Heat-free as standard: The patented skai® cool colors technology

Dark surfaces heat up more than light surfaces in the sun. A fact that plays a role for vinyl window profiles, especially in southern countries. The more heat is transferred to the profile system, the more unstable it becomes. And the darker the colour, the greater is the risk of damage to the window in hot regions. But because the market also demands dark colors and designs, we developed the skai® cool colors technology.

How does skai® cool colors work?

This innovation ensures that the window heats up noticeably less. Special pigments reduce the thermal effect of the near infrared radiation of the sun. Thanks to the patented skai® cool colors technology, the predominant share of this radiation does not penetrate into the profile, but is reflected by the surface. The penetration of heat into the profile is clearly lower, the surface remains “cool” and the form of the window remains stable.

Thus, skai® cool colors extends the life of the window. Now, we equip about 80 colors and designs with cool colors technology. The original, which premiered in 2006, is still the standard and has spawned numerous copycats.

A further development is skai® cool colors PLUS, which is additionally equipped with a white base layer and thus is even more effective. In this way, a dark base is completely neutralized. Therefore, it is especially suited for extreme climate conditions.
