Windsor Next Dimension casement windows are designed with easy operation in mind, allowing you to bring the outdoors inside. With a multi-point locking system, featuring a number of lock points along the sash to create a weathertight seal, our casement windows offer superior energy efficiency. Performance is made simple and fluid through a single lock lever located low on the casement, meaning every window is easy to operate, regardless of where it’s placed.

Choosing vinyl doesn’t mean you have to give up the "custom" look or creative design opportunities. Windsor’s Next Dimension Series lets you design a one-of-a kind look with unlimited choices in sizes and shapes.

Choose from standard half rounds, quarter rounds, ellipses and octagons.
