floor covering on slab of passive house
How much difference does the floor covering make on solar heat retention? Intuition tells me that a stone/concrete/tile floor is best for absorbing radiation. I realise however that intuition is often wrong, and even if it’s right it might not be significant. I would prefer to have hardwood floors, but have been operating under the belief that having hardwood floor over top of the concrete is going to be a significant penalty in terms of thermal comfort and energy efficiency. I’ve recently read that in terms of in floor heat, the floor covering hardly matters. Is this the case in reverse, i.e. receiving radiant heat vs giving it off?
