I would recommend this product for two reasons. They provide the standards that it is tested to and the results. I would never recommend anyone buy a radiant barrier without some indication that it has been tested to the relevant standards.
The other reason to buy this product is it is easy to work with. Cut's easily with a utility knife but will not tear from a cut edge. It's a pleasure to work with.

I found this product while researching "best methods for in floor heat". This is my first heated slab. We are in Montana and typically get 2wk+ of sub zero weather each winter. This floor system was the only working heat in our shop/house through the winter, as I completed the finish work. Without any air circulation, our building maintained T shirt comfortable temps. with both zones set at 63F.
Installed this foil myself with help from the concrete crew. This product lays tight to the contour of your gravel so you can achieve troughs for thickened edge/mono slabs. We taped the seams with HVAC foil tape and added an additional 1.5" of foam board on top of the foil. I left voids in the foam board and gravel bed for added strength under bearing walls. Resulting in apx 8" thick "mono beams" under the bearing walls. This product held up incredibly well through all of this extra traffic prior to the pour. I've not seen a drop of condensation anywhere on this slab even before the boiler was up and running. Great product! And the scraps work awesome for doghouse and chicken coop insulation.

Quick delivery. You guys are all over it.

Quality product Excellent customer service

I didn’t even realize it had shipped. Great company!

This Foil could block traffic from a convoy full of bandits heading for mexico southbound I-65 . The shipment was already here before I hung up the phone. Much appreciated

I needed to replace a 25 year old reflective barrier in my basement. The original was paper based and looked horrible, tearing easily, and not sealing. I decided to try EcoFoil's Solid Radiant Barrier Foil and I am so glad I did. This product is extremely strong (think rip-stop nylon), but thin, and easy to install. Highly recommend for a reflective vapor barrier.

3"x 180' Metalized Tape

It went down very nice. Easy to work with and seems to be very strong. I have yet to complete the project. It will be ready for this coming winter. That will be the test. Thanks 🙏

I’m waiting to install so no comments available except this. Why wouldn’t you offer the 3” pre-wrap required to reach R8 spec. You offer with other full wrap options. It should be a stand alone option or placed as a kit.

Great product and great service!

Quality product.

This is a quality product. The company was fast in getting it to me and was in great condition. I highly recommend Ecofoil and this product.
