When you need visibility and privacy, Perforated Window Film (also called “window perf”) offers the best of both worlds. Used on storefronts, vehicle windows, and building glass, this unique vinyl has tiny holes that let you display full-color graphics on one side while maintaining visibility from the other.
What is Window Perf?
Window perf is a printable vinyl film with a grid of perforations. These holes allow light to pass through while displaying a solid image on the printed side. The unprinted adhesive side remains see-through from inside the window.
Hole Patterns & Transparency Options
Not all perforated vinyl is the same; it comes in different perforation patterns that affect visibility and print quality.
| Pattern | Print Surface / Open Area | Best For |
| 50/50 | 50% print / 50% holes | Balanced visibility and image quality |
| 65/35 | 65% print / 35% holes | Bolder graphics, slightly less see-through |
| 70/30 | 70% print / 30% holes | Vivid print, more light blocked |
Why Lamination Matters-Especially on Vehicles
While Perforated Window Film looks great on its own, laminating it is crucial, especially for vehicle installations. Here’s why:
- Prevents Water Intrusion: Without lamination, rain and car washes can force water into the holes, creating a blurry, distorted view from the inside.
- Improve Visibility: A clear overlaminate forms a smooth surface, helping water sheet off the film instead of pooling in the perforations.
- Protects the Graphic: Laminate shields the ink from UV rays, scratches, and wear, extending the life of your print.
- Safer Driving Experience: On rear or side vehicle windows, clear visibility is essential. Lamination ensures your branding doesn’t compromise safety.
For any automotive or high-exposure outdoor use, we always recommend pairing Perforated Window Film with an optically clean laminate.
Common Uses
- Vehicle Windows: Transform back or side windows into mobile billboards
- Storefront Glass: Promote sales or branding without blocking natural light
- Offer Partitions: Add privacy to meeting rooms while keeping a modern look
- Event Graphics: Wrap large glass areas with temporary promotional graphics
Why Use Window Perf?
- One-way Visibility: See out without lettings others see in.
- Advertising Space: Turns windows into high-impact real estate.
- Easy Application: Installs like standard vinyl and can be removed cleanly.
- Customizable Coverage: Choose perforation ratio based on your privacy vs. image needs.
Application Tips
- Apply to clean, dry, flat glass
- Use with an optically clean overlaminate to enhance durability and visibility.
- Rear vehicle windows are typically curved, which can make installation more difficult. Use heat carefully to ease application and avoid stretching the material.
- Avoid using on surfaces with sharp compound curves or non-glass materials.
