Our German-engineered French doors are available in both single-sash entry and double-sash patio door configurations. They feature a 5-chamber profile system with a basic depth of 82 mm, which provides excellent thermal insulation thanks to a thermal break in the threshold area. The narrow face widths contribute to a sleek appearance, while the increased depth enhances security and resistance to break-ins. The doors are designed with three levels of drainage to offer optimal protection against wind, rain, and noise, with concealed drainage for a clean look. This makes them an excellent choice for coastal environments.
