Casement Door Set

A casement door set is a hinged door system where the door panel, or "sash," is attached to the frame by hinges on the side and swings open either inward or outward. They are a popular choice for connecting interior spaces to balconies, patios, gardens, or terraces, offering a clean, contemporary aesthetic combined with high functionality.

Key Components of a Casement Door Set

A complete casement door set consists of several essential parts that ensure its security, durability, and smooth operation:

• Frame (Jamb): This is the fixed structure that surrounds the door opening. It provides stability and support for the entire unit. Modern frames are often made from durable, low-maintenance materials like Aluminum, uPVC (unplasticized polyvinyl chloride), or wood.
• Door Panel (Sash/Slab): This is the moveable part of the door that opens and closes. In casement doors, it often features a large glass pane (glazing) to maximize natural light and views, with minimal framing (slim sightlines).
  • Single Panel: A single door hinged on one side, ideal for smaller openings.
  • Double Panel (French Casement Door): Two door panels hinged on opposite sides that meet in the center, creating a wide, unobstructed opening.
• Hardware: These components are crucial for function and security:
  • Hinges: Heavy-duty hinges, often multi-point or adjustable, attach the door panel to the frame and allow it to swing open
  • Locking Mechanism: Typically a multi-point locking system, which secures the door at several points along the frame (top, bottom, and center) when the handle is engaged. This significantly enhances security.
  • Handle/Crank: The mechanism used to operate the lock and open or close the door.
• Sealing Mechanism: This includes weather-stripping and a tight compression design that ensures an air and watertight seal when the door is closed, providing excellent energy efficiency.
• Threshold/Sill: The bottom component of the door frame. Exterior doors often have a sloped threshold to shed water. A "no-threshold" design offers a seamless, trip-hazard-free transition, popular for accessibility.
• Glazing: The glass panels, often double- or triple-glazed with tempered or laminated glass, provide insulation, noise reduction, and safety.
