OPALFILM® ECOLUX in a practice test

A comparative test has proven that the installation of OPALFILM® ECOLUX sun-protection films offers a cost-efficient and, above all, effective way of reducing the cooling energy requirements of air-conditioning systems. A number of hotel room windows were fitted with several different OPALFILM® ECOLUX variants, while the windows of other rooms – of similar layout – remained without the coating. The results were unequivocal:

Long-term comparative measurements have verified that the rooms equipped with OPALFILM® ECOLUX sun-protection films did not heat up as much as rooms with no such films; as a result the air conditioners in these rooms were needed less frequently. The result was a significant decrease in the energy consumed by air-conditioning systems.

OPALFILM® ECOLUX – The energy-saving film that improves the room climate

OPALFILM® ECOLUX sun-protection films for windows and glass fronts are an ideal solution for anyone interested in enhancing their energy efficiency and climate protection and who is looking for a simple and comparatively inexpensive, retrofittable sun-protection solution for providing the benefits of an improved room climate.

The special energy-saving film is designed for exterior use and is particularly suitable for rooms with large windows. It is a genuine alternative to the more costly approach of replacing the actual windowpanes. In summer, it provides effective protection against the heat, while in winter, the film system reduces heat loss and in turn enhances the room's living and working comfort.

An additional advantage is that OPALFILM® ECOLUX films do not change the appearance of the building's architecture.

The efficiency of the energy-saving film has been verified in several tests.
