All films used to laminate windows use "Cool Colors" technology. Thanks to the use of innovative, patented pigments, a significant lowering of surface heating from sunlight has been achieved. This means even the most "heat-absorbent" surface films like mahogany or anthracite wont heat up to the frames critical temperature of 78°C (in the case of standard films that temperature can be as high as 96°C). The result is complete elimination of stresses that can cause permanent damage to window frames.
