New Historic Window on the Block

Combining the best of two worlds with historically inspired profiles, narrow sightlines, enhanced energy-efficiency and performance, EFCO introduces the 590X Steel Replica Window. Imitating the look of a classic, industrial steel window in a choice of three standard profiles—bevel, cove and T-grid—or in made-to-order options, project teams can also customize muntins to easily and economically match existing sightlines. The operable window delivers a thermal U-factor as low as 0.42 with a standard low-E product and a condensation resistance factor as high as 71. The window meets AAMA 513 standards for accessibility, and the inclusion of thicker glass enhances acoustic performance for quieter interiors.
