Aluma-Seal is a medium density, closed cell PVC foam that acts as a thermal insulator to prevent condensation build-up on surfaces to which it is applied.

Cast on an aluminum liner, the foam adheres to the aluminum, and then conforms to irregular surfaces to create a protective barrier. It also reduces vibration and deadens sound in HVAC applications. Aluma-Seal remains pliable at temperatures of -40°F to 172°F (-40°C to 78°C).

All Foam Seal Specialty PVC foams are sulfur free, low VOC, certified Prop 65 compliant, and resistant to UV, petroleum, & cleaning solutions.

We manufacture to your specifications. Aluma-Seal is available in 1/8” to 1/4” gauges, and has a shelf life of 6 months with adhesive and 2 years without adhesive when stored at or below 75°F.
