Sounds like he thinks you're a footballer and has added Man City tax on top of anything he quotes.

Thanks @noseall As I already have the Vapor Control Layer. So ideally would like to use that, and then I guess plasterboard on top.

You are right, 120mm is not sufficient for the cold roof system, I have just confirmed this on the phone with my building regs contact. He confirmed your suggestion to append an additional layer of insulation to achieve minimum thickness of 150mm. I'm grateful for you guys on here, saved me a...

Hi Noseall, thanks for getting back - I'm abit confused though, so you think 120mm is not sufficient enough? As stated: - 7*2 joists - 120mm insulation --> Remaining air gap once insulation aligns with joists approx 55mm Opting to apply: - Expanding foam to any gaps - Vapor control...

Thanks your input mate, was this recent, I'm told we need to use a vapour membrane layer. We have 7*2 joists, so 120mm should be sufficient to ensure minimum 50mm air gap - is that the case?

Thanks for moving to the appropriate thread

After sorting out our ventilation issue in our flat cold roof, we are now at the point of putting in the insulation. I am hearing contradicting things at the moment, that we need to use gapotape due to the recent changes in building regs. or can we simply ensure the celotex is cut correctly to...

This isn't so major, it's just annoying/inconvenience. But we shall see - I appreciate all your comments.

I think you got it - the slope seems to just stop short. I'll get a piccy, to show you under the hood Do you reckon it will in essence though shorten the lifespan in the long run? Updated edit: Please see the image attached - you're correct it runs short of the final 2 or so joists... Is...

Thank you, I appreciate it.

Anyone, no course for concern?

Hi all, Now we've had a bit of rain, this is the state of play at the moment with the roof. Is this level of pooling normal?!

Anyone?

Yes that photo is the second layer that has been applied: IKO SBS HP Top Layer 1 Sand This has been laid in line with the fall.

Hi Diver Fred, Thanks for getting back I appreciate it. Yes, it seems that's the case it has been applied in opposite directions to the previous. Layers: - IKO Venting Layer Torch On - IKO SBS HP Top Layer 1 Sand - IKO 67440000 Turbo Cap Sheet Torch See images attached in order of how...

Anyone got ideas?

You can get someone to review it for you, but some one here with experience will probably give some advice

Hi all, Our roofer completed our felt roof last night, however we are unsure whether the application is going to be problematic. We have gone for a triple layer system which all is fine. However the issue we have is with the direction the felt has been laid, it should have gone with the...
