About from company website
Treforest Glass has been manufacturing and supplying high-quality sealed units to the industry and public for over 30 years. In that time, we have gained significant experience in producing high-performance units to satisfy all sorts of requirements, from energy efficiency and low noise levels to low-sightline heritage units. We deliver our products all over the UK via our own fleet of vans or courier services.
Originally based in Treforest, we moved to a state-of-the-art factory in Tonyrefail in 2018, installing a toughening plant and advanced machinery to become fully self-sufficient. We are committed to supplying customers on time and at a competitive price while maintaining quality standards. We also take our social responsibility seriously, installing solar panels in 2020 to provide a significant percentage of our electricity demand and recycling materials.
Our experienced fitting team covers the South Wales area, offering free surveys and quotations for a range of services including replacement units, splashbacks, mirrors, shopfronts, and secondary glazing. We offer a wide range of glass types, including acoustic, energy-efficient, solar control, easy-clean, and heritage slim low sight line units, as well as decorative products.
