Stylish Sash Windows

Get Your Free Quote

Maintain your home’s traditional charm while enjoying all the benefits that come with a modern sliding sash window. Sash windows have been a stylish window choice in the UK for centuries, but single glazed, timber-framed windows simply don’t perform in comparison to modern technology.

Sash windows have remained popular because of their excellent ventilation and aesthetic appeal. Now you don’t have to sacrifice any of those elements to have modern, high-performance windows that give you light, ventilation and ease of use.

Smooth Operation Sash Windows

The easy gliding operating system means that opening and closing are smooth, while the upper and lower windows tilt inward for safe cleaning and ultimate ventilation. Robust design and aesthetically pleasing appearance, our vertical sliding sash windows bring out the character of any home. With near-invisible joints and the grace of the run-through sash horn.

While sash windows harken back to a more traditional style, their modern construction gives a variety of benefits. Being made of high quality uPVC, these windows will withstand the effects of weathering. Unlike traditional wood and materials, modern uPVC doesn’t rot, warp or swell in the same way. This means that your new uPVC windows will withstand even the harshest of weather.

Energy Efficient Double Glazing

Double glazed uPVC windows, such as our sash windows, are a great addition to the modern home. With their modern design, they’ll help you create an energy efficient environment. For you as a homeowner, that will bring a couple of key benefits. With greater energy efficiency, you could experience less temperature fluctuations through the months. This could even mean a reduction in energy bills!

Security is a top concern for us here at Britannia windows. We want to make sure that your uPVC windows keep your home truly safe and secure. Modern uPVC profiles such as those used in our sash windows are impact resistant. Combined with our double glazing and multi point locking systems, you’ll enjoy a secure environment. You and your family are in safe hands with Britannia.

Frequently Asked Questions

How does a window sash work?

Consisting of two or more panels, a sash window works by having at least one panel that can move vertically up or down. If your window is single hung this means that just one panel moves.

Do you have a showroom?

Even better, we have a few! We have a range of showrooms throughout the south of England where you can see our sash windows in person. Visit us in Bristol, Clevedon or across cities in the South East and South West today!

Where are your sash windows made?

We manufacture all of our sash windows from our base in Clevedon. By manufacturing in house, we can offer the highest quality as well as a range of customisation options.

How secure are they?

They are a brilliant way to let in light and air, ensuring your room has a fresh feel to it. Our double glazed casement windows are also good insulators, as the compression seal technology fits snugly to the window sash, creating a tight seal which prevents cold air from getting in and warm air escaping. This helps you to save on your energy bills.
