Material Information

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

The strength of aluminium allows Patio doors to be made with slim sightlines, resulting in a higher percentage of glass allowing more natural light into your home.

Aluminium doors require very little maintenance, just a wipe with a damp cloth when needed and a regular check to ensure the track is kept free from grit and small stones to ensure the doors continue to run smoothly. Aluminium is more resistant to the elements than uPVC and is not likely to warp or rot.


Our XL Aluminium Patio Door hardware can be manufactured in austenitic steel which is a marine grade finish for coastal applications. Please consider your choice of ancillary hardware carefully. Check out the finishes on our handles because it is attention to detail that helps make this unique product range so exciting.

Available in:
Anodised Silver

Safety & Security

Our patio doors are designed to discourage even the most determined intruder.

The KAT XL door is so heavy it is virtually impossible to jemmy open and therefore, this door can be left in a locked-open position to allow for ventilation. This is an extremely secure product, fitted with a 3 star diamond rated cylinder with kitemark to keep your home secure
