UPVC is one of our most common and reliable plastics. It’s also an extremely smart material that allows significant energy savings without extravagantinvestments or complicated technology. UPVC is a low conductor of heat. This means it helps retain the heat inside buildings and helps keep the cold out and vice versa. Additionally, UPVC windows have excellent weather seals which enhance this beneficial effect. In its energy saving capability UPVC Windows easilyoutmatch the competition. The thermal properties of PVC-U have been developed further by the design of window profiles which allow multiple chambers to trap air and to create a thermal barrier. Couple this with the latest technological advances in double glazing materials and you create some of the most costeffective energy saving windows available today.
