Marvin Elevate Fiberglass Windows

Bay Window

The Elevate® Bay window is a group of three connected windows that extend out at an angle, allowing panoramic light and views. Style meets durability with a low-maintenance Ultrex® fiberglass exterior and warm wood interior.


Standard Features

  • Wood interior and fiberglass exterior.
  • Up to three windows connected at an angle to add space and light to a room.
  • Advanced Low-E Insulating Double-Pane Glass with Argon Features insulating glass with a Low-E coating that has two layers of thermal protection. Argon is inserted in the space between the insulating glass to make your home even more energy efficient.
  • Choose a combination of Elevate Casement and Elevate Double Hung in operable or stationary configurations.
  • Includes a window seat and head board.
  • Classic low-profile durable hardware offer clean aesthetics, safety, and security.


LowE 2 Features a double layer of silver on an inside surface of IG glass. It provides year round performance and comfort. This coating option provides better protection against radiant heat transfer than single layer metallic Low E coatings. Argon gas slows the movement of warm and cool air in IG airspaces and improve thermal performance.


TEMPERATURES MAY FLUCTUATE, BUT ULTREX® FIBERGLASS WON’T. Ultrex expands and contracts at virtually the same rate as glass, so it works with glass rather than against it. This means seals aren’t as prone to leaking, and windows aren’t subjected to sagging issues like other composites.


STRENGTH AND STABILITY OF ULTREX Ultrex pultruded fiberglass has superior tensile strength.   Windows and doors made with Ultrex bend and flex less, resist cracking and separating, and stand up better to everyday wear and tear. The exceptional strength and stability of Ultrex eases installation and establishes a secure, long-lasting fit that stays square and true year after year.


INDUSTRY’S BEST FIBERGLASS FINISH FOR LASTING BEAUTY Ultrex is the first and only fiberglass finish to be verified to AAMA’s 624 voluntary finish specifications for fiber-reinforced thermoset profiles (fiberglass). Windows and doors made with Ultrex resist scratches, dings, and marring more than vinyl. Our proprietary, mechanically bonded acrylic finish is up to three times thicker than painted competitive finishes, and it resists UV degradation even on dark colors.


Screens for the Essential product line feature a durable, low maintenance aluminum surround and Marvin Bright View™ mesh – a fiberglass screen mesh that provides improved airflow and more natural light while keeping insects out. Bright View repels water and resists dirt and grime for a sharp, vivid view.
