There are two main reasons why many of our clients inquire about covers (protectors) for their LED signs: vandalism and weather. Covers are made out of a material called Plexiglas. This material is not always weatherproof because moisture build up may be common, hence blocking the visibility of your sign. Another issue that occurs with Plexiglas covers is that of the glare from the sun, again inhibiting visibility. However, if vandalism if your concern, note that 99% or more LED signs are never vandalized during their lifetime. In any case, if vandalism does occur, your insurance company should cover the occurrence and provide you with plenty resources for repair or replacement of the sign. LED signs manufactured by all manufacturers take into consideration natural hazards and therefore incorporate weather guards which protect the sign from sun, hail and other natural forces. In addition to incorporating these protection elements such as silicone and weather grills for our LEDS signs, we also meet the best industry standards for visibility, brightness and overall quality of end product.
