Strong & slimline
The chief virtue of aluminium is its strength. This allows for a slimmer frame, and a greater glass surface area.
Another advantage of aluminium is its durability. Once it’s been powder coated a certain colour, it will be well-protected against rust and discolouration. Moreover, you won’t need to re-apply the finish every few years in the same way that you might with a wooden window.
Being recyclable, aluminium is far more environmentally friendly than uPVC. The energy required to produce an aluminium window is far below the cost of the raw materials, which makes it an excellent choice for those looking to reduce their carbon footprint
