According to the U.S. EPA, buildings account for an estimated 36 percent of total energy use and 30 percent of greenhouse gas emissions. Energy efficient XPS foam insulation products provide 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.
