Sustainable, Quadruple Laminated Wood

Unique to Generation 4 wood framed opening glass walls is quadruple laminated cross grained solid wood. This adds additional strength for larger panel sizes, structural integrity, and long-term durability. Additionally, NanaWall manufactures its moveable glass wall systems with sustainably harvested wood that meets the international standards of the Programme for the Endorsement of Forest Certification (PEFC). The wood is never veneered over inferior wood, allowing for sanding and refinishing when needed. Choose between Sapeli Mahagony, Pine, Meranti, Western Hemlock, and other additional wood finishes available upon request.

NW Wood 540

NW Wood 540 provides the slimmest wood frame in the folding door industry. With a quadruple cross-grained wood frame profile styled in a subtly rounded design, the intersection of the two folding panels is a mere 5 11/16” (144 mm). As a Generation 4 system, these wood framed opening glass walls can be customized with FourFold or SixFold panel sets that stack to the left, right, or center of the opening. Depending on glass type and glazing selection, NW Wood 540 offers thermal performance values as low as .19 U-Factor, making the system ideal for harsh weather climates.

These transparent panels diffuse natural light into interior spaces for bright, productive environments. As an interior system, NW Acoustical 545 can be paired with ADA-compliant, barely-there floor tracks for smooth transitions and clean aesthetics. The best part? Employees can have full control of their workspace, changing layouts on the fly with no effort.

NW Clad 740

The warmth of wood on the inside is enhanced by the durability and low maintenance of aluminum on the outside. NW Clad 740 provides the slimmest aluminum clad frame in the folding door industry with an intersection of two folding panels at a mere 5 13/16” (148 mm). Compared to others in the industry, NanaWall Clip-on Cladding Technology offers ventilation between the two materials, allowing them to expand and contract during temperature fluctuations. This permits moisture to dissipate, which is needed in environments where temperatures are extremely hot, humid, or cold. Depending on glass type selection, NW Clad 740 offers thermal performance values as low as a .21 U-Factor and features continuous weather seals for ultimate protection.

NanaWall Wood Legacy Systems

The first opening glass wall that NanaWall introduced into the market was wood framed. Since then, NanaWall’s wood framed product offerings have only expanded and improved. Compared to their Generation 4 counterparts, these moveable glass wall systems are triple laminated for enhanced durability. Let’s take a look at the legacy wood systems and what they have to offer.

The NanaWall WD65 features all the standard configuration options of a wood framed folding glass wall plus many specialty design options. The sculpted all-wood design features detailing around the frame and door panels to form a picture frame-like appearance. Additionally, all folding and locking hardware is integrated within the frame profiles for a clean look with no surface-mounted hinges just like in Generation 4 systems. All NanaWall wood framed opening glass walls have been independently tested for air and water penetration resistance, structural deflection, and forced entry with excellent results, including the WD65. Better yet, this system can be customized with specialty configurations like a Window Door Combination or FoldFlat® where the panels stack 180-degrees parallel to the opening.

HSW66 is the only wood framed sliding glass wall in the NanaWall product family and with it comes an array of other design possibilities, including unique shaped openings. The system is a completely top-hung design therefore the number of panels is only limited by the supporting structure in your design. Featuring an enhanced horizontal roller design and guide track, HSW66 allows each panel to glide around corners and posts for more flexible building options and to meet other design demands. This folding glass wall also features single-handed locking that is hidden inside the panel. The locking rod engages both top and bottom for added security and is rated to protect from forced entry.
