IKO Ener-Air Wall Insulation is a rigid, polyisocyanurate foam insulation panel with high thermal properties. It is constructed from closed cell polyisocyanurate foam core bonded on each side to coated fiberglass facers during the manufacturing process. IKO Ener-Air is designed to be a non-structural sheathing in cavity wall, stud wall or cathedral ceiling construction. It is a dimensionally stable air barrier with a high water vapour permeance and excellent water shedding capabilities. The product is lightweight, easy to handle and can be sized with ease. IKO Ener-Air has a high thermal R-value of R6 per inch (RSI 1.05 per 25 mm), providing superior insulation protection, which helps to reduce energy costs and increase efficiency. IKO recommends taping the seams with IKO AquaBarrier VP Tapes.
