Unwanted noise can disrupt activities, relaxation and sleep. Fortunately, quality shutters significantly muffle sound when closed. Here are the top ways shutters soundproof rooms.

Solid Materials Prevent Noise Entering

Shutters made of dense materials like wood, composite, aluminum and PVC physically block noise vibrations from permeating in. Their solid mass deafens sound compared to lighter window treatments.

The thicker the shutter materials, the higher the noise reduction rating. Multiple shutter layers amplify sound dampening.

Tight-Sealing Frames Deter Noise Infiltration

Snugly fitted shutter panels with tight seams leave no gaps for noise intrusion. Insulating stripping around shutter edges also blocks sound leakage.

Soundproof mounting hardware that integrates shutters into frames helps prevent vibration transmission.

Strategic Placement in Noisy Zones

Install shutters on exterior walls facing noise sources like streets, airports, schools and parks. Keep them closed when noise is disruptive.

For homes on busy roads, use shutters throughout rooms that face the street.

Layer Interior Shutters with Existing Windows

Adding interior shutter panels behind existing windows doubles sound buffers. The air gap between the layers helps dissipate noise vibrations.

This upgrade is simpler than replacing windows and achieves better soundproofing with less work.

Noise-Reducing Window Films Under Shutters

Apply sound-dampening window films to glass before installing shutters over them. This optimized noise control by using multiple barriers.

Special acoustic films work better than basic tints for effectively absorbing sound and minimizing vibration transmission.

Supplement With Weatherstripping and Seals

Seal shutters thoroughly with weatherstripping around the full frame perimeter to prevent noise infiltration through gaps. Acoustic caulking also helps soundproof seams.

Sealing improves general window insulation as an added benefit beyond just sound reduction.

Choose Laminated or Acoustic Glass Shutters

For maximum effect, select shutters using laminated or acoustic glass instead of regular glass. Multi-layered and noise-reducing glazing blocks more sound within the shutters.

This upgrade is especially effective for windows facing intensely noisy areas such as freeways.

Combine Shutters With Interior Curtains or Drapes

Layering shutters with sound-absorbing curtains or drapes creates a noise barrier sandwich effect. The cushy interior materials further dampen sound vibrations.

Use blackout curtains over shutters in bedrooms to also block early morning light.

Add Interior Foam Insulation Behind Closed Shutters

Affix rigid foam insulation behind shutters for enhanced sound dampening. The foam disrupts noise vibrations while the shutters block sound.

Use high density polyurethane or extruded polystyrene foam for best results.

Utilize Sound Dampening Shutter Backing Boards

Installing acoustical damping boards such as mass loaded vinyl behind shutters absorbs noise. Sound waves entering the vinyl lining convert to minimal vibrations.

DIY kits are available or hire sound contractors to professionally install optimally performing materials.

Conclusion

Quality shutters applying sound blocking materials and strategic installation techniques effectively minimize noise problems. Consult acoustics experts to target specific issues for the highest noise reduction.
