Energy PLUS Glass is a new generation of energy saving window glass that uses an advanced coating to retain more internal heat and to absorb free energy from natural daylight, designed for use in a double glazed unit. That means lower energy bills compared to standard double glazing but for less cost.

Using the latest technology Energy PLUS Glass has a unique combination of metallic layers, which reflect heat back into a room, to keep heat within a building. At the same time maximizing the amount of natural light coming in. As more heat is retained, it means less is required to warm up the home to the desired ambient temperature, in turn lowering energy consumption.

There are a number of reasons why you should have installed Energy PLUS Glass in your windows. Firstly, Government Building Regulations requires us to use energy efficient products that help to reduce CO2 emission and protect the environment. is the most energy efficient window glass available. Using is an easy and efficient way of complying with these regulations whilst offering a number of other benefits:

  • Free Solar Gain – Energy PLUS Glass uses advanced coating technology to capture free energy from natural daylight to help heat the home.
  • Thermal Insulation – The advanced coating reflects heat back into the room, meaning less energy is needed to heat the home to the desired temperature.
  • Haze & Tint Free Windows – Energy PLUS Glass maximizes the amount of natural light into the home, without the haze or tint effects associated with older double glazed windows.
  • Eliminate Condensation – Energy PLUS Glass helps to virtually eliminate internal condensation, reducing draughts and cold spots in and around the windows.

Of course all old, uncoated, double glazing offers a limited level of heat retention. However, Building Regulations now state that an energy efficient window glass must be used in all replacement windows and a double glazed unit containing Energy PLUS Glass is on average 60% more thermally efficient than standard non-coated double glazing.

Yes, the coating is permanent and hermetically sealed with the glass unit so will last the lifetime of the window

The glass has a very thin, transparent metallic coating that reflects heat back into the room, rather than allowing it to escape through the windows. At the same time it allows heat from the sun to pass through the glass to warm the room, meaning it takes less energy to maintain a warm, comfortable home.

Yes, the performance of Energy PLUS Glass meets the requirements of class C of European Standards BS EN 1096 and carries the relevant CE Marking.
