New Double Glazing Window Locking Mechanisms

Double glazed windows are amazing for your home, with added noise reduction, increased warmth and excellent security with proper window locks, but one thing that can go wrong is that the locking mechanism on your windows can break over time. The good news is that you don’t have to replace the whole window if this happens. It is possible to simply buy the locking mechanism and replace just that instead, giving you a far cheaper option for continued window security and ease of operation.

What Are Replacement Window Locking Mechanisms?

Basically, the bit that makes your window locks work! Or a little more technically, uPVC window mechanisms are the gearing part located on the inside of a window that's driven by the handle you turn to open and shut your windows.

If you look at our range of mechanisms, you can click on the name of each one for more details on the type of lock, the sizes and what windows each locking mechanism will fit. There’s also a helpful diagram to show the measurements for each part of the mechanism, which may help you in selecting the right one for your windows.

And if you get stuck, when choosing what lock mechanism you need, you can always give our experts a call, chat to us on WhatsApp or send us an email. We’re always happy to help!
