    Yes, i mentioned that in my other thread about my house, which is why ive considered involving a BCO, where, normally i wouldnt. 2 years inside for fitting a window seems like overkill V the offence. How dare i. I should allow someone with a can of squirty foam, but sporting a fensa certificate to do a crap job instead. For my barn/shed call it what you will, trying to comply means costs approaching 100k. Its just a (big) workshop for my cars, toys and stuff. Not happening. I can of course make it much better for circa 20k, but that wouldnt be allowed. Even at £20k, its cheaper just to burn diesel. Id just prefer it stayed warmish at a more constant level, as it will be better for the stuff in there, and means it wont be freezing cold when i go in there in the morning. Takes a coule of hours for the blower to get it from zero to 12c.

    With a sustained cold period very! Same as outside pretty much Walls are block cavity, so that slows things down, but is just cement board roof. Ive got waste oil burner with blower that i now run on red diesel, but that makes for expensive warnth!

    In mine, with its completely uninsulated roof, its always noticeable warmer up near the roof. Pushing that air back down is almost free. Yes, OP seems to have disappeared? Shame as it looked interesting.
  4. Roger440
    Yes, sadly the whole building regs issue comes up. Given the proposed insulation by the OP, im guessing thats the requirements for a commercial building as it clearly is less than domestic. I wont comply as to do so would be prohibitively expensive. The roof for mine, just the roof, came in at circa £50k. Id have to live until im 300 years old to see any payback. As always, the requirements put you in an "all or nothing" situation.

    Circulation fans will be essential, and useful whatever else might be done.

    I had EPS up the side of the slab. It was steel framed with insulated steel composite panels. So the panels were screwed to the frame. The inner steel layer is inside the the envelop. The insulated parts sits on top of the EPS, and so the outer steel layer is outside. Yes, the securing screws are a thermal bridge, but thats inconsequential id suggest. So no thermal break in the envelope

    Hmmm, this is interesting. I too have a 3000sqft "warehouse" that is my workshop with some accomadation built in. The accomadation is insulated all round with 50mm PIR so not great, but OK. I want to keep the main area at 12c over winter. But without it costing a fortune. Ive spent ages going over all sorts of options, for insulation and heating, so far with no decision. The accomadation is currentl;y direct resistance heating which is bankruptcy inducing to use. All this talk of draughts is valid for your regular commercial building, but can be overcome with good attention to detail with the insulation. Its interesting that, almost universally in the UK, warehouses are unheated, with local radiant heat for operatives at packing stations etc. However, our owning company in Poland, their warehouses are all heated to 16c. Unsurprisingly, they are all heavily insulated. Pretty normal there. Ive also visted sevaral in germany, including a couple of huge ones. All heated. It can be done.

    When i built my insulated garage, nobody understands why, so i feel your pain. My answer is why would you build an uninsulated garage. If you are going to spend any time in it, or store anything remotely valuable in it, then it needs insulating. If you are not going to do any of those things, why builld it al all!
  9. Roger440
    This is excellent. I should have asked here about the foam glass insulation but already asked on your other thread.
  10. Roger440
    What ewas the reason for the foma glass? Ive used it , so am familiar with it, just not sure why in a new build garage? When i did mine, i created an insulated bucket of EPS to put the concrete in, so like yours an insulated slab.
  11. Roger440
    Having used seconds and co a couple of times, the stock i bought showed no discernable issues aside from the odd chipped corner. Id have no hestitation doing so for something like this. For both layers.
  12. Roger440
    Interesting approach (get it!!) I failed to come up with a solution on the garage i built at my first house, and so had that big thermal bridge. Was never happy with that.
  13. Roger440
    Or hardcore/stone (thickness dependant on ground) with sand blinding. 150mm PIR, 100mm concrete. Even less digging. Only negative if you can call it that is slower response time on heating. Worked fine for me in an old house with uninsulated walls. It just sat at a constant temp all winter. Without knowing the foundations situation less digging = better in my world.
  14. Roger440
    Agreed The work signed off in my case, was, afterall, done by the developer not the BCO But it was signed off by the enforcers of said regs. At best it was gross negligence, maybe corruption, but i cant prove that. I guess my biggest issue is that there is no comeback on the inspector. They cannot be held responsible for anything, unless you have extremely deep pockets.. Which is of course why we are where we are with the latest round of changes. And why i question the value of the process and the certificate. In my case it wasnt worth the value of the paper it was printed on. Anyway, this is largely a diversion
  15. Roger440
    Ok, heres some crude sketches of my plans as they stand at the moment. As you will see, the back of the house is cavity wall, not solid. Ive not worried about this too much at moment as this is a bit more conventional, though still going round in circles re EPS beards. The insulation system referred to is: https://woodfibre.co.uk/internal-wall-insulation-iwi-28-w.asp Hopefully its mostly self explanatory? Any comments welcome.
  16. Roger440
    I think you may have taken that out of context a touch. If im going to do something that either complies, or in this case is otherwise acceptable, then it is fact that it adds cost. It doesnt add anything beyond this. The overall outcome isnt "better" in any way because they are involved. Their additional cost in isolation isnt that big, but the costs of generating drawings, SAP assesments and whatever else they ask for all start to stack up quickly as these are things i cannot do myself. All to do something that is a well recognised solution to insulating an old stone building. I would however take issue with the assertion they keep standards high. From my limited experience, its been anything but as i have previously posted. The latest round of changes to the system reflect the fact it wasnt working and standard were not high, ie, like my old place, where they were happy to sign off any old crap. Indeed, stuff that wasnt actually there. Im not in any postion to have big arguments with them as its not my specialist field of knowledge, so am really keen not to find myself in that situation. Nor can i "add budget" to the job, as indeed you might as a professional in the field. Off to do some sketches.
  17. Roger440
    i will do some sketches and post them. They will be just that though, sketches. You are a professional and in the trade. A BCO is rather more likely to take notice of you, than a DIYer like me. My, limited, experience of BCO's hast been a good one. Hence i now, in the recent past, simply havent bothered. Its adds nothing except cost to the end result. And I wasnt concerned as there was virtually no risk of any enforcement action. Thats seems to have changed. One question before i go and do some drawings, your discussions with the BCO, do they still do that? Under the new regulations, my understanding is they can no longer offer advice and suggestions? (or at least are not supposed to).

