015 --> 0:15:17.575 wolf Cap call on eight the Resident builder on news 0:15:17.615 --> 0:15:18.135 dog zeb. 0:15:18.775 --> 0:15:20.855 I'm hoping I've got to this just in time. So 0:15:21.215 --> 0:15:24.375 last week Debbie sent me an email at around this 0:15:24.455 --> 0:15:26.375 time and mentioned the fact that she was heading off 0:15:26.415 --> 0:15:30.295 to work and asked a quick question about bathroom extraction 0:15:30.455 --> 0:15:33.855 and one hundred year old wooden house. Well, as it happens, 0:15:34.495 --> 0:15:36.535 that was exactly what I did. I get it finished 0:15:36.615 --> 0:15:39.975 last week. Yeah, I pretty much did until I got 0:15:39.975 --> 0:15:42.415 to the exterior grill. So this is a little project 0:15:42.495 --> 0:15:44.775 that's been on my list as well. So I've replaced 0:15:44.815 --> 0:15:48.735 the fan, I've run new one hundred and fifty miliducting 0:15:48.975 --> 0:15:53.695 along the ceiling and then where you duck out. Often 0:15:53.775 --> 0:15:56.655 this is a real challenge for all sorts of extraction. 0:15:57.215 --> 0:15:59.455 Is typically you know there's there's lots of space in 0:15:59.495 --> 0:16:02.095 the ceiling, but then when you get to the exterior, 0:16:02.975 --> 0:16:06.455 whether you're dropping over the top plate and in to 0:16:06.495 --> 0:16:09.055 a safite or in my case, the safite is pretty 0:16:09.095 --> 0:16:11.935 much level with the top plate, and so you've got 0:16:11.935 --> 0:16:14.695 to you've got one hundred and fifty milimeter round, but 0:16:14.775 --> 0:16:17.575 then suddenly you've only got one hundred millimeters height to 0:16:17.655 --> 0:16:21.575 transfer through. The temptation is to take that flexible ducting 0:16:21.615 --> 0:16:23.535 and kind of just squish it down a little bit 0:16:24.415 --> 0:16:26.775 and then poke it out through the safit. But that's 0:16:26.815 --> 0:16:30.655 not great. It tends to impede the flow, and so 0:16:30.815 --> 0:16:34.935 all of the recommendations from the ventilation extraction experts is 0:16:34.975 --> 0:16:37.335 you need to keep the same volume of ducting. So 0:16:37.415 --> 0:16:42.695 I transferred from a one to fifty round to two 0:16:42.775 --> 0:16:47.295 one hundred and twenty by ninety rectangular section, so round 0:16:47.335 --> 0:16:50.935 to rectangular, then had an elbow, so a ninety degree bend, 0:16:51.135 --> 0:16:53.215 and then I could drop out through my safit. What 0:16:53.255 --> 0:16:57.135 I couldn't find, as it happens, was a grill that 0:16:57.215 --> 0:17:01.015 fitted there. So in a moment of inspiration, just quickly 0:17:01.535 --> 0:17:04.855 as I was standing at my local resource recovery center 0:17:05.455 --> 0:17:08.855 we don't call them to anymore resource recovery center, about 0:17:08.935 --> 0:17:11.775 to throw the old one into the skip or actually 0:17:11.815 --> 0:17:14.175 the metal part was going to go for recycling. The 0:17:14.215 --> 0:17:17.015 plastic could also be cycled. I looked at the old 0:17:17.055 --> 0:17:20.055 grill and thought, hmm, I could make a new grill 0:17:20.295 --> 0:17:22.655 out of the old grill. So that's how I finished 0:17:22.655 --> 0:17:27.055 the safit detail anyway, Debbi, So that's hopefully an idea 0:17:27.055 --> 0:17:29.335 for you as well. So if you're doing the bathroom, 0:17:29.415 --> 0:17:32.295 what you want. The key to extraction is putting the 0:17:32.295 --> 0:17:37.655 extractor in the right place in the bathroom which often 0:17:37.775 --> 0:17:42.615 is not actually immediately above the shower, which is the 0:17:42.655 --> 0:17:44.655 mistake that I made some years ago, but anyway, I 0:17:44.695 --> 0:17:47.255 can't fix that right now. The other thing is to 0:17:47.255 --> 0:17:49.735 make sure that you're a ducting runs as level as 0:17:49.775 --> 0:17:53.375 possible and as straight as possible and as short a 0:17:53.455 --> 0:17:56.735 route as possible to the exterior, that you size the 0:17:56.815 --> 0:18:01.015 fan correctly, and ideally if you've got a fan, you're 0:18:01.055 --> 0:18:02.615 either going to have one that has a run on 0:18:02.735 --> 0:18:05.255 timer so that when you finished in the bathroom and 0:18:05.295 --> 0:18:08.215 you turn the hour off to the fan, it actually 0:18:08.295 --> 0:18:11.615 runs for another five minutes or so, because typically we're 0:18:11.615 --> 0:18:14.695 in the bathroom, we create lots of steam, and then 0:18:14.735 --> 0:18:17.055 we finish in the bathroom, turn everything off and go, 0:18:17.375 --> 0:18:19.455 but there's still quite a lot of steam in that space, 0:18:19.895 --> 0:18:22.655 so that's a key to it. The other key is 0:18:22.695 --> 0:18:24.695 that you don't crush the ducting as it goes to 0:18:24.735 --> 0:18:29.055 the exterior. That's