Banners are typically designed for short-term messages, such as “Sale On Now” or “Merry Christmas.” Outdoor banners endure moderate to extreme environmental conditions, which, over time, cause them to fade and deteriorate. While mesh banners can withstand the elements, higher winds and increased sun exposure accelerate their deterioration. North-facing banners last up to four times longer than south-facing ones. Banners restricted from movement, despite becoming stiff, can last seven years or more.
