Hi guys, excuse a 1st time poster if this is in the wrong category please.
We are at present renovating an old police house for my daughter. Typically it will be a cold house although the extentions we are having built will be up to current standards.
All ground floors are dry solid concrete. but the big area which was once the old jailhouse, will form the base of the lounge so we want to ensure it is not a cold block.
The room concerned is about 7 mtr x 6mtr. We are about at the replastering/re ceiling/new upper deck stage, so more or less anything is possible but only if done quickly.
The bare minimum would be to add 25mm polystyrene insulation and overboard with 18mm high grade chipboard. The increase in height would be no issue. But I don't want to miss out on the possibility of adding a wet heating loop under the floor. The max additional height we can stand is 100mm.
So is it as simple as adding a 100mtr coil of plastic pipe on top of 50mm jablite or such, and 50mm of some sort of screed on top?. Manual or auto matic control needed of course.
I've tried th phrase this question in such a way that indicates I know my way round the diy game very well, but have never had any involvement with under floor heating other than the crappy basic electric stuff from such as wickes.
Any quick, cost effective help will be gratefully received :) :)
