I believe that’s what the ufh company has said . Erm , that not the best ???

Perfect ! 100mm it is !

As if I know which one ! I *assumed* the depth required was pretty similar.

A breaker for 40 quid !!! It would break ! Got my Hilti for that !

Equation of faith goes like this : want bathroom + dont know exactly what suite + dont know what shower x not really sure how this is going to go / wife-factor Lots of variables not many constants ...

Better dig it up ?

Right ! It’s complicated ! Doing the ufh prep in the bathroom . How thick does the wall need to be to take a geberit hidden flush cistern ? Because we don’t know the exact size of our shower tray nor the bath type ( as in where the waste is or where the taps are ) i’m going to shutter out those areas so they have no ufh nor screed ; same for inner geberit wall . This a sensible plan given the situation? cheers

I’m ok then ? . Vcl ordered for non GF

Or girl friend ! ?

Ground floor ? Mine is “technically “ 1st floor

Pir isn’t eps though is it ?

You certainly have ! cheapest inc vat was around £54 You are in the money ?

150mm pir ordered ; cheapest I could find certainly not local builders merchants . Also found vcl ( looks the same as Permagard ) slightly cheaper . Double tape ( for vcl overlaps ) , tape for edges , foil tape all found cheaper on eBay

Done to @Onoff ‘s made up spec ! ?

Pir upstands done . Foam where I had to ; foil tape on joints . Osb on timber frame just so vcl has something easier to stick to .

Ufh company said expansion perimeter not required ; pir upstands good enough for that . Nearly done one room of upstands - not neat - but every piece of pir is an off cut left over - so free ? Mind you the 15 sheets of 150mm pir will be expensive ?

If I put expansion tape at the perimeter like this https://underfloorparts.co.uk/product/underfloor-heating-perimeter-50m-foam-edging-strip-5rolls/ Does it go under vcl or ontop it ? ( i’m Guessing ontop ! )

I *presume* I silver tape the joints on the floor between each pir piece ????

I see ! Right ! Vcl over the lot and up past the upstands . All taped got it !

Why can’t I just cover the whole thing in vcl and tape it further up the timber . Why do the dpc strip around the perimeter? Is the vcl thin and likely to tear ??? That why ???

They would be perfect for that ? They have no grip on the surface but certainly don’t seem slippery when dry . They are structural glass so strength not an issue ( BUY THEM ! )

Nope ! Never gonna sell . I might build a modern art sculpture and incorporate them into it

Yes very dangerous device ; Best Buy something gentler like some glazing for example ... ?

I got a special price thanks to @Onoff.... You can’t have it unless you buy some ‘certain’ glazing I have ....

Toys !
