What Are Casement Windows?

Casement windows are attached to a frame with one or more hinges. They open and shut like a door, either out or in. Historically, this type of window was popular before the introduction of sash windows, with many having leaded glass panes. Unlike contemporary casement windows, the original design opened inwards, often with shutters on the outside of the window frame.

Early casement windows had matching hardware, usually crafted in black iron, likely to have been forged by the local blacksmith. This changed in the Victorian era when brass was the favoured finish.

Stays And Fasteners

Window latches and stays are used to prop open the window at certain angles depending on the holes chosen.

Casement fasteners keep the window shut securely in place and can also have the additional feature of a lock.

How To Fit A Casement Window Stay (peg style)

  1. Begin by unscrewing and removing the original stay used to hold open your window (if there is one present). Fill the holes left by the fixings with a wood filler.
  2. After the filler is completely dry, sand the wood smooth and paint, stain or varnish the newly filled area as required.
  3. After closing the window, position the pins along the bottom of the window frame. The closer the fixing bracket of the stay against the opening edge of the casement, the more manoeuvrability you will have when opening and closing the window.
  4. Fit the stay onto the pins. This will set the correct height for the stay. Using a pencil, dot the position of the stays fixing holes onto the casement frame.
  5. Drill pilot holes and screw the stay to the casement frame.
  6. Close the window and ensure it is tight against the frame. Position the pins under the stay so that each line up with holes to both ends of the stay.
  7. Move the stay out of the way and pencil in the position of the fixing holes on the bottom of the window frame for each pin.
  8. Drill pilot holes and screw the pins into the frame.
  9. Make sure the stay fits over the pins and the window is shut tight.

    Hi Cindy, there are no exact rules when it comes to choosing window stay sizes, but you will need something that is large enough to hold your window open securely. We recommend the 12" for your two larger windows. For the 17.5" size window you could go with either the 12" stay to match, or the slightly smaller 10". Please call our friendly team if you need any further help or advise. Thanks.

    I have three windows that I I would like to purchase stays for, 17.5", 22" & 30" wide. What size stays would you recommend?
