Celotex. Cut to fit inbetween the timbers. No too thick, so at least some of the timber vertical face is visible. That way, the timers can half a decent chance of staying dry, and not rotting away. Celotex needs to be a good fit. Gapotape is your friend. If expensive.

Ok, im back. Again After lots of thinking, researching, pricing up etc, i think ive concluded that my cheapest viable and worthwhile option is celotex or similar in the roof, rockwool slabs on the walls covered in steel cladding. Ill put the celotex in between the galvanised purlins, which means smaller pieces thus easier to fit, but will need careful detailing. This leaves airflow over. I intend to use 120mm which means that i can have 20mm covering the bottom of the purlins. The only issue i see with that otherwise clever plan is the steel joists (red oxide) will be inside the thermal envelope in the roof, but outside it on the verticals, where they are in the cavity. Realistically, thermal issues aside, does anyone see a problem with that?

Just to update this, ive concluded there too many issues with filling the cavity, and its only 75mm anyway. Im going to line the inside with rockwall slabs, prob 150mm and panel over with steel cladding. Accepting that i need to do it myself, its not working out more expewnsive than beads on the face of it. Though i will have to extend the wiring out to the relocated sockets, but thats a minor irritation.

Mine had a DPM too. Straight on the mud. Given what you have told us and posted pics of, id bet there no PIR or anything else to be seen. Just drill a hole through it and find out. 10 mins work and you will have the answer. Im going to do the same on my welsh house soon, just as soon as ive sorted out some more pressing issues. That too has a recentish floor with DPC. Again, i bet it doesnt have insulation. The infra red thermometer says floor temp is 8 degrees. If you have evidence of damp in the walls, you seriously need to reconsider using a DPM. I used foamed glass for this reason. If you have gypsum plaster, that needs to go too. It will stay wet forver otherwise. Though some are a bit hardcore, id take a look at the period property forum. Lots of experience there. Not to suggest there isnt here, but this is more focussed on newer stuff. Im a few miles east of Llandovery.

Easy to find yes. Try actually purchasing, which is the OP's issue. You cant.

Id guess theres almost certainly no insulation under it. Just like mine was. Do you not have any damp issues with the wall? Given the age and lack of a dpc, id expect them to be a bit damp., especially if its got a DPM under the concrete. Damp walls are cold walls. Though a lot of stone used in welsh houses is completely impervious to water. We broke ours out, used foamed glass as the sub base and insulation layer, so minimal excavation depth abd also to resolve the issue of moisture going sideways to the walls. Our walls are brick and like sponges. Damp doest start to cover it! And fitted underfloor heating while we were at it. transformed it. The walls remain uninsulated, but are completely dry now. Sits at 21.5 c all the time and a humidity of 55-60%. Obviously we got rid of all the sources of incoming air too. If you are going to do anything, do it properly, do it once. We did everything ourselves except the actual slab. But knowing the humidity will tell you a lot about whats going on. My guess is that it will be quite high. Prior to the work, ours was always over 90%. At that level its always going to feel cold. Having just bought a welsh stone cottage with a concrete floor, it looks like i get to do it all again

Is the floor currently concrete?

This is no weather to be working outside! -7 this morning. In buckinghamshire!

Slight thread diversion! Octopus seem to be saying you can ony have this tarrif to charge an EV? Im assuming that some of you are not doing that. How does that work?

Hmmm, will be interesting to see if that pans out. What sort of value properties are getting that much knocked off? Probably just a return to 2021 prices? Ive been following it closely for 5 years down there. Some grossly overpriced stuff this year.

But that different motar doesnt go round to the other wall. Indeed stops short. on the main wall. Putting my cynical hat on, forgot to install it, fitted injected DPC instead.

Still pondering this. Given the complications, ive been costing up insulating inside the inner wall with rockwall and steel cladding sheets. Got a good handle on the cost of that. The question is, whats the cost of installation EPS beads? (given its not really a DIY job) Does anyone have a recentish approx price per sqm?

Thread resurrection. Im looking for one too. Should never have sold my old one Anytime in the next few months if someones project is coming to an end. Circa 3 ton, but consider a bit either side of that. Circa £7k would be nice. looking around, there are no old diggers Where did they all go?

There does. They look like those pointless things they insert to "create" a DPC. That dont work. As you say, doesnt appear to be a DPC. Plus the motar below the holes is different (and more recent) that above it. Id suggest somethng has gone on. Need to find the DPC. Maybe they "forgot" to fit it. All that said, it will be wet, paving is up against the brickwork. Not a great idea.

Some carriers clearly have too much business!

If we wanted be be clever, we could cater for the higher vat rate and duty via the website. As it is, i like simple. So effectively, we take the 3% hit on the extra VAt and another 3.5% on the duty in the case of ireland. But we could have a function that as soon as you entered your country, it recalculated the cost to reflect that. The shipping is what it is. Thats not changed. We always charged higher shipping costs to ireland than the UK. Because it costs more. Pre leaving the EU, there were proposals to charge the destinations country VAT rate, in order to avoid those in high rate VAT countries purchasing from low rate ones. Dontr know how far that got, but it was inevitably coming. My point is, if you want to make it an easy transaction for the customer, you can. It only falls over on low value stuff, because DPD charge a smalll fee for managing the payment. Its a flat rate per shipment. Our irish customers see no extra cost post brexit than they did before. Im happy that some of our competitors dont want to do this. All the better for us. Edit to add, i didnt actually answer your question, what you "should" be paying, is £800 + shipping. Then on arrival, duty at the appropiate rate, and VAT on the cumalative total. Anyone charging you VAT on an export is either incomptent or a crook. Theres no complicated paper work. The invoice and the shipping details proving export is all you need to retain to keep HMRC happy that you didnt charge VAT. And your VAT return reflecting the correct numbers. But you have to do all of them anyway. Anyone trying to charge me their VAT on somthing they were "exporting" would be told where to go in short order.

All interesting stuff, but as you say, no reference to graphite coated beads. That seems to be the missing piece of info, as cleary, on a cost basis, its the winner.

Mineral wool is out as an option. Too much risk of wind driven rain. Closed cell foam would work, but bankruptcy would follow with that . Likewise with vermiculite. Any idea what the open cell foam was?

Exporting WITH vat wont reduce the paperwork. If you dont fill in the commodity codes, its going nowhere. If you do, then why are you charging the customer VAT? Its exactly the same process as sending something to any other country. We do it every day. Its not hard. For export into europe, we use the DPD duty paid service. We collect the full amount with VAT, ship, and DPD pay the duty and VAT on behalf of the customer and back bill to us. We use the 20% extra collected to pay it. Completely seamless for customer, just as it was before. If, as a business, you cant be arsed to do this, you clearly dont need the business. But dont say its hard or difficult, because its not. It only becomes difficult on very low value items.

Dave is correct. Why are you paying spanish VAT? Either, they are not VAT registered themselves, truly dumb, or taking the p and charging an extra 20 something % because they can.

Hmmm, thats definitely not me!

Ok, i follow the logic. But i still have the probem of insulating it. And every other option will be mad money.

Cut diagonally as per my pic. Raise the centre section then angle the side bits so no contact with render will take place Can be 100% from your pic, but it looks like the path is running uphill to the door alread?

Tranforms in what way though. Sorry if im being dense.

Err radian did, as did i. Up there ^^^ Its ALL in the cavity. Literally everything. Unless it the lighting on the roof. Rewiring on the scale involved isnt really an option. Building is 75 x 40 ft. Wiring, sockets etc, all the way round!
