EcoFoil Under Slab Insulation is a patented breakthrough product in the concrete slab insulation industry. It is specifically designed for use as a thermal barrier under concrete and works superbly with radiant heat system. EcoFoil Under Slab Insulation (1/4" to 5/16") thick, is manufactured with a single layer metalized reflective sheet laminated between two layers of strong polyethylene bubbles. EcoFoil Under Slab Insulation has a compression strength of 140 PSI. Our insulation is thin and lightweight, making it easy to conform to your grade and reduces any worry of leaving pockets or voids like traditional insulation.

Unlike traditional bubble insulation, where the foil is exposed, our patented product is encapsulated. This was done for two main reasons; the integrity of the foil and the airspace it creates for effectiveness. If the foil surface comes into direct contact with certain acidic soils it can corrode the reflective properties of the insulation. This can also happen during the curing process of concrete. For this reason, standard radiant barriers or bubble insulation are not an appropriate insulation for an underground application. It is also important to maintain an airspace on one side of the insulation in order for it to be reflective. By laminating the reflective metalized sheet in between two layers of our sturdy bubble insulation we have ensured the integrity of the foil by protecting it from corrosion and deterioration. We are also maintaining an air space by placing the foil in between the bubble layers.

Most importantly, EcoFoil Under Slab Insulation reflects 57% of radiant heat back up towards the surface, whereas without under concrete insulation, this heat would travel down and be lost in the soil. Additional benefits are that EcoFoil Under Slab Insulation provides a vapor and radon barrier.

Important - The seams of EcoFoil Under Slab Insulation must be taped together so when finished the insulation acts like one sheet. We recommend our 3" White Seam Tape for this application. Just like the name implies, this insulation can be used under any concrete slab to reflect 57% of radiant heat.

Two birds one stone

Given the astronomical price of 6mil plasic, I decided to spend a little extra on this stuff as vapor barrier instead. I applied eco foil under 1.5" of ridgid foam as sub insulation for a heated mono slab. This stuff was easy to install and resisted alot of foot traffic as we layed foam and rebar down in sequence. We were working in extremely windy conditions, the rolls were small enough to pin down while another guy taped the seams. Once a couple rowns were down we put foam, then rebar to pin everything in place. Very happy with the ease of installation. Neither I nor my concrete guys had ever used this product before.

Great reflectivity, good insulation, rough and easy to install. The best radiant heat under-slab barrier I have installed.

Quick, Easy and As Described

My Underslab Insulation - 4’ x 125’ rolls as well as the recommended joint tape all arrived very quick. The foil bubble rolls were very easy to roll out and install. The recommended joint tape wasn’t quite as sticky as I would have liked. I will likely try a different tape next go around but will stick with EcoFoil for the insulation!
