This Leed® Gold development features Technoform's polyamide thermal barrier profiles.

Slate: 321 N.E. Couch St., Portland, OR 97232

Slate is a high energy-efficiency, 10 story building with retail, office, and apartment space featuring window, entrance and unitized curtainwall system by Wausau Window and Wall systems.  Wausau's aluminum-framed products have all been thermally improved using a polyamide barrier from Technoform. Combining the thermal barrier with solar-control, low-e, insulating glass achieves the specified performance for low solar heat gain coefficient, low U-Factor, high condensation resistance factor and high visible light transmittance. 

To match Portland's climate and the project's goals for energy efficiency and occupant comfort, Slate earned LEED® Gold certification through the U.S. Green Building Council in December 2016.
