Internal Perforated window film products transform glass with one-way vision graphics which cannot be seen from the other side. The graphics are used for advertising, branding or to achieve decorative effects. These films  provide privacy and solar control benefits to people inside buildings and vehicles without blocking their view outside. This product is for applying internally to the window.

How does perforated window film work?

The internal perforated window film effect is most commonly achieved by applying a self adhesive window film to the inside of the glass. The film contains areas of printed graphic (a print pattern) as well as unprinted see-through areas covering up tom 80% of the film. When looking at the side with graphics, the eye is drawn to the printed colours as they reflect more light than passes through the see-through areas (provided the lighting on the outside is brighter than the inside). The secret behind the one-way vision effect is ensuring the printed graphics are obscured or hidden from the other side of the glass. This is best achieved by having a black "backing" which covers exactly all the printed areas on the film without blocking the see-through (unprinted) areas. We achieve this on our Durst P10 250 HS+ printer by printing 3 layers. 1st layer is the image reversed on to the film, 2nd layer is pure white ink giving opacity to the printed image below and the 3rd layer is pure black ink which gives better vision from the inside looking out. When looking through the reverse side of the film, the view coming through the film is dominant because the black layer absorbs light and is less apparent to the eye.

Frequently Asked Questions

What is Internal Perforated Window Film?
Internal Perforated Window Film (often called One-Way Vision or Contra Vision) is a specialized vinyl that allows you to see out of a window while people on the outside see a full-color printed graphic. This "Internal" version is unique because it is applied to the inside of the glass, facing out—ideal for high-rise offices or shops where exterior application is impossible.
How does the "One-Way Vision" effect work?
The film is manufactured with thousands of tiny perforations (holes). We print your design onto the white surface of the film, while the side facing you is black. Because the human eye focuses on the bright, printed image on the outside and ignores the black surface on the inside, the film appears transparent from the interior but opaque from the exterior.
Why choose Internal application over External?
Internal application offers several key advantages: Easy Installation: No need for ladders, scaffolding, or cherry pickers for windows on upper floors. Weather Protection: The graphic is protected from rain, frost, and UV fading by the glass itself. Vandalism Proof: It cannot be peeled off or "tagged" with graffiti from the street. Longevity: Shielded from the elements, internal film typically lasts much longer than exterior alternatives.
