We're soon building a slab on grade foundation for our new cabin in Montana and I've decided to sit it on a 4" EPS foam insulation so the slab will retain some passive solar heat from the south facing windows in winter, avoiding having to put too much heat in to keep stuff from freezing. There's a bed of compacted gravel already down for the slab to sit on, so my question is, should I put a vapor barrier down before or after the EPS foam insulation and as there's a chance of radon what specification of vapor barrier do I need, plus can this do the job without buying something actually called "Radon barrier" and pushing our costs up?
