  4. The Hinges: Located on the side, these enable the sash to pivot external.
  5. Multi-Point Locking System: A high-security feature that locks the window at several points along the vertical frame with a single lever.
  6. Weatherstripping: Resilient material utilized to seal the gaps between the sash and the frame to avoid air and water leak.

Why Choose Casement Windows? Secret Benefits

3. Exceptional Energy Efficiency

Casement windows are extensively considered the most energy-efficient operable windows. This is since the window sash presses strongly against the frame when closed, developing an airtight seal. High winds actually enhance this seal by pushing the sash harder versus the weatherstripping.

4. Enhanced 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. Moreover, the crank-operated system is challenging to control if the glass is undamaged.
