Traditional French patio doors. Classic beauty and design.
Derived from an original French design known as the casement door, Andersen redefined the traditional French patio doors category in 1985 with the introduction of the revolutionary Frenchwood® patio doors. Traditional craftsmanship combines with modern energy efficient technology to create this modern classic. We've even added a french outswing patio door and a space saving sliding french patio door version to this traditional styling.
