Solar Spectrum

Ultraviolet - approx. 5% and causes sun fading or bleaching damage and a deterioration of the wood protection.

Visible - approx. 45% and creates the wave lengths that allow us to perceive colours.

Infrared (IR) - approx. 50% of the sun’s energy that hits earth are infrared rays, and these are what we as people experience as heat. The heat is harmful for the wood protection and the wood, because the heat makes the wood expand every time the sun shines on it.
