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 free 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 Freephone 0800 077 8403.

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.

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, which can be reduced by simply applying energy control window film to your windows, which will stop as much as 80% of that solar heat gain and reduce your CO2 emissions by up to 30%, hereby not only reducing your energy costs, but also your carbon footprint.

Hence, by reducing your air conditioning needs and costs, this window film will be beneficial to your business, but also make you an environmentally friendly business.

Lighting contributing 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 rejecting unwanted solar heat gain.

Guardian is proud to be a member and supporter of The UK Sustainable Development Association.

Formed and established consequently to the rising need to optimise and preserve the Earth’s resources, the Association and its members aim to encourage access to and use of sustainable and environmentally responsible technologies and services.

All members detain expertise in the use of technologies and techniques required to reduce the negative impact of existing urban environments and new building projects. The Association is therefore a resource available to assist both the public and private sectors in formulating carbon footprint policies at national, regional and local levels, which we strive to participate, encourage and support through providing high quality and environmentally responsible window films products and services, not only by being conscious and careful of how we operate, but also by offering innovative window film technology, in line with growing concerns about gas emissions, and natural resources’ exhaustion, such as our energy control window film.
