Sheathing is one of the most basic and widely used applications for EPS insulation in residential and commercial construction. It helps create an envelope around the structure, covering wall cavities and studs to increase their resistance to heat transfer and moisture protection.
With its versatility, ease of installation and consistent performance benefits, EPS foam insulating sheathing has become an industry standard. The sheathing is non-structural, and is primarily used as an exterior insulator, both below and above grade, although it can be used throughout the structure in roof, floors and ceilings. Different densities help provide the R-value required to meet local building energy codes.
EPS sheathing is used in renovations as well as new construction because of its compatibility with wood and steel framing, and masonry. Manufacturers can provide the builder with insulation of varying densities, which translates into a structure meeting or exceeding energy code standards without the added expense of increased stud widths.
