Casement Windows FAQs

Casement windows are the most energy efficient opening window because the window frame pushes against the outer frame and creates an airtight seal that keeps the cold air out and the warm air in. For this reason, casement windows are better than most other window styles. A sliding window needs to be flexible so that the window can slide open and close and because of this, it is not as energy efficient as a casement window.

Any new double glazed window will be better than the older style of windows from years ago as there have been so many technological advancements since the last time your property might have had new windows. Casement windows are one of the most efficient and cost-effective windows on the market today and they can fully transform the look and feel of your home.
