The RMax Thermasheath is a 4 ft by 8 ft rigid polyiso foam insulation board used for walls, roofs and ceilings. It offers high R-value per inch, typically around R-6, making it one of the most efficient insulations available. It suits homeowners and contractors insulating basements, exterior walls or attics where space is tight. Compared with XPS or EPS foam, polyiso delivers more R-value per inch but costs more and can absorb moisture if not sealed.
