IKO Ener-Air insulation board is a lightweight insulation made at a state-of-the-art ISO 9001-2008 registered manufacturing facility. A coated glass fiber facer is laminated onto the board top and bottom, making it breathable.KO Ener-Air offers a thermal resistance of approximately 6 per inch to improve the energy-efficiency of walls and ceilings. 

IKO Enerfoil insulation board is a lightweight insulation, made at a state-of-the-art ISO 9001-2008 registered manufacturing facility. A foil facer is laminated onto the board top and bottom, making it non-breathable. IKO Enerfoil offers a thermal resistance of R6.2 per inch to improve the energy-efficiency of walls. 

OX Insulated Sheathing starts with a non-reflective resilient exterior facer that provides water resistance and high durability. The closed-cell, moisture-resistant polyisocyanurate foam core provides high compressive strength, a long-term R-value and a continuous air barrier. And a thin, high-pressure laminated member provides even more structural support. Put it all together and you get the highest possible performance from your structural sheathing.
