No. an actual test must be done. However I have doubts about the ethics of some testers...and contractors. Alternatively you can elect for no test but must apply a very onerous number (15) to the SBEM. It is a rather different setup though if the building is 50m x 20m x 10m, for example. @ProDaves car fan and cardboard wouldn't do it. I always had foam strips ready fitted. I'm shocked to now see on Kingspan site that this is optional. Other suppliers also had them as standard. perhaps this is a race to the bottom. Optional factory-applied side lap seals just a thought. Some industrial units are built to unheated standards then converted (sometimes without planning) to 'ancillary office' use. Or occupiers install space heaters.

Double the cost of the whole building. Treble the cost of any one storey. Plus I, as a contractor, would add risk money. Anything that could be a problem is multiplied. That also assumes a clever and practical design. I was looking into a hole while on holiday (as I do). This was a deep excavation for a basement. But a it was in a dry area of Spain, with no water table concerns, and self supporting sides, they just dug a hole and used clay block-work for the walls, and the usual concrete frame holding it all up. That will still cost more than an upper floor, but not much. In central London, dig a basement. Perhaps central Edinburgh where it isn't rock. Elsewhere, no. I've done one. Not good value but the client owned the site and wanted more space. Plant and kitchens went in there. It was a pain throughout, especially as it, being watertight, held the rain in.

They have an interlocking joint with foam strip so the long edges are not a problem. Therefore it fails the air test, and badly. But you are right then that somebody, or many parties, must be turning a blind eye..or worse. I was getting a building pressure washed yesterday. I supervised a lot of the construction (14 years ago) When it got a decent air test result. Yet there was water coming in at window heads. Not a lot but some. I have no idea whether this is a good comparison, as perhaps the jet broke a seal. That applies to all construction, and all manufacture. Who is responsible I wonder, for what you are seeing. I should say for clarity, we used Polish then Hungarian cladders. Because of quality, not cost. They are no longer available. There are some good UK ones too.

Report back please. I didn't know these existed.

Photos! Faces pixellated of course.

Evenn If its asbestos, I can imagine you were breathing it in, any more than with plasterboard dust. Mist of it us cement, and that type of asbestos is low risk. Damp cloths to pick up and remains. And relax. Do get the test done.

I've not met a refrigeration business ( in about 8 projecrs) who understood the science of it. Like many trades in the industry, they had been installers fof a while, then started their own business, which was joining up plumbing stuff and insulation panels. As implied, they were barely technicians, let alone engineers, even small e. I'm sure there are good ones who lose tenders to the cheap ones. This discussion is concerning.

If the chain is long, it might pull across to a favourable position. definitely, regardless of your steadiness. The ladder moving is more worrying and distracting. has anyone used one of those multi-position ladders?

No its not. And you are right to tell us off for acronyms without explanation. ,But you started it with ASHP. Good luck with the EPC currently TBC.

The most useful for a new C of W in my opinion, having the background of picking up the mess of previous trades and working alongside the other finishers. Other trades may disagree!

What they said. It is standard practice to have a builders' supply, metered or not. This does not trigger council tax.

Something I know a lot about. Industrial buildings vary. At its simplest it is keeping the rain off, with no need for any insulation. eg a waste handling shed. A timber warehouse actively encourages airflow . Avoiding condensation dripping from the roof may be allowed for with the tiniest amount of insulation. At the other extreme are high quality retail eg you don't want any cold or damp in a sofa shop. ditto call centres and offices, although called 'commercial' rather than industrial even if built much the same. In-between there are any level of air-tightness and insulation that may be appropriate. Composite panels to achieve a B rating will probably be 200mm thick, very expensive and requiring a lot of lorries. Then they have to be fitted by crane. thus a built up system becomes favourable. The labour is reduced but not enough. For a more background amount of control, a 60mm or 80mm panel can be used, but this may need supplementary insulation inside. Do they get wet and stay wet. Yes. they shouldn't though so this is workmanship and supervision to blame. In reality, the insulation is laid just before the top sheet, and isn't sitting in the rain for long. On a day like today they should not be laying insulation rolls, and i doubt if anyone is. They will be on the ground sorting panels, preparing flashings or reading the paper. On walls of built up cladding, the outer sheet is not sealed, so any damp will dry out. As appropriate. There are proven standard details for air-tightness, and the air loss is part of the SBEM analysis, when required. @Roger440Where do you think the leak paths are? i'm happy to expand on the above if you want. On a barn conversion i would likely recommend 80mm PIR composite panel, with additional insulation inside. OR built up system, probably 150mm, and again some inside supplement. OR an osb roof on timber rails, then spacers and the metal cladding only keeping the rain off, and lots of insulation inside.

Quite progressive. But then Scotland had a big problem with landowners, usually English ones. 1. These were SE England. 2. N/a but....More likely technically Scottish landowners, long moved south, just coming back for births and shooting.

I'm grateful for you introducing me to this product. So I've looked it up for future reference and it seems to be £20 shipping. Maybe the wrong size of the product.

OK that's what I imagined. My response stands including that the colour will be inappropriate. Don't ask me for more suggestions though, as I don't like or favour pastiche in construction.

The ones I have been involved with were groups of 4 in a terrace. Built by a builder / developer for sale. They then repeated the process further along the road as the town expanded. The construction principle was standard, with only the brick and decoration varying. I can look in a very old construction book and see all the same. I wonder if the builders even needed any drawings.

A new term to me, better than what I was about to say....the slums have long been pulled down if they hadn't fallen down. Most 'nice' Victorian houses are terraced, built for the rising middle class of merchants and tradespeople, to proven designs, using quality materials, and mostly well maintained thereafter.

All as above, just improve whatever you can. Put side screws into the hangers to keep the joists from rotation. Screws like those shown where they clear a hole for themselves in the chipboard, then countersink themselves tight. The bubbly, expanding kind of joint glue If the floor is bearing on the noggins then I think a screw through there too.

A faux one? If that helped sell, they would, but there is so little outdoor space that there is nowhere to put one.

No. But their formula includes these to make them 'traditional' and part of the package they believe makes money. Fibreglass birds on the fibreglass chimney pots are, however, not considered.

For me, timber box on top of the insulation, pinned in place either to the pir or through into the sub base. Then it's worth filling with sand or bricks etc to keep it solid against kicks or the weight of screed. If you make the boxes to suit, they can be unscrewed and come out neatly.

This is the developers not the government. Most are fibreglass pods screwed onto the roof. I have moved for them to be omitted but thd developers think they help sell the houses. Planners didn't object, in fact it hadn't occurred to them.

It's easy to get steel cladding pressed in tile shapes. Just google tile effect cladding. For what you seem to want you would need a layer of it, then a spacer system with insulation, then an outer sheet. The back is usually off white or grey, so might still not be what you want.

Old Macdonald's Law applies Energy In = Energy Inevitably Out

Quite right too. As for maps, they can either be easy to open at any point, or need to completely opened every time. And if folded properly, the title block is visible. Might as well do things well when it's no more difficult. I've been the contractor struggling to look at a drawing in bad weather. I've been the consultant, doing mass folding, properly, for issue.
