Will my UPVC windows discolour?

No, all uPVC windows are now colour fasted so the colour is specially set and it does not degenerate.

How can I improve the security of my doors and windows?

We have a number of ways to upgrade the security of our products. The main way would be to upgrade the locks/ barrel to a more secure/ anti bump/snap barrel, or to change the glass to laminate glass, this turns one of the weakest points of any glazing product into one of the strongest!

What is the maximum bi-fold door size?

The largest sash width for our bi-fold doors is 1.2m which is dependent on the material, the overall frame size of the bi-fold door will be slightly larger than the amount of sashes multiplied by the sash width. We are able to make Aluminium doors anywhere from 1.6m to 9.6m and they can go up to 2.5m high!

We are able to quote oversized work if it meets the correct criteria on a special basis.

Are bi-fold or sliding doors less secure than a normal door?

As with any external door, security is a high priority. All of the doors we supply and install come with multipoint locking systems, toughened glass and are internally beaded. With this in mind remember you can also upgrade your locks and glass if you would like added security.
