I am going to tear up the carpet and pads and install wood floors.
I was wondering if there is a thin roll type insulation maybe at Home Depot
or other that is only .25-.33 thick inch to add a couple of R value back
before I put the wood down. Removing the carpet is going to remove some insulation value so......
thanks

Hi 99, Thin and insulation are going in opposite directions:), but you could use the foam underlayment normally used with laminate wood floors. It should give you at least an r-1. The next up in thickness would probably be the pink stuff in the fan-fold, but not sure if it is acceptable to use under wood floors.

Cork underlayment offers insulative and sound reduction qualities beneath hardwood floors.

The thin underlayments aren't meant for "insulation" properties, just cushioning to lengthen the life of the flooring. If you can access under the floor, add insulation between the joisting. A layer of the cushioning, however, won't hurt, and will certainly help in air infiltration, should you have any.

SolidBlack-HD claims it has higher r-value than cork. SolidBlack–HD-TPO Underlayment for Wood & Laminate Floors - BALBOA FLOORING - San Diego (http://www.balboaflooring.com/index.php?pg=solid-sound)
