Do cork wall tiles change color in UV light?Updated a year ago

Cork, as a natural product, may change in color when exposed to natural light over a period of time. Cork will tend to fade while most woods will darken/mellow. You can either accept the fading as part of the natural progression of cork, or you can apply UV window treatments and/or UV protective finish to the cork. UV finishes have not been tested by Jelinek Cork. While we've had customers report that they have successfully applied a finish, we aren't aware of the specific brands/types they have used.
