Heritage Windows

  • If you live in a conservation area and have been itching to replace worn and rattling windows for an insulative and non-draughty replacement, we can help. We are the local experts in slimline aluminium doors and windows and replacement steel windows (including the market-leading window brand Crittal®). Choose from a variety of textured finishes and colours to complement the character of your period property.

    We’re here to help you get windows you love that are within the realms of conservation area and listed building restrictions. Heritage windows can now be both high performing and aesthetic; there’s no need to compromise! 

    Our diverse selection of heritage windows means you can choose the perfect fit for the style of your home. We can offer vertical sliding sash windows in UPVC and in any finish you wish. Our woodgrain finishes (which are almost identical to real wood) are highly aesthetic but don’t require the rigorous upkeep of timber frames.

What are heritage windows?

Our heritage windows are specifically designed to replace those that were originally installed in listed and period homes and buildings. In the case of many listed buildings, the owner is required to replace the original windows with a style that will preserve the aesthetic of the property. Our windows are state-of-the-art, equipped with features such as draught-proofing and double glazing, whilst also being traditional and aesthetically pleasing. Here at Britannia, we’ve found that because heritage windows possess the style of traditional windows with the benefits of modern ones, they’re consistently popular.    

What are timber-alternative windows?

Timber alternative windows give a wooden and rustic look but don’t require maintenance such as painting and sanding.  Thanks to modern innovation, they’re frequently sold as Heritage windows because the PVCu wood finishes are of such high quality; this means they are considered a viable option for listed and period buildings. Have the benefit of modern locking systems and draught-proofing, without compromising on traditional charm and character. You can even choose timber alternative flush windows; get in touch today to find out more or visit our local Hayle showroom to see our high-quality products in person.

What is a flush window?

Timeless and elegant, flush windows sit flush within the frame, creating a flat surface on the outside wall of a property. Contemporary window designs tend to protrude beyond the main frame of a property and are generally forbidden for properties that are period or listed. We manufacture vertical sash and PVCu flush windows that come in a range of finishes, including wood grain colours to preserve your house’s traditional aesthetic. Contact us if you’re looking to replace a set of flush windows – we look forward to helping you select the perfect style!

Are flush windows expensive?

Flush windows are typically more costly than those which jut beyond your home’s main walls, as they require a more advanced degree of engineering to manufacture. It’s possible that if you live in a conservation property or area, you could be limited to flush windows as replacements. This said, you will get the benefits of having modern windows which have great insulation, better security and less upkeep, while also having a beautiful-looking window.  

We can’t wait to help you decide on the ideal choice of window that suits you and your home.

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 home. 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 homes energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your home 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.
