Sticking Aerogel to steel
Great_scot_selfbuild replied to Great_scot_selfbuild's topic in General Construction Issues
Here are two companies I’ve spoken to: https://coreprosystems.co.uk/thermal-insulation/ https://www.thermablok.co.uk/our-products/ I’ve sent them details of what I need and am waiting to see what comes back. A lot of valuable detail came out I. The call that I hadn’t found on any website. The description ’flexible’ is a bit misleading g as the bare material (not fitted to another type of board) doesn’t actually sound very flexible at all! 🤞🏻🤞🏻🤞🏻 - Yesterday

Not sure who that’s for, but, you know me……. The main isolator in the CU is a switch, and after that each 1ph or 3ph circuit is protected individually. Caveat with 3ph is, you need a 3ph MCB to give you the over current protection, and then a higher amp rated 3ph RCD locally to give the earth protection; 3ph RCBO’s don’t seem to be leaping into my lap? Anyone? @Mattg4321? @ProDave? @Onoff?

Preparing to Screed - What to consider....
Nickfromwales replied to Mulberry View's topic in General Construction Issues
I chatted this through with one previous client in Gravenhill, as they only allow a B&B floor there. We decided it best to buy a few (very) large tubs of black jack (liquid DPM) and use that to make the B&B airtight too; this was brushed up the upstands too. Here’s a pic of it, please ignore it being wrecked temporarily to install the WC pipe where it actually needed to be, lol. Back in the trenches again This was done vs a sheet DPM, and imho this is night & day better. Zero tape / dodgy internal and external corners to fold. 👍👍👌 Oh, and yes, I did have to suspend that WC frame in place, FFL calculated and datums a plenty, stud wall created virtually in mid air, before the polished concrete went down……. I had about 4mm of tolerance to play with. All was A1 of course as OCD wins every time lol. -

Nickfromwales replied to Mulberry View's topic in General Construction Issues
Nope. And there isn’t a ‘wrong way’ here btw . Most UG pipe is sold ‘socket-less’ meaning it is just straight pipe (plain ended as you call it) which is directionless and completely normal. FYI a ‘socket’ is what the plain pipe goes into for each joint, so you get single or double ‘socket’ bends, one male and one female end, or both ends female. We’ll learn you good, boy!! -

I just use a few ‘turns’ of squirty foam to give said wiggle room, but as above, more importantly, gives you the option to slide a fitting (with its knuckle) after removing some of the foam. I am in the process of fine tuning the 1st fix for the GF cloak WC that this particular pipe services. There’s a full 20mm of ‘wiggle’ there, allowing me to get the fully-back-to-wall close coupled WC in to perfection. Cost, £5. -
Where are all the Blown Cellulose Installers?
Nickfromwales replied to SBMS's topic in Heat Insulation
Massive lump of a thing tbh. Gordon Lewis operates off a 13a plug out of the back of his van, small hopper and tired / busy old fella constantly tossing bales into it, and the man is like a dog with a bone; literally fills every last nook and cranny until the pump wont push the Warmcell down the pipe anymore. If anyone wants Warmcell blowing in, he’s a legend. And Welsh. That’s a win-win lol. -

Imagine being the persons sent down there to install those props?!?!?! They’d have had the 2-finger salute from me. Feck that. -

@DamonHD had a similar product fitted a few years back. It is worth noting that insulation is an inverse square law by thickness. If say 5mm reduces the losses by x, doubling the thickness to 10mm will reduce the total losses by x + x/2. 3 times the thickness, x + x/2 + x/8, and so forth. -
Nothing whatsoever wrong, if they fit in the space you have. We had to preserve space here for the mist system box-o-tricks, 19” rack for LAN, 3ph CU, (and more), in that one plant room, ergo I had to get inventive and make space. The original design had the 24 port Ubbink manifold boxes specified, but it meant encroaching into the adjacent coats / boots room which wasn’t going to fly. Happy to use them where you can though! And you can get bespoke box manifolds made up to fit in the posi joists too: I offer up the bare boxes, mark the metal webs onto the side of the box with a sharpie, then drill and fit the top hats to take the 92mm ducting. IMO there’s a lot of real estate up there so why not utilise it vs lose GIA / have to make boxing in etc?

