Casement Windows

Overview

Incredibly smooth operation and exceptional performance.

Ultra-smooth operation and industry-leading performance have made this product one of our most popular offerings. These windows provide your home with meaningful ventilation, but close so tightly they create a seal in your building envelope that is equally meaningful. We also have an awning or casement for any design scenario; many of our awnings and casements adorn the most modern architectural projects, and our Mission® casements are sometimes configured to look like Double Hung windows.

01 - Basics

Casement Types

Our three main casement configurations are Traditional Rotogear, Pushout, and Fixed.
Mission® casements have a larger bottom rail (mission sash), these casements are sometimes configured to look like Double Hung windows.
We offer a variety of radius-top configurations.
Hinged on both sides, French casements create large openings (our French casement is only available as a pushout).

Oversized operable casements are only available as rotogear.

Frame Cladding

Our two standard options.

Our contemporary frame cladding moves the nailing flange towards the interior, because of this a jamb extension is needed to obtain a 4-9/16″ jamb depth.

Dual Glazing vs Triple Glazing

Our dual glazing uses our 1-11/16″ dual sash. Our triple glazing uses our 2-1/4″ triple sash, which moves the interior moldings further towards the interior.
