Does Insulation Reduce Noise?

Many people are aware of the energy savings insulation offers, but what’s less known is its soundproofing benefits. Yes, insulation is a great way to lower your energy bills and live more comfortably year round, but it’s also a great way to reduce outside noises and noises between different rooms and levels inside your house.

The answer to “Does insulation reduce noise?” is yes (it’s one of the biggest benefits insulation installation offers!), but we’ll get more into how insulation reduces noise in this post.

How Does Insulation Reduce Noise?

Limiting the transmission of sound from one area to another requires a material that encloses the source of the noise, forming a barrier between the source and the adjacent areas. This is exactly how insulation works!

Not every type of insulation reduces noise, of course. Reflective insulation like radiant barrier works by reflecting the sun’s heat away from your home to keep it cooler and more comfortable, but it doesn’t provide any soundproofing.

So what is the best type of soundproofing insulation? The best types of soundproofing insulation are blown-in fiberglass and cellulose. They are superior at reducing not only outside noises but also noises from room to room and between different levels of your home or building. For the best results, the insulation should be installed in the walls, floors and ceilings.

Insulation and Soundproofing: Airborne & Impact Noises

There are two types of noises: airborne and impact. Airborne noises are the noises from outside (traffic, voices) and also include noises from the TV, music and other things inside the house. Impact noises include footsteps and vibrations from large appliances such as your washer and dryer. Insulation reduces both airborne and impact noises. You’d be amazed at how much louder noises from your neighbor’s apartment or outside on the street seem if your walls (both interior and exterior) aren’t properly insulated with cellulose or fiberglass!

If outside noises seem unusually loud and you’re wondering how to reduce them, insulation is a great solution. This is especially beneficial for those living in cities or other high-traffic areas and people in apartment complexes, where noises tend to be louder.
