NW Aluminum 640 Performance

The Next Generation Folding Glass Wall

Performance When Closed Matters Most

Large openings are easy to design and there are many options to choose from. When selecting a product that best fits your project, how it performs when closed is important.

All Climate Performance

NanaWall products are NFRC rated and certified for true energy efficiency in all climates.

Certified Testing Standards

NanaWall products endure the latest AAMA testing standards for air, water, structural, and forced entry.

Sustainable Design

NanaWall products contribute to multiple LEED rating systems and potentially several credit categories.

Notes
³ U-Factor, SHGC & VT for NW Aluminum 640 system unhinged panels will be about the same except in some cases variations of +/- .01 from what is shown.
⁴ NFRC simulated U factors of units with a horizontal mullion will have values of about .01 to .02 higher than units with no horizontal mullion. Please contact NanaWall for details.						⁵ SHGC = Solar Heat Gain Coefficient ⁶ VT = Visible Transmittance
* 2015 Energy Star Qualification Criteria: U-Factor for doors in all climate zones ≤.30, SHGC ≤.25 in South/South Central zones and ≤.40 in North/North Central zones. (For guidance only. NanaWall is not a participant of the Energy Star program.)
** Meets SHGC Energy Star Qualification criteria for North/North Central zones only.
Shown above are thermal values for select glass options only. Thermal values for many other glass options are available. These may be able to meet specific requirements, such as Energy Star values for other zones, CA Title 24 prescriptive values, other state and local energy codes, etc. Thermal values for glass with other Low E coatings and Suntuitive dynamic glass are available.
