Earth-Barrier provides proven resistance to the transfer of heat and cold energy by its unique material makeup. By incorporating unique recycled Expanded Polystyrene (EPS) foam as the core component, the material effectively creates a foam cooler “igloo” effect. Basically, Earth-Barrier keeps the heat on one side and the cold on the other. 

A great analogy is the foam coffee cup. What happens when you hold a hot coffee cup or ice-cold beverage? Hopefully nothing. You can hold the hot or ice-cold cup in your hand without sensing the thermal effects of the contents. A normal foam cup is thin. Can you imagine how well it performs with a thickness of 6-16″ (3/8″)? It works extremely well, as laboratory testing has shown. What better product than Earth-Barrier is there to use to control the heat loss in your hydronically heated floor, slab on slab, slab on grade, or retrofit project?

The Earth-Barrier™ unique core material is Expanded Polystyrene (EPS) with a jobsite tough, heavy-duty poly film laminated on both sides. Also, adding to Earth-Barrier’s™ labor saving features, we added a 3″ flap of film running down the sixty-four-foot length of the insulation with an aggressive double-faced adhesive on the opposite side of the overlap, providing a seamless vapor barrier. This extra material allows one roll to be neatly secured up to the next roll. You will now have a seamless system that will not allow the transfer of heat or cold and will retard the transfer of all forms of moisture, increasing the overall energy efficiency of your home.
