Downstairs in my house I have exposed wooden floorboards which are great, however in winter time they do get a little cold. With heating prices going up I have decided to insulate underneath them. (There is a space about 1 metre high running under the house). Firstly would this cause any problems such as dry rot or condensation under the floorboards or in the house? It is quite cold and airy down there.
Then there is the question of what to use. I was thinking of the yellow foam insulating board covered in the silver foil, Polyiso is it called, that I could cut a little thicker than the joists and push into position. I have heard that Polyiso is the most expensive of the foam board insulation. Therefore are there effective cheaper alternatives or is that the best thing to use. I also want to bear in mind the ease of doing it rather than choosing a method that is a load of messing about.
Any advice, do's and dont's about this would be greatfully received. Thank you!
