Quality Kawneer aluminium sliding patio doors designed & manufactured in the UK


Our aluminium sliding patio door system is perfect for smaller openings up to 5 metres wide.  This patio door features slim sightlines but is very secure. When coupled with low emissivity glazing, these thermally enhanced doors achieve very acceptable U values.  These inline sliders are perfect for applications where it is desirable not to open in or out of a room and they offer a far larger glass area than a set of French double doors.

KAT awarded North West Enterprise Award for Best Patio Company 2017.

It’s not the door you look at but the view through the door to the world outside.

Our standard patio doors allow so much light in because there are so few upright panels.  Incorporate a KAT patio door and add a true sense of contemporary design to your project.



Blinds Within Glass


Integral venetian blinds are made to fit neatly between 2 panes of glass, offering a contemporary look for Sliding Patio Doors in a choice of 10 colours; White, Yellow, Hay, Sage, Sky, Cream, Putty, Silver, Dark Silver and Dark Grey. 

Raising and lowering of the blinds is controlled using either a Rotational Wand, Rotational Knob or a Cord system. The blinds carry a 5 year guarantee, are maintenance free, conform to BSEN 13120 Safety Standards and are suitable for 28mm double glazed door sashes up to 1200mm wide.

Material Information


Aluminium offers the widest possible choice of colour options.

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 PVCu and is not likely to warp or rot. We offer a 10 year warranty on standard paint in a choice of 7 colours or 20 years warranty on Marine Grade paint.




We fit a 400mm cranked bar handle in brushed steel with a Pentalock 5 point enhanced security lock to KAT Kawneer Inline Patio Doors.







Safety & Security


Our aluminium in-line sliding patio doors are designed to discourage even the most determined intruder, thanks to our high security locking systems. 

All KAT doors can have a 3 star diamond rated security cylinder with Kitemark.

Our patio doors have integrated anti-lift systems designed so they cannot be lifted off the track from the outside, when in the locked position. Plus, aluminium is a more robust material than timber or PVCu.
