Double glazing window restrictors are a safety and security device. They can help deter burglars and prevent falls from windows. They enable windows to be opened up to 100mm for ventilation while securing the window against opening any wider. As more of us come to understand the need for adequate ventilation, the importance of window restrictors also increases.

When considering window security there are plenty of options for double glazed window restrictors depending on the needs of the situation.

Window restrictors are also sometimes referred to as window cable restrictors or window locks.

You will want to consider whether you want a window restrictor that locks with a key such as the Pro 5 or Pro 5 Duo. These types are usually required in places that care for people who might be vulnerable, such as when installing window restrictors for care homes.

You might prefer a keyless window restrictors with a Twist mechanism such as the pro-Twist. This option is often chosen by households who are concerned about misplacing a key!

You might prefer cable window restrictor option that is permanently in place to prevent tampering and accidental release such as the Perma window restrictor. Using this option the window can not be opened more than 100mm unless the entire mechanism is removed.
