Comparision uPVC Windows vs Aluminium Windows

Window Aesthetics

Your property’s style plays a large role in your choice of windows. Several factors need to be taken into consideration, the age of the property, the area where it is located and the style of the house. You want windows that best complement the style of your home. If your home has a modern or contemporary style, aluminium windows deliver a modern aesthetic and will fit with the style of your home. uPVC windows have more of a classic look which doesn’t quite have the same effect. If your home is more traditional, a listed building or in a conservation area, UPVC windows have a simple aesthetic that can be used. Aluminium could also be used, as it is possible to finish aluminium frames in a wide range of different colours or to mimic other materials like wood.

Window Maintenance

When you compare the maintenance needed for uPVC and aluminium windows there are both similarities and differences. Both materials need minimum maintenance and can be easily cleaned using soapy water. Neither window type is susceptible to rot, or insect infestation. They are also unsusceptible to corrosion and neither needs to be treated to make them waterproof. Aluminium windows have a much longer lifespan in comparison to uPVC windows which warp over time. uPVC windows have a life of around 20-30 years, whereas aluminium windows can easily last for 50 years and more, without maintenance.

Strength

When it comes to comparing the strength of the 2 different window materials, we have an obvious winner. uPVC windows are reasonably strong, but they can’t compete with the strength of aluminium. Aluminium has a high strength-to-weight ratio, which means you can have incredibly light, stylish frames that are super strong! The low density of aluminium is a prized property as it means that lightweight products can be produced that have super strength. Being lightweight also means that aluminium windows are easier to install.

Durability

uPVC windows were originally introduced 30-40 years ago, they have always been popular and have many advantages as we have already seen. The windows are durable and need little maintenance but only for 20-30 years. After this time they begin to degrade and often warp and require replacing. In comparison, aluminium windows are durable, strong and have a lifespan of 50 years and more. A high force is required in order to break or dent aluminium window frames, which means that they are durable in extreme weather conditions. Aluminium resists wear and tear over long periods of time, and direct sunlight and is unaffected by extreme temperature changes. Aluminium frames are also treated by anodising or painting before they are installed, which means that the window frames do not discolour easily. They are also unaffected by pollutants in the environment including carbon monoxide and carbon dioxide.

Security

As both materials are durable, they are difficult to break and are both secure. More so compared to wooden windows which can be susceptible to rot or insect infection, this can drastically reduce their security and allow for forced entry. The level of security of a window relies more upon the locks or other security measures that are installed or added. Although uPVC tends to degrade over time after 20-30 years you will need to replace them in order to continue being secure.

Energy efficiency

The energy efficiency of a window comes down to the thermal insulating ability of the window material and also the glass that is installed within the frame. In the past uPVC was considered to be a better thermal insulator compared to aluminium. However, developments in technology have allowed aluminium to rise to the challenge. Now, aluminium frames contain thermal breaks which prevent too much heat from escaping, this makes aluminium as energy efficient as uPVC.
