The casement window is a tall, narrow window that opens by cranking a handle. Casements can open out towards the left or right. Our casement window is designed with three continuous seals of weather-strip around the window’s perimeter, you won’t feel any air leaking into your home, a feature we are proud to back as part of our Industry Leading Life-Time Warranty. Our choice in quality hardware allows all casement windows over 16" wide to open to a full 90° angle, allowing for easy cleaning of the outer pane of glass form within your home.

Much like the rest our our vinyl windows, the casement windows are made from unplasticized PVC (UPVC) powder with impactors and UV protectors. Profiles are multi-chambered for superior insulation and strength. Sashes in single and double-hung windows are tilt removable. The inner sash in single slider windows lifts up and out. All corners are fusion welded and we use only ¾" insulating glass. This method of construction assures a warm edge spacer which is also flexible to lessen the chance of seal failure.
