At 4OVER4 we use 60/40 vinyl which has an open area of roughly 40%. That allows for the perfect ratio of vinyl and holes to maximize resolution on our exclusive 6 mil white flexible vinyl with removable acrylic adhesive backing. In addition, for extra durability, we also provide UV protection and weather-resistant features for outdoor applications. To order Perforated Window Vinyl click here. We can also do a custom open area of 70/30, but you would need to contact the Support Team for a custom quote, Contact Support Team at Support@4over4.com or use the Custom Quote page to submit your request https://www.4over4.com/custom-project
