Window Finishes

Our low-maintenance interior and exterior finishes resist fading, peeling, and chalking even under the most extreme coastal conditions. Finish options include five colored finishes and five wood grain finishes that will bring beauty and natural warmth to your home. 

Our Bronze, Black, Bronze, and Stone White Kynar finishes are AAMA 2605 certified. AAMA 2605 is the American Architectural Manufacturer's Association's high-performance exterior specification. Finishes meeting this certification exhibit outstanding resistance to humidity, color change, chalk, gloss loss, and chemicals.
