Foil-faced Polyiso Rigid Insulation

Energy Shield® is promoted by its manufacturer as the most cost effective, energy efficient foil-faced polyiso rigid insulation sheathing material available in the marketplace. The product offers R-values ranging from 3.0 to 21.7, depending on thickness. Energy Shield® offers several “green” qualities, including zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP) due to Atlas Blowing Agent Technology. When properly installed, Energy Shield® foil-faced polyiso rigid wall insulation will provide added insulation and yield immediate energy savings in both Commercial and Residential applications.

Energy Shield® is manufactured with trilaminate facers (foil-kraft-foil) on the top side and a trilaminate or solid foil facer on the unprinted back side.

Use code accepted shear or corner bracing, such as 1" x 4" metal strapping or “let-in wood”. Energy Shield® insulating sheathing should be placed with the longest edge in a vertical position with edges on stud centers. Stud wall spacing of 16" o.c. does not require horizontal support; however, 24" o.c. stud spacing should have a horizontal 2" x 4" at mid-height for internal support. Nailing should be done with 3/8" diameter head galvanized roofing nails long enough to penetrate the wood stud at least 1 1/4". Do not allow the nail head to penetrate the sheathing surface. Fasteners should be placed no closer than 3/8" to the perimeter edges of Energy Shield® spaced 12" o.c. around the perimeters (including top plate and sole plate), and spaced 12" o.c. in the field of the board. When nailing siding materials over Energy Shield® care should be taken to avoid crushing the sheathing.
