From the French fenêtre, meaning “window,” comes a security door with an appropriately more sophisticated design than the rest. Alumatec Pacific Product’s fenestrated rolling shutter door, the FSR, is similar to the S-2 model: we’ve also designed this door for larger openings that require a solid shutter. However, the FSR includes fenestrations, or windows, which allow for more visibility and ventilation while still ensuring safety and security. When you’re looking for a security rolling shutter that’s a little more chic than the others, consider this fenestrated rolling shutter door.
