KAT was established in 1998 and is a specialist manufacturer of uPVC and Aluminium Doors, Windows and Roof Glazing, in the UK.


Quality and service are important to KAT and to this end, every Bifold Door, Sliding Patio Door, French Door, Entrance Door, Box Sash Window, Casement Window, Flat Roof Light and Lantern Roof is photographed after it has been quality inspected and aluminium doors are filmed and recorded whilst operating. This way KAT’s team know the product is fully functioning and perfect before it leaves the factory, but more importantly KAT’s customers know it’s right, every time.
