Material Information


Aluminium doors and windows have regained in popularity since the turn of the 21st century. Aluminium is now the optimum material for manufacturing doors and windows.

It is widely specified by architects for high-end, luxury new build and refurbishment projects. Aluminium doors require very little maintenance, just a wipe with a damp cloth when needed and a regular check to ensure they are kept free from grit and small stones. Aluminium is more resistant to the elements than uPVC and will not require regular maintenance.




KAT door handles are luxury products, made exclusively to a KAT design and guaranteed for 10 years.

A lever handle is fitted to the inside of Kastle doors with a long pull bar externally.



Safety & Security


KAT’s Aluminium Entrance Doors are fitted with the best multi-point locking system on the market – plus a 3 star diamond rated security cylinder with Kitemark.

Once the front door is closed, it is automatically locked, keeping you safe in your home.
