NanaWall Systems

May 19, 2019

The WA67 folding glass wall system from NanaWall Systems is the first to mount extruded aluminum cladding to a solid wood core with a spacer bar to secure the two materials. This and a proprietary evaporation chamber allow for various expansion rates between the materials to avoid cracking in any climate.

The extruded aluminum is attached to the wood using the back-ventilated, rain screen principle to protect and isolate the cross-grained solid, triple-laminated wood on the inside. An enhanced option features triple seals, triple-paned glass and deeper door panels for even higher weather performance that reaches U-value of .18 and a Solar Heat Gain Coefficient of .20 for optimum energy efficiency. Inward- or outward-opening door panels are also available for more design flexibility. The system can be top hung or floor supported and is life-cycle tested to open and close more than 20,000 times without failure.
