One type of locking mechanism that is commonly used in uPVC double glazing windows is the offset window locking espag mechanism. This mechanism consists of a metal strip that runs the length of the window frame and is operated using a handle or key. When the handle is turned or the key is locked, the strip moves up or down to engage with a metal striker plate on the window sash.
Offset window locking mechanisms come in a variety of types, including espag, shootbolt, and reverse action. Espag is perhaps the most common type, and it consists of a flat metal strip that sits flush against the window frame. When the handle is turned, the strip moves in a vertical motion to engage with the striker plate on the window sash. This type of mechanism is favored by many for its ease of use and reliability.
Shootbolt mechanisms, on the other hand, use a series of locking pins that shoot out from the side of the window frame to engage with the striker plate on the window sash. This type of mechanism is often used in larger windows, as the multiple pins provide added security and stability.
Reverse action mechanisms work in a similar way to espag mechanisms, but with one key difference: the locking strip moves horizontally instead of vertically. This type of mechanism is often used in windows where the handle is positioned at an angle, such as in tilt and turn windows.
No matter what type of offset window locking mechanism you choose for your uPVC double glazing windows, it is important to ensure that it is installed correctly and maintained regularly. This will help to ensure that your windows provide the security and energy efficiency benefits you require.
If you are looking to upgrade your window locking mechanism, consider the benefits of offset window locking mechanisms. With their ease of use and reliability, they are an excellent choice for homeowners looking to improve the security and energy efficiency of their uPVC double glazing windows.
