Johns Manville® R-9.3 (16 PSI) Foil-Faced Polyiso Foam Board Insulation 1-1/2" x 4' x 8'

Johns Manville® R-9.3 (16 PSI) Foil-Faced Polyiso Foam Board Insulation

Product Overview The Johns Manville® R-9.3 (16 PSI) Foil-Faced Polyiso Foam Board Insulation is a top-tier insulation solution crafted to boost energy efficiency in both residential and commercial settings. Featuring an impressive R-value of 9.3, this board significantly enhances heat retention, thereby reducing energy costs. The foil-facing not only elevates thermal performance but also curtails air infiltration, making it perfectly suited for spaces measuring 1-1/2" x 4' x 8'. This rigid polyisocyanurate foam sheathing is designed to provide excellent heat, moisture, and air control, effectively safeguarding building exteriors and eradicating thermal bridges that cause heat loss. It adheres to strict building codes that mandate continuous exterior sheathing.
