KAT successfully reflects the character of a conservation area

Case Study | Box Sash Windows,

Very often, reflecting and preserving the character and architectural integrity of a building are key considerations when choosing a box sash window solution.

When Mr. Jenkins purchased a three-storey building in Ceredigion, Wales, he discovered that the KAT Mayfair Box Sash Window possessed all the design qualities necessary to meet both his high standards and those of the local authority.

With the original timber box sash windows clearly in need of replacement, Mr Jenkins was sensitive to the fact that not only were all of the neighbouring houses fitted with traditional timber windows; they were also situated in a conservation area.


There were environmental and climatic considerations too. Living in a coastal area within a mile from the sea meant that opting for replacement timber windows would have meant repainting them annually to provide protection from the elements. From both a practical and aesthetic perspective, he therefore decided that his best course of action would be to seek a suitable alternative to timber.

Having heard about Mayfair box sash windows, with their distinctive deep bottom rails and authentic woodgrain effect finish, he decided to contact KAT. He was pleased to discover that besides enjoying all of the attributes of the hugely popular KAT Elegance range, the Mayfair is also manufactured along similar lines to time-honoured joinery techniques, with fully mechanical jointed outer frames and sashes with deep bottom rails designed to faithfully replicate the look of traditional timber.

It’s a look which is completed by bespoke Georgian bars which sit flush with the sash and a decorative hook and claw cam-catch; another bespoke design feature developed specifically for KAT.

Once happy with his choice, it was time to see if his selection could satisfy the necessary planning criteria. Mr. Jenkins contacted his local authority to discuss replacing his existing timber windows with modern uPVC sash windows. Fully prepared with a sample window and profile drawings supplied by KAT, he attended several meetings with the local authority and was absolutely delighted when they gave him permission to fit Mayfair windows.

After being supplied with the final sizes, KAT was able to manufacture and deliver the windows within two weeks. Freed from the need to give his windows an expensive new coat of paint every year, Mr. Jenkins now benefits from the peace of mind that comes with having highly secure, high impact, durable uPVC frames which are virtually maintenance free.

From an environmental point of view, he’ll also be warmed by the fact that Mayfair windows offer excellent thermal properties.

As Steve Williams, Operations Director of KAT observed, “When replicating the look of timber, attention to detail is everything. Even from 6ft away, it’s extremely difficult to tell if the Mayfair is of timber or uPVC construction.”

Steve continued “KAT prides itself on developing products which combine innovative features with market leading design. Being able to faithfully replicate the character of a location with such a high degree of precision, is one of the innovations we’re most proud of.”
