we made a lot of money on the isar's !

I was thinking of running a silicone bead up there such as ct1.

@nod or anybody else with experience. We have 3-4mm gaps between the beads and window frames. Any recommendations on what to deal it with ? Krend pure white colour.

Just out of curiosity are we talking a full UFH type of manifold or just a old school micro bore type manifold? We are using a ufh type manifold on our upstairs rads so we can control flow temp from thermal store and no TRV's just room stats via phone app. I dont like painted copper pipes as it's very rarely painted nice (always paint over the valve nuts etc). I do like plain copper or chrome pipe especially to towel rails etc. I would not have push fit fittings on show either as the pretty bulky. Most of our jobs we took the white mlcp (uponor) plastic pipe rite to the radiator valve and used a chrome nut. Never had any customers complain. Ps carpet had yet to be fitted at that job.

I think it looks very nice but everybody's taste is different. We are planning to do a DIY with resin bound.

I would target 150mm pipe space. As I read your quote, the green, amber and red all use the same spec of pipe just different spacing and I am pretty sure wunda use pex/al/pex Wunda are normal pretty good but I think you can quite easily cut down loops from 14 on 115m2 floor. Possibly the easiest way to do this is use 120m coils instead of 100/80m. Throw your plans out to other suppliers quick rough calculations is £2k for UFH material.

Cheers all sorted now.

What's a acceptable distance for 6mm render beads from windows/soffits etc?

Not my favorite job🤣 we actually used stainless nails. We have a few clips left (normal and sliding) so if you need a few to finish of give me a shout (not looking to offload as will use them on next build but may just help you out finishing of job)

Tbh should have done horizontal but that's the 2nd felt layer, questioned if really needed it.

+1 on what Conor says. I thought long and hard on this (single block and 250mm EWI) and ended up with ICF but its still a option on next build. Would tie in very nicely to a insulated raft foundation.

A near by ICF self build who refused to have opening windows in a two story build had to install a sprinkler system. He done a few day course and DIY installed, pretty straight forward installation and it was respectable cost for material. I am planning to retrofit a single sprinkler above the log gasification boiler. Its in the garage with concrete block walls so not to bothered about water damage.

Your a star Peter, I didnt know the existed.

What have people done or planning to do for gutter/downpipe fixings? We have approx 215mm eps on the outside of the concrete. I dont know if to sink in some plyboard beneath the render or look for long fixings into the concrete.

I haven't used 1st hand but a lot of people on here have used wunda ufh.
