Energy Efficiency

PVC-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.

• 3mm wall thickness
• 5 chamber system
• Innovative AEROFRAME^TM thermal-wall technology in our Fully Reversible system
• Recycled composite inserts that improve insulation
• Effective seals and draught proofing.

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).
