Our property has floorboards over joists (very old baltic pine). We decided to rip our carpet and now bare floorboards which is starting to get air coming through. We are looking at putting in underfloor insulation. A bit confused about what is the best to get. Are the batts better than the foil based? and what about the moisture. Majority of the house is quite elevated - from about 1.2m-0.6m.
