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.

In the standard contracts there is a line to fill in for 'liquidated and ascertained damages. LADs Of course the contractor will try very hard to avoid delay, but also to justify any delay that will allow an 'extension of time'. EOT Surveyors battle over this. There used to be some evil contractors who endeavoured to charge their subcontractors this way, and I expect some major clients did the same. The lawyers gained. With 'real' clients, ie decent people trying had to make a living, I would explain about LADs. and that we already lost money if the job runs on. If LADs are insisted on then 1. we have to fight them rather than gt on with the job. 2. will add a few weeks of that value to the tender, as risk. 3. explain that if the deadline is as importnat as they say, then they should have started sooner. With corporate clients I simply added the risk as a likely job cost.

I'd say this is a minimal issue. The walls will be made of big lumps of stone, and yours don't look porous. so any damp would have to rise by capillary action through the mortar. That is actual suction taking the water upwards. It fizzles out over about 300mm. The central core will have gaps in it sufficient for draughts, horizontally and vertically. this might affect the air-tightness of your home, but will reduce damp: its a compromise.

I've been using LEDs from before they were standard, to test them before imposing on clients. Back then there was no guarantee. They were really rubbish for a couple of years. then they became more reliable but the occasional one would go bang, sometimes with visibly black cells. when they became mainstream they were much more reliable. Heat used to be the biggest problem, and I was informed that it was because cheap lights had glued connections and not soldered. so that may still be the case with some. If the lights are concealed in the ceiling then they could get hot. This may be extreme if they are in among insulation, or have a fireproof hood on them.

I think that in Germany you can deposit packaging or end- of- life products at the retailer, and they must get it to their supplier und so weiter. Hence all German cars have every part marked with the material content. It will work as long as it as easy as dumping it, and if there is a fine for binning it.

Thanks. I'll remember next time. Could just about do the return trip in a day. The pipe isn't especially expensive at about £1/m, but it is wasteful and will now clutter the garden. Surely they could sell it at £2/m cut to length? And it would be visible corporate sustainability if they had an oddments bin, free to regular customers. I remember from doing work in London that plumbers carry zero parts, and there seems to be a tiny merchant every few streets, selling pipe cut to length. Ditto electricians.

Do the floor boards run parallel with the party wall? If so, you could lift one or two and stuff the ceiling space with insulation. Stop press. Picture just in. Can you confirm what we are looking at?
