Window Security

Window handle locks

The most common window handle on modern double-glazed windows are key operated espag handles, with a flat metal strip design. When the key is turned to lock the window, metal studs that are placed on the inside of the handle catch into a plate that’s on the window frame. Keyless non-locking window handles are also an option, featuring a user-friendly internal button that’s ideal for fire-escape windows.

Our window handle collection also includes pear drop handles, pendant handles, and monkey tail handles. Our window handles work in the same way as an espag handle for simple functioning but aren't key-operated. Their specification provides the same protection for your home from the outside and inside. They're compatible with both multi-point locks and shoot bolt systems.

Multi-point locking systems for your South East home

For improved security in aluminium or uPVC windows, all of our window styles are fitted with multi-point locks. Most multi-point lock systems include three vertical slots and when closed these bolt to three hooks on the window frame. Unlike older window security locks that only bolt in one place, the window is secured at several points around the frame—multi-point locks can reduce your home insurance costs.

Shoot bolt locks for double glazed window security

Shoot bolts extend inwards or outwards at the top and bottom of the window, securing it to the outer frame. The adjustable mushroom cams secure the frames tightly together. Not only does this increase the security of a window design, but it also works as a protective seal keeping the sash and frame tightly closed and the weather out.

Window frame beading

Window beading runs along the edges of the window, holding the glazing panes firmly in place. It serves to protect the glazing from movement like a strip of putty in a traditional wooden framed window.

Windows can either be internally or externally beaded. If it’s external, the beading will be visible on the outside of the window, whilst internal beading is hidden within the frame.

External beading is common on timber windows and heritage uPVC windows as it will retain the authentic wooden appearance found on older properties. Nowadays, most modern double or triple glazed windows are internally beaded.

Window restrictors

Commonly used as a casement window lock, they can also be incorporated into tilt and turn and bay windows. Window restrictors constrain window opening. Choose from cabin hooks, concealed restrictor arms, cable restrictors, and sash jammers that are located on the window frame.

Sash window security in Ipswich, Oxford, Essex and Suffolk

Sash windows's design calls for different security features:

• Sash window lock/fastener – fixed to the middle of a vertical sliding sash window. When locked, it prevents the window from being opened from the interior or exterior.
• Sash window stops – used for both home security and ventilation, they’re located on the left and right of a sash frame and stop the window from being completely opened. For homeowners with young children especially, this is an important security feature to incorporate into the sash window design.
• Meeting rails – This is where the top rail of the bottom window and the bottom rail of the top window meets. Their precise configuration ensures that they sit tightly together, stopping any movement when closed, ensuring unwanted intruders can’t pick or force their way through the sash window.
