Banner substrates differ in weight, opacity, and wind resistance. Choosing the wrong one for the install (e.g. solid vinyl in high wind, or mesh where you need full opacity) leads to failure or poor appearance.
Scrim (solid vinyl)
Scrim is a solid vinyl banner material. It is opaque and good for one-sided signage. In high wind it can billow and stress the grommets or frame. Use where wind load is moderate and you need full opacity.
Mesh
Mesh has small holes that allow wind to pass through. It reduces billowing and is used for fence wraps and outdoor displays where wind is a concern. It is not fully opaque; light can show through from behind.
Fabric
Fabric banners (e.g. front-lit or back-lit) are used for indoor or controlled outdoor use. They can be folded for transport. They are not for heavy weather or long-term outdoor exposure unless specified.
Selection guide
• One-sided, moderate wind: scrim.
• High wind, fence or large frame: mesh.
• Indoor or portable: fabric or scrim depending on use.
Common mistake
Using solid scrim in a very windy location. The banner can tear or pull hardware out. Specify wind conditions and install type so the printer can recommend scrim vs mesh.
