Environmentally Friendly Shop Front Doors
Known as the green metal, aluminium occurs naturally in the ground and requires less energy to produce compared to traditional timber frames. As aluminium is very durable and strong, it will typically last for up to 30 years, and once it reaches the end of its lifecycle, it can be recycled indefinitely.
All our commercial aluminium doors have been sourced and manufactured using sustainable materials. Learn more about sustainability at Sternfenster here.
