Casement Windows

Hinged side-out, sealed tight.

When the prevailing Gulf breeze matters, casements outperform — opening 100% of the sash area and pressing tightly against the frame when shut.

Why this window

The case for casement.

Casement windows pivot outward on a side hinge, opening fully to capture cross-breezes and seal tightly when closed — one of the most energy-efficient styles available.

Best For

  • Above kitchen sinks
  • Hard-to-reach openings
  • Modern & transitional homes
  • 01

    Best-in-class seal

    The sash compresses against the weatherstripping when closed, delivering one of the tightest seals in residential glazing.

  • 02

    Unobstructed views

    A single uninterrupted pane keeps sightlines clean — perfect for framing yard or pool views.

  • 03

    Effortless operation

    A folding crank handle opens the window with one hand, even above kitchen sinks or counters.

How it opens

See the casement in motion.

A folding crank swings the sash outward on its side hinge — opening like a door to a full 90°, the way an "L" pushes out from the frame.

Closed & sealedThe sash presses tight against the frame for one of the best seals available.
