About Us

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


A bit about us here at KAT. We’ve maintained our position at the very forefront of the industry thanks to an on-going commitment to product development, quality and innovation. This has enabled us to steadily grow the business and we now have manufacturing and customer service teams in Macclesfield and Kilmarnock, numbering over 100 employees. Our factories are capable of producing doors and windows for residential projects and new build and commercial applications like shopfronts or curtain wall.

The strong reputation we’ve built for ourselves over the past 20 years has led to us being chosen as the preferred supplier for countless high-profile and prestigious projects across the UK, including conservation areas where our PVCu sliding box sash window is regularly specified.

Rather than just follow the market, we prefer to set trends, which is why for over 20 years we have only worked with the best raw material suppliers in Europe; like Kawneer and Veka.

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, our Design Partners possess individual 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 probably the leading company providing high-end bespoke glazing solutions, in our chosen markets.
