100 Series

Casement Window


100 Series casement windows are hinged on the side, with the sash opening horizontally opposite the hinge. This allows for full ventilation from top to bottom of the window opening and the extended sash can catch the breeze and direct it into the house for better air flow. Made with our sustainable Fibrex® composite material, it's our budget-friendly casement window.
