Perforated Electric Rolling Shutters
Perforated rolling shutters are complete with perforations or punchings for through-vision, making them a popular choice for applications such as shopfronts. Punched slats are available in brick-bond or in-line styles and offer a good level of through-vision. Perforated slats have small holes offering around 25% through vision and are particularly effective for retail units as they become almost transparent with good back lighting”
The perforated type of shutter offers the best compromise between visibility and security. With thousands of small holes a brightly lit window display is still visible but the holes are too small to allow object through. Perforated security shutters provide a transparent effect when background lighting is illuminated. This particular design of shutter offers a high degree of security with inner integral strength. Perforated shutters are commonly used when ventilation is a requirement.
