Energy Efficiency

energy-efficencyPVC-U is an insulating material. Using multi-chambered systems, thermal-wall technology and thermal inserts, allows us to build windows and doors with excellent insulating and thermal-performance characteristics. In fact, we’ve made it part of our process to ensure that energy efficiency is always part of our design.

Every Spectus product is designed to comply easily with the requirements of the Building Regulations. Window Energy Ratings from ‘A+’ to ‘C’ are available, depending upon glazing. Our systems are designed to incorporate either double or triple glazing and when appropriately glazed, our windows can achieve U-values as low as 0.8W/(m2K).
