Energy Efficient Window Film & Automatic Blinds

The need to conserve energy is becoming ever greater, and regulations and environmental standards on energy consumption and emissions are becoming increasingly stringent. So, businesses of every size are coming under more and more pressure to reduce their energy levels and their carbon footprint. Air conditioning can account for 30-50% of a company’s annual energy bills, and energy costs are rising.

Our innovative window treatments can help you increase your energy efficiency, improve the working environment and lower your heating and air conditioning costs. We also offer a consultancy service, with advanced before and after modelling of the thermal performance of our products, so you can see for yourself the effects our market-leading window films and blinds will have on energy savings. 

Energy Analysis

We offer two energy analysis surveys, to give you the opportunity to see exactly how your business will benefit from our innovative window treatments. Using complex modelling software, we can help you identify quantifiable savings in both energy costs and carbon footprint reduction. 


We use CAPSOL modelling software to accurately forecast the impact of retro-fitting solar control window film, in terms of energy and cost saving. The CAPSOL building simulation software tool allows you to calculate the return on your investment of installing window film, over a period of time. CAPSOL is used by organisations such as The International Energy Agency, the U.S. Department of Energy, The International Organisation of Standards and The European Union.

For a full CAPSOL report, an energy specialist will produce a complex software model of your building, considering all factors, to give an accurate forecast on the return of your window film investment. 


CAPSHOT leverages the CAPSOL modelling engine, concentrating on a building’s glazing and cooling systems, rather than walls, floors and roofs, which make less of an impact. This still gives a valuable insight into potential energy savings and the return on your investment of installing window film, for a lesser cost than a full CAPSOL analysis.

Window film

Energy prices are increasing, making window film a highly effective solution for controlling heat and light. Installing solar window film to new or existing glazing can deliver a valuable 5-10% energy saving. As well as reducing your air conditioning usage in the summer, solar window film saves energy through the winter by insulating your glazing and reflecting heat back into your building.

Reducing air conditioning and heating costs with solar window film is one of the most environmentally friendly ways to improve your company’s performance. In addition to the long-term benefits, solar window film’s carbon footprint is significantly lower than glass, and eliminates the waste and disposal costs associated with replacing your glazing. 


Our intelligent automatic blinds provide a dynamic solution to managing the levels of heat and light across your building. The unique cellular structure of our insulation blinds traps air, rather than letting it escape through the glazing, reducing up to 46% of heat loss. This extra layer of insulation can reduce your heating bills by up to 25%.

With flexibility to programme your blinds to be down when you need them to be and to maximise natural light when glare isn’t a problem, our automated blinds reduce the reliance on artificial lighting and heating, bringing your energy consumption – and your costs – down.
