Material Information


Aluminium doors and windows have gained in popularity in the later half of the 20th century and aluminium is the optimum material for manufacturing windows and doors. It is widely specified by Architects for most serious new build and refurbishment projects.

The strength of aluminium allows 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 it is kept free from grit and small stones. Aluminium is more resistant to the elements than uPVC and is not likely to warp or rot.




With our huge range of exclusive doors we also offer you a complete range of accessories from handles, to threshold options, to opening configurations.

Our KAT French door handles are luxury products, made exclusively to a KAT design, crafted from Stainless Steel and guaranteed for 10 years. We offer a choice of six colour finishes so you won’t be stuck for choice.

Check out the finishes on our handles because it is attention to detail that helps make this unique product range so exciting.
