Thanks for the question Judy, and for dropping by.

I had the same situation in my home not to long ago and found that
using a radiant barrier between the concrete slab and the laminate
flooring works best.

This Prodex radiant barrier is only 1/4″ inch thick and acts as a moisture barrier,
thermal break, and a bit of cushion when walking on the floor.
It installs with just a utility knife and some foil tape. No adhesives required, as it
floats on the floor just like the flooring.

You can purchase the Prodex radiant barrier at Insulation4less.com.
Be sure to buy Prodex as it has a closed cell foam center rather
than the bubble wrap type.

Also, be sure to tape the seams with foil tape (buy at your local home center).
Remember, DO NOT overlap the seams, just butt them together so you have a
nice smooth surface to install the flooring over.
Once you have the product in hand, how-to butt the seams will make perfect sense.

Also be sure to clean the floor well, prior to installation.

I hope this answers your question.
Thanks again.

Navedave,
Spray foam is a very effective insulator but I would not recommend using it in areas where you would be covering up plumbing. Once applied the foam is difficult and time consuming to remove.

I would recommend treating the crawl space for termites prior to insulating. Then to reduce moisture problems install a good quality vapor barrier on the ground.

I recommend using a radiant barrier installed on the underside of the floor covered by faced fiberglass insulation. This will give you an excellent R-value and easy access to any plumbing etc. in the future.

Quick DIY Tip; After installing the fiberglass insulation, use a permanent marker to make notes (on the fiberglass facing) of any plumbing or other utilities that are in the specific bays.

Thanks for your questions.
I’m here to help you.

Is there a problem with spray foaming the underside of your crawlspace? Like if leaks happen or moisture getting trapped, or termites living above the foam. What is your thoughts on how the spray foam would work on a residential level?

Thanks for the tips. Will definitely come in handy with cold weather coming in. I’m specifically interested in installing a radiant barrier.
