Insulation

Jacqueline of New Orleans:
I live in an old, elevated raised home in New Orleans. During the winter my floors are quite cold. I block the outsides of my house to keep the wind from going under it but the fact remains the floors are still quite cold. I am comtemplating putting some sort of insulation underneath the flooring in the hopes it will warm them during the winter. But I am worried about condensation building up.

Someone advised that I can use the new styrofoam that is used for wall insulation. If I crawl under my house, can I attach this styrofoam to the underside of the floors and will it work? My living room floor is hardwood, the rest of the house has linoleum. I appreciate your help since I am not in a position to hire a contractor.

Styrofoam or similar board insulation has 3x or more the R value of fiberglas, I believe. You should refer to a insulation contractor for costs and efficacy for either. Use the Web to locate a general membership organization for insulators and/or insulating contractors. These types of groups are repositories of information for the trades they represent, and much info is often freely shared with the public.

Foamboard is easy to work with -- it's light and has none of the irritating qualities of some types of insulations. You should have no real difficulties working with it. A tight fit is important. Also, fire retardant quality may be an issue.

You can also check with your local municipal building department to see if they can advise you or point you to relevant resources.
