Casement and Awning Windows





Series 900 Casement Windows and Series 925 Awning Windows combine the views of a picture window with the ventilation and ease of cleaning found in operating windows. Low-profile hardware and narrow sightlines give them a timeless elegance.

These beautiful windows are made from strong, durable, maintenance free aluminum, featuring our special polymer Thermal Barrier.

Separating the interior and exterior surfaces, the barrier dramatically reduces heat loss in the winter and heat gain in the summer.

We make our attractive and durable casement windows in rotary crank configurations as well as push-out awning and tilt-in hopper styles. They can be made to fit nearly any opening.



Standard Features

  • Sealed 7/8in. insulated glass for optimum thermal efficiency
  • Stainless steel commercial strength hinges
  • Unique "EZ-Clean" hinge system allows convenient cleaning from inside
  • Low profile "Fold-Away" handles minimize interference with curtains and blinds
  • Removable flush mount screens with your choice of aluminum or fiberglass mesh
  • Integral rubber gasket system seals out wind and water
  • Lifetime Limited Warranty when we install in your primary residence

Color Options

Our Thermal Barrier aluminum windows and sliding glass doors feature a durable, maintenance-free powder coat finish in your choice of five Standard colors (below, left). Custom colors and anodized finishes (below, right) are available for an additional charge*.
