Aluminium Windows

Aluminium windows, one with trickle vent and one with astragal barsAluminium has evolved over the years, becoming a sought-after window material thanks to its sleek, sophisticated looks. Multiple benefits for homeowners are making aluminium an increasingly popular choice for new windows, and converting more installers to aluminium installation in the process.

Aluminium windows are slimmer than uPVC and timber and homeowners are sold on the barely visible sightlines. Other selling points include aluminium’s strength and security, polyamide thermal breaking technology for energy efficiency and its long life and low maintenance.
