Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material.

Is EPS the same as Styrofoam?

The foam that you formerly knew as styrofoam is actually expanded polystyrene foam or EPS. This material is made from polystyrene, a plastic that’s often used to make clear products like food packaging or lab equipment.

How long does EPS insulation last?

EPS is a durable, rot proof and permanent material when specified and installed correctly. It will remain effective for the life of any application with no deficiency effects to be expected over a 100-year life cycle.
