We’re pleased to launch the new Westcoast website, with all the information our commercial clients need to spec our high performance bespoke composite windows.

Westcoast supplies high performance composite windows for commercial developments. Our philosophy is to build windows of the highest quality, which continues through to our sales, design and production, all the way to delivery on site.

The needs of commercial buildings have evolved over the years, with new developments and refurbishments demanding a greater emphasis on sustainability and environmental performance.

Our UK-based team partner with well-respected contractors, architects and developers to assist in the planning of their projects, offer solutions to potential challenges and provide specification information and estimates to meet their requirements.
