A Rollac shutter can provide excellent soundproofing and noise control for a commercial building. Offices located next to busy roads, airports and factories could close external shutters and be restored to a peaceful working environment. Automation is possible via decibel detectors so shutters can automatically close when noise pollution peaks outside. Internal roller shutters can be installed to divide noisy workplaces such as factories and garages from quieter areas devoted to customer service and office space.
Too bad you can't put Rollac Shutters on your office door to keep out that guy.
