Profold® | Progressive Foam Technologies

Professional Grade Insulation for any Project

Profold Fan-Folded Underlayment

Nearly 25% of your home’s wall is made up of studs that typically are not insulated, so it’s like having one entire wall of your home with no insulation. Adding insulation to your home’s exterior under new siding can help your home meet U.S. Department of Energy (DOE) insulation recommendations, as well as state and local codes.

Profold goes beyond energy savings

Moisture Management

Profold is made with StayDry Technology®, a proprietary manufacturing process that makes the insulation 3x more breathable than comparable products. With a perm rating of up to 4.6, it helps protect the home from potential moisture damage, letting water vapor generated inside the home escape.

Proven Energy Efficiency

Continuous Insulation powered by GPS (Graphite Polystyrene) Foam. Holds its R-Value: After extreme environmental testing, held its R-value in conditions that involved both constant thermal gradient and cycling between large temperature and humidity variations.

Termite Resistant

GPS is protected from insect degradation with a specially formulated insect inhibitor that’s safe for humans and pets.

Stability and Durability

Profold is adaptable in size, thickness, shape and density, providing maximum flexibility and durability.

Fire Performance

Profold is formulated with specially modified materials that are manufactured with a flame retardant (ASTM E84/UL 723).
