Key Benefits
Casement windows use numerous unique benefits over other window types, particularly concerning ventilation and energy preservation.
1. Superior Ventilation
Because the sash opens completely outside, it acts much like a sail on a boat. It can catch side breezes and funnel fresh air into the home. This makes them ideal for cooking areas or restrooms where moisture and smells need to be tired quickly.

High winds actually improve this seal by pressing the Sash Window Refurbishment harder versus the weatherstripping.
4. Boosted Security
The locking mechanism of a sash window is incorporated into the frame, making it really tough for intruders to take advantage of the window open from the outside. Additionally, the crank-operated system is tough to manipulate if the glass is intact.
