If you are looking to soundproof an indoor space, then you may be pleased to find that you have a lot of options when it comes to soundproofing materials. However, you might also be a little confused. Like, which product is right for you and your particular circumstances? One soundproofing material that is getting a lot of attention lately is Green Glue. What is Green Glue, and how can you best put it to use in your soundproofing project? Here are some things you might like to know:
How does sound work? Before you can understand how Green Glue works to eliminate sound, it is best that you understand how sound travels. Basically, sound is a series of waves. These waves travel by vibration; that is, they vibrate the materials they move through in order to make space to travel. Sound actually travels faster through solids because the molecules of solids are packed more densely together, and are therefore easier to vibrate.
What is Green Glue? Green Glue is what is called a damping compound. It dampens - or dissipates - vibrations, making it difficult for sound to pass through. It does this by turning sound energy into heat, and then quickly dispersing the heat. Currently, Green Glue is the highest performing product of its type on the market, according to lab and field tests.
How is Green Glue used in building applications? Green Glue is what is called a Constrained Layer Damping System. In simple terms, that means it must be applied between two solid surfaces in order to act as a soundproofing element. For walls and ceilings, Green Glue is generally applied between two layers of drywall material; for subflooring, the Green Glue is often applied between two layers of plywood. You don't need any special tools to apply Green Glue - only a standard caulking gun.
Why not just use factory damped drywall panels? First of all, Green Glue is actually cheaper than factory damped drywall panels. Second of all, you get much better soundproofing when you use Green Glue, for two reasons: 1) Green Glue is a higher quality product than standard factory damping products used on drywall, and 2) When you use Green Glue, you are actually using two layers of drywall, which is naturally better than using only one layer. Additionally, it is important to note that there is no product waste when you use Green Glue, as compared to using factory damped drywall. You simply apply the Green Glue only where it is needed.
As you can see, Green Glue can be a great option when it comes to soundproofing your indoor space. When you consider all of the advantages of Green Glue, it's hard to come up with any reason not to use it!
