I have forwarded the UFH stapler to @Great_scot_selfbuild

I can recommend the lamb on heating grid @torre mentions it also acts as the slip membrane between insulation and screed. I also have the build hub UFH stapler if you want to borrow it. The stapler is passed member to member, I would pay for postage to you and you keep for the next user and post to them.

I’m glad it’s useful, you do need to remember we are a bungalow, we found the roof insulation and floor insulation to be obviously much more than a house with another floor but we did particularly want/need a bungalow. ICF is fairly expensive but again that was our choice. it’s also amazing how costs have increased in such a short time, we are just about to order our front door and the original quote from Norrsken is now more than double so we are looking elsewhere.

The two consumer units may be because in 1995 we were installing the radio time signal for Economy 7 (in the country as opposed to towns) and storage heaters etc were often put on the second CU.

@DevonMade we put the ducts through the roof when tiling the roof.

Hi @DevonMade We’re having a Willis water immersion system for the UFH you can research that on the forum and a conventional vented hot water cylinder heated on economy 7 or solar diversion. We can install both ourselves so no labour costs, parts can be replaced quickly and cheaply if required. The cylinder has a shower coil and a shower take off to keep our options open. It’s mostly going to be just 2 adults. We have found living here it’s a lot harder to find tradesmen (plumbers particularly) than back in Manchester. If you need one there is a wait so you can be without heat/DHW etc, if it’s summer the holiday let’s seem to get priority. The above answer I would understand not to be as the norm. MVHR we have chosen the Zehender Q350 with pre heater (frost protection) buying online and installing ourselves. This is one of the few things that has come down in price in the last 3 years since research started. I was going for a vent axia but have read on here about bearings being changed after a few years (5 years?) and the price change has pushed me to the Zehender it’s better spec and quieter. Good luck with your own build.

Weeks 56 to 74 The UFH is laid and the screed is providing a lovely wobble free surface for the ladders and makes brushing up so much nicer. Our neighbour kindly lent us his scaffold tower so that we could insulate the vaulted ceiling in the open plan area which is approx 5m high. This has enabled me to finish insulating between the rafters with 140mm of Rockwool and I have PIR sheets to put up under the rafters. For cutting both the Rockwool and the PIR I created a few templates of different angles and had them ready for when my husband came to help pass them up to me. Once the Rockwool was finished we both took it in turns on the scaffold tower fitting the PIR. Having a vaulted ceiling in the openplan area and partially vaulted elsewhere will give us plenty of light and nice high ceilings but for now they are awkward to cut around to insulate and ensure the VCL is tight around the junctions. The time spent doing this will no doubt be forgotten once we move in and it is starting to feel closer. We marked out the kitchen island location and dining room table location to get first fix electic lighting located and measured for the kitchen units. For my birthday treat our daughter came to stay and dog sit our elderly Greyhound so that we could go shopping looking at kitchens. We spent almost 4 hours in Wren Exeter with Harvinder but we think we have ordered a lovely kitchen and pantry. Unfortunately our neighbour needed the scaffold tower back but said we could borrow it again as soon as he had finished with it. We then decided we should book in the plasterer as things were starting to come together, rather luckily for us our plasterer had just had a job cancel on him and when we spoke to him on a Thursday he said he could start next week either Tuesday or Wednesday. As we hadn’t finished insulating one side of the vaulted ceiling we said we couldn’t be ready that quick unless he wanted to quote for fitting the PIR and the VCL, which I had already purchased most of. We then spent the weekend and Monday getting first fix electrics in the kitchen and mocking up where the TV was going to get the electrics and room wall lighting ready. Things have therefore started to move on quicker than we expected, so we are hopeful of moving in by winter this year with a working kitchen, one bathroom and one bedroom finished at least. Kitchen design render. Testing TV and speaker location. Even with the plasterboard lifter its hard with 3 on the scaff and one on the lifter, so glad I'm not doing it. Taking time off the insulation has meant I can tidy the UFH expansion foam up in all the rooms and the trip hazards we kept ignoring at door room openings, whilst being on hand for the plasterers if they need more tape etc or have any questions. Once they have finished with the VCL membrane I might finish the VCL I started before we borrowed the scaffold tower or I could take a rest from the build and catch up on so many other things, even paint schemes maybe. I have caught up on the build paperwork this weekend. The total spend to date including the provisional kitchen figure of £15,000 which includes VAT, units, worktop, tiles and some appliances so not the reclaim amount. Total to date £238917 over 135m2 is £1770 m2 for a 3 bed, 2 bath, bungalow This is broken down as follows. General £4200 Carpentry £500 Kitchen £15100 Roof insulation, inc membrane and tapes etc £4500 First Fix Electrical £1230 First fix plumbing and partial bathroom costs (ongoing) £1430 UFH £900 Drainage and gutering £8540 Floor insulation inc tape and membranes £2670 Screed £2740 Cladding (over ordered but ideas are developing) £5690 Render £3090 Solar 7.5 KWp £8570 Roof £23300 Windows £20870 no front door yet. ICF Construction £119600 Pre build costs and fees etc £15830 The back of envelope guesstimate of future spend is £35k to finish apx £2k per m2

I taped mine up the walls and the studs. two layers of insulation with staggered overlaps then a thin slip sheet before the UFH. the slip sheet is also taped up the walls my dpm is taped up more so the slip sheet is also taped to this. can you get any insulation in the studs below screed level? Easier to put in first and gives something to tape onto. Then maybe some noggins for the plasterboard later. I presume you’re having UFH, all the layers you tape up the walls and studs should be neat and tight. This gives something for the expansion foam something to stick to in the studs where there would otherwise be nothing.

Still ongoing. Hope to put my last insulation order in soon. The points you get can be used across all the group sites but I haven’t purchased much more on the other sites.

I have been buying my insulation from https://www.insulationsuperstore.co.uk/ I have had multiple deliveries from them, at least 10. I have purchased rock wool and PIR only once did the delivery come on a huge truck most came on a small van and the drivers were very friendly, delivered from SIG or Markovich, with good delivery communication. The Rockwool I purchased by the pallet, the PIR by the sheet mixing my order 80mm and 100mm and spending the minimum for free delivery which meant I was not stacking rooms full and risking damaging corners. I was often getting discount codes or used my account points to get money off never paid the full price.

Things are all progressing well. You will be living in a nice warm house with a good shower well before me.

Glad you got it sorted @SelfBuildSmurf . I have the build hub UFH stapler ready to pass on to who needs it.

I have recently used both types of expansion foam with and without the skirt. I found the skirt, often yellow foam, only had one small strip of adhesive on it to stick to the walls and wasn’t a snug fit. I also had one without the skirt, blue, which had a full depth of adhesive on the rear that stuck really well to the walls and studs.

Welcome to the forum. There are quite a few of us building our home for later years. you sound like you have a lot of building experience to pass on.

Norrsken measured my openings and we discussed our XPS ICF and it’s load bearing. The ICF company were happy with its capabilities but it was Norrsken who were more concerned about the installation whilst in progress. I’m not sure of the compressive strength of your ICF but it was where the packers go and point load whilst in the installation process. It is possible to push your thumb in our ICF and make a small indentation and as it’s not memory foam that small indent will stay there under the frame. Similarly the packers could push down in to ICF. Norrsken provided stokbord to sit the frames on. I EPDM before the stokbord and then taped the windows after. Were fairly coastal with high wind and rain and open to the countryside with no buildings buffering us. Windows have now been in a year I think and we’re not plastered so can still see the Icf and no water leaking in around windows.
