About Us

When it comes to designing, manufacturing and supplying bespoke window and door products, KAT has always been ahead of the game.


We have maintained our position at the very forefront of the industry thanks to an on-going commitment to product development, quality and service. This has enabled us to steadily grow the business and we now have manufacturing and customer service teams in Macclesfield and Kilmarnock, numbering over 50 employees. Our factories are capable of producing doors and windows for residential projects, new builds and commercial applications, including; automatic doors, shopfronts, curtain wall and glazed screens.

The strong reputation we’ve built for ourselves has led to us being chosen as the preferred supplier for countless high-profile and prestigious projects across the UK, including conservation areas and high-end residential new builds.

Rather than just follow the market, we prefer to set trends, which is why we only work with the very best pan-European system suppliers; Veka uPVC and AluK Aluminium.

We ensure our products incorporate the most up to date thermally efficient materials and they must pass all the relevant security tests, as specified by British Standards.

Our manufacturing expertise is backed-up by our carefully selected and trained network of independent ‘Design Partners’. Covering the UK and Ireland, these Design Partners usually have showrooms and are responsible for specifying, surveying and installing our products, to the highest of standards in thousands of homes each year. It is largely due to their continued backing and support that we continue to be regarded as leaders in providing high-end bespoke glazing solutions, in our chosen markets.
