Energy efficiency is defined as a cost-effective way to reduce energy consumption through existing and improved building products technologies as well as through sound energy use.
Heating and cooling residences, commercial structures and other types of buildings takes a lot of energy. According to the U.S. EPA, buildings account for an estimated 36 percent of total energy use, and 30 percent of greenhouse emissions. Much of that use and resulting emissions is due to the need for internal temperature control. Without energy-efficient foam insulation, buildings could not achieve advanced energy efficiency and climate change reduction goals.
XPS foam is a superior choice for energy efficiency. With a long-term R-value from 3 (for 1/2”-thick sheathing boards) to 5 (for 1”-thick boards), and higher for thicker foam insulation, XPS sheathing boards increase the R-value of the entire wall. XPS insulating sheathing boards cover wood studs and other un-insulated parts of the wall, such as framing, ducts, wiring, and plumbing—which account for over 25 percent of the exterior walls in an average home. When properly installed, XPS forms a complete air barrier that reduces convection currents and air infiltration (draftiness), the leading cause of energy loss.
The Extruded Polystyrene Foam Association (XPSA) is a trade association representing manufacturers of Extruded Polystyrene Foam (XPS) insulation products and the industry's raw material suppliers. XPSA members collectively manufacture more than 95% of all XPS destined for use in the North American market. XPSA promotes the benefits that accrue to society from appropriate use of XPS foam insulation applications.
