As the largest privately owned fenestration systems house in the UK, we design, manufacture and supply innovative and high-performance aluminium windows, doors and curtain wall systems for use on projects across the sectors. With a strong focus on supply chain collaboration, we recognise the value of relationships and work closely with both our fabricators and clients to deliver fenestration solutions that perform as well as they look. With a state-of-the-art manufacturing facility in South Yorkshire, which includes our own in-house powder coating paint line, we have additional distribution centres in Scotland and Wales and have worked on projects across the UK.
