All in the details

Why should you choose aluminium for your windows and doors?

Aluminium is regarded as one of the best materials when it comes to durability, aesthetics and security of windows and doors.  Aluminium is also strong but lightweight. This allows slim window frames and larger expanses of glass, creating panoramic view and flooding your home with natural light. Let's look at the importance of choosing aluminium as a material for your windows and doors.

Cleaning & Maintenance of Aluminium Windows and Doors

All you need to do to keep your windows and doors looking their very best is to wash them down a few times a year to get rid of any dirt or dust. That’s all there is to it. They don’t crack or fade in the sun and there’s no scrubbing or painting required – leaving you more time to relax and enjoy your view.
