Anything is UV stable for a certain amount of time, whether that be days, weeks or even years. The vast majority of products do not have any certifcation to prove that they have been tested. However, Vistafolia’s artificial living walls are UV stable and have undertaken vigorous testing to high irradiance levels to ensure that it is the most UV stable on the market. Therefore, this means that Vistafolia’s artificial green walls are the strongest in the market when it comes to battling against the Sun’s radiation. Other competitors will tell you that they are UV stable but aren’t actually certified and thus you cannot be sure of what you are buying. Vistafolia are the only provider of artificial living walls with both UV and Fire retardant certifications. Be sure to double check if going elsewhere.
