Heritage Windows

  • Is your project located in a conservation area and your windows are starting to show signs of wear and tear? Britannia Windows are the local specialists in slimline aluminium windows and woodgrain-effect uPVC.

    Our range of heritage windows is vast. You can explore and select the right window to fit with your project. We offer vertical sliding sash windows and flush casement windows in uPVC and aluminium in the finish you choose, whether that’s classic colours like Chartwell green or our wide range of woodgrain finishes.

What are Heritage windows?

By offering Heritage windows, we mean we are offering you windows that are specially made to replace original windows of period or listed properties. Most listed properties require new windows to match the previous aesthetic of the old ones to maintain the classic look of the house. At Britannia windows, we provide Heritage windows that do not change the personality of your unique project, but rather complement them. Regardless of the style you choose, all our heritage windows have the same modern benefits of our other windows, including double glazing, draught-proofing and high-security locks.

What are timber-alternative windows?

Timber alternative windows are uPVC windows that replicate the look of wood. Unlike timber, you don’t have to regularly sand and paint them to keep them in good nick. These days, uPVC wood finishes are good enough quality to be approved for use in period and listed properties. Containing double glazing, draught-proofing and modern locking systems, your timber alternative windows have the essential contemporary features with the quintessentially charming look. We also have many timber alternative windows which are flush windows. Contact us for further guidance on what windows are best for your period project.

What is a flush window?

Flush windows have a frame which sits flush against the property’s wall. This is an ideal option for period and listed properties as they do not protrude like many modern windows do (which is normally not permitted in older properties). Our selection of uPVC flush casement windows and vertical sash windows contain many finishes and even wood grain choices to help you keep your project’s charm. If you believe you have flush windows and you are planning to replace them, please contact us to talk through your ideas.

Are flush windows more expensive?

Flush windows tend to be more expensive. This is because they involve more precise manufacturing and engineering than normal windows to suitably sit against your property as well as integrating all the features of modern windows. In some cases, listed properties and properties in protected areas are limited to flush windows as their replacement.

Features and benefits

Guarantees you can depend on.

We have built up a great reputation over years of delivering a first class service and excellent products, all from our local, no nonsense all-about-you company.

From characteristic country cottages to contemporary town houses, we’re confident that our products will offer a style and finish to truly transform your project. Through constant innovation the quality, durability and security of our products is genuinely second to none. As a local company we are proud to offer British Standards BS7412/PAS24 for enhanced security.

We refuse to compromise on quality

Our windows are made from British Made, high quality MarinespecTM components, with up to 25 years anti corrosion. They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

State of the art fabrication for best quality

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices. Our loyal factory workers are well trained and take pride in their work, they really care about quality.  Our machines are maintained according to a rigorous servicing regime to keep them in top condition.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our projects energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your project warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.

The styles available are endless and the choices to suit your project are bigger than ever before. Traditional, contemporary or modern; our versatile window and door designs will create the look you want to complement and enhance your project.
