Prior Products are BFRC approved manufacturers and installers, offering high specification 'A' and 'C' rated energy efficient windows. We are also members of the Planitherm Installers Network, who regulate quality, security, u-values and building regulations in glazing products. Prior Products leads the way in producing high level specifications on all of our products, whilst utilising all the latest technology in-house to create the most advanced secure, maintenance free windows, doors and conservatories. Our energy rated PVCu (also known as uPVC) windows will reduce energy bills, not only saving you money, but also reducing your carbon footprint. All technical specifications on our uPVC windows, doors, vertical sliders, secondary and tilt/turn products can be viewed on our website. Our newly expanded range of composite doors can also be seen, showing all the different styles and glass options. Our PVCu casement window and door range is now available in a coloured grained finish to meet any commercial or domestic home improvement requirements. This helps us to supply windows and doors that are sympathetic to the local environment, even in conservation areas.
