Aluminium Advantages


Are you considering purchasing new aluminium windows or doors? There are many advantages attached to doing so. More and more people have been investing in aluminium windows and doors for their homes and businesses over recent years, citing factors such as the reduced level of maintenance they require and the greater number of colour options. Advancements in technology have made aluminium windows and doors more efficient than ever, with the solutions taking vast prominence over plastic alternatives.


Greater aesthetics


One of the reasons aluminium windows and doors have become so popular is their visual quality. Aluminium offers slim sight lines as well as extra strength and greater defence from the elements, meaning worries about warping and rotting can be largely forgotten. Improvements in polyamide technology have boosted thermal insulation levels and have enabled customers to obtain a dual colour finish. Aluminium can make your windows and doors more energy-efficient, more eco-friendly and help you save a substantial amount on your fuel bills as a result, whilst also improving the aesthetics of your home.


Slimmer profiles


Many people regard PVC profiles as being too bulky, which means the slim profiles of aluminium windows and doors have become highly desirable, enabling people to make the most of the views available to them. Aluminium also has a greater lifespan than uPVC, offering 20-30 years to uPVC’s 15-20. Its high strength-to-weight ratio also means your windows and doors shouldn’t dent so easily. In the past, aluminium was mainly associated with commercial buildings such as schools and council offices, but it is now helping to form the windows and doors of many residential customers. Aluminium is also fully sustainable, 100% recyclable and non-toxic. Recycling only costs 5% of the energy used to manufacture it.
