So when Scotland devolve and we have to build a wall adjacent to the A74, who's rules are we going to follow? Or should we keep it simple and make it a hedge?

Dear god the Welshman has actually been listening to what we have been saying ..!! @Nickfromwales is after an admins job ..!

Dee, all you had to do was check a few phone boxes and you've have found our sordid website. Good to hear from you . He decided that this was a path he'd rather not tread I'm afraid. I believe you can find him on the GBF . I do miss the grumpy old git

@ryder72 Will your WC's be as I've pictured, eg, part height with a shelf top, or will your framework be floor to ceiling ? Do any cables or other services already reside in the counter batten spaces in the bathrooms ? I need those questions answered tbh so I can advise further, without going off down the wrong route, but at the moment I'd be looking at removing the 70mm PIR and removing all the 38mm counterbattens, and then over boarding the whole wall with 25mm ply, screwed through to the 140mm frame with 120mm self cutting heavy duty wood screws, repeated at 200mm centres. Then fix the frames directly to the plywood. ( The point that takes all the stress is the top fixings of the frame which go back to the wall, and there's a lot of 'pull' on those. If those dont get fixed properly then the frame will move and the plasterboard and tiles will move with it ). After the frames are fixed, refit the 70mm PIR over the plywood, around the WC frame, and you'll then gain around 83mm of floor space back to the room too. Is that an option?

This is how I did them . Have a look, and I'll add some details tomorrow.

Geez I've missed ebuild... And just in the nick of time you're back !!! Prepare thee for many many posts on dormer window construction.... Joiner, Temp..... HELP!

Anyone looking for Kingspan..?? Had 32 of these delivered today and they are pretty much perfect ....! 125mm PIR for £25 a board (inc delivery) is a fantastic price as the closest I could get was £33 https://www.secondsandco.co.uk/product-page/123-128mm-1-2x2-4m-foil-foil-boards

No refunds given ✌️️ Last time I 'sabotage edit' one of Peter's posts ? "If you can't do the time, don't do the crime"

Make your own manifold - what a great idea Joe, you could make an MDF box and cut THESE in half and glue them into suitable holes to make the flexible duct connections. Spend some time saving money and you get exact the number of outlets you need.

Oh, and sorry @Dee. Another innocent thread hijacked and disgraced. Freedom of speech isn't all it cracked up to be

Penis, I mean truce.

Yep I think you need to check yours too ....

Hi @Dee so... if you put an @ before someone's name it notifies them they have been tagged if you choose to click notify it will send you mails hope that helps ..?

The door is open, he's has only to walk through. There are a few 'missing in action', a bit like yourself, but hopefully as time passes the repeat offenders will surface .

Oh you have no idea what a relief it is that your all back! Just as I'm about to start the final piece of this project, a hip dormer this weekend... ? timing couldn't be better

Ian, your not the antichrist. Don't be so harsh on yourself eh? . PS ✌️️

Hi Dee, glad you found us OK.

Revieved all the parts so will attempt this tomo. Thought you would like to see the results of checking the magnaclean filter Not been done in a while!

No problem! I tend to keep details vague online..... Pure fluke I found you... ?

Hi Dee and welcome (back) We did try and contact as many of the old regulars as we could find contact details for and sorry you slipped through that net, but now you are here please carry on as before.

And the Antichrist is here too! What more could a builder want for?

Let it all wash over you until someone threatens a course of action which will hit you right in the bank balance. This has little to do with the fence or law. Be warned by the lack of polite initial contact "How's the fence-building going then?" followed by a light hearted discussion. Some other agenda is playing itself out, and likely as not, you'll never know. Wait, force delay, prevaricate, forget, refuse signed-for mail, look the other way, until your bank balance is attacked. Unpleasant, yes. But low-energy. Low worry. If, on the other hand, the complainant asks to chat, engage, smile, reassure. Agree.

