Unfortunately the ceiling run is 15mm copper in that woolly blanket type insulation. I think it might be easier to change the pipe run than butcher the cupboards downstairs. It means it would go in a larger cupboard upstairs which is further from the boiler but closer to the en suites. How...

Thanks. I had earmarked the upstairs airing cupboard for the cylinder especially as it was close to the en suites but perhaps I should see if it’s feasible to put one next to the boiler downstairs where it should be easier to pipe 22mm between them. However, the room is a wall of 60cm wide...

Thanks for the advice. So now I’m worried. Once all this is done I’ll be painting rooms that were initially done with Leyland Super Leytex, specifically because it was recommended for bare plaster and had high opacity. Is it going to blister and come off on the roller? If so will an...

Thanks for the replies. So does it have to be 15mm all the way from the boiler? I could maybe run 22mm part way (first floor section) but it would mean too much tearing apart downstairs to get all the way. Alternatively, would a direct cylinder be feasible? Could that feed just the showers...

Hello I’m working on adding a couple of en suite showers but currently have a combi boiler which I fear won’t be adequate for the increased demand. From what I’ve read it seems I might need an indirect hot water cylinder. Am I right in thinking a cold mains feed into it is heated by a coil...

Hello I’ve had a lot of plastering done and I want to make sure I get the painting right. I plan to use Johnstones Perfect Matt colour as the top coat but was going to use a matt white mist and undercoat first. Should the base coats be the same brand or at least a good quality paint (and...

Sorry, I was reading on my phone and didn’t notice the link. Thank you, that’s very helpful

Thanks for the replies. Would fish pond /bird netting be up to the job?

Thanks, so are you saying the finer the better? I was about to buy this: Baling twine Wasn’t sure how thick or how big the gaps should be.

Could anyone suggest how thick the twine should be and the spacing needed to stop the insulation sagging? It’s Knauf 44 100mm. Thanks

No, just the ceiling rose. But where I’ve installed down lights in the bathroom I’ve used LED ones with a guard and left a bit of space around them.

Thanks for the replies. Perhaps not the best but better than a void

Hi I’ve got some Knauf 44 thermal insulation rolls left over and I know they don’t have acoustic properties but is there any point in putting it in the void between the kitchen and the bedroom to help absorb the sound of clattering pots and pans? It’s a deep void so even doubling up the...

What about something like this, cut to a couple of inches wider than the joist centres. Staple it to the side of the joists so it forms a cradle? That said, I only took a couple of boards up to install a radiator, insulating it will mean getting the lot up!

Thanks. I suppose I should be calculating the entire void, and not just the room. A couple more should do it.

I think I'll tackle it myself first, I can't be doing with Building Regs and Social Services on my back ;)

As regards clearing the rubble, there's all sorts down there. Can bricks and the like stay? All in all it's cold down there but not musty.

Thans Deluks, I'll give it a go. I do have sleeper walls elsewhere, but the gaps are brick size, in a chequered pattern. I hadn't thought of insulation but now you mention it.... I presume it'd have to be PIR board? What's the minimum thickness I could get away with for it to make a...

Thanks everyone, I'm so glad I asked, your replies have great advice (y)

Hello I've currently got some floorboards up in a ground floor utility room room which wasn't previously heated but soon will be. In the external cavity wall there's an air brick to the outside. I can't see from the inside but I can stretch towards it and feel a draught so I assume it's...
