In residential and commercial building applications, insulation is necessary to maintain temperature control. XPS foam insulation is a premier choice for building planners because it is highly energy efficient, resulting in significant savings in energy use—and in energy costs. Find out more...

Extruded polystyrene foam is the best insulation you can choose when it comes to resisting water moisture absorption. No other foam building insulation provides the same level of protection against water damage as XPS foam. Find out more...

According to the U.S. EPA, buildings account for an estimated 36 percent of total energy use, and 30 percent of greenhouse gas emissions. The use of energy-efficient XPS foam insulation products provides numerous environmental benefits, including major reduction in energy use and resulting greenhouse emissions. Life cycle analyses show XPS foam to be a sustainable choice. Find out more...


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. See here for more information.
