HVAC Insulation


Our Johns Manville SuperSeal® product is just one more way we demonstrate to you that, in every detail, materials matter. SuperSeal is a derivative of our proprietary Permacote coating used in the factory application of airstream surface and edge coating for JM HVAC products. The products are designed to be air drying and may be brush or spray applied. SuperSeal provides superior product protection against microbial growth. Applications include factory and field repair or the coating of factory-cut surfaces.

They are available for the following products:
• Linacoustic® RC
• Permacote® Linacoustic® HP
• LinaTex®
• Permacote® Linacoustic® R-300
• Spiracoustic Plus®
• SuperDuct® RC

Our accessories products provide installing contractors with the confidence that technical requirements will be met and system integrity will be maintained.
