NJS Sash Windows Featured in House Beautiful Magazine

Written by the NJS Sash Windows Team

We’re proud to announce that NJS Sash Windows has been featured in House Beautiful, one of the UK’s leading home and interiors publications.

The article explored how traditional period homes were cleverly designed to stay cool during warmer months — long before modern air conditioning existed.

Our founder, Nick Smith, was invited to share his expertise on the natural ventilation benefits of traditional sash windows and explain why these historic designs are still so effective today.

“Most homeowners have no idea these windows were designed to naturally cool a room. By opening both the top and bottom sash, air circu

The Forgotten Genius of Traditional Sash Windows

For centuries, Georgian, Victorian, and Edwardian homes have used sash windows not just for their elegant appearance, but also for practical ventilation.

Unlike modern windows, traditional sash windows allow you to open both the top and bottom sections at the same time. This creates a natural airflow system:

✓ Warm air rises and escapes through the top opening
✓ Cooler air enters through the lower opening
✓ Fresh air circulates naturally throughout the room

During hot weather, opening each sash slightly — around 10–15cm — can often create better airflow than simply opening one window fully.

It’s a simple piece of historic engineering that many homeowners have forgotten.

Trusted Knowledge Built From Years of Experience

Being featured by a national interiors magazine is a proud moment for NJS Sash Windows, but our knowledge comes from many years working directly with period properties.

Since originally establishing the business in 2005, we have restored and repaired traditional timber windows across Stamford, Rutland, Peterborough, Cambridge, and beyond.

We specialise in:

• Traditional timber sash window restoration
• Rotten timber and sill repairs
• Sash cord replacement
• Draught-proofing upgrades
• Slimline double glazing conversions
• Handmade replacement timber sashes
• Repairs suitable for period and listed properties

Our aim has always been simple — preserve the character of original windows while improving comfort, performance, and everyday use.

Preserving Stamford’s Period Homes

Stamford is famous for its beautiful Georgian architecture, historic streets, and traditional properties.

Many of these homes still have original sash windows that have lasted well over 100 years. With the right restoration, these windows can continue performing for generations.

Replacing original timber windows is not always the best option. In many cases, careful restoration can bring them back to life while keeping the authentic character of the building.

Why Restore Original Sash Windows?

A properly restored sash window can:

✓ Reduce draughts
✓ Improve insulation
✓ Maintain original period features
✓ Improve smooth opening and closing
✓ Extend the life of historic timber
✓ Protect the appearance and value of a property

Traditional craftsmanship combined with modern restoration methods can achieve impressive results without losing the charm of the original windows.

As Featured in House Beautiful

We’re delighted that our knowledge of traditional sash windows has been recognised nationally.

Period windows are more than just a feature — they’re part of British architectural history, and understanding how they were designed helps homeowners appreciate why many are still working hundreds of years later.
