KAT UK is understandably proud to now offer customers the highest ‘A’ rated PVCu vertically sliding sash windows available in the UK. Beating all previous claims, they hold an A+11 and A+9 rating on the two main KAT window suites. KAT UK is one of the select few manufacturers able to achieve an ‘A’ rating on sash windows with a deep bottom rail, to match up with sight lines on Victorian sash windows.
KAT UK always invests heavily in product certification and testing to ensure they offer their customers products that comply with and in most cases easily exceed current regulations and standards. They now hold more Window Energy Rating certificates than any other sash window manufacturer and offer a wide choice of either A, B or C ratings on both Elegance and Universal ranges.
