Composite windows combine the best features of timber and aluminium to deliver a truly top of the range window.

What are Composite Windows?

These windows combine the attractive looks and effective insulation of a timber window inside, but have aluminium cladding on the exterior for easier maintenance and durability. So it’s a durable window with a low maintenance finish that still offers the charm of wood internally. If you are looking for high performance, attractive and long lasting windows, composite frames could be the answer.

Benefits of Composite Windows

The hybrid nature of composite windows gives you the best of both worlds in terms of performance, reliability, aesthetics and thermal properties. The aluminium cladding offers durability and requires lower maintenance than traditional full timber windows.

Longer Lasting

Composite windows are more durable and have a much longer lifetime than uPVC windows. A life cycle of 40 years has been suggested which easily beats the widely recognised 25-35 year lifespan of uPVC units.

Excellent Insulation

The insulation properties of the timber interior means you keep more of your heating inside giving you a more comfortable home. In fact composite windows are particularly popular in cold climates such as Sweden and Canada where, as you can imagine, insulation is a must!

Energy Savings

If you’re losing less heat through your windows you should be able to reduce how much you run your heating. Using your heating less means you’ll need to buy less fuel and using less fuel will lower your home’s carbon footprint.

Strong and Reliable

Both timber and aluminium are renowned for their strength so the combination of these materials in one frame results in a very strong window which could improve your home’s security.

Low Maintenance

Although timber has a reputation for needing maintenance, in composite frames the timber is on the interior so its not exposed to the outside weather. The exterior is aluminium which requires little to no maintenance.

Both aluminium and timber are recyclable materials which, in addition to the energy savings they deliver, makes composite windows a far more environmentally friendly choice than uPVC.

Attractive and Flexible Designs

Composite windows are available in a wide range of colours, sizes and styles making it easy for homeowners to find the perfect windows for their home. Most manufacturers offer a RAL colour matching service for aluminium-clad composite windows, so you can choose from a bold colour to make your windows stand out as a key feature of the façade or a more muted shade to blend in.

Gloss, matt and satin powder-coated finishes are all available including anodised aluminium. Internally, the wood can be stained, lacquered or painted to suit your tastes. Composite windows are available in all types of styles like bay and cottage and opening formats including casement, sash, dual turn and tilt and turn.

Cons of Composite Windows

There’s only really one downside to composite windows, and that’s the cost. They’re at the top end of the price range and so may not be as affordable as uPVC windows.

Composite Windows vs uPVC Windows

uPVC windows are often a popular choice as they’re the cheapest type of frames you can buy in terms of upfront costs. However, uPVC windows have a much shorter life span and may need to be replaced after 20 – 30 years while, with proper maintenance, composite windows can last 50-60 years.

Composite windows will require maintenance which will cost money, but uPVC windows are not maintenance free; they require care, can can warp and discolour over time and sometimes they can be difficult to repair.
And in terms of ongoing reduced heating bills and energy savings, the composite windows are far better at insulation and so keep more of your heat indoors.

Composite Window Prices

Generally, composite windows sit at the upper end of the pricing spectrum. Timber is a costly material and then the additional aluminium cladding adds to the cost again. To install double glazed composite windows throughout a house could cost in the region of £10,000 and £25,000. As you’d expect, this cost will increase by around 25% for triple glazing.

However, while the upfront cost of composite windows is likely to be higher than a material like uPVC, it’s important to consider the long term. Composite windows are more durable than uPVC and require almost no maintenance. In fact, some studies have suggested that composite windows could be 23-35% cheaper than uPVC over a 60 year period.
