I suspect they are all much of a muchness, I think I got all mine from Wickes who don’t seem to stock them anymore. Perfect for that level access with no drainage problems. Perfect for when you change your mind about the patio shape. Perfect for when you drop something really heavy on to a tile and damage it, 2 seconds to lift the tile and replace it.

If my experience is anything to go by then mistakes will be made - nothing major, though every small mistake seems enormous in the moment. Stress will be high. But, without a doubt (for me, with zero prior knowledge) it was definitely the best decision.

No recommendations apart from have you considered managing the project yourself? It’ll save you a bundle and you will more than likely pay much more attention to what is going on, and what soon needs to be going on, than any professional project manager.

Do you need those? It’ll be plenty light enough in there with the windows you have planned, those roof lights will just add complexity and cost (and maybe leaks) and be noisy when it rains. Wracking my brain for a ‘positive’ but can’t come up with anything.

Why not go for a flat roof, wouldn’t doing that solve your problem? EPDM is very DIYable.

Holy sh*t, and what a noise, has he left a spanner in the pump?? I’m sorry I can’t help in any way, but do go in all guns blazing tomorrow.

Yep, this stuff. It was around -2 when I took the photo and been negative temps for about 8hrs I think. I didn’t think +10 was too bad but I haven’t done the sums (Steamy will do those I suspect). Actually the foam is probably a degree or so warmer than the +10, that coldest spot is the plastic Ubbink connector.

It’s chilly and foggy outside and the ‘Mk2’ insulated pre filter box is performing admirably. The Ubink insulated ducting being the coldest thing in the MVHR room now. It did seem to seem to be noisier/running faster than normal. I had my suspicions that the pre filter mesh may be getting clogged again, I also had my suspicion that freezing fog may be having an adverse affect on the air permeability of the fine mesh… Turns out the freezing fog was playing a major role in restricting air flow.

All went well in the end. I know some on here have had a good experience with Fermacell, they are probably more experienced in that kind of thing. Me, as a rank amateur, struggled. Good luck with whatever you end up doing.

Yes. Every little helps.

How can that be possible in 5 years? I guess only via dodgy installation/commisioning?

The red bar thibgy won’t move unless you move it. It’s a marker to show where the black thibgy should be. You should never need to move it but it can be moved to indicate a different pressure by using a screwdriver in the centre.

I would say stick with experts here (me not being one of them). This is not rocket science and I reckon you can fix/fault find this yourself - with the help of the smart people on this forum - and then you can either cure your problem yourself, or tell a ‘professional’ exactly what the problem is and what you want fixing.

I would call that brand new. Ish. It looks like @ProDave has got your back to make sure you’re not being scammed.

Isn’t it all brand new??
