Aluminium windows – your questions answered

There is no doubt that aluminium windows bring a contemporary flair to your home. With their sleek profile, aluminium windows are ideal for creating an aesthetic statement.

However, despite their contemporary appeal, their remarkable versatility means they are equally at home in period and character properties.

Their inherent strength and rigidity allow them to enhance the architectural style of any home.

Here we answer all your questions about aluminium windows.

The advantages of aluminium windows

Aluminium window frames are robust, secure and long lasting.

Their intrinsic strength also means they provide a more slimline alternative to many other types of frames, achieving a sleek, authentic appearance.

Are aluminium windows better than PVCu windows?

Aluminium is certainly more robust than PVCu and therefore should last for longer. Whether aluminium windows look better than PVCu windows is down to personal taste!

Construction of aluminium windows

How are aluminium windows made?

Aluminium windows are typically made through a process of extrusion. This involves heating aluminium billets (bars) to a specific temperature, and then forcing the softened metal through a shaped opening called a die.

Through this process, window frames, sashes and mullions can be formed with a variety of cross-sections or ‘profiles’.

Can aluminium windows be triple glazed?

Yes, aluminium windows can be triple glazed. In particular, this offers increased sound insulation, making them a popular choice for homes in noisy locations.

Can you have trickle vents on aluminium windows?

Trickle vents are a required feature of all new and replacement windows, to ensure adequate natural ventilation for homes and buildings. Therefore, they are installed within aluminium windows.

Trickle vents are positioned at the upper frame of a window to ensure constant, natural ventilation into the room, even when the window is closed. Read more in our guide to ventilation.

Aesthetic options

Can you have Georgian bars on aluminium windows?

Absolutely! Georgian bars can be installed within aluminium windows to achieve a traditional aesthetic whilst strengthening the window unit.

Contemporary Georgian bars do not hold panes of glass as they are set inside the sealed unit, between the layers of glazing. They emulate traditional styling, whist bringing strength and security to your home.

Can you have astragal bars on aluminium windows?

Yes, astragal bars can also be incorporated into aluminium windows adding character to your home’s façade.

Whereas Georgian bars are an internal bar within the sealed unit, astragal bars are applied externally on the surface of the glass, as well as internally between panes. This gives the authentic impression of the glass being held by the bars.

Can aluminium windows be painted?

Yes, provided you use the correct type of paint. However, we do not recommend painting them as you are unlikely to achieve the same quality of finish as professional powder paint coated aluminium or anodising.

Our aluminium windows are available in any RAL colour, so you will able to find the perfect match for your home.

What is powder coating for aluminium windows?

Powder coating is a method of applying a durable and attractive finish to aluminium window frames. It involves electrostatically spraying dry powder onto the surface, which is then cured under heat to form a protective layer.

What is anodising for aluminium windows?

Anodizing is an electrochemical process that increases the thickness of the natural oxide layer on the surface of aluminium, creating a durable and corrosion-resistant finish.

Sustainability and energy efficiency

Are aluminium windows energy efficient?

Yes. Modern aluminium windows are highly energy efficient.

The insulated frames act as a thermal break, keeping the cold out. Some aluminium windows are designed with a double rebate for additional heat retention and draught elimination. Plus, the slimmer frame means that more of your window is glass, which is an excellent insulator.

Are aluminium windows sustainable?

Yes, aluminium is highly sustainable as it is infinitely recyclable.

Many manufacturers use recycled aluminium in the production of window frames. This saves energy and resources but also reduces the need for mining and production of new aluminium, which has a significant environmental impact.

How long do aluminium windows last? 

We expect aluminium window frames to last at least 25 years, possibly up to 50 years, depending on the weather conditions.

An extra benefit of aluminium is that, when you eventually replace your windows, the frames can be recycled.

Maintaining aluminium windows

What maintenance is required for aluminium windows?

Aluminium windows require minimal maintenance.

Regular cleaning and occasional lubrication of moving parts are typically all that’s needed to keep them in top condition.

How do you clean aluminium windows?

Aluminium windows are very easy to clean.

A mild detergent and water solution with a soft cloth or sponge is all that’s needed. You should avoid abrasive cleaners that could damage the finish.

Do aluminium windows rust?

No, aluminium does not rust, but it can corrode if it is not protected. All our aluminium windows are powder-coated to provide a protective barrier against the elements.

For the ultimate in durability, you can also have the frames anodised. This process increases the surface layer of aluminium oxide; a natural barrier against corrosion.

Do aluminium window frames cause condensation?

Energy efficient double or triple glazing is the best way to reduce internal condensation, along with keeping your home warm and well ventilated. Read more in our guide to window condensation.

Can aluminium windows be repaired?

Yes, many issues with aluminium windows can be repaired, such as replacing seals or hardware. However, extensive damage may require frame replacement.

Aluminium windows and period properties

Do aluminium windows suit a period property?

Absolutely! Despite their modern reputation, aluminium windows complement the character and style of period properties exceptionally well.

Their versatile designs allow for seamless integration that respects the integrity of the building, while providing all the benefits of their strength and energy efficiency.

Crittall windows are a classic example of how modern aluminium windows can emulate classic, period styling.

Can I install aluminium windows on a listed property?

Possibly, yes. In general, local authorities will require a ‘like for like’ window replacement for a listed property.

However, if, for example, your original windows were Crittall steel, then your local authority may be happy for you to replace them with a matching design of aluminium frames.
