The Only 50 Year Warp-free Guarantee and full structure warranty

As ornate and beautiful as sliding patio doors can be, then can present problems over time, or from season to season, simply based on the changes in climate, especially if they have a certain degree of wood, which most high end clientele seem to like to adorn their sliding patio doors with. The result is a patio door that is similar in appearance to a wooden French door with a large window lite glass opening.

If the opening to the patio is large (which is usually the case for more high end homes) the bigger the door and the thicker the glass. This creates a very heavy door which can present challenges for both the structure and the associated hardware to accommodate such large sliding patio doors.

Sliding door hardware can be expensive, and since we are most likely talking about large and heavy sliding patio doors, they will require heavy duty sliding door hardware, which can be very expensive, often times more expensive than the sliding patio door itself.

To exasperate things even more, unlike interior sliding doors, sliding patio doors are exterior sliding doors. That means on side of the door faces the structure’s interior while the other side faces the elements, which could be quite a contrast on either side of the door. This could potentially cause the sliding patio doors to fail due to warping as it attempts to acclimate to its environment(s). If the sliding door adjusts itself too much, the result may be a sliding patio door that does not seal correctly, or becomes inoperable due to movement.

Other framing treatments may be applied to the sliding patio doors, especially in extreme weather variation locations, like fiberglass sliding patio doors or even aluminum sliding patio doors, in an effort to reduce the inevitable door failure either seasonally or over time.
