If you are using radiant to heat, should use CreteHeat modular green panels as you get can 2" which gives you R 10 or 3" which gives you R 14! Snap shiplap joints together, walk tubing in place and pour! Already has the poly moisture/radon protection built in as well as the knobs to hold the...

Re: Crete Heat Pricing Crete-Heat the 2 inch will give you a more constant R value than other insulation which tends to "outgas". It has shiplapped joints providingfor a continuous thermal insulation, 10 mil polystyrene film vapor and radon barrier, has the 3" on center fasteners that allow...

thanks Walrus for the great link! FOIL does not belong under concrete! New study out there however does show radiant barrier drops attic temps by 23 degrees! That is where foil belongs!

The study about EPS foam retaining its R- value was in the Jan 09 issue of Concrete Monthly and was done by ACH Foam Technology and was a study done over a 15 year period to study the difference between EPS and XPS foam. From what I understand it basically found that EPS foam maintains 94% of...

Insulation under the slab should be about keeping the heat in the slab, keeping the moisture out of the slab, the radon out of the slab, and preventing cracks in the slab. Having a product that will help with all aspects is adventageous and one that also is a radiant tube grid holder is an...

Mark, as you are aware temp differencial is not only vital element to look at. Having a product that resists moisture, is radon resistant ,as well as thermal barrier all in one . If you want equal temp differencial please try the Barrier X5 which is 1 1/4 thick.

Kuddos Ezzie for helping to set the record straight on reflective foil under concrete! AS a major distributor of reflective foil we always are trying to educate people about NOT using foil underground and using the Barrier instead (see above) . We have studies to back this up if people are...

The Barrier, extruded expanded polystyrene is 100% waterproof and vapor proof, seamless and specifically designed for under concrete and radiant heating applications. It does not break when walked on, cost effective and is shipped direct to job site. can be seen on www.GreenInsulationProducts.com

The superior way to insulate under concrete is with the BARRIER. It is a product made for this application. It comes in a roll with patented self sealing tape on both sides for 99% moisture control, vapor control, radon resistor, thermal control all in one product that will not break under...
