Choosing your doors and windows is as much about choosing the manufacturer that installs the most secure locks, as choosing the style and quality of uPVC double glazed products.

A cheap lock makes your supposed 'high quality' windows and doors about as useful in your attempt to enhance your home's security as a chocolate fire-guard - seriously.

Make sure you understand the types of locks - and understand the phrases "5-point locking" doesn't necessarily mean what the sales rep hopes you think it means.

While you are choosing your double glazed windows and doors, take a good look at various locks available and insist on viewing the test certification that relates to the doors, the windows AND the locks that were installed in the products when they were tested and make sure the same locks are used in the windows and doors you buy.

Oh yes, the 5 point locking myth.

Every sales-person for the last 20 or 30 years has been saying their windows and doors have 5 points locking systems.

Well it actually came about from insurance companies.

The insurance companies said that they want a '5 lever lock'.

A 5 lever lock is a lock that fits in a wooden door.

Typical of the Double Glazing industry and some of the cowboys that are in it, what they started to sell then was a lock which had some very small roller cams that roll up and down the side of the door and they slot behind a keep and there's five of them so they said "this is 5 point locking"...
