French doors, with a specialized hardware solution, are designed exclusively for the US market. They are available in configurations for single-sash, double-sash, outward-opening, and inward-opening doors. These designs cater to various preferences, offering flexibility and functionality.
Features:
Movable mullion – In double-sash doors, a movable mullion enables both sashes to open simultaneously, creating a wide and unobstructed passageway. This feature is particularly beneficial in spaces that require seamless transitions, such as terraces or garden exits. Unlike traditional European designs, where the passive sash is secured with angle bolts, this system utilizes a handle for operation. This design improvement not only simplifies usage but also enhances user experience by providing smoother and more intuitive functionality.
Innovative handle operation – The handle mechanism is designed for effortless and secure operation, offering users a unique experience. When pressed, the handle allows the sash to open and then automatically returns to its original position. In contrast, lifting the handle activates an additional locking tongue and engages the locking rollers within the frame strikers. This mechanism significantly increases the number of locking points, ensuring a tighter seal between the sash and the frame. Additionally, raising the handle enables door rotation through cylinders, enhancing overall versatility and making the system both practical and reliable.
Enhanced security and sealing – Security and durability are key aspects of this locking system. The mechanism includes two locking points on the top and bottom horizontal sections of the sash, effectively strengthening the connection between the sash and the frame. As a result, the door achieves superior sealing, which enhances thermal and acoustic insulation while preventing unwanted drafts or water infiltration. This advanced design ensures long-term reliability, contributing to improved security and weather resistance.
Material options and future expansion – Bertrand currently manufactures French doors using high-quality PVC and wood systems, offering customers a range of material choices suited to various architectural styles and preferences. Looking ahead, the company plans to expand its offerings to include aluminum systems, providing even greater flexibility and aesthetic options. This future expansion will allow customers to select the best material for their specific needs, whether prioritizing energy efficiency, durability, or modern design.
