Breathable Sheathing Ener-Air by IKO is a breathable rigid polyisocyanurate insulation sheathing with a coated glass fiber facer laminated on the top and bottom side. Manufactured at IKO's state-of-the-art ISO 9001-2008 registered facility, Ener-Air • Provides high thermal resistance of R6 per inch (RS11.05 per 25 mm) for improved energy efficient performance of walls. • Helps decrease the cost of construction. Designers can reduce the overall footprint of their buildings, as a smaller thickness of Ener-Air achieves the same R-value (RSI) as other thicker types of insulation. • Is environmentally friendly. No ozone-depleting HCFC's are used in the manufacture of Ener-Air, making it an ideal "Green" product. Ener-Air s Energy Star® certification means that it clearly contributes to reducing energy consumption. Can also contribute to points under LEED, EnerGuide and other energy efficiency rating programs. • Is user-friendly. Coated glass facers on both sides of the sheathing provide moderate abuse-resistance on the jobsite. Ener-Air is lightweight S easy to cut, thus reducing labor costs on site. • Provides versatility. Coated glass fiber facings provide the long-term moisture resistance necessary for cavity wall applications. Ener-Air s facings are also compatible with solvent-based materials, which can attack and compromise the performance of other thermoplastic insulations. • Has a uniform thickness for consistently maintaining air space reguirements in cavity wall applications. • Is available in 4' x 8' boards in a variety of thicknesses including 19mm (.75"), 25mm (1"), 38mm (1.5") and 51mm (2.0"). • Not only is Ener-Air a superior insulating product but doubles as an air barrier as well. When suitably detailed the Ener-Air system can be a code-compliant air barrier assembly. Thus fulfilling two jobs at once. Frame Construction Siding For wood framing, corner bracing is recommended at corners and around large openings. Ener-Air is fastened to the studs using washered nails. Ensure that the fastener penetrates a minimum of 3/4" (19 mm) into the framing. Steel stud walls have Ener-Air fastened to the studs using mechanical fasteners with metal washers. Sheathing is installed with fasteners spaced 12" (300 mm) o.c. in the flat, 8" (203 mm) o.c. around the perimeter. Consult your local Building Code for reguirements pertaining to air barriers, joint treatment and strapping. Frame Construction Brick Veneer For wood framing Ener-Air is fastened to the studs using washered nails. Ensure that the fastener penetrates a minimum of 3/4" (19 mm) into the framing. Steel stud walls have Ener-Air fastened to the studs using mechanical fasteners with metal washers. Sheathing is installed with fasteners spaced 12" (300 mm) o.c. in the flat, 8" (203 mm) o.c. around the perimeter. Approved masonry ties must be spaced and installed as per masonry reguirements. Install low expanding foam to create tight seal at small [<4 sg. in (100 sg. mm)] penetrations through the exterior envelope and irregularities at wall intersections. Maintain air space reguirements.
