Have you ever had to deal with unpleasant noise from your neighbors in your apartment? Or maybe you haven't but you're trying to prevent anything of such from having to disturb you? Well, you're not alone.
A lot of people find it uncomfortable living in a noise polluted environment and would do anything to prevent a situation of such.
Well today, we'll be talking about a noise-proofing compound that could help in preventing the noise or reducing it drastically.
You may or may not have heard about Green Glue but either way, I'm going to be informing you about it in this article.
Green Glue is a noise damping product that is used in new construction or renovation projects in the home, the office and even hospitals. It is a product that reduces the structural vibrations using Constrained Mass Layer Damping.
Green Glue is not hazardous and it is an environmentally-responsible and cost-effective soundproofing solution.
Understanding the science behind Green Glue needs a bit of knowledge about sound wave energy and how noise travels. Once you understand how noise travels and sound energy, you would know the principle behind the amazing Green Glue Product.
Noise is known for travelling through the air like a wave or in the form of vibrations. When these waves in the form of vibrations come in contact with a ceiling, floor or wall, the vibrations will go through the structure and exit from the other side as sound again and if this sound is unpleasant, it can be disturbing. This means that unless the structures in your home are damped, you can be rest assured that you're going to be hearing when your neighbor's door opens, when the kitchen cabinets are opened, the loud TV and the noisy blender.
Nobody wants something like that! So that's why we have Green Glue.
Like a superhero coming to the rescue, Green Glue Noise-proofing Compound possesses a polymeric formula that converts the mechanical energy from sound waves being passed through structures into small amounts of heat. When Green Glue is installed between two rigid layers of material (like drywall), it forms a damping system. In other words, when the sound waves in form of vibrations penetrate through the structure, the mechanical energy goes out in the form of heat.
Results? Less or no noise. Using just a layer of Green Glue Noise-proofing Compound sandwiched between two sheets of drywall or any other rigid surface (OSB, plywood) used can eliminate a good percent of noise including those frequencies you might think it would be hard to notice! Isn't this what everyone wants?
Where Are Green Glue Products Used?
There are majorly three Green Glue Products out there and they all have areas of best compatibility. Let's look at them briefly and the parts of the home where they are best fit.
Green Glue Noise-Proofing (Damping) Compound
Green Glue Noise-proofing Compound is used between two layers of building materials typically drywall, Oriented Strand Board (OSB), cement board, or plywood. So long as two of the layers are flat, rigid (If Green Glue is being applied between a layer of drywall and soundboard, it is not a good application, and this is because soundboards are lighter than drywall and it is not good to use in ceiling, floor or wall assembly) and are easy to stick to and at least one allows moisture to pass through then the Noise-proofing Compound will perform well.
The compound comes in bucket and tube sizes and they are liquid in nature.
It is not advisable to apply the Green Glue Noise-proofing Compound on exterior parts of your home as it is effective only at room temperature range (64-85°F / 18-28°C approximately). Exteriors are often subjected to temperature fluctuations which could be below and above this range.
Note: The Noise-proofing Compound will return to regular performance once it has warmed/cooled to the 64-85°F (18-28°C) range after being subjected to temperature fluctuations outside the acceptable range.
Green Glue Noise-Proofing Sealant
This product of Green Glue Noise-proofing Sealant which is a polymer makes cracks and gaps invisible after the whole installation job is done. It can also be used around wall sockets, outlets and any other material attached to the wall.
The sealant prevents noise leaks from escaping. It should be applied to the top and bottom of the wall where the wall meets the ceiling and floor respectively and where two walls meet. The sealant also comes with its own applicator gun for its areas of application.
Green Glue Noise-Proofing Joist Tape
This is used mostly for floor soundproofing between floor joists and subflooring. It is made out of foam with an adhesive as placement and works as a seal to dampen the noise from footsteps and floor squeaks. If you have had to deal with hearing every footstep taken above you, you'd surely want to prevent those below you from hearing yours.
Other Necessary Information About Green Glue
The materials used in Green Glue depend on frequency and amplitude. Green Glue takes about 7-10 days to dry and to start seeing a little bit of its effects; but it's full effect shows after 30-60 days depending on the number of drywall layers or other rigid surfaces used to sandwich the Green Glue. The higher the number of layers, the more the sound/noise will be damped. After 30-60 days, the noise would have drastically reduced or dissipated.
The Green Glue layer is about 0.5mm thick and can be used in floors, walls and ceilings. Green Glue can be cleaned up using Isopropyl Alcohol. The Green Glue panels should be assembled back together within fifteen minutes of application. Since the Green Glue is in liquid form, it should be applied when it is wet and so therefore, the boards must be screwed together while it is still in this state. This yields maximum results after a number of days.
How to Apply and Install Green Glue
Green Glue soundproofing solution does not need rocket science knowledge to install it. It is advisable to have to some DIY ability though but keep in mind that it might not be easy handling large sheets of drywall or boards of whatever rigid surface you would be using. But honestly, that's as hard as it could get.
Below is a step-by-step guide on how to install it for best results.
Tips and What Not to Miss out When Using Green Glue
So far, we have established some facts. Noise is disturbing so we don't want that and we have been able to identify a soundproofing compound (Green Glue) that provides solution to noise pollution. But there are some things that should be pointed out.
Green Glue is not a glue (despite the name) or an adhesive. It provides a damper solution between structures using what is known as Constrained Layer Mass Damping. This is what reduces the noise coming through the structures in an enclosed space. Yes, Green Glue only works in enclosed interiors and not exteriors because of the temperature fluctuations on the exteriors as a result of the weather and some other external factors.
Green Glue may not eliminate the noise entirely but it certainly reduces or dissipates it. So it depends on the layers of drywall or any other rigid surface used.
It is tricky and messy to work with if you're not careful. If it gets on your hands while installing, rinse off with water immediately. Once it's done with immediate effect, it comes off nicely. Otherwise, you'd have a situation. Also, do not let it get on your clothes, water or not, it won't come off. So do not wear your fancy clothes or expensive Prada, Armani or Gucci while at work with it unless the cloth is not of value to you.
Pros and Cons of Green Glue
As good as the Green Glue product comes, it has its pros and cons and takes patience to use.
Pros of Green Glue Product
Cons of Green Glue Product
Green Glue Product has been tested and trusted to provide solution to unwanted sounds that would be disturbing. The method of installation has also proven to be easy and reliable. Also when you think about it, despite that it might be on the pricy side for those on a tight budget, it is totally worth it once the results come through. You wouldn't have to put up with annoying noises from your neighbor with kids, or with the college kids who always play rap music at the highest volumes, or even the footsteps coming from occupants of the apartment above yours and they always don't get to hear what you're doing in your own apartment. So with Green Glue, it's a win-win for everybody.
So now you have been informed with soundproofing using Green Glue. When you're moving into a new apartment or renovating, you could soundproof your house and never have to knock on your neighbor's telling them to 'turn it down'.
