Do outdoor banners need wind slits? Sublimated versus DSG displays. And, is it normal for a banner to have a glare look?
Question: Do outdoor graphics require wind slits?
This is a favorite topic of mine as there are so many misconceptions about wind slits or wind pockets being cut into banners.
Reduction of Wind Load
Wind pockets allow about 4-5% wind load reduction on vinyl banners, which, in our opinion, is negligible and makes the banners weaker and uglier. Quite frankly, I think wind slits in outdoor vinyl banners are just ugly.
