Material Information


Aluminium windows have gained in popularity in the later half of the 20th century.

The strength of Aluminium allows windows to be made with slim sightlines, resulting in a higher percentage of glass allowing more natural light into your home. Aluminium is more resistant to the elements than PVCu and Timber and is not likely to warp or rot. Windows require very little maintenance, just a wipe with a damp cloth when needed.

Aluminium is the optimum material for manufacturing windows and doors and that is why it is widely specified by Architects for most serious new build and refurbishment projects.




For your safety and security, we fit key locking handles to all of our windows.

There are 5 handle colours to choose from:

  • Black
  • White
  • Gold
  • Satin Chrome
  • Polished Chrome




Safety & Security


We take your security very seriously and without compromise fit each of our windows with key locking furniture, in five different colours.

The MACO RAIL locking handle conforms to PAS 24:2012 enhanced security performance requirements for doors and windows in the UK. The friction hinge conforms with fire egress regulations and has an easy clean option fitted as standard.
