Window energy ratings in Wales are measured on a scale from A++ (meaning most efficient) to G (meaning least efficient). An A-Rated window meets strict standards and regulations for energy efficiency, helping to reduce heat loss and improve comfort in your home.
Up to 70% less heat loss can be achieved by replacing your old single glazing or poorly performing double glazing with modern A-rated energy efficient windows. The energy/cost savings can be substantial.
Learn about the benefits of energy-efficient windows, how they work, and how to choose the best one for your home.
Double glazed windows have energy efficiency ratings from A to G. Our energy efficient windows are of the highest quality and are fitted by professionals.

The first thing to highlight is that you can reduce heat loss by as much as 70% when you replace old single glazed windows or cheap double glazing with intelligent A-rated energy efficient windows.
This simple scheme controlled by the BFRC (British Fenestration Rating Council) allows windows that have been put through a rigorous testing process to display a rating from A-G with an A rating being the best. The main benefits of installing energy rated windows are
Why Should I Have BFRC Energy Rated Windows? In the current climate and with the cost of living dramatically increasing, being energy efficient is more important than ever.

Furthermore, visual representations like the one above help us fully grasp the concept of Efficient Energy Rated Windows.
How ENERGY STAR windows work. What energy performance ratings really mean.Use the ENERGY STAR Climate Zone Map to find windows rated for your region. 2. Choose the Right Frame. Vinyl: Budget-friendly and energy efficient. Fiberglass: Durable and weather-resistant.
Energy efficiency is not just about the glass. The frame matters too. Fiberglass frames are among the most efficient and durable options available.This is why many efficient windows are rated according to regional energy zones.
