Originality, sturdiness and durability This door, called the Diamond, deserves its name: this innovative door is the most air and watertight in North America. It combines the Martin team’s know-how with the originality, solidity and durability that you expect.



Its unmatched air and water tightness is achieved by a multi-point lock anchored in 5 places as well as double weatherstripping.

This folding door is offered up to 16 feet wide with 7 panels. As with our other doors, it is equipped with 2 1/4 inches thick wood panels and a sill with a double drainage system. Opening the panels is effortless since they rest on the sill.

Obviously, this door’s security is a credit to the Martin collection. Optionally, we can offer an innovative retractable screen. Hardware is available in 3 colours: dark brown (standard), silver (option) or white (option).


  • Solid 6 5⁄8 inches finger-jointed pine frame assembled with screws.
  • 1 1/16 inches thick frame.
  • Secondary frame 2 1/4 inches thick serving as support to the panels.
  • The anodized aluminum head guide is available in dark brown (standard), silver (optional) or white (optional).
  • Compression weatherstripping system (tan coloured).
  • 2 1/4 inches thick, laminated solid Ponderosa clear pine door panels with a protective sealant.
  • Panels assembled and strengthened with 5/8 X 4 inches dowels.
  • Peripheral weatherstripping ensures optimal airtightness for heat and soundproofing, all the while preventing air and water infiltration.
  • Depending on the configuration, both the casement panel and tilt-turn options are easy to use, since they exist independently from the foldable panels.
  • Our standard: tempered double glazing at 1 inch (25 mm) thick with Low-E window film, argon gas and a high-performance warm edge spacer.
  • Optional: tempered triple glazing at 1 1/4 inches (32 mm) thick with the same characteristics as previously mentioned for the tempered double glazing.
  • Multi-point locking system with a handle that controls the lock to the sill, frame and head. Depending on the configuration, the handle can be installed on the main panel, the casement or the tilt and turn window. Available colours: dark brown (standard), silver (optional) or white (optional).
  • The panels’ weight is fully supported by the rail system on the ground, ensuring smooth, gentle gliding.
  • Adjustable hinges and trucks allowing to adjust the door panels.
  • High-performance champagne-coloured doorsill with a unique design and with PVC thermal break.
