WHY ALUMINIUM?

Aluminium is the material of design.

Its flexibility and high strength allow unlimited design potential to help create our slim frame and larger glass panes. Unlike wood or PVC, aluminium is also resistant to deformation and does not need additional reinforcements. Aluminium ensures greater durability without any maintenance, making aluminium the material of choice for all applications.

Aluminium Maintenance

As well as being durable, aluminium windows are also incredibly easy to maintain.

A quick and simple clean every few months is enough to keep them looking their best, removing dirt and keeping them nice and shiny.
