Henry® Company is a leading innovator of Building Envelope Systems® and understands the systems involved to ensure superior building performance.

JM Ice and Water Guard™ is a self-adhering membrane composed of rubberized asphalt roofing sheet with a strong inorganic glass mat for reinforcement. SureGrip™ is used under shingles, slate, shakes and tiles. It prevents leaks and damage to decking and internal structures from wind blown rain and water backup due to ice dams. SureGrip™ is also used as a vapor barrier for roofs, walls and floors.

An important consideration in the construction of industrial buildings, commercial or retail properties, and private residences, is selecting correct and effective waterproofing and weather barriers for the structure. Meeting the challenge to develop products designed for these tasks is MFM Building Products Corporation. MFM has focused on developing, testing, and producing specialty sealing and weatherization materials for over 40 years.
