Our rolling shutters are approved by TDI, IBC/IRC, FBC, and Miami-Dade County for hurricane protection. Architectural Drawings and Engineering are available on the engineering page. Naturally efficient, rolling shutters block 99% of light before it reaches the window to provide you with energy savings that are unheard of. Rolling shutters act as a barrier between your home interior and the outside world. Not only do shutters provide light control, but also a moderate sound barrier.
