Andersen 100 Series patio doors fit nicely in tight spaces. The operable panel on this door glides horizontally and won't interfere with your room or patio.
Andersen offers several color and hardware options allowing you to create a door that works well with your interior design.
This patio door is made with Andersen's own Fibrex® composite material, a sustainably manufactured, durable, and energy-efficient material. This gliding patio door has one panel that glides horizontally and one fixed panel. Gliding doors are a good choice in tight spaces because they don't swing out to take more space from your room or patio. Additionally, the 2-panel configuration allows more light to enter and brighten your space.

Permanent grilles on the exterior provide architectural style and detail to the window while grilles between-the-glass allow easy interior side cleaning.
Grilles applied to the interior and exterior of the window with aluminum spacers between the glass create an authentic look.
Style your window with permanent exterior grilles and choose between permanent or removable interior grilles.
SmartSun™ glass gives you the benefits of Low-E glass, plus it helps shield your home from the sun's heat by filtering out harmful UV rays.
Ideal for: All Climates
SmartSun™ with HeatLock Coating is available on 100 Series products. This prevents more heat from escaping your home but slightly reduces the visible light transmitted through the glass.
Low-E Glass reflects heat in the summer and helps to retain interior heat in the winter.
Ideal for: All Climates
Low-E4® with HeatLock Coating is available on 100 Series products. This improves the U-Factor performance of the window but slightly reduces how much light comes through the glass.
Sun glass has excellent thermal performance. This glass has a subtle tint that blocks out more heat from the sun.
Ideal for: Southern Climates
Clear dual-pane glass, which offers basic thermal performance, is in situations where codes allow its use. In Texas, clear-dual pane glass does not meet energy code.
See local code official for requirements in your area.
