Why Choose PVC-U?

Energy-Efficiency
Much of the heat loss from a building occurs through glazing. The five-chamber design of certain PVC-U units enables your home to enjoy greater thermal efficiency.

Your new window and door systems can be made more energy-efficient to achieve a BFRC energy rating from C to A (the highest possible rating) depending on the specification you choose, and keep your home warmer and draught-free, as well as saving you money on heating bills.
