PLANITHERM - Reduce your energy bills

We know we live in hard times that are on the verge of getting harder. Reduce your energy bills by installing Planitherm – proven to be the most energy efficient window glass available in the UK.

What Is Energy Efficient Glass?

Planitherm energy efficient glass products help improve the window energy ratings of your glass and make your more comfortable. Resulting in lighter, brighter, warmer and more energy efficient s thanks to the advanced thermal insulation which is 3 times more efficient than single glazed units and at least 25% more efficient than most currently installed double glazing.

  • Free Solar Heat Gain - advanced coating technology allows you to capture free energy from natural daylight to help heat your home
  • Improved Thermal Insulation - advanced coating reflects heat back into the room, meaning less energy is needed to heat your home
  • Improved Energy Efficiency – the reduced need for heating helps to save energy whilst saving you money on your heating bills
  • Eliminate Condensation - the inner surface of the glass stays warmer to virtually eliminate internal condensation, reduce draughts and cold spots
How it works?

Planitherm products have a transparent metallic coating that reflects heat from radiators or fires back into the room, rather than allowing it to escape through the windows.At the same time it allows free heat and light from the sun (known as passive solar heat gain) to pass through the glass, warming your and further contributing to the energy efficiency of your windows. The coating is permanent and hermetically sealed within the glass unit so will last the lifetime of the window.
