Hey all,
I know there is already a lot of info around on this but it is hard to collate and then make sense of (for me anyways!!)
On a new self- build, with regard to floor insulation, I will have UFH downstairs and so have decided to put 125mm insulation on the Ground Floor, then the UFH pipes and then the screed of say 65mm. I read somewhere here that it is best to put this 125mm down in layers with joints staggered, so how would 125mm be best broke down into layers? i.e. in 2 or 3 separate layers?
Someone mentioned to me that I should prevent heat loss into the walls and foundation by putting 50mm insulation in around the wall perimeters also. How does this work?
Does this go in standing up vertically along the walls of each room to a height of 125mm with the horizontal layers pushed tight up against it, so that after the screed is poured, the screed covers over the horizontal insulation and the top of this vertically standing insulation?
Am trying to save expenses, so am I right in saying that this is something I could do myself? Once floor slab is level and cleared completely, could I do as outlined above, making sure everything is put in tightly and then let the Plumber in to do UFH?
Upstairs, I will have a concrete slab floor with room heating by Radiators? Firstly, do I need to wrap the slab in anything to seal from below? For floor insulation here, I presume that you would not need 125mm here though? What would the recommended be to achieve a good level of insulation or given it is Rads , do I need any at all? Do I also need to do the vertical insulation here if the rooms are made up of timber studding?
Thanks for any help,
