What Makes Them Different?

There are many differences between uPVC and aluminium, and homeowners across the UK all have individual tastes and preferences, making it essential to understand the best choice when installing their new windows, doors, and conservatories.

Strength & Durability

One of the most notable differences between the two materials is that aluminium is a metal, and uPVC is a type of plastic. While both materials have very high durability, aluminium has no need for reinforcements. 

Colour Options

While both uPVC and aluminium can be in coloured profile sections, the Aluminium has a wider range of colours available to enhance any residential or commercial property, such as schools, shops or hospitals. 

Unique Designs

As these materials are crafted using different methods and have their own unique textures and properties, they typically end up having designs that provide their own distinctive aesthetic. 

What Do They Have In Common?

Surprisingly, uPVC and aluminium have many similarities, making it easier to determine which is best for your customer’s property. Our uPVC windows and the Alitherm 400 windows are a 70mm system and are internally glazed. 

Thermally Broken Profiles

A thermally broken profile has a specially designed hidden hollow chamber containing a small amount of material that is good at containing heat. Both uPVC and aluminium frames are built with profiles in order to enhance their energy efficiency, by working in tandem with bespoke double glazing. 

At Connaught Windows, our uPVC windows come multi chambered profiles as standard and highly efficient double glazing with the ability to upgrade to our ‘A’ rating containing Argon gas.

Sustainable Construction

While most people would assume that uPVC can’t be sustainable due to it being a type of plastic, uPVC can actually be collected and melted down to be used again within brand new profiles and products. Aluminium is also very easy to melt down and reforge into new windows and doors just like almost any other metal. They can also both last for decades with only minimal upkeep, as neither material will absorb moisture or decay.