    Currently, it's cheaper to buy oil than to to do the work. Based solely on the financials, no rational person would do anything. However I do prefer the increased comfort from said insulation. Yes, you are correct that the BBA certification should be ok, but often isn't with some of the less mainstream stuff. Essentially though, if I understand correctly, I will need to pay for drawings plans of my proposed works, bearing mind until I strip everything, I don't know for sure what's there, in order to pay for an sap assessment. Just guessing, but what, £2-3k in reports before I've done any work? Assuming it all goes to plan and there's no surprises that require the reports to be reworked to reflect reality.
  19. Roger440
    I may not have explained myself well. I'm sure the report will be fine for the proposed works. My concern, given the construction method of the house, is I will need to use something like wood fibre and lime plaster, for example, which, clearly, many BCO's dont understand and/or are unwilling to sign off. Under this scenario you then have to go round the loop again with an alternative proposal . Repeat until agreement is reached. What the going rate for such an assessment for a whole house project? I've never done such a thing. I assume I'm going to need to provide a detailed plan/drawings for them to work from too? So another person to pay.
  20. Roger440
    Thanks. So now I have to pay someone (someone suitably qualified) to write a report on the payback. Potentially more than once if the BCO doesn't like my solution. How do you guys work with this nonsense. Or more accurately budget for anything. It's essentially open ended expenditure.
  21. Roger440
    I really don't understand how you arrive at the conclusion reading the document. On another forum I use, the couple of BCO on there have a very different interpretation from yours. Their view is, 10 year enforcement applies to everything covered by building regs. Accept of course, that until some of this stuff happens in real life and gets tested in court, we can't really know. But the document specifically refers to ALL notifiable work, but with more stringent regs around high rise buildings.
  22. Roger440
    It's still not straight forward though is it? As has happened many times, the BCO wants a "modern" solution, probably because it's what they understand, even where that is incompatible with the building, as, in this case, stone with no dpc. In this scenario, the BCO has all the power. Even if they are wrong. This is the situation I'm seeking to avoid more than anything else. I can't say no, thats nonsense I want to do this instead. Well I can, but they are not under any obligation to accept it. I want aware of the 15 year payback. Thank you for that. Does it detail anywhere how this is calculated? Given I'm on oil and the price goes up and down like a yo you, how does one work if out? When I've done calculation before I can double of halves the payback just by changing the price of the oil. And more importantly demonstrate to the BCO? Maybe you think I'm over thinking it, but I absolutely don't want to get into a debate with the BCO once I'm into the job. Simply because if the disagree I have no recourse to challenge that
  23. Roger440
    Which part are you looking at please? It clearly states that the BSR applies to all buildings, both new and refurbishment, as well as high rise buildings. As far as the penalties are concerned, they are not confined to hrb's as far as I can tell.
  24. Roger440
    That's not my understanding. The new arrangement means that enforcement if building regs can take place up to 20 years. I get that the new arrangements were to a large part due to such things as grenfell and the blantent disregard of regs by developers, but the enforcement powers apply across all areas.
  25. Roger440
    I appreciate the reply. However I'm thinking I'm more confused now than before I'm not sure I really understand how any of this doesn't require BC involvement? If we take the insulation specifically, my understanding is if more than 25% of a walk or a ceiling is disturbed then I need to comply. As I intend to take a while house approach then surely I must comply to some extent. The phrase in so far as reasonably practicable, is great, but is wide open to interpretation. The issue is only the bc's view is actually relevant. It purely luck who I end up with, and therefore how much it might ultimately cost Once I engage with them, I'm on the radar at that point. If they want me to do things I consider wrong or unaffordable, and I then choose to proceed another way, they will know that it is likely I've done just that. Under the new rules that came in last October, if I ignore it, and they know, the potential penalties are extreme to say the least If they don't know, then nothing can happen. The only way anyone would ever know is if I subsequently got another eoc which would show a large improvement! My experience at my last place is that the various certificates were worthless as none of the work complied fully, in one case, not at all. So what value do they really have? Especially as it's almost impossible to take action against BC for negligence
