When IKO Enerfoil® non-vapour-permeable polyisocyanurate insulation boards come together with AquaBarrier™ Tapes, or IKO Ener-Air vapour-permeable polyisocyanurate insulation boards come together with AquaBarrier VP Tapes, they create the IKO 2-IN-1 Insulated Weather-Resistive Barrier (WRB) system for exterior walls, eliminating the need for a housewrap. This innovative system eliminates the need for a separate air/vapor barrier membrane system and is designed to effectively control air and vapor on exterior walls, as well as act as an effective drainage plane. Additionally, this system reduces energy loss by diminishing thermal bridging via the formation of a continuous layer of insulation across the exterior face of the building.
Enerfoil and Ener-Air are nonstructural rigid polyisocyanurate insulation sheathing boards. Enerfoil has an aluminum foil facer, and Ener-Air has a coated glass fiber mat facer. These facers, respectively, are both on the front and back surfaces of the boards.
Enerfoil (non-vapor-permeable) and Ener-Air (vapor-permeable) insulations offer the following outstanding characteristics:
Save time and provide additional value. Designed to help busy design professionals, contractors and project managers save labour, time and material cost, IKO’s exclusive 2-IN-1 system is a polyiso insulated sheathing and WRB system in one product, manufactured in Canada, meeting both ASTM E2357 and CAN/ULC S742 Standards for Air Barrier Assemblies specification.
Provide high thermal resistance and versatility. Polyiso has the highest R-value per inch of any rigid foam board insulation. Increased thermal resistance improves wall energy efficiency performance. Enerfoil foil facers provide long-term moisture resistance for wall applications, while Ener-Air glass fiber facers provide boards with the ability to “breathe” when necessary.
Effective strategy to reduce initial construction costs. The higher thermal values per inch of both Enerfoil and Ener-Air insulation sheathing products mean that they require less space than less efficient insulation systems to deliver the same level of performance.
Stud and fastener line indicators. Enerfoil and Ener-Air both have fastener line indicators to improve the accuracy of installation, while laminated facers on both sheathing sides provide moderate job site damage resistance.
Have a uniform thickness. Enerfoil and Ener-Air consistently maintain air space requirements in cavity wall applications and are ideally suitable for stucco and Exterior Insulation and Finish System (EIFS) applications. Boards are available in both 4' x 8' and 4' x 9' sizes (additional sizes are available using the IKO AccuCutTM service with in-stock thicknesses of 0.5" up to 2" for Ener-Air and 0.5" up to 4" for Enerfoil).
