Aluminium vs uPVC – Which is Better?


Aluminium windows and doors have been growing in popularity over recent years. This lightweight yet strong material has many benefits, and it is no surprise that it has become a favourite amongst modern homeowners. Aluminium is a malleable metal and can be easily shaped into different frame designs.

The sleek finish of aluminium makes it a popular choice for contemporary homes. Unlike timber alternatives, aluminium windows and doors do not need to be primed and treated before painting. This weather resistant and durable material will keep its shape and colour for several decades. Investing in aluminium windows and doors will ensure your home continues to look its best for many years to come.

Aluminium home improvements don’t just provide homes with a stunning appearance. This strong material is lightweight. Meaning profiles can feature both slim frames and large panes of glazing. When you choose an aluminium installation, you can opt for large windows with sleek sightlines. With these profiles installed, your home will achieve maximum levels of natural light, and you can enjoy unobstructed views of your surroundings.

Often featuring a thermally-broken design, aluminium windows and doors can boost a property’s energy efficiency. The insulated frames prevent heat loss and effectively lock warm air inside. Aluminium also offers additional security for your home, thanks to its natural strength.

Unplasticized Polyvinyl Chloride, more commonly known as uPVC, is regularly used in the manufacturing of windows and doors. uPVC home improvement products have been popular for several decades, and the majority of UK homes have uPVC windows installed. Unlike traditional PVC, uPVC has not been softened with plasticizers. This means uPVC keeps its shape and is less flexible than PVC. uPVC is a versatile material and is used to create multiple window and door profiles.

uPVC windows and doors are available in white as standard, but the frames can be customised in a range of different colours. These windows are a popular alternative to damaged or outdated timber frames. uPVC can be coated with a woodgrain foil finish, achieving a wood-like appearance with none of the deterioration issues associated with traditional timber.

With uPVC windows installed, properties will benefit from increased energy efficiency and security. The window frames add reliable insulation to homes and keep their factory fresh appearance for several years. Unlike timber alternatives, uPVC windows and doors will not suffer weather damage. With these durable installations, homeowners have no need to worry about rot issues, repainting or expensive repairs in the future.

When you upgrade to uPVC windows and doors, your property will experience improved thermal performance, protection and kerb appeal.

• Contemporary aluminium profiles are often more expensive than uPVC models. The extra strength and long term performance of aluminium comes with a higher price tag.

• uPVC and aluminium are both energy efficient, but the latter can offer enhanced property insulation.

• Aluminium is stronger than uPVC and can support the weight of larger glazing panels. If you want large windows with slim frames, lightweight aluminium is the best option.
