Environmentally Friendly Aluminium Shop Front Doors
Known as the green metal, aluminium is an excellent sustainable alternative to other materials, occurring naturally in the ground and requiring less energy to produce compared to traditional timber frames. As aluminium is very durable and strong, it typically lasts for up to 30 years. 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.
