GlaxoSmithKline Marly-le-Roi (FR)
GlaxoSmithKline (GSK) is one of the largest pharmaceutical companies with offices around the world. At the site in Marly-Le-Roi France, they faced large heat losses through the windows in winter. They decided to install Umisol® IR films which were applied to ordinary double glazing with a K-value of 2.9. Tests have shown that there is a significant improvement in thermal insulation, resulting in an increase of the average interior temperature of 3.5 ° C in winter.
