Energy Saving Film

Energy Saving Window Film for Commercial Offices - Hitchin, Herts & UK


Window film is an ideal choice for increasing the energy efficiency of your building, while contributing to cost savings within your heating budget and the wider environment.

Commercial interior designers have been promoting the use of energy saving window film for many years. Installing window film enables energy efficiency while making potentially huge savings on heat control, within retail outlets and offices.

Did you know energy saving window film:

  • Reduces the amount of heat loss through the glass during the winter
  • Reduces the amount of heat build up during summer
  • Reduces air condition running and maintenance costs
  • Helps control the temperature within your commercial premises
  • Reduces your company’s carbon emissions and footprint
  • Provides a payback within 3 to 5 years, depending on film type and AC costs


Solar control window film works by reflecting solar energy and UV rays before they enter your commercial establishment. With less reliance on air conditioning and cooling systems, you can substantially reduce your energy usage and costs.



What are the potential energy savings for your company?  

Prism will:

  • Produce energy saving reports on buildings to show savings
  • Provide a free energy survey that will show you how much money can be saved, once window film is installed.
  • Provide payback periods to show how cost-effective the window film can be


Prism can install a range of window films that can reject up to 79% of solar energy and 99% of UV rays:

Reducing costs with energy efficient window film


Film is applied to your window glass directly, forming a barrier to solar energy. This is cheaper than replacing your glass and is far more effective than blinds.

Prism provide a variety of window films with different metals, layers, base layers and adhesives, so before you decide on which type may be best for you, please contact us to discuss the merits of each for your commercial operation.
