shackles

Thank you for the responses. I had read various articles on different websites stating that 100mm did work well. Then I posted on a Facebook group and everyone said I was crazy for even mentioning 100mm and that the UFH will not work in that depth and that it was a waste of money etc etc. I have seen people mention the NeoStat WiFi thermostat with the hub - is this a good option that includes 0.1 Deg hysterisis? Never heard of this before. Thanks.

Hello, Having my extension floor poured soon and have had conflicting advice from various sources. I have 150mm PIR with UFH pipes stapled to it at 150mm spacings. I have allowed for 100mm of screed going over the top. Some people say that all you need is 50mm of screed and that the UFH won't work properly with 100mm... Does anyone have UFH pipes in 100mm of concrete or screed & does it work ok? Cheers!

Ah well that's good to know and easier to do. Cheers.

Hello, Yes - I think I may go for a black composite board fixed or similar to hide it. Or brick slips if I was that bothered also...The bitumen would work, just not sure how it would look after a year or 2 etc. Thanks.

Hello, I have planned to use marmox thermoblocks to reduce the cold bridging from the blocks. Cheers.

Hello, thanks for the response. That would definitely work if there was a masonry outer skin. However, it's not really in the budget to add on 50m2 of facing brick work right now.

Hello, Got planning for a single storey kitchen extension & I have decided to build this in Timber Frame. I have searched for a design detail of this but I am yet to find one. Maybe this is obvious... I have not started this build yet and just want to get my head around the design. The design I wish to proceed with is 150mm timber studs / sole plate. My question is - If you build the timber frame extension off the concrete blocks - are the concrete blocks then hidden by cladding that cloaks over the top? Even the cladding is inert / cementitious, I still don't like the idea that it is that close to the ground and could somehow breach DPC or just get covered in dirt. I know you wouldn't have this issue if you built off of engineering bricks, but fixing the sole plate down to engineering bricks could risk damaging the engineering bricks / cracking etc. Or is this fine and not anything to be worried about? The image below shows a SIPS on concrete blocks. This is an example & not my build. Any advice welcome. Thanks,
