More energy is often used in cooling a building’s temperature using air conditioning than in heating the building. Indeed, heat in buildings most often emanates from solar energy as well as internal heat generated by people, technology and poor ventilation. Energy Control Window Film applied to the windows enhances the performance of the windows by reducing glare  and solar heat gain, as over 40% of the load placed on air conditioning is known to come from direct solar gain through the windows.


The reduction in the load on air conditioning units achieved by the application of Energy Control Window Film to the windows in a building can save up to 30% of the air conditioning costs. The payback period for the cost of the installation can be as little as 2 years and the film will typically continue to enable savings for up to 20 years in the case of an internal application and 10 years in the case of an external application.


Energy Control Window Film helps maintain a comfortable working environment leading to increased productivity whilst also meeting relevant Workplace Compliance Regulations.


Guardian offers a personalised energy savings analysis for your property. We will provide a comprehensive report detailing the savings our window film could allow you to make. For more details and to get a free quote, please call us now on 0121 693 4747

The Building Energy Analysis carried out for the Royal Caribbean House near Weybridge identified that potential energy costs savings of more than £2,000 per annum – with a payback period of just 3 years – could be made with the application of Guardian’s Energy control window film.

The works were duly commissioned and with an estimated lifespan of 15 – 20 years the costs of installing the window film will be reimbursed over 5 times. Similarly to UV Window Film and Solar WIndow Film, the Energy Control Window Film reduces glare by more than 80% and rejects 99% of damaging UV rays.

carbon footprint


According to a research carried out by the Building Research Establishment (BRE), 40% of the load placed on air conditioning in offices comes from direct solar energy gain through the windows. Installing energy control window film to your windows could stop as much as 80% of that solar heat gain and reduce your CO2 emissions by up to 30%. This will reduce not only your energy costs  but also your carbon footprint and contribute to your being an environmentally friendly business.

As lighting contributes to around 25% of overall energy consumption in commercial environments, we also use the most advanced technologies to ensure our window films still allow high levels of natural light transmission whilst filtering and rejecting unwanted solar heat gain.
