What are heritage windows?

Heritage windows are the perfect solution for those looking to replace or install windows in listed or period properties. By law, if you own a listed building, you are required to maintain the original look of the building as closely as possible, heritage windows are designed with this in mind to be almost like-for-like units. Over time, heritage windows have developed and evolved to provide the high performance that modern windows come with, whilst maintaining a traditional appearance that is faithful to the building’s original style.

Are heritage windows uPVC?

While many listed buildings may have windows made from timber or similar, these come with their own set of complex challenges in the modern day such as thermal efficiency and safety. Heritage windows can be made from vacuum double-glazing which provides much higher levels of security, are more energy-efficient and come with an A+ energy rating.


For over 20 years we have seen our customers enjoy the many benefits that bay windows provide first-hand.
Here’s why they are so popular among many of our customers…

Energy Efficient

While the original windows on listed buildings may not have the necessary protection to keep out unwanted drafts, heritage windows use modern coated glass and advanced double glazing to keep rooms warmer for longer, improving the thermal efficiency of your property as well as reducing your energy bills and saving you money!


Our heritage windows are designed to be highly waterproof and don’t absorb water or moisture in the ways that original windows might. As they are non-porous and non-corrosive, they also won’t expand or contract over time and will maintain their structure and functionality for years.

Durable & Resilient

Heritage windows are often made from uPVC double-glazing which is highly durable and resilient and can last up to 35 years if maintained properly. Our uPVC windows are manufactured, supplied, and installed to exceptionally high standards using high-quality materials.

Traditional & Authentic Appearance

The very nature of heritage windows is to preserve the original features of a property as closely as possible, therefore they go a long way in maintaining a traditional and authentic appearance for many listed and period properties. Furthermore, these kinds of windows are great at adding much-desired kerb appeal to your home.

Add Value to Your Home

If you’ve been wondering ‘do heritage windows increase home value?’ then we can say with certainty that they do. Heritage windows are seen as an attractive feature to many potential buyers as they are faithful to the building’s original design, combining this with modern technologies and advancements for better overall performance.

What is vacuum double-glazing?

Vacuum double-glazing is a great alternative to double-glazing in heritage windows. It is designed to give the appearance of traditional single-glazed windows that would have originally been installed in listed buildings, but instead of having gas in the space between panes (as with double-glazing), it has a vacuum. This design also allows for the window to be visually slimmer than double-glazing, and therefore more in line with traditional design.