Sad to hear this, but not surprising, given the massive cliff that has to be climbed to get a reliable product like this to market at a reasonable price. Pretty much all the existing battery core technologies have been around a long time now, yet very few seem to be able to get beyond the engineering prototype stage and into large scale production. It's taken lithium ion chemistry cells around 26 years to get from initial production to large scale adoption, and even now development is still improving ion exchange cell chemistry and construction, so I think it's probably reasonable to say there's likely to be around a 10 to 20 year period from first commercial production to a large scale reliable battery system being available. The big hurdle for any off-grid storage system is going to be the cost of storing energy. Current lithium-based ion transfer energy storage solutions seem to all be limited to at most a 15 year service life before cells degrade to the point where they lose too much capacity to be really useful. So if weight and size isn't an issue (and, unlike vehicles, it probably isn't a concern for domestic off-grid systems) then it probably makes more sense to go with cheaper and well-proven cell chemistries, as they are likely to have a lower whole-life cost. The really big problem with this is that the big demand for batteries is electric vehicles, so that's where the development funding is going, and electric vehicle batteries have a completely different set of key requirements, with being small and light being close to the top of the list. The only country that seems to be looking at off-grid energy storage pragmatically seems to be China, as far as I can see. They have a pressing need to generate more electricity and yet reduce pollution levels, so are spending very large sums of money on alternative energy generation and storage. Interestingly, they seem to have been developing a mix of two battery types, longer life lithium ion cells, plus they're manufacturing ancient NiFe cells again: http://www.changhongbatteries.com/ .

I've done Crossfit on and off over the last few years, but recently decided to take a break for a few months to focus on strength training. I was never any good, but my wife's massively gotten into it since taking it up late in 2015 (to the point where she's just qualified for this : http://www.europeanmastersthrowdown.com/) Anyway, interesting stuff. Will let the thread get back on topic.

I've been in @PeterStarck's place and it is without doubt the warmest, quietest, most draught free house I've ever been in. Sure a lot had to do with the spray foam getting into places rigid PIR just wouldn't. (To be fair it's the ONLY Passivhaus place I've been in).

Do you do Crossfit?

It all depends on the installer, for me the cutting back was a major part of the job. IIRC we ended up with around 70 large bags of offcuts which we had to take to the tip. It's a great material though and very airtight.

Useful info and update on the last 8 replies. Like the plastic tube idea and I suppose having taped felt would aid the issue of the foam coming out between the overlaps but is a lot of effort to prevent it. Do they cut it back in preparation for the OSB or do you and who disposes of all the offcut waste? In short would you recommend it?

Let's answer the op then. If the 38mm battens are through fixed at regular intervals where the WC fixings reside, then I see no issue, but it is a lot to ask at such small points TBH. Adding a horizontal wall plate, as I've done with 7" timber in my pics, would straddle 3-4 of the 140mm frame studs and give you some serious rigidity. Show your plumber the pics and see if he is OK to cut sections of the counter battens out and fit a similar plate arrangement. For belt and braces I then fitted the 40x40mm UniStrut and punched timber locks through the UniStrut, wall plate, air tightness OSB layer and into the frame studs. To demonstrate how good these fixings were, I stood on the front edge of the extra long projecting WC pans, after mounting them to the frames temporarily through a disposable plywood baffle ( to represent the PB and tile layer ) and bounced up and down on them. You could park a car on them ( 3 X WC's on that same elavation ).

If you (we) are prepared to put the time in (reading like a demented bookworm) then it's almost all here. Wot I need now is a personal master switch that enables OFF to be selected for an hour or so in the evenings and every other weekend. Does ECObuild sell those?

When was the last time you were hit with a medicine ball or two? 2 mill metal.

Just a thought but have you considered the issue of sound proofing beteeen the two units? It might not be an issue for you. When we did the same thing at our unit we ended up with a simple stud wall, filled with rockwool and skinned with OSB, It worked out cheaper than anything else.

Google says 8kwh of heat for 1 kg of coal. As a side note uranium-235 is way better at 24,000,000 per kg. Get a block of it and put it in the stove and your sorted!!!
