Product details:

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 systems. 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.

R-Value Of Radiant Barriers

Rather than rating by R-value, all radiant barrier products are measured by their reflective and emissive properties. Once installed, EcoFoil CBF Under Slab insulation is 57% reflective, meaning the product reflects 57% of radiant heat back to its source. There are some companies out there posting big R-Value numbers for their radiant barriers, but those numbers are rating the entirety of the system—including the product, air gap, and other building materials. In reality, most radiant barriers by themselves have little to no R-Value. If you need to satisfy a building code of a specified R-Value, we recommend the use of a traditional insulation in conjunction with our radiant barrier in order to meet code. For more information on R-values, see our How It Works page or contact a member of our friendly service team via chat, by calling (888) 349-3645, or using the form here.

 

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.

Product showed up late on site.

The product came to days late and half of my job wasn’t able to use all the product. Very disappointing when trying to get updates from the company on where the product was and why it was not delivered on the date I was given. Very frustrating to buy product that can’t be used.

We strive provide customers timely updates on their orders and we thank you for bringing this to our attention.

QUIT YOUR STYRAFOAM HABIT!

Way easier to install with tight fits to corners and walls, conforms to the ground leaving no voids to cause concrete to crack, better heat reflective properties, at half the cost delivered to your doorstep, why would you ever use styrafoam again when EcoFoil is available?
