Solve heat and glare issues, reduce your carbon footprint and save on bills.
Energy Saving Window Film, Reduce Heat Loss and lower your carbon footprint. Save on bills in London Kent
Keep your building more comfortable for less!
Whether you goal is to reduce operating costs, decrease carbon emissions or create a more comfortable and productive environment, we can offer a fast, non invasive and cost efficient solution for customers in London, Kent and the South East.
Your buildings windows offer one of the best opportunities for energy savings. Solar energy enters through the windows and causes heat to build up inside the building, leading to an uncomfortable work space and an increased need for air conditioning.
With proven heat rejection our solar control window films can dramatically reduce any heat and or glares issues as well as reduce your air conditioning consumption by up to 30% and in turn reducing your bills.
Solar control window film is less costly than installing new windows and more efficient than low-E coatings at rejecting solar heat. All of our window films can be installed internally or externally and come with a 5-20year warranty depending on the window film.

Save money and energy
Our solar window films can cut down your cooling costs and energy consumption with little to no disruption to your workforce. By installing solar window film you can reduce your energy use by up to 30% and reject up to 79% of solar energy. One of the world’s top energy research centres found that window film tops the return on investment list when compared with window replacements, blinds, awnings and reflective roofs.
Decrease your energy use and reduce your carbon footprint
When you decrease you energy use, you are reducing your greenhouse gas emissions – and your buildings carbon footprint. Our solar window films are carbon negative, producing a net reduction in greenhouse gas emissions over their lifetime, they are in many cases carbon neutral within one month of instal. In short this means that the film saves more energy when they are installed than it takes to produce them. The carbon cost of one square meter of solar window film is less than 10 kilograms. By comparison, a low-e wood frame window has a carbon cost of approximately 444 kilograms per square meter. Over its useful life solar window film saves 100 times more greenhouse gas emissions from entering the atmosphere than is used or created during its manufacture.
Solar window film eliminates harmful solar rays
Solar window film filters visible light and blocks more that 99% of harmful ultraviolet ( UV ) light associated with premature ageing and skin cancer. With an SPF of 285 +, window film can also protect furnishings, carpets, art and more from fading and damage due to UV exposure.
