Why Choose Pella Impervia
Pella Impervia Fiberglass Windows and Patio Doors
Stronger Than the Competition
- Our proprietary fiberglass is a thermoset material, meaning it won't melt or breakdown when exposed to environmental temperature swings. Our fiver-layer fiberglass is the strongest material available for windows and patio doors, engineered for lasting durability.1
- The durable, powder-coat finish resists chalking, fading and scratching – even in dark colors - and keeps your sleek windows looking great for years.
- Fiberglass is naturally strong, but we made it stronger. Our durable fiberglass will never rot or corrode and is naturally resistant to water.
- Our proprietary five-layer fiberglass is tested from -40ºF to 180ºF and can handle the most extreme heat and cold.2 It will not warp in extreme heat or become brittle in extreme cold.
Sleek, Timeless Style
- Interior and exterior color options are available to achieve your unique design style, including Black. Choose a solid-color frame or pair a White interior with one of our five exterior colors. Our colors are a durable, powder-coat finish which resists chalking, fading and scratching.
- Select a contrasting or complementary hardware finish to add interest or even make a statement.
- Create bold designs from sleek profiles and more glass with our intentionally designed products made from our exceptionally strong proprietary fiberglass.
- The superior strength of Pella's fiberglass allows you to combine windows together to create larger, unique combinations, made just for your remodel or new construction project.
Proven Performance
- Pella Impervia products with dual-pane glass offer energy-efficient options that will meet or exceed ENERGY STAR® guidelines in all 50 states.3
- Pella Impervia products are designed to resist air and water infiltration.
- Our fiberglass has virtually the same expansion and contraction as the glass, almost none. This helps reduce the risk for air-seal failure and provides long-term stability for dependable operation.
- Whether new construction or window replacement, our exclusive installation methods help save time and reduce callbacks.
