Insulation type spray or material on sub-floor before padding & Carpet
by
Jim Ginas
Is there spray or any type of material that goes on the sub-floor that would provide an insulating effective? (We are getting new carpet and 2 rooms of current carpet pulled up to change to hardwood.) the 1st floor area is cold from what feels like a draft coming up from the crawlspace.

The wood should be insulation enough. But there is a spray foam that can be put in cracks to seal the are of letting in the cold. We took down a banister in the kitchen and you could see the ground below. Hubby sealed the entire kitchen before the installers got there with cabinets, etc. That is the warmest room in the house!

Before we laid our laminate floor that had pad attached over plywood subfloor, we rolled out roof tar paper (cheaper than anything for floors) we ran it up walls 1-2" to be covered by molding (so no drafts at edge of room) and then just overlapped pieces 2-3" as we were laying. It helped considerably in stopping any drafts and towards insulating floors. We are in a doublewide trailer so have the same effects as a crawl space with drafts.

What you are most likely missing is a vapor barrier on the ground underneath the home in the crawlspace and insulation that should be between the floor joists. After time the insulation can fall down or "disappear" causing the floor to be cold. I would also like to put my 2cents in worth about carpet pads. Go the extra and get the better pad! Your carpet will last longer and it is so much better to walk on. I have always used the better pad and my carpet (builders grade too) which was installed 5 1/2 years ago still is wearing great despite laying it while doing renovations on the house. Carpet is insulation so it will help.
