Ah yes good point. In my head I'd just lumped pedestals in together with rails as: things that support slabs and (potentially) make my life easier. New question: anyone got experience of pedestals!

Anybody got any experience of laying a patio / slabs on a rail system? I am (probably) going to do a patio later this year and contemplating using something like this. Seems like it helps with drainage next to the house and would be a lot simpler to lay (as long as the pads are on something solid). Something like this: https://www.rynosystems.com/pave/terrasmart-rail/

For design I got a lot out of loopcad in a Virtual Machine so I could do repeated trails.

You can do the very slow and boring resistance testing.... Disconnect at CU completely, then test resistance between cables pairs at every socket and see where resistance is lowest. Might tell you when you are closet to problem.

Before I decided to install MVHR I was going to go outside and use a Naber Compair tower as an outlet. Had all the baffles and nice things to not leech heat. In fact I got as far as buying one that's still sat in my garage.... https://forum.buildhub.org.uk/topic/42930-naber-compair-tower/#comment-604747

I'm not sure you need membranes / materials for a lot of that, depends what exactly you are doing. Probably just a normal polythene DPC between block and beam and insulation Insulation that's well taped and foamed might not need anything above it before liquid screed. Normally the membrane (if used) would be above insulation, below pipes. You want your pipes to be in the screed to transfer head. Re between screed and floor - depends what wood. Some supplies will want a super level finish before wood and will apply a smoothing compound, some planks can go straight on top. Hope it helps.

Before I have just used contact matt as a mist coat, but realised with some modern paints to need to use the right base coat / primer as some folks have had issues with contact matt as a base coat and paints peeling.

Slight tangent. What paint are you / folks finishing IWI like this with? I'm looking at using something breathable which rules out the normal vinyl Matt etc I think.

If you do this run it in a VM. Cracks / keygens are a great place for "added value"

Then hopefully heat pump / fan coils next year 😄

It's slowly lost effectiveness over the last 3 years, so if I can bodge this summer I'll be happy!

Any body done it? Our portable air con unit that is only used a handful of times has been getting progressively less effective, and on turning it on tonight it is now ineffective. There seems to be inexpensive kits / gas you can buy, but interested if anybody has successfully recharged one with R290 propane.

@SpinnyDid you resolve this? Excuse my stupidity but was the actual door system ok and just had install? Or system flawed. Reason for asking as we are planning on an eclipse door system, but now may change our mind...

But - our house is 1980 and we were sure the only asbestos was the artrex
