Aluminium Casement Window Materials

Aluminium is a very strong and lightweight material. It naturally generates a protective oxide coating, making it virtually resistant to corrosion. Because of that, aluminium is one of the most durable frame materials available. The lifespan of these casement windows can therefore be measured in decades rather than years, making them immensely popular with homeowners.

Aluminium Casement Window Designs

As with a uPVC casement window, our aluminium systems are available in a vast range of designs and configurations. This makes them a great option for new builds, or as a like for like replacement for antiquated steel. Top hung, side hung, and fixed frames can all be specified for projects. As you’d expect with Quickslide, there is a host of customisation available as well.
