Aluminium French Doors

Luxury Aluminium French Doors


French or Double Doors are often chosen for their stylish period appearance to allow access from inside the home to the garden and allowing plenty of natural light into your home. 

For tall, slim openings in a bedroom, inward opening French Doors are ideal creating a more open feel, perfect with a Juliet balcony.

Doors can be manufactured to open outwards or inwards, with the flexibility of the main traffic door either opening to the left or the right, to suit your requirements. Our fully glazed double doors are suitable for access to a Utility Room or as a Back Door and are fitted with a 3 star cylinder with Kitemark for your security. All of this is backed up with a 10 year guarantee.

Material Information


Aluminium doors and windows are back in vogue. Most Architects only specify aluminium for high-end projects because they know it is the optimum material for quality, low maintenance windows and doors.

The strength of aluminium allows us to craft doors with very 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 weather and does not attract dirt like uPVC.




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

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.


Safety & Security


A 5 hook lock and central dead bolt ensure that your French Doors are totally secure, giving you peace of mind. A lever lever handle is fitted to the master door. In addition to this, KAT fit 3 star cylinders to all doors.
