Do Roller Shutters Reduce Noise?

How roller shutters reduce noise

Sound travels through the glass of a window. A closed shutter adds a solid layer in front of it, with a gap of air in between, which dampens sound before it reaches the glass. It also stops rain and hail hitting the window directly — something many people notice most.

What affects how much quieter it gets

• Whether the shutter is fully closed
• How well the shutter fits the opening and guide rails
• The type of shutter and slat
• The type of noise — low rumbles are harder to block than voices
• Other gaps around the window, vents and doors

Roller shutters vs double glazing

Double glazing improves the window itself; roller shutters add a barrier outside it. Double glazing works whether the shutters are open or closed. Shutters also add light control, privacy and security. Where noise is a serious problem, using both gives the best result.

Where people notice it most

Bedrooms facing busy roads, homes near train lines or flight paths, and rooms where rain on the glass is loud. For many households the combination of darkness and quiet is what makes the biggest difference to sleep.
