NW Reinforced 647 is designed for mid-rise buildings where higher wind load requirements and limit to deflection are needed. Designed to meet the structural capabilities required for taller buildings with a DP rating of +/-70 psf in accordance with (ASD) Allowable Stress Design Pressure, the reinforced frame profile is styled in a crisp, angular design where the intersection of two folding panels is a mere 5 ¼” (133 mm). As a performance-driven architectural solution, this system is independently certified and rated to meet CW-PG35.
