Design Options


  • Exterior Finish

    Exterior Finish

    A strong alternative to vinyl, our Ultrex® pultruded fiberglass exterior finish is applied through a patented process to provide a superior, consistent finish. The American Architectural Manufacturers Association (AAMA) awards certifications to materials that pass numerous, rigorous tests. These tests simulate the harsh conditions that a finish will encounter throughout the life of the window or door. Passing these specification tests and achieving AAMA 624 verification gives independent verification that the Ultrex finish is best in class among fiberglass products.


    Built for durability and low-maintenance, our Ultrex finish is 3x thicker than competitive finishes, with a smooth consistency and strong finish that resists fading, chalking, peeling and cracking, even in the darkest colors. If a design change calls for a new color down the road, our material can be painted without voiding our warranty. Six colors are available in neutral and dark tones.

    Selected: 
    Ebony
    Gunmetal
    Bronze
    Pebble Gray
    Cashmere