How do ecology BS value each stage of the build
PSC88 replied to PSC88's topic in Self Build Mortgages
My plot was valued just under £800k. i was released circa £510k which was my max draw down of 65% I used this to clear my previous resi mortgage and pay for warranty and initial site enabling and Groundworks. i will be at block and beam (at a push first lift) when I request the second draw down. my end value has been conservatively placed at just over £2mill and my initial valuation report stated wind and water tight would value at 1.5mill Im restricted to max 65% draw down. my ideal scenario would be by end of 1st lift they value at £1.2 mill this should carry me to shell stage with roof covering complete and then just windows and doors to fund myself. -

Is there an inexpensive MVHR diy option?
LnP replied to Wadrian's topic in Mechanical Ventilation with Heat Recovery (MVHR)
Congratulations on your metal bashing skills. Is it a normal part of an install to have to fabricate distribution boxes? What is it about the off the shelf ones which makes them not suitable, like these Ubbink ones? -

Nickfromwales replied to Great_scot_selfbuild's topic in General Construction Issues
By the time its squashed or has fallen half apart, during cutting and installation, I'd beg to see anything that offered much of the assumed uplift there tbh. Any small thermal separation will offer huge dividends here, but hey-ho! -

I agree kudos to the people involved in all the props going into the building. I don't think I would want to be in there, but I guess the risk of injury/death from collapsing is huge as surrounding buildings could go as well. -

Serious kudos (props? 😂) to the person that put the first acrow in there. And the other nine as well. -
erm just tried ultracode to find a nasty bug.... 70k tokkens gone in 20 seconds! 7 agents on the job. Dont really get how this agent thing works but I;ll let it run and eat my 5hr limit in 10 minutes LOL! 100k! sounds a lot! I always think of it as £'s! 400k!!!

Redbeard replied to Great_scot_selfbuild's topic in General Construction Issues
Have you got any links? I cannot find anything that is other than an aerogel/Spacetherm blanket stuck to a board - whether Magnesium Oxide or Plasterboard. I was loosely involved with the planning of a refurb in 2009/10. The contractors hated the pl'bd/aerogel laminate (a) for being so dusty and (b) as the mesh in which the aerogel was held 'picked up' when drilling for fixings, potentially hurting wrists or sending operatives spinning! -

I plan to do this internally, where I have the space available - I don’t have this option externally. -

The thermal property of tilebacker boards is nowhere near comparable with aerotherm though. -
Sticking Aerogel to steel
Great_scot_selfbuild replied to Great_scot_selfbuild's topic in General Construction Issues
Is this aerogel or spacetherm? From the suppliers I’ve approached, aerogel is like a stiff board/sheet (these pictures look like a loose fabric). It appears that the term ’aerogel’ is used across a variety of products, but not all with the same thermal value. -
I have 9 supply and 6 extract of 90mm Ubbink, which is what those pictured above seem to be. My MVHR unit is in the loft. To get from the loft to the ground floor ceiling i had a double stud wall designed into the Potton kit with a 100mm gap. This allowed me to hide the vertical drops neatly. Potton said ' oh thats a good idea'. Manipulating the ducts 90 degrees to get them into the Posi joists at the ground floor ceiling was the hardest bit. And remembering to lay them in the correct order such that they weren't needing to cross each other as they distributed away to the ground floor rooms. The trick is ,you need to try to get the twists out as you go because its a total bastard to think ' i'll sort that once its in'. Ask me how i know. Only other real issue was trying to remember and calculate what end pieces and joins you might need to clip it all together. Waiting for the little bits that you forgot to order is painful. I have to say the Ubbink ducting is brilliant. If you ever played with Lego as a kid you will appreciate the way it just works and clicks together 'just so'.

No, and I think it’s sold now. I see there are other machines on eBay though. -
