Windows - Single & Double Tilt Slider - London and Southwestern Ontario

Low maintenance Double Tilt Slider Windows feature two window sashes that open into your room for easy cleaning. Double tilt slider windows come in both regular double tilt window and butterfly double tilt window opening styles, the window operation is based on a durable and strong stainless steel window pivot. The ability to open both window sashes by swinging them in allows for the best ease of window cleaning allowing you to clean both sides of the window sash from the comfort of the inside of your home.The double tilt slider window can be opened from either the left window sash to right window sash, or from the right window sash to the left window sash to provide optimum window ventilation and operation versatility.

Our Single Tilt Slider windows offer a single tilt-in sash with the operational window based on a durable and strong stainless steel window pivot , combined with a durable, fixed sash and the other side. The window venting area is approximately half the overall window area and comes complete with a window screen on one half, and a clear view window sash with no screen on the other window half. The single tilt slider can be ordered with either the left window sash or the right window sash operational.

All our slider windows combine great looks and excellent efficiency requiring virtually no ongoing maintenance. Our slider windows can also be coupled together under a fixed picture window to allow for even more window option styles when choosing the window operation and appearance that best suits you and your home.
