Why Use Polypropylene-Faced Insulation?
Metal panels can radiate heat and may develop condensation when warm, moist interior air contacts a cold surface. Properly installed faced insulation adds a thermal layer and vapor retarder.
- Helps reduce condensation on metal panels
- Improves indoor comfort
- Helps lower heating and cooling demand
- Creates a cleaner, brighter interior appearance
- Helps dampen interior noise
- Durable, tear-resistant facing
Glass Mineral Wool with ECOSE Technology
Glass mineral wool contains recycled and naturally occurring materials. ECOSE Technology uses a plant-based binder chemistry in place of the phenol/formaldehyde binder traditionally used in many older fiberglass products.
