Wind slits

[Aardvark Printing]

I'm putting up a 8' x 97' mesh banner that will wrap completely around a side walk dining area under a canopy.
This will be up for a few months while the business is closed during a remodel. Do yo thing wind slits are necessary?
It will have grommets every 2' attached to the canopy frame top and bottom. Any comments would be appreciated.

No wind slits. Not if its a mesh banner

Around here they would board that up and then put a banner or graphics over that.

I agree with both comments above. Post some photos when you’re done! (and don’t forget to put them on your Facebook page and google my business profile)

There was a study years ago on wind slits in banners in one of the sign mags. It concluded that wind slits do not help at all in taking pressure off of material if it had the wind slits or not having them. It weakens the material by cutting into it.
So no wind slits!

You are right about the wind load. I installed sat dishes back in the 80 and a solid dish had the same wind load as a screen one due to the fact of the turbulance the screen caused

The wind slits lessen the wind load exerted on the structure it's attached to. No slits needed on a mesh banner. Examine the canopy frame, be sure it will support the extra stress exerted by the banner.

Exactly... Poles will usually fail before a banner does. With mesh, as long as what they're mounted to is structurally sound, you shouldn't have any issues unless conditions are so bad that people shouldn't be outside anyway. We have an annual music festival on an island in the river, and they put a large banner up over a pedestrian bridge for it, the poles had bent a few times, snapped off once over the years during storms, even with wind slits. Amazingly the banners themselves were still in tact. No problems since they went to mesh.

It's stout and well anchored.

Winters are pretty mild here. If were up in the summer I might worry.

Mild winters??? Wish we had those here in Wisconsin...

It's Tucson. I don't recommend it in the summer. 68 days this year over 100° F.

NO WIND SLITS!!!!!!!!! no matter what material.

if you are already doing mesh, why add slits?
typically this is for safety and so adding slits only allows people access to the interior easier
