Extruded polystyrene (XPS) closed-cell, rigid XPS insulation significantly improves the energy efficiency of unfinished exterior and interior walls for remodeling and new construction. In addition, the XPS boards provide thermal resistance with an R-value of 4.6 to 5.0, depending on their density, to create a comfortable indoor temperature and reduce utility bills. Moisture-resistant XPS panel insulation, with an absorption rate of 0.3 percent, resists moisture intrusion during and after application to help protect against damaging and unhealthy mold and rot.

Lightweight, versatile, and simple to install, extruded polystyrene sheets typically come in 8-foot and 5-foot lengths, ranging from 16 inches to 4 feet wide and ¾-inch to 4-inches wide. The sheets come unfaced, and are covered with a foil facing, or laminated with plastic. The facing adds water resistance, and the lamination offers strength, but neither affects the sheets’ R-value. XPS sheets come in an array of colors (typically blue, green, and pink), based on the manufacturer, not insulating quality.
Flexible XPS boards come in various compressive strengths, making them ideal for numerous applications in all areas of the building envelope:
Manufacturing XPS insulation involves combining polystyrene crystals with special additives and a gas blowing agent. Manufacturers feed the mixture into an extruding machine that blends and melts it into a thick liquid. The liquid then gets processed through a die, which expands it into foam, shapes, cools, and trims it into standard-sized rectangular or square boards, with surfaces according to the intended use.
Specially designed machines produce XPS boards in smooth, rough, and grooved surfaces.
Demanding applications, like below-grade installation, utilize smooth XPS panels. Smooth, closed-cell XPS panels protect against absorption and diffusion due to long-term water exposure.
Rough surfaces increase the adhesion of the facade plaster.
Grooves in the XPS panel enhance wall drainage and thermal insulation for foundations.
XPS insulation offers many benefits contributing to an eco-friendly, healthy, durable, and safe building envelope.
XPS closed cell insulation, with an R-value of 4.6 and 5.0, gives it a high thermal resistance value, making it extremely energy efficient, by saving energy in buildings and reducing CO2 emissions.
100-percent recyclable XPS allows manufacturers to melt and reform the thermoplastic polystyrene resin into new XPS foam insulation.
XPS insulation’s high compressive strength allows it to withstand a high pressure of >300 kPa, so it can withstand more than lbs ft2 (30,000 kilos m2) with a maximum deformation of 10 percent, making it ideal for challenging applications:
XPS insulation provides water and freeze-thaw resistance, to protect the insulation’s thermal performance from damaging rot and unhealthy mold. In addition, the high permeability of XPS insulation makes it ideal for bathrooms and other high-moisture rooms.
Lightweight XPS insulation allows for easy application without irritating the worker’s skin.
Applying XPS insulation boards involves gluing the lightweight sheets to the substrate, which is much simpler than batts, blown-in fibers, or spray foam insulation. It is important to only use the manufacturer’s recommended foam-safe adhesive. The wrong glue can melt the foam. In addition, butt the sheets snugly together and seal joints with a manufacturer-recommended adhesive seam tape.
To insulate the stud, joist, and rafter cavities, cut the sheets to fit snug in the cavities, inserting them flush with the framing. To prevent airflow that can diminish the R-value, fill gaps along the edges with expandable insulation foam, safe for use with XPS. You can increase the R-value in two-by-six and larger dimension framing by inserting an additional layer of rigid foam insulation.
You can simply cut thin XPS sheets (less than 2-inches) by holding the straight edge of a utility knife along the cut line, scoring it about 3/4-inch deep. After scoring, lay the sheet on a table scored side up with the cut about 1-inch off the table. Firmly hold the sheet down and snap along the line. Trim the rough edges with the utility knife
For thicker sheets (greater than 2-inch), you will need a handheld drywall saw, or a table saw.
Installing 2-inch EPS boards on exterior sheathing requires additional furring strips or other structural supports. In addition, 2-inch XPS does not supply the strength needed to support the weight of the siding. Therefore, Sto strongly recommends that you check with your local building authority to determine the required type of additional support before installing 2-inch XPS as exterior sheathing.
