Foam Board / Continuous Insulation
Johns Manville Polyiso foam continuous insulation boards provide a layer of insulation to reduce thermal bridging and improve energy efficiency. Polyiso consists of a uniform closed-cell polyisocyanurate foam core and provides one of the highest R-values per inch of any rigid insulation.
Foam Board, Continuous Insulation
AP Foil-Faced Foam Continuous Insulation
Johns Manville AP™ Foil-Faced Polyiso Foam Sheathing boards are available in R-Values up to R-28 and offer a reflective foil facer on one side and a non-reflective facer on the other. AP Foil provides exceptional heat, moisture and air control and, when installed correctly, eliminates all major thermal bridges that cause heat loss. The rigid continuous insulation board allows for maximum wall and worksite efficieny.
Advantages
Thermally Efficient: Effective resistance to heat transfer, with R-values up to R-28.
Water-Resistive Barrier: Meets the ICC-ES AC71 acceptance criteria.
Vapor Barrier: Class I vapor retarder at one inch.
Air Barrier: Meets the Air Barrier Association of America boardstock criteria, when properly installed.
Lightweight: Easy to handle and may be cut with a utility knife or saw.
