CI Max Foam Continuous Insulation
Johns Manville CI Max® Polyiso Foam Continuous Insulation is available in R-Values up to R-26 and provides a layer of insulation to reduce thermal bridging and improve energy efficiency. CI Max Continuous Insulation is designed for exposed interior applications and is approved for use without a thermal barrier. It is suitable for wall or ceiling applications in residential, commercial, agricultural and industrial buildings.
Advantages
Thermally Efficient: Effective resistance to heat transfer, with R-values up to R-26.
Vapor Barrier: Maintains a minimum thickness of one inch and qualifies as a Class I vapor retarder.
Lightweight: Easy to handle and may be cut with a utility knife or saw.
