Series 600 Aluminum Multi-Slide Door

The choice of builders for over a decade, the Volume Program’s Series 600 Aluminum Multi-Slide Door features moving walls of glass that stack or slide into pockets for extra wide openings that eliminate the barrier between indoors and out. Thermally broken aluminum and dual-paned low-E glass make the Series 600 energy efficient. Sealed stainless steel ball bearing rollers make it easy to operate, even with large panel sizes. And a 90-degree alternative eliminates a connecting post for uninterrupted indoor-outdoor living. 

  • Clean design with 2.5″ sightlines, wide panels, and expanded glass
  • AAMA- and NFRC-tested and certified
  • Premium hardware and roller options
  • Low-E, dual-paned, argon-filled glass from Cardinal IG
  • A .39 U-factor for energy efficiency, may vary based on configuration and glass options

Installation Methods

The methods for installing our multi-slide door are designed to meet the needs of our Volume Program partners and may vary by market. The most common approach for installation consists of a deep stud wall that usually includes a 2×6 stud framing member with either a 2×4 or 2×6 framing member furred on the interior. On this larger wall profile, builders can center our track and allow the drywall and stucco to be wrapped to the door frame. An optional stucco return kit is available in either a 1″ or 1 ⅜” for builders that prefer this installation.

Sill Options

Water Barrier Sill

Designed for effectiveness in all climates, the water barrier sill’s 1.5″ interior leg and weep-hole system safeguards against water intrusion. For additional protection, the back leg of each sliding panel extends into the track to help keep out dust and debris.

Flush Sill

When ease of entry is more important than performance against the elements, our flush sill is the perfect choice. With an interior and exterior sill height of just .75″, it lines up with most interior flooring for a smooth transition to the outside. Weep holes in the track allow water to drain away from the door while the back leg of each sliding panel discourages dust and debris by extending into the track.

Note: The flush sill may be less effective at preventing water penetration than the water barrier sill and therefore may not be appropriate in all climates, conditions, and exposures.

Handles and Locking

Flush-Mounted Handle

The standard option for all Western Window Systems’ multi-slide doors, the flush-mounted handle’s clean, narrow design allows panels to easily slide past each other or into a pocket. An optional keyed lock allows the door to be unlocked from the exterior. Finish choices are available in brushed nickel or black.

Premium Handle

Our premium handle features a minimal one-piece design, comfortable grip, and the option of a keyed lock that allows the door to be unlocked from the exterior. Finish choices are available in brushed nickel or black. The premium handle is not available on pocketing multi-slide or 90-degree door systems.

Finish Options

Warmtone and White are a polyester hybrid painted finish, meaning the finishing process for the organic coatings conforms to a minimum rating of AAMA-2604. Bronze Anodized and Satin Anodized finishes have a Class 1 rating, the highest and most durable rating for anodized aluminum products.

Screen Options

Exclusively designed for our three- and four-panel multi-slide doors, the retractable screen collapses easily and stacks to the side of the door when not in use. Providing optimal ventilation and flexibility, it expands to the full width of the opening using tensioning cords and precision bearings that provide stability, keep operating force low, and extend product life. Available on door sizes up to 16 feet wide. Screens are mounted on the interior of the door.
