Permacast™ Zero-Perm Coatings

The Factory-Applied Vapor Barrier for Fittings and for Penetrations Reduces Field Construction Costs, and Ensures Long-term Performance

Pipe Insulation PermaCast

PermaTherm advocates the use of our proprietary PermaCastTM coating (0.02 perm), factory-applied over fittings such as elbows, tees, etc. PermaCast vapor barriers significantly reduce field construction costs by eliminating the time-consuming application of layers of mastic and mesh around fittings, waiting for dry-time, and then fabricating a transition to the straight pipe insulation run.

Additionally, PermaCast coatings are used over insulation systems where the systems penetrate walls and ceilings.
