Should You Choose Composite Windows?

wooden window frames

Composite windows are not the first option you might think of for enhancing your home. However, they could be the solution you need. If you live in an older space, you may have timber windows which can wear down quickly.

Over time, the frames can crack, twist and rust due to excess water or high winds. But their authentic look gives your home a touch of classic quality. Because of this, you may want to preserve the style of your windows, and uPVC and aluminium don’t provide that timeless timber look.

Composite windows, though, do. That’s because they use timber in their design, but blend it with more advanced materials. You’ll get uPVC, GRP and a solid timber core, or potentially one that uses insulating foam.

Because of this, you’ll get the look of a wooden window, but without the drawbacks. The uPVC and GRP layers are weather-resistant and scratch-resistant. As a result, they can protect the wood inside the frame from harm, helping the whole design last longer and not need regular maintenance.

Not only that, but composite windows are ideal for traditional homes as well as modern ones. If you live in a listed building or a conservation area, then planning authorities could approve composite windows for your home. Also, they’ll be able to match your living space’s style.

And, with endless customisation options including detailed accessories, bold colours and authentic finishes for the wooden frame, you’ll be able to design a bespoke window that lifts your whole home.

The Benefits of Composite Windows

Composite windows are a modern design with classic appeal. Because of this, you’ll blend old with new seamlessly. The blend of materials creates a denser structure than wood alone, which means you can get better insulation for your home.

The whole window works to trap heat inside it too, thanks to advanced double glazing as standard. As a result, you’ll be able to stay warm in winter, and the slimline frame also allows natural light and warmth to enter your home. That way, you can stay warm while saving on energy bills.

You’ll be able to protect your home in other ways, too. Security is paramount when it comes to your home, and composite windows have the same emphasis on it. These windows are highly durable, thanks to the strength of the composite blend.

Not only that, but the frame can protect internal security hardware from rust and wear. The systems in your window will also be leading designs to give you privacy and peace of mind. For example, a multi-point locking system will ensure nobody can separate the glass from the frame.

Composite windows are also long-lasting designs. While wooden windows can wear away after only a few short years, composite designs take decades to fade. You won’t have to repaint the frame either, as the uPVC and GRP coatings ensure poor weather conditions can’t affect its look.

That means you can invest in bold colours with complete confidence, and you can spend more time enjoying your window, rather than maintaining it. Composite windows last for up to 50 years, longer than uPVC designs!

Composite Windows vs uPVC Windows

So, we’ve already seen how composite windows can outperform wooden designs. However, how do they stack up against modern options? uPVC has become the popular alternative to timber in recent years, and it’s easy to see why.

The material is durable, flexible, versatile and affordable. However, composite windows can best them in almost every area. When it comes to energy efficiency, you’ll get more insulation from a composite frame than a uPVC one. That means you can save more on energy bills over time.

Another benefit of uPVC is its weatherproof design. Composite doors, though, are weatherproof as well, thanks to the fact they use uPVC! Because of this, you’ll get the same amount of protection from the elements. Additionally, though, composite windows have a GRP coating.

GRP is scratch-resistant and much less likely to show visible damage than a uPVC frame. That means you’ll be able to maintain the look of your windows with less effort. And, with a composite window, you’ll get an authentic timber appeal uPVC can’t provide.

Composite Windows vs Aluminium Windows

Another alternative to uPVC is aluminium windows. Aluminium is a precious metal and offers better performance than uPVC. However, that doesn’t mean it can beat a composite design. In terms of performance, these options are roughly similar.

The same goes for security too, and composite windows have the same smart hardware as aluminium designs to keep you safe. Where the difference does lie, however, is in their aesthetics. While aluminium windows are sleek and stylish, composite designs are truly timeless.

You’ll be able to get a classic look with a composite window. Not only that, but you’ll have more ways to customise it. While you can change the colour or finish of an aluminium frame, you can choose different wooden finishes on a composite design.

Because of this, you can get oak, cedar, mahogany or something else entirely to achieve a dream look for your living space. Also, if you live in a listed building or a conservation area, aluminium windows aren’t an option. Composite windows offer the same quality and suit the style of these spaces.

Styles of Composite Windows

Composite windows may look like classic designs. However, you can fit the material to any modern window style. Because of this, you can get the ideal window for you, and you won’t have to make any compromises.

A composite window is versatile, and you can open it in several ways without straining it. Not only that, but you can rely on the material to protect your window’s components. That way, you’ll get a smooth operation every time for decades to come.

Composite Window Styles

Composite Casement Windows

Casement windows are ideal for any home. They have a classic design, using a slimline frame and plenty of double glazing. Because of this, they can open up your home to loads of natural light and warmth, helping you enjoy nature without exposing you to it.

With a composite frame, these windows have an authentic appeal, and you’ll be able to make them last for decades thanks to the durable design. Additionally, you can customise casement windows in thousands of ways, with unique colours, openings and accessories!

Composite Tilt and Turn Windows

Tilt and turn windows are a unique approach for your home. These windows open in several ways, thanks to an innovative mechanism in the centre of the design. Because of this, you can open them outward for stunning fresh air, or inward to make cleaning straightforward.

A composite frame helps you make these windows incredibly secure, too. The frame has superb strength, and it conceals the internal hardware in the design from view. Also, the window always stays locked to the central bar, so you get 24/7 protection.

Composite Sliding Sash Windows

Sliding sash designs have a timeless appeal that’s perfect for composite windows. The window sits flush within the frame, and it has the look of traditional timber joinery. However, it also has a creative vertical slider, meaning you can push the window upward to open it.

The composite frame is a slimline design, meaning it’ll give you gorgeous views of the outside world. Not only that, but the weather-resistant uPVC and GRP protects the wood in the frame, so you get a smooth slide every single time.

Composite Bow & Bay Windows

Bow and bay windows can both create genuine space in your home. Bow windows use multiple panels of double glazing in a subtle curve, while bay designs do the same in a more angled shape. Both, however, extend a wall of your home outward to fit their expansive models.

With a composite frame, you’ll be able to give them the surroundings they should have. These designs are Victorian classics, but a composite structure and double glazing can offer advanced performance to blend old and new effortlessly.
