Product Overview

The Reflectix concrete slab insulation is an innovative, easy-to-handle product that increases the energy efficiency of radiant floor and snow melt systems (Under concrete). The foil, within the product, acts to spread out the heat signature of the heating coils. This results in a more comfortable floor due to a more even floor or slab surface temperature.

  • Reflectix 48 in. wide concrete slab insulation is easy to handle, install and transport
  • Insulation is a coated foil with a white poly surface
  • With taped seams, the product is a vapor or radon retarder
  • Not affected by moisture or humidity
  • Reduces or eliminates ground water intrusion into the slab
  • Foil is protected from lime in curing concrete
  • No nesting characteristics for insects
  • Will not compress, collapse or disintegrate
  • Durable and lightweight

Answer: 
Dear Robert: Reflectix has almost no insulation R value by itself. The R values claimed on the package are based on a sealed 'air gap' that you must create or build. Look for the Federal Trade Commission Fact Sheet on the Reflectix Inc. website for the details.
In your application there obviously will not be an air gap, so the R value would be near zero.
The best option would be Foamular XPS foam board Read More

The best option would be Foamular XPS foam board from Home Depot, which provides R5 per inch. XPS does not absorb water, unlike polyiso foam board, so it is perfect for concrete slabs and radiant heating. Versions are also available with high compressive strength under large slabs; you can order them via the Home Depot Customer Service / Pro desk.
I hope this is helpful.

February 1, 2016
Is it possible to use Reflectix (when remodeling kitchen) over very old existing concrete slab? I want to install over all room new porcelain tile and just in part of that kitchen I want to install radiant heat foil under the tile.
This concrete slab sits practically on the ground and definitely is not protected against moisture. If I could use Reflectix, how should I do it? Please?
Thank you.

Rated 4.0 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Exactly as advertised The insulation is a lot tougher than I expected it to be. It went down easy. Tough enough to walk on. October 5, 2016
Rated 4.0 out of 5.0 by Nice to work with I used this insulation under a concrete slab. It was easy to lay out and tape. Only problem was getting the inspectors to accept it. They didn't have any experience with it so I had to gather specs and comparison information. September 20, 2016
