TOP FAQ

Here are some frequently asked questions about these windows.  If you have other questions, please get in touch with us!

Casement windows are operated by turning a handle, which moves the window on its hinges, allowing it to swing open or close.

  • When the handle is turned, a metal arm mechanism, often called an operator, pushes the bottom of the sash outward while pulling the top inward.
  • The casement stay, a type of bar or metal arm attached to the bottom of the window, holds it in place when it’s fully open to prevent it from slamming shut due to wind.
  • For added security and weatherproofing, a multi – point locking system is engaged by a single lever; this draws the sash tightly against the frame’s sealing gasket.
  • High – quality weather stripping encircles the window’s perimeter ensuring that when closed, casement windows are sealed and extremely energy efficient.
  • They have an advantage over double-hung or single-hung windows because their seal can be tighter due to less movement of individual parts which results in better insulation from noise and outdoor temperatures.
  • Tensioning devices are sometimes included in modern designs so that even when open, casements remain steady and resist being moved by exterior forces like strong gusts of wind.

Yes, you can crank Provia Casement Windows open all the way for full ventilation because their design allows the entire window sash to swing out. Homeowners may select a non-washable casement hinge, which pivots closer to the frame, allowing
greater viewing area and better function for egress requirements.

Exploring the advantages and drawbacks of casement windows provides homeowners with valuable insight into their suitability for various home designs and personal preferences. Below is a comprehensive summary of these aspects presented in a table format.
