The sill of the Andersen® Perma-Shield® gliding patio door has an anodized aluminum track with a stainless steel cap that resists stain, rust, and denting. A thermal barrier reduces conductive heat loss and checks condensation on the inside.
All basic exterior frame members are covered with a rigid vinyl (PVC) sheath, which maintains an attractive appearance while minimizing maintenance. Andersen Perma-Shield gliding patio doors are available in three neutral color options. Specify White, Sandtone or Terratone colon
Wood frame members are treated with a water-repellent preservative for long-lasting protection and performance. Gliding patio doors are shipped knocked down and require assembly.
A flexible PVC weather strip on the head and side jambs provides a positive seal between the frame and panels.
