I'll be using these as I seem to have loads of them in my shed -

Hi all Thanks for your replies. I think I'll use foil backed plasterboards, foil tape over the timbers where they join, and foam up the edges. And also bring a plastic membrane across the plywood section and up the front with that being all connected with foil tape too. The good thing is that I...

100% correct there - it is a warm deck flat roof. I know we can get DPM in liquid form (i.e. Blackjack etc), and as this is going to be in a protected space then I'd be surprised if there isn't liquid VB too, although it's not the traditional method used.

Hi I believe I need to put a vapour barrier above/within a small suspended ceiling I've made. The area will be used for kitchen things and I'm expecting I need to protect the main roof joists above from the condensation of cooking etc. Trying to thread in a plastic membrane is going to be...

No I'm doing this in my own house, but so long as it's done correctly then there shouldn't be any issues if money changes hands or not? I'll obviously do a proper cert when done.

Thank you very much for your replies guys. I have the ticket but not yet the experience and so it's reassuring to get a 2nd opinion from the real experts :)

Hi I need to connect an oven and hob, I've looked at the regs and calculations etc and can't see anything I'm missing or wrong, but if someone's kind enough could I get a second opinion please? Oven is 5.9Kw / 25A Hob is 7.4Kw / 32A Cable is 6mm T&E (clipped direct) which should allow max of...

Cheers Steve, maybe I'll use a thinner cement board as backer in that case as there's the depth of the backer + the tiles + adhesive to consider. Studs are 300mm apart so I'm sure that'll be fine. The wife *always* chooses the wobbly edged antique underground brick type of tiles - which makes...

Hi I’m rebuilding my kitchen and have to insulate the outer brick walls so I’ve put up stud walls with celotex between the stud timberwork. But I’m undecided what to put over the studwork on the inside face. OK so it doesn’t need to look pretty beneath the kitchen base units, but I’d rather not...

Thanks for all your replies. In the meantime I found this which gives the charts - https://hspfireprotection.co.uk/information-and-advice/4_fire-ratings-explained.html To me, if it's C-s3, d2 then that seems to translate to it being acceptable to produce a high volume of smoke, acceptable to...

Hi I'm planning to install MDF cladding internally on a new vaulted ceiling. Buildings regs have just come back to me and said the following - The ceiling of your residential extension should be protected to resist the spread of flame over its surface according to classification C-s3, d2...

Hi I'm always confused by vapour barriers.... I have a kitchen with a flat roof (warm deck as it's insulated above), and an adjoining blockwork wall. The roof joists are currently exposed, and the internal wall will be battened up the blockwork and PB on top (no insulation) as it's a very...

I guess when people like myself are in the position of having done so much work already and purchased all the gear then it's going to be nigh on impossible to change minds! I'm thinking of this as essentially an insulated stud wall on it's side. All the walls will have stud walls (because if the...

Hi Ree Thanks for your compliment :), that's the part I know but unfortunately the rest of what I need to do is a bit of a haze to me! It's 25mm ply that I've already got and have allowed for that to get it to FFL where it blends in to other rooms. I get that screeding/SLC would be good in...

It was a can of worms me buying this house in the first place TBH! According to my understanding the building suffered settlement with the levels partly due to a very large extension being attached which pulled the entire building to one side and because it's all built on peaty soil with part...

Hi I'm just building a frame to make a floor level - because the original house floors drop away quite significantly. I've laser mapped the floor and cut the fillets to measure, the end nearest the door skims down to a few mm and then on to latex, whereas the far end has raised about 7" (it's...

I've read this since and mine show a frosted red appearance, so I presume they're ok? From what else I read, the older units used to have a green/red indication but the newer ones just have red coming forward to the front of the window. Isn't it great to know the safety of all my electronic...

Hi all Thanks for the replies. I was a bit wrong with dates - the SPD was fitted in Nov-2022, but still is less than 3 years old. The supply type is TN-C-S therefore one of the modules would be redundant as it's shorted by the E-N link at the service head. So really if that 2nd module is red...

Hi Yesterday we had a brief power cut for a few seconds. Apart from finding I was now the lucky owner of two dead computer monitors, on inspection of everything else I see that the Hager SPD's in my CU are showing red on the indicator panels. Hager say they are "end of life" - so does that mean...

As the question, every time I buy something from Screwfix I get the emails asking for product reviews with a £250 tempter, but I don't know of anyone who has ever received anything. Have any of you been lucky? I don't mind leaving product reviews if it helps someone else out, I kind of dislike...
