Window Security

I felt that it was important for me to write this blog because of the increase in crime and through experience working as a carpenter. We thought that we would share a few tips on how to make your home safer and ensure your insurance policy is valid

Most insurers require key-operated window lock on all windows accessible from the floor or a flat roof.  Some even say if you can climb a gutter and get to the window, those windows also need to be key-operated.

 

There are two main types of wooden windows and these are:

Wooden sash windows - These are windows that go up and down.

Casement windows - These are the type windows that are hinged and open out, ether from the side or the top.

 

Window Locks

There are the various types of locks available:

Auto-locking locks - When you close the window, it will lock automatically and to open the lock, you just need to put the key in and turn it.

Manually-locking locks - These require you to push down or around a part of the lock in order to lock onto the other part.  Once this is done, insert the key and lock the two parts together. To open the lock, turn the key and this releases the two parts then opens the window.

 

Various types of window locks.

Wooden Sash Windows

Sash windows are the type of window that goes up and down.  You can get various types of locks that fit on sash windows.  The main ones, which are usually fitted in the middle of the window, are called fasteners.

 

Heritage Fitch Fastener

The Heritage Fitch Fastener locks by turning the lever that is mounted on the inside window so it will lock into the piece on the outside window.  These locks are available in various colours, including brass and chrome.  This lock does not meet insurance standards, as it doesn’t lock with a key.

 

Quadrant Sash Window Fastener

The Quadrant Sash Window Fastener is mounted half on the outside sash window and half on the inside sash window.  The lever part is on the outside sash window and this locks into the keep mounted on the inside window.  This style of sash fastener is available in different colours, including brass and chrome.  The lock does not meet insurance standards, as it does not lock with a key.

 

Brighton Sash Fastener

Brighton Sash Fasteners have a swing-over threaded piece that sits on the outside sash window.  This piece flips over and is seated in the grooved keep part that sits on the inside sash window.  Once in the groove, the nut is tightened in order for both parts to fit together.

  There are many different types of locks you can get for sash windows that comply with most insurance policies, as most polices only require that they be locked with key- operated window locks.  The main types installed are shown below

 

Locks suitable for Sash Windows 

Sash Stops

Sash Stops are great and are fitted to the outer sash window or frame. They prevent the inside lower sash window from moving past the outside sash window.  You can fit one right on top of the inner window and prevent the window from moving at all.  You can also fit a stud higher on the window to allow for an air gap but still have the window remain locked.  If your window is wider than 600mm, we advise fitting locks on both sides of the window. 

 

Sash Bolts

Sash Bolts have part that is drilled into the inside sash window.  The bolt is then screwed through the inside window into the outside window and locked in place with the key.  To unlock the Sash Bolt you simply turn the key and the bolt comes allowing you to lift the inside sash window or pull down the outside sash window.  

Casement Windows 

Wooden casement windows are the windows that are hinged either on the side or top and open outward. The older style wooden casement window usually has a casement stay and fastener.

Casement Fasteners & Casement Stays

The newer style wooden casement windows have a single handle on the inside and a multipoint locking system (Usually found on a UPVC or double glazing mechanism).  This type of system is located on the side or underneath the window, and is not usually visible from the inside.  

The newer style casement windows meet insurances standards if they have a handle that is key-operated and also have a multipoint locking system.  The older style casement window needs to be fitted with a key-operated lock to conform to insurance standards.

On older style wooden casement windows you can get locks that operate automatically - you just shut the window and the locks are secured, and you open them by turning the key, or you can get manually-operated locks—when you close the window you manoeuvre the locking parts together, then lock them shut with a key.  All of these types of locks are made by various manufactures, including Chubb, Union, Yale, ERA and more.

 

Casement Window Locks (non-auto locking)

This type of lock has a piece fitted on the window frame and a piece fitted on the window. To it lock it you shut the window and flip the piece with the keyhole in it around the fixed piece on the frame. When you turn the key, a locking screw is threaded into the piece fixed to the frame (sandwiching both together, tightly).

 

Wooden Casement Window Locks (auto-locking)

This type of lock has one piece fitted on the window frame and the other part fitted on the window.  When the window is closed, the piece on the window automatically locks into the piece on the frame.  To open the window, you simply turn the key and push the window open.
