Double Brick | Foilboard Insulation Systems

Double brick construction provides durability and thermal mass, but without insulation, it can allow unwanted heat transfer. Foilboard Insulation is designed for double brick applications, creating a continuous thermal barrier within the cavity to improve energy efficiency. By reflecting radiant heat, Foilboard helps keep interiors cooler in summer and warmer in winter while preventing moisture absorption and thermal bridging.