really important as well, and increasingly now 0:18:29.575 --> 0:18:31.975 and I've got one of these to install another projects 0:18:32.055 --> 0:18:37.455 Simmis so Simx have developed a range of extractor fans 0:18:37.535 --> 0:18:40.735 for wet areas that have a humidity sensor in them 0:18:40.775 --> 0:18:43.855 as well, so they run constantly at a very low flow, 0:18:43.855 --> 0:18:47.175 which is great for ventilation and extraction inside your house, 0:18:47.895 --> 0:18:51.135 and then they ramp up when it senses that, hey, 0:18:51.135 --> 0:18:53.815 someone's using the shower. Basically we've got lots of humidity here. 0:18:53.895 --> 0:18:58.735 It ramps up and then reduces its rate, but constantly runs, 0:18:58.775 --> 0:19:01.575 and that's really really good. The other key factor for 0:19:01.615 --> 0:19:04.055 good extraction in a bathroom is making sure that air 0:19:04.135 --> 0:19:08.455 can get into the bathroom. So underneath the door, I 0:19:08.535 --> 0:19:11.215 think the recommendation is as much as a twenty mil gap, 0:19:11.575 --> 0:19:14.055 but even if it was, let's say fifteen mil, that's good. 0:19:14.135 --> 0:19:16.895 You know, when you trim doors off often you're going, 0:19:16.975 --> 0:19:19.215 I'm going to make that gap as little as possible, 0:19:19.655 --> 0:19:22.255 because that's really professional. But in a bathroom, you actually 0:19:22.255 --> 0:19:25.295 want that gap to be a reasonable amount so that 0:19:25.335 --> 0:19:28.215 you've got air coming into the room as you're trying 0:19:28.215 --> 0:19:30.895 to suck it out. Otherwise you're just creating a vacuum 0:19:30.895 --> 0:19:33.935 and that doesn't work particularly well for extraction. Hopefully that's 0:19:33.975 --> 0:19:38.135 some ideas. Debian. Good luck with your renovation. Hello Philip. 0:19:39.775 --> 0:19:45.615 Today, my question there is a product in insolmax insulation. 0:19:47.135 --> 0:19:49.575 Is their right to use in your opinion. 0:19:50.575 --> 0:19:55.775 So in saying this, you're being very specific about the 0:19:55.775 --> 0:19:58.855 product and the supplier. Because there are a number of 0:19:58.935 --> 0:20:04.975 blowing insulation systems, right, So some of them are foam, 0:20:05.055 --> 0:20:10.815 some of them are fibers, some are injected. Yeah, they're 0:20:10.855 --> 0:20:15.375 all essentially injected systems. What's your situation? Where are you 0:20:15.415 --> 0:20:16.215 looking to use it? 0:20:19.015 --> 0:20:23.455 Got a weather board house, yep, built in the fifties, 0:20:23.695 --> 0:20:28.015 iron roof, bats under the floor, beats in the ceiling, 0:20:28.335 --> 0:20:32.095 but nothing in the walls. Double glazing windows all around, 0:20:33.255 --> 0:20:36.295 and yeah, it's. 0:20:37.095 --> 0:20:39.655 The walls are now You're kind of your one week spot, 0:20:39.655 --> 0:20:42.615 aren't they. If you've gone to the extent of insulating 0:20:42.615 --> 0:20:45.215 the ceiling, you've got some insulation under floor, you've gone 0:20:45.215 --> 0:20:48.575 to the double glazing, which is great. Then the heat. 0:20:49.855 --> 0:20:52.415 One of the interesting things I learned just a couple 0:20:52.415 --> 0:20:54.975 of months ago, and I suppose I'd always sort of 0:20:55.015 --> 0:20:57.415 thought this, but I'd never had it written down in 0:20:57.415 --> 0:21:02.135 front of me, is that heat transfer is unstoppable. Right. 0:21:02.255 --> 0:21:07.015 The process of heat essentially trying to level out of 0:21:07.055 --> 0:21:10.775 its cold inside and warm inside. The world wants to equalize, 0:21:11.535 --> 0:21:16.015 and so heat will transfer through any particular barrier that 0:21:16.055 --> 0:21:19.295 we can imagine it will all so, but what we're 0:21:19.295 --> 0:21:21.655 trying to do is slow it down. Right, So at 0:21:21.695 --> 0:21:24.175 the moment you've blocked off all of these passages for 0:21:24.335 --> 0:21:28.895 heat transfer, but your walls, if they are essentially plasterboard, 0:21:28.975 --> 0:21:32.935 timber framing and some weather boards on the outside, heat 0:21:32.975 --> 0:21:35.775 will escape through there and through gaps and cracks and 0:21:35.815 --> 0:21:41.055 so on. I think I'll be really, really honest, I 0:21:41.095 --> 0:21:45.735 have often been skeptical of the blowing or injected insulation 0:21:46.135 --> 0:21:51.815 systems for walls. My own experience some years ago was 0:21:51.895 --> 0:21:55.015 working on an older house where I had to remove 0:21:55.095 --> 0:21:58.615 exterior cladding. We were doing some alterations and I could 0:21:58.655 --> 0:22:01.735 see some of the injected systems that have been injected, 0:22:02.055 --> 0:22:04.735 and you could see how moisture had affected it. There 0:22:04.815 --> 0:22:06.695
