JM Expands Self-Adhering Offering with the Launch of JM Vapor Barrier SAR

Johns Manville has expanded its self-adhering portfolio once again with the launch of a new fiberglass reinforced Vapor Barrier product. The new offering brings a two-part release film system and reduced packaging to the Vapor Barrier line.

This new material comes on the heels of the improved self-adhering formulation recently designed by the Johns Manville technical team. The new formulation brings extended shelf life, increased initial tack performance, and a higher softening point to enhance the track resistance of our products.

The Johns Manville team is focused on creating value for our customers and ensuring ease of installation for our contractors. These new products fill a gap in those offerings and ensure that we are providing the same performance our partners have come to rely on with our existing Vapor Barrier line while also incorporating product enhancement to aid in the quick and easy installation of these products. These sheets will also exhibit improved lay flat performance and workability for edge details.

This product will be manufactured in our Plattsburgh, NY facility and will be stocked throughout the JM network.
