Alumasc’s history documents a steady progression from its early engineering and manufacturing roots to a Group that now supports the built environment through its Building Envelope, Water Management and Housebuilding Product divisions.
Shaped by practical experience and long-standing technical expertise, this heritage continues to shape how we develop our roofing systems. Each solution is grounded in proven performance, guided by robust technical insight and aligned to the needs of the built environment.
Over the decades, we have expanded our roofing portfolio with established brands that address varied requirements across the building envelope. Our systems have been specified on a diverse range of project types, supported by close collaboration with our clients. Third party certification and quality management processes underpin how we develop, assess and refine every product we bring to market.
Today, we combine system design expertise, technical support and a broad range of roofing components. While our offer has evolved, our approach remains consistent: we draw on decades of experience to deliver effective roofing solutions.
