What is a Fixed Casement Window?

The “casement” in the name refers to the frame’s profile. These windows are designed with a thicker frame (often called a “high profile”) to match the exact aesthetic of operable casement or awning windows. This allows you to mix and match fixed and opening windows throughout your home while maintaining a consistent, symmetrical look from the curb.

Why Choose Fixed Windows

They maximize natural light and views while delivering superior energy efficiency and zero maintenance.

Maximum Natural Light

Designed without moving parts, fixed casement windows offer expansive glass areas that flood interiors with daylight.

Superior Energy Efficiency

With no operable sash, these windows create an airtight seal, reducing drafts and improving insulation performance.

Unobstructed Views

Slim frames and large glass panels provide clear, panoramic outdoor views—perfect for scenic locations.

Modern Architectural Appeal

Their clean, minimalist design complements contemporary homes and commercial spaces.

Low Maintenance

Since they don’t open, there are no hinges or hardware to maintain—just simple glass cleaning.

Ideal for Large Openings

Fixed casement windows are excellent for filling wide or tall wall spaces where ventilation isn’t required but light and visibility are essential.

Where to Install Fixed Casement Windows

Living Rooms

Use them as a large central “picture” unit flanked by two operable casement windows.

Stairwells & Hallways

Perfect for adding natural light to transitional spaces where you’d never need to reach for a crank.

High-Vaulted Ceilings

Ideal for transom-style installations above doors or other windows where manual operation isn’t practical.

Feature Walls

Great for showcasing outdoor landscapes with uninterrupted glass and maximum daylight performance.
