Finding the right balance of temperature throughout a building not only has a great effect on reducing energy costs, it also has a huge impact on the productivity of employees and the comfort of customers. Lots of windows can create intense heat in the summer and make workplaces too cold in the winter. And the environment people work in contributes to everything from performance to absenteeism and staff retention.

Building management systems simply can’t make an area comfortable for everyone, but our market-leading window films and intelligent blinds can. By controlling room climate, our window solutions allow you to effortlessly create a comfortable and consistent environment, throughout your building. And with our advanced before and after modelling of the thermal performance of our products, you can see for yourself just how you and your business could benefit.

Solar Heat Gain

The sun’s radiant heat can have a large effect on the comfort and productivity of your employees, at any time of year. In the summer months, the sunlight penetrating your glazing can create intense heat, which can impact on happiness, wellbeing and performance.

Our innovative solar window film prevents the sun’s radiation from entering through your glazing, to create a balanced and comfortable temperature throughout your building. Without hot spots and unbearable heat, you’ll increase the wellbeing and productivity of your employees, and reduce your carbon footprint.

Window film

With unique heat management technology, our state-of-the-art solar control window film reflects up to 97% of the sun’s radiant heat before it enters the glass. When applied to your existing glazing, our window film offers exceptional protection against fluctuating temperatures and hot spots, creating a balanced and comfortable environment, all year round.

Offering high visible light transmission and optical clarity, our solar window film is virtually undetectable, and the climate control benefits can significantly reduce your air conditioning costs – a typical payback period would be around three to eight years. You can also combine solar window film with our safety window film, which protects against impacts and forced entry, for added safety and security that pays for itself. 


A window can lose up to 20 times more heat in the winter than the same area in an adjacent wall, and the temperature across your building can vary greatly. On a shaded side there can be a significant difference in climate, making it impossible to for air conditioning or heating to create a comfortable environment for everyone.

Our revolutionary window insulation products balance the temperature across a building, for an even climate, and helps to decrease your heating costs. Without the need to replace windows, our insulation solutions can upgrade your existing glazing quickly and highly effectively, at a fraction of the cost and with little disruption to your business or your employees.  

Insulation window film

Body heat is constantly being lost to surroundings, when radiant heat transfers from a hot surface to a cold one. Our innovative insulation window film reflects a massive 90% of this heat back into the room, so even sitting next to a window doesn’t feel cold. Our low-e film offers the best insulating performance of any window film available, and is virtually invisible, so won’t change the aesthetics of your windows and can be used on listed buildings.

Our window film improves the insulation value of a single pane window to almost that of a double pane window, and a double pane close to that of a triple pane. This makes for a highly cost effective way to upgrade existing glazing and reduce dependency on heating systems – alongside year-round comfort for your employees, you can benefit from up to 10% energy savings and carbon emissions reductions. With the added protection of blocking 99% of the sun’s harmful UV rays, our insulation window film will also help to prevent furnishings, flooring and artwork from fading.

Insulation blinds

While they can be effective, manual blinds are rarely properly utilised. Our intelligent insulation blinds put you effortlessly in control of the temperature around 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%.

Versatile and easy to maintain, our intelligent motorised blinds offer the added benefit of being noise absorbent and give you complete control over the settings at a touch of a button. The automation system lets your timer take care of everything and will even monitor light levels, as well as temperature. With our motorised insulation blinds you can effectively preserve your heat, keeping your employees happy and productive, and your energy bills down.
