GEORGIAN SPLENDOUR

I love the elegance and balanced proportions of Georgian architecture, but few things can spoil such a property more than unsympathetic restoration and replacement windows out of keeping with the overall design ethic.

Sash windows from Jack Brunsdon & Son are designed to fit in beautifully – as this case study illustrates.

This Georgian property near Stokenchurch in Buckinghamshire was rather let down by wooden single-glazed box sash windows that had never been replaced. 

The homeowners agreed: "Our existing sash windows were very old, rattled in bad weather and were in need of sensitive replacement. As we live in an area of outstanding natural beauty the aesthetics of the new windows had to be absolutely correct, replicating the existing narrow sashes, but with improved insulation, noise reduction and longevity."

After a careful site survey, the solution decided upon was traditional box sash windows manufactured in Engineered European Redwood with hardwood cills. This replicates a time-honoured tradition in Britain of building sash windows in pine (Redwood is a species of pine) with oak cills.

The sashes were hung on weights in the traditional manner, suspended by smooth running brass chains. Critically, Jack Brunsdon & Son opted for slim box sash windows – the slimmest on the market. This meant that dimensionally the new windows were almost exactly the same as those being replaced. It also meant minimal disruption internally. Finally, slender 18mm glazing bars were fitted to replicate the original small pane glazing.

The products look entirely authentic, but carry the benefits of 21st century technology, including high-performance double-glazed units, anti-warp, anti-twist timbers and superior paint finishes for a long life of problem-free use. The windows were pre-finished in white prior to arrival on site. The paint treatment is extremely long-lasting – we guarantee it for eight years – so ongoing maintenance is low.

The homeowners are delighted with the results. "We did a fair bit of research on the internet, which is where we came across Jack Brunsdon & Son. While their windows were more expensive than uPVC alternatives, the design and quality was exactly what we were looking for.

"The installation was fine, with minimum inconvenience and very little mess. With the new windows installed we have noticed that noise levels have dropped to virtually zero and there were no rattles, even during the autumn storms.

"Jack Brunsdon & Son did a good job with good products and aesthetically the house looks just right. We are now looking forward to seeing what difference they will make to our heating bills.”
