About Us

UK based manufacturers of specialist glazing products - Aluminium, Timber and PVCu.

Majoring on Bifold Doors, Patio Doors & Sash Windows. Also manufacture Aluminium and Timber Casement Windows, Tilt Before Turn Windows and French Doors.

KAT UK has maintained it's position at the very forefront of the fenestration industry thanks to an on-going commitment to product development and innovation. Manufacturing and showrooms in both the north and south of the country; Macclesfield in Cheshire and Newhaven in Sussex, where 55 members of staff are employed.

KAT's strong reputation has led to being chosen as the preferred supplier for countless high-profile and prestigious projects across the UK, most notably in conservation areas where the KAT Box Sash Window is a very popular addition in either Timber or PVCu. KAT predominantly utilises UK sourced materials and systems.

Rather than follow market trends,KAT prefers to set trends, which is why over the years the product portfolio has extended to embrace Aluminium, Timber and PVCu manufactured products; one of the few companies to do so. Add to that a 10 year warranty and some of the most sophisticated and stylish contemporary designs available and it’s undeniable that KAT more than satisfies its' long-standing motto of ‘Life Engineered’.

However, far from solely focus on design, KAT ensures its offerings provide a superb level of energy efficiency and security; two key attributes for any reliable window or door solution.

This is all backed up with a tight and extensive network of ‘Design Partners’. Situated throughout the UK and Ireland, our Design Partners each possess their own individual showrooms and are responsible for fitting our products to the highest of standards in thousands of homes each year. It is largely due to their continued support that KAT has blossomed into a sustainable and customer focused business, one of the UK’s finest.
