NanaWall’s New Folding Glass System Separates Wood and Metal

NanaWall WA67 folding glass wall system

NanaWall’s WA67 folding glass wall system adds a spacer between the aluminum cladding and wood interior for added durability.

The addition of the spacer keeps the frame’s extruded aluminum from directly contacting the solid wood core, allowing each material to expand and contract without cracking or interfering with the other. The connection uses a “back-ventilated rain screen principle to protect and isolate the cross-grained solid, triple-laminated wood on the inside,” the company says.

“With the heat and humidity we get in the South, clad systems where the aluminum and wood touch or are glued together can cause warping since wood and aluminum expand and contract at different rates,” says Kenny Cobb, owner of Architectural Openings. “ “The WA67’s space between the two materials creates an evaporation chamber for the excess moisture to escape and allows the wood to regain equilibrium naturally, so the product lasts much longer than any other wood/clad glass wall.”

NanaWall claims that WA67 is the only product on the market to feature this kind of spacer design. 

The WA67 glass wall system can be inward- or outward-opening and top hung or floor supported. It can also be upgraded to feature triple-seals, triple-paned glass and deeper door panels for weather performance that reaches a U-value of 0.18 and a solar heat gain coefficient of 0.20
