Perforated Roller Shutter
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.
