When rolling shutters are in the closed position, they are virtually indestructible. When the store is open, the rolling shutters disappear into a color-matched box housing. Solid aluminum shutters reduce break-ins and virtually eliminate the threat of smash and grabs. Solid aluminum shutters also provide extra insulation, helping to reduce energy costs.
