@saveasteading thank you! Any concrete?

@Andehh thanks for the detail. I appreciate your point and will take a more holistic view re air tightness etc. @jfb, thanks for the suggestion. I will ask for this to be done. Although, I am now leaning more towards @Iceverge suggestion of a 350mm dig out. @Iceverge, thank you so much for this. Anywhere we can save is very welcome, in addition to “less” work. I’ll be back with an update.

@Andehh, thanks for this. Those bills are encouraging! Can you share are a bit more about the challenges and limitations of refurbishing a 1950s house? @crispy_wafer, thank you. I hadn’t considered that. Will do now. @Conor, thank you. We are planning using the wet UFH system from Wunda. Digging in to the ground will also allow for us not to have to increase floor height.

Hello, We will shortly begin a refurb on a 1950s house. We would like to install wet UFH system. In order to do that, upon researching to topic, the advice is to insulate appropriately. To do so this is what we are thinking of having done: Dig up 650mm Hardcore backfill -150mm Sand blinding - 50mm EPS100 - 150mm DPM PIR Insulation - 130mm Concrete - 150mm UFH - 20mm Self leveling compound - thin layer Does this seem reasonable? And who would I need to engage for the works? I have spoken to a couple of builders who have tried to talk me out of more that 150mm insulation - we have not budged. Any advice would be much appreciated. Thanks.

Hello. I hope all is well. We will be embarking on our very first refurb project of a 3 bedroom 1950s house. So, here for some help and advice. Looking forward to engaging with you all. 😊
