JM Ice and Water Guard - SBS Roofing Systems
JM Ice and Water Guard is a self-adhering membrane.
Meets or exceeds the criteria of ASTM D 1970 and ICBO
JM Ice and Water Guard is a self-adhering membrane composed of a rubberized asphalt roofing sheet with a strong inorganic glass mat for reinforcement.
Fiber Glass Reinforcement Mat: Offers excellent dimensional stability and tensile strength and withstands differential movement. Because it has no thermal memory less time is needed to relax the sheet, allowing for ease of installation.
Surfacing: The top surface is embedded with fine inorganic granules. The back is covered with an easy-to remove plastic release film.
