Normally perhaps but it shouldn't be. It is hydraulics. The manufacturers publish flow rates. The number, position and quality of outlets makes a huge difference. As does shoddy fitting that isn't level. The rainfall data is in the building regs but it is wise to allow for the recent increase in continental type downpours. I ask myself what if... There is an exceptional storm The gutter is dirty There is a blockage Where does the water go harmkessly? Ask away.

Hang on. I know what you mean. But if you are using energy to get rid of energy that isn't an efficient multiplying of energy in/ energy out. Is that still the normal terminology for chill-stores etc? Presumably this was solar gain heat but it wasn't so hot outside.

Yes that would be, but slinky types are actually getting heat from summer warming and not the earth's warmth... so solar really. Is your sand glacial esker? The only ground I've known where soakaways had to be designed to run more slowly. (Except chalk which can be a problem)

Explain please why it is wet? I can think of pressure relief valve on a hot tank, but would tundish that if necessary. We have not designed ours plant room at all, so this is timely.

If only we could store that for next winter. Actually it us the one thing that is useful about slinky ground source. Warm the earth for later. Where you live, above 22C is getting too hot for most people. I was travelling in 32C yesterday and ok with it. We get used to it.

And AI might not find that crucial information. I guess the likeliest problem would be that trawling could as equally find outdated or false information, as factual. Yesterday planning a complex journey, AI told me to change trains to platform 1, (stairs and a bridge) instead of platform 3 which was 5m away. But fortunately we asked a person. A useful lesson. Somewhere there was a totally wrong bit of info it found. Now to find what material and colour of carpet she wants, given the reduced choice when considering open textures. AI response: "Your wife will ' know it when she sees it', and this may involve visits and repeat visits, to many retailers". Well yes, but thick carpet over underlay will reduce the effect dramatically.

Unless you are dozing it, use the term dismantle and it may help.

Exactly the same logic. They are generally in compression from the floor above, or just supporting cupboards, but the strength thing is the same: there is plenty if hollowing the regulations.

We all use inches on conversation for convenience. But these dims don't exist. The sizes are sold as advertised in mm. I phone the B M and ask for 20 lengths of 4.8m of 6x2. They don't ask if I mean 145 x 45. For heavy structural timber it will come in sawn finish. When dressed to avoid splinters it reduces in size but not a lot. There was a time when most timbers went through a bending machine which translated approximately to strength. Then this was samples, then by sight of grain and knots. Now we just sort of trust it. But C16 and C24 are visibly different. I would think that an average timber selected at random then tested for deflection and to failure, would exceed the rated strength by a distance because of various factors of safety which combine. And then we allow safety factors in the design loading.

Tiles will be best overall in cost/performance terms.

1mm gap in our weatherboard seems to be enough. Which reminds me I didn't fill over last year's. I can see the point, as a direct batten contact will hold water, then algae and moss. Fine if you want to see it revert to nature as some Architects have been heard to say to justify "eco" products. All these ledges would need a lot of cleaning otherwise. @Alan Ambrose what type of timber? The £1700 would be a lot in comparison with pine, but not with more exotic types.

It won't open for me. Anyway, between us we have found a few interpretations. Authorities can't make up their own rules so these are their interpretation and could be argued with. I haven't done the important thing of looking at the actual regulations. It's the sort of issue that tempts one to just do it, which is generally a bad premise. By which I mean that the OP intends to make sensible improvements but what if the bco refuses or demands something else? And yet, it would be possible to cause harm and that should be controlled.

Another thought. You can buy netting again a BM. We havd some blue kicking around. I think it is to keep debris contained. It's not expensive. Debris netting,: that's it. You could lay this across the joists, tucking down the sides and stapling. Then any wool material would stay put permanently.

I don't think that's right. RdSAP is for older buildings with no drawings or tests. That isn't what is being discussed, unless I'm misinterpreting. from the briefest look at the method, it is for where drawings are not available. Even then there will be different efforts made. The £100 fee guy won't want to put any thought into it, but the thorough one can. With that logic a passivhaus wouldn't get a better sap than others.

I think we could easily argue against this being required improvement to regs. 1. Not 25% of the thermal envelope. 2. The concrete slab below is part of the thermal envelope, not this raised floor. It's a good idea to do it though.
