Energy Saving Window Films

Improving Building Energy Efficiency

Making the right decisions about energy efficiency improvements can be challenging. Energy efficiency professionals prioritise building systems upgrades such as lighting and HAVC controls. But building envelopes can also be easily upgraded economically and effectively with our carbon negative solar control window films. Offering one of the best opportunities for a speedy ROI and creating a comfortable working environment by reducing hots pots and decrease the need for air conditioning.

Over 30% of a building’s average cooling load is due to solar heat gain passing through the glazing. By applying our solar control window film to your existing glazing, you can control the amount of solar gain heat entering. This not only reduces heat build-up, temperature fluctuations and hot spots, but also cuts HVAC running cost dramatically. Helping to lower carbon emissions, saving money on fuel and HVAC maintenance costs.

Due to buildings having such a large source of carbon emissions, many building managers are concerned with reducing their carbon footprint.

UK Window Films solar control window films are both carbon-effective and cost-effective, reducing a building’s carbon footprint more effectively and for less money than new windows. Some of our solar control window films are proven to be carbon negative within one year of installation.


  •  One square meter of a low-e wood window, the type with the smallest carbon footprint, has a carbon cost of 444 kilograms. The carbon cost of our carbon negative window film is less than one kilogram per square meter.
  •  Our carbon negative window film saves 100 times more GHG emissions from entering the atmosphere than is used and/or created during its manufacture.

UK Window Films deliver an extensive range of energy saving carbon neutral window films. Whether you need a speedy return on your investment, looking at long term energy conservation or enhance the functionality of a building, UK Window Films will have a film for your needs.

Avoid high energy bills with Low-E window films

With rising energy bills and winter just around the corner, this usually means turning the heating up and an increase in energy bills. Conserving heat should be high on the agenda.

For most homes and commercial buildings. Cavity wall and roof insulation is often regarded as the most sensible investment to make. What about the glass in your windows?

Some outside walls of an office or a home often consist of more glass than brick walls or cladding. Untreated glass will be your weakest point for heat loss. Closing curtains or blinds may help to retain some of the heat, but this spoils your view.
Window insulation should be seen as the number one priority for energy-conscious companies and home owners this winter. The problem is that most people do not know how to go about insulating their windows.

The most logical step, many believe, is to install low-emissivity (low-e) glazing. By absorbing a significant amount of energy created by heating systems inside the building, low-e glazing is extremely effective at preventing heat loss and keeping energy bills down as a result. However, low-e glazing requires new windows to be installed, a very large upheaval and an expensive investment that will make a significant impact to your pocket.

Fortunately there is a product which will upgrade your existing windows to conform with Low-e glass performance, and at a fraction of the cost of replacement windows.

Clear Low-e window film is a retrofit product, that can be applied to existing windows, without the need for replacement. This is not just an easier option; it’s also around 80 percent cheaper, and by reflecting 25% of interior heat back into the room, there’s no compromise on performance either. Additionally with window film, the promise of energy saving extends beyond the winter months, allowing for reduced energy consumption when the sun comes out during the summer.

The energy-saving focus is rightly pointed at insulation during these colder months. But it needs to be acknowledged that during the summer months, internal temperatures dramatically increase due to solar heat gain, and end up being remedied by the use of another costly and energy hungry solution, air conditioning. Left unchecked, this represents a huge energy burden on businesses that totally negates the energy savings that insulation may provide.

Unlike most low-e glazing, low-e window film is not only able to keep the office or home warmer in the winter, but cooler in the summer. By blocking a significant amount of solar heat from entering the building when temperatures are high, interiors remain at a stable temperature and the need for air conditioning is reduced. Coupled with its insulation benefits, the result is year round comfort, and a greatly reduced energy burden no matter what the weather is like outside. This can only be positive, saving money and increasing comfort.
