Modern-day architecture holds glass in very high esteem. You get to live with the greenhouse effect the whole year through: the glass uses its insulating function to keep heat from the sun's radiation inside. This means interior walls, floors, ceilings and furniture are all warming up.
This heat remains in the room and causes overheating.
Tinted glazing keeps just 30% of the sun's heat outside. Roller blinds, venetian blinds and sun-resistant awnings are not really effective. They also generate local heating which results in convection radiation.
And what about the air-conditioning? In warm periods every climate control installation runs on full power with a heavy energy factor as a consequence. Furthermore, the lack of thermal comfort results in worse work performance and makes glare appear on screens quickly, which can be very troublesome.
 The foils block up to 93% of infrared heat rays out and lower the indoor temperature up to 10°C.
The foil reduces the costs of your climate control: in the summer it keeps the sun out and in the winter it keeps the warmth in.
Using the Luxasolar® window films the cooling loads demanded by air conditioned buildings can be substantially decreased. This means your climate control will use significantly less energy and that's good news for both the environment and your budget.
Luxasolar® window films work as a filter. Warmth radiation up to 21°C still passes through, but above that temperature the sun heat is filtered. The higher the outside temperature, the higher the drop of temperature caused by Luxasolar® is. For an optimal result, it is recommended that you have all windowpanes through which the sun can shine in, treated with a glass foil.
 During winter time the foil reflects the interior heat, that usually goes lostthrough large glass panes, back into the room. The thermal insulation is considerably improved, as a result of which savings of up to 30%can be achieved on fuel costs, depending on the type of glazing. After the installation of Luxasolar® window films, the U-value of single pane glazing is improved to the U-value of double pane glazing, the U-value of double pane glazing is improved to the U-value of HR+ glazing, and HR+ glazing to the U-value of HR++ glazing.

Normal single pane glazing has a U-value of 5,8 W/m²K. After installation of Luxasolar this value is improved to 2,5 W/m²K = improvement of 57%.
Normal double pane glazing has a U-value of 2,9 W/m²K. After installation of Luxasolar this value is improved to 1,6 W/m²K = improvement of 45%.
Normal HR+ glazing has a U-value of 1,1 W/m²K. After installation of Luxasolar this value is improved to 0,97 W/m²K = improvement of 12%.
So, a maximum comfort is provided during summer AND winter.
The UV rays are blocked at 99%, and therefore the fading of your interior is stopped.
Also, once installed, Luxasolar® provides you with an extra security. Glass is a fragile building material and is also very attractive for burglars.
Luxasolar® window films strengthen your glass surfaces and ensure that shards of glass do not injure you if the glass is broken.
The glass foil is applied to the inside of the glazing without any cutting or breaking work.
The windows can be maintained normally thereafter. Luxasolar® comes with a 10 year guarantee.

"The European Commission and the World Trade Center save up to 30% in energy consumption using sun-resistant, energy-saving glass foil from Luxasolar®"
The European Commission has recently reached an agreement on measures to counter global warming: by 2020 Europe has to use 20% less energy as well as reduce its CO2 emissions by 20%! In the building of the European Commission DG Environment in Brussels, where the climate change and Kyoto departments are, 2.300 m² of Luxasolar® have already been installed. This sun-resistant and energy-saving metallic foil helps achieve energy savings of up to 30% as well as a major reduction in CO2 emissions. By installing Luxasolar®, the European Commission now achieves assumed standards and keeps the energy bill of its buildings under control.
