IKO Ener-Air is a rigid, polyisocyanurate foam insulation with high thermal properties. It is constructed from closed cell polyisocyanurate foam core bonded on each side to coated glass fiber facers during the manufacturing process. IKO Ener-Air is designed to be non-structural sheathing in cavity wall, stud wall or cathedral ceiling construction. It is an air barrier with a high water vapour permeance and it has excellent water shedding capabilities. IKO Ener-Air Sheathing is dimensionally stable and can be sized with ease. It is also lightweight and easy to handle. It has a high thermal R-value that provides outstanding insulation protection, which helps to reduce costs. IKO Ener-Air Sheathing is available in a board size of 1220 mm x 2440 mm (4′ x 8′) and in a range of thicknesses from 19 mm to 51 mm (0.75″-2.0″).
