Or was it 50mm Screed with 50mm insulation underneath (the only way I would do it if doing screed). 300mm slab sounds excessive, beams yes but the whole slab, I would get another another engineer. Yes double studs would be ok for edge. Curtains are a must, I'm trying to develop an insulating curtain. I try to make the Zones equal distance in pipe; there is no way I would rock up to start laying pipe unless just labouring, must plan. Extruded polystyrene I think 30mm is R1 which is around $20 m2, this should be used for edge slab. Good luck Pulpo Re: Hydronic heating what you should know!! 19Aug 14, 2012 10:09 am Pulpo Regarding edge insulation is highly recommended http://www.heat.net.au/action-advice-pa ... on_web.pdf Extruded polystyrene I think 30mm is R1 which is around $20 m2, this should be used for edge slab. Pulpo That's what we're planning on doing ie. use extruded polystyrene for edge insulation (and also for the slab). However, we've got problems trying to work out how to seal / keep the whole thing air tight. Our renovation would be an alteration and addition type, where original front of house is kept but reconfigured as predominantly sleeping areas and an open plan extension added to the back. Because we're located at the foothills, the back of the house is on a slight incline so the back slab of the house will be raised to keep the floor work inside the house all at the same level. The problem our architect is trying to work out is how to keep the edge insulation contained given that it will be 'exposed' above ground as opposed to it sitting inside a trench sandwiched between concrete and ground. There's also the problem of the insulation jutting out from the external wall below. Does that make sense? Thus, will look awkward aesthetically plus will assume the insulation will need some sort of cladding to cover it as well meaning will extend out even further in comparison to the external wall.
