Our standard windscreen mesh banner material has a 80/20 ratio. This means that 80% of the mesh material is solid, and 20% of the mesh material is open to allow air to pass through. While the vibrancy of windscreens may be slightly less than it would be on a solid vinyl material, you will find that windscreens still appear to be vibrant and are sure to catch the eye of anyone passing by. If you need to allow more air to pass through your windscreen, please discuss this with your Account Manager as there are a couple different material options that could work for your project needs!
