Moisture Management

The average family of four generates 4–6 gallons of water daily. Adding insulation to a home tightens it to reduce energy loss, but can also create potential moisture problems if water is trapped in the wall.

Red Label 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, Red Label 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.
