According to a recent press release by EPA's Energy Star arm—in 2003, ENERGY STAR helped Americans save enough energy to power 20 million homes, reducing emissions equivalent to that of 18 million cars..

Extruded polystyrene foam is the best insulation you can choose when it comes to resisting water moisture absorption. Without the need for a facer or laminate, XPS products only absorb 0.3% by weight.

With growing concerns about the threat of global climate change, it’s important to look at various sustainable materials to see how they interact with the environment.


Did you know?


Extruded polystyrene foam insulation (XPS) and molded bead expanded polystyrene insulation (EPS) are similar, but have a lot of differences as well. XPS is the superior product when considering R-Value, moisture resistance, thermal performance, and compressive strength. Furthermore, the long term below-grade insulation performance study published by the molded bead EPS industry is not well-supported and is inconsistent with previous significant research in this field.
