Aluminium windows have long had a bad reputation, with a lingering negative reputation that makes homeowners think twice when choosing new windows.
However, what if we told you aluminium windows today are hugely different from the single-pane, thermally inefficient frames of the 1970s and 80s?
Aluminium is becoming popular across the UK as a material of choice for window frames. Architects and home builders alike are choosing aluminium frames for new projects, and they’re quickly becoming a stylish, chic choice for new homes.
Here at Seal-lite, we’re fans of Aluminium frames, which is why we’ve put together the following guide to separate fact from fiction and set the record straight on why modern aluminium frames are an excellent choice for your home.
They Are Cold and Inefficient
This is one of the most common myths surrounding aluminium window frames, rooted in the history of older, inefficient aluminium windows. Metal is, by nature, conductive, so older frames without insulation were indeed poor insulators.
However, new aluminium frames are made with thermal break technology inside. This thermal break is highly insulating, made with non-metallic materials inserted between the internal and external sections of the aluminium frame. This acts as a barrier to prevent heat from escaping from the warm inner frame to the cold outer frame, and stops the cold from getting in.
They’re Prone To Condensation
Another common myth, stemming from the older types of aluminium windows, is that they are prone to condensation. In the past, when the cold external frame was directly connected to the inside of your home, the interior surface temperature could quickly drop below the room’s air temperature, causing condensation to build up.
In reality, modern thermal breaks in modern aluminium windows isolate the internal frame from the cold of the external side of the window, keeping the inner surface warm.
Any time condensation occurs, it’ll be down to high indoor humidity, such as a lack of ventilation, rather than the thermal performance of the window itself.
They Aren’t Durable
Often, people believe that aluminium window frames can corrode or rust, as they are made of metal and exposed to the elements.
Aluminium does not contain iron. This means that it cannot rust. When exposed to the elements, aluminium will form a thin, transparent layer of aluminium oxide. This aluminium oxide is protective and hard, and actually prevents further corrosion.
Modern aluminium frames are also coated in powder coating, offering further resistance to salt, UV rays and general weathering. This makes them an excellent option for properties in coastal areas.
They Aren’t Aesthetically Pleasing
Aluminium windows look excellent on properties of all ages. Commonly, they’re thought of as quite a modern addition; however, with their sleek, minimalist design, they can suit both contemporary and traditional homes.
As aluminium is so strong, these windows can have much slimmer frames, creating a clean line and allowing for more glass, maximising the natural light brought into your home.
They can also be finished in a huge variety of colours and finishes, to suit your home’s existing look.
They Aren’t Environmentally Friendly
The initial production of aluminium often leads people to assume that these windows aren’t environmentally friendly.
However, aluminium can be recycled indefinitely without losing any strength or quality, making it a truly ‘circular’ material. The recycling process of aluminium also requires up to 95% less energy than producing new aluminium. Therefore, many window companies will actively choose to use recycled aluminium to make the frames.
They’re Tough To Maintain
As these windows are made from metal, it’s commonly thought that the maintenance process must be complicated or require a significant amount of DIY knowledge.
They are actually incredibly easy to maintain, requiring only occasional cleaning with lukewarm water and a mild detergent. Unlike wooden frames, which will require sanding and repairing, aluminium is durable and resistant to corrosion, rot and warping. Their sleek appearance can last for decades, all with minimal input.
They’re Only For Commercial Buildings
For many years, aluminium windows were seen as only for use in commercial buildings, due to their strength and durability. However, this strength allows for larger windows and slim frames, creating a modern and sleek aesthetic that can be tailored to fit a variety of architectural styles, making it perfect for both new construction projects and renovations.
They’re Expensive
Aluminium windows will typically have a higher initial price when compared to other window types; however, they are an excellent long-term investment for your home.
First of all, they have an average lifespan of 30 to 40 years, and they require little to no maintenance costs.
Thanks to their clean lines and modern aesthetic, these windows can also increase your property’s overall value, not to mention the proven increase in energy efficiency, which is often valued highly by buyers.
With this improved thermal performance, these windows have very low U-values and excellent energy efficiency, to provide noticeable savings on your heating bills throughout the year.
