It's around 60mm at the tightest point, partly because the wall plate had to be raised owing to the truss design. I've spoken to the BC inspector and he has said with the need to keep insulation away from the felt (what is the required gap, 50mm?), that the main thing is to have insulation to...

These might show better what I mean about the limited space between roof membrane and top of wall plate...

Thanks for the replies! The roof insulation will be the usual roll stuff, 100mm and 200mm above the ceiling board. Roof covering is concrete tiles above Vent3 membrane. Soffits are vented. I will get him to address this cold spot area. The only trouble is, there isn't much room between the...

Roof insulation hasn't gone in yet so I'm keen to ensure we proceed correctly beforehand. So are you saying the Roof insulation needs to go over the top of the wall plate and meet the top of the cavity insulation? Presumably something is needed to keep the roof insulation off the roof membrane...

Hi all, My extension is now having the soffits done. The inner block skin is noticeably higher than the outer skin. The wall insulation finished at the top of the outer skin. I asked the builder how the top of the inner wall would be insulted given there is a good 30cm above the wall insulation...

Ah, I see. Thank you. He will have to use fibolite then. Thanks again.

Thanks for all the feedback, very helpful.

Right, but as I pointed out in my original post, the commons would be at the top of the blockwork, above the wall insulation. They would be at or above ceiling height. So are commons fine after all?

But why would one course of commons matter when a whole roof will be sat on the same block work?

Why do they need to be aerated?

What are these reasons out of interest? Just so I am armed with the best info when I talk it over with him.

So is the problem weight? But if the blockwork is able to hold up a roof, what difference would a single course of commons make? If he uses the fibolite blockettes instead, which I think are the same size as a brick, is it OK for him to use the 4x3 plate rather than 4x2?

Hello, We are having a house extension built, single storey with a hipped roof. The builder has built the inner skin block work up (fibolites I think) but found that there is an awkward height difference from the current top of the block work and the wall plate of the existing bungalow, which...

Thanks for the replies. So the new pipe on the driveway side will connect into the pipe that comes off the meter. He won't be directly connecting it into the meter itself. The meter is within the footpath and is about 2 feet from the threshold of the driveway with footpath in between. This...

Hi all, I'm getting 32mm plastic pipe moled under my drove by around 20m from the water meter to my house to improve flow. The guy who is going to do it is very knowledgeable. He actually works for a gas company in Yorkshire, but does water pipes and such on the side. Said he can do it for...

Hi everyone! Myself and my neighbours are only getting 7.5l per minute cold water flow in our homes. This is rubbish. 15L or more is considered good, we are barely at half that. You can have a decent shower, but somebody running a tap in the kitchen interferes. The garden hose is a joke. I see...

Thank you for the comments, chaps. I agree that, in principle, a timber shed shouldn't need it because of gaps and such. However, there are not many gaps at all in this one, which is a tongue and groove structure. People do get mould inside timber sheds. I've been finding it inside my...

Hi all, My new timber shed is in place. It is the usual cheaper end, storage shed with a felt roof. It is a pent roof as well. I want to ensure there is ventilation and air flow through it to prevent damp and mould. I was thinking to drill some 70mm holes holes and stick those plastic louvres...

I wouldn't swallow toothpaste, it's full of fluoride and other stuff and the ****e I've just removed from my teeth. I take your point about the sink though. I'm interested to explore the wet room idea, particularly as this would be next to the utility and entrance so could be used as a...
