The Advantages of uPVC and timber windows

Sustainable windows with excellent energy ratings

Windows lose and gain heat, in a process called ‘heat transfer’. This heat transfer is expressed in U-values. The lower the U-value, the more insulated the window is and the less heat is transferred. Timber and uPVC have low U-values because they are poor conductors of heat, meaning your house stays cool in summer and warm in winter.

According to the Windows Energy Rating Scheme, uPVC and timber windows provide a much higher level of energy efficiency compared to standard aluminium window frames. By keeping hot air outside during the summer months and warm air inside during winter, uPVC and timber window frames will help dramatically cut your power bill and improve the sustainability of your property.
