A+14 energy rated Georgian and leaded windows
All windows are rated using the WER (Window Energy Rating) scale. The scale runs from A-G, with A and above the highest performing. The WER is based on the window’s U-value, solar heat gain value, and overall insulating capacity. The quality of the glazing, frame, and installation all affect the window’s performance.
Georgian and leaded windows from Majestic Designs feature warm edge thermal spacer bars and argon gas sealed units. This helps them to achieve such high WER scores. They are BBA (British Board of Agrément) accredited for their excellent durability, energy efficiency, and weather resistance.
