Materials – Pella Impervia Sliding Patio Door
Pella Impervia sliding patio doors are made from Pella's patented five-layer, engineered Duracast® fiberglass composite.
- A fiberglass composite sharing the same properties of strength, durability and temperature resistance as materials used in the aerospace industry.
- Allows Pella Impervia products to withstand extreme conditions better than doors made from other materials.
- Highly stable material won't expand, warp or sag in summer heat, or shrink and turn brittle in harsh winter conditions.
Nine times stronger than vinyl and twice as strong as aluminum.*
|Very Good||Very Good||Fair|
Withstands heat up to 200F and cold down to -40F.
Low expansion and contraction rate assures consistent, weathertight seal between sash and frame.
Withstands impacts without deformation.
*In testing performed in accordance with ASTM testing standards, Pella's Duracast fiberglass composite has displayed superior performance in strength, ability to withstand extreme heat and cold, and resistance to dents and scratches.
- Unlike aluminum, which is a natural conductor, Duracast fiberglass composite offers excellent insulating properties and exceptional energy efficiency.
- The U-Factor of the Duracast frame is 2.4 times better than thermally broken aluminum.
- When compared to thermally broken aluminum, Duracast offers greater resistance to condensation and superior thermal comfort to those seated near windows.
- Unlike vinyl or aluminum, Duracast fiberglass composite offers low expansion and contraction rates that help ensure a consistent bond between sash and glass and a weathertight fit between sash and frame.
- Duracast withstands extreme heat (up to 200° F) without warping, sagging or softening – even in dark colors.
- Duracast withstands extreme cold (as low as -40° F), unlike vinyl, which becomes brittle in extreme cold.
Duracast fiberglass composite withstands major impacts without deformation, especially in cold weather.
Duracast features a low-maintenance, factory-applied powder-coat finish that resists chalking and fading – even in dark colors.
