Best-selling Features: Interest has been growing in this product since builders and architects first saw the 3D modeled frame parts, says Mathews Brothers. The sash members set into a 4 9/16-inch frame lend the look and feel of wood. Thermal performance and range of U-factors also contribute to its popularity.
