Despite its name, Green glue is not an adhesive; instead, it is a noise-proofing compound used for soundproofing projects.

Green Glue is sold in either 5-gallon buckets or cases of 12 tubes and helps block sound transmission in new and renovation construction projects. Its versatility and ease of use make green glue one of the most common and popular soundproofing materials for the floor, wall, and ceiling on the market today.

But despite it being one of the most common sound-blocking materials, not everyone will have access to the product. If you’re on a budget, especially if you are doing a “big soundproofing project,” you may find it a bit costlier. On the other hand, green glue may not be available in your country. Whatever the case, there are green glue alternatives that I highly recommend.

During my trip to New Zealand, I tried sourcing for this product in vain. I aimed to seal cracks in my old grandma’s house. Luckily I was able to find these great green glue alternative.

What is Green Glue?

Green Glue is a water-based, non-toxic sealant for soundproofing ceilings, floor, and wall assemblies. Sound travels through the air and is bound to collide with solid objects such as ceilings and walls. Upon collision, the sound waves transmit energy into the object they collide with, then convert to vibrations that travel to the other side of the structure.

When such structures are treated with Green Glue, the sound waves that hit the structure convert vibrations to heat. The heat is then dissipated through the structure.

Green glue’s effectiveness comes from its flexibility and ability to dampen structure-borne/impact sounds. It can be a potent tool for blocking noise transmission in apartments, condos, and multi-residential units when used alongside other soundproofing materials such as mass loaded vinyl, drywall, resilient channels, and sound clips.

You may notice some sound attenuation shortly after application, but you won’t enjoy the full benefits for around 30 days after applying Green Glue.

This is because the acoustic sealant includes water, and it needs around one month for the water to evaporate completely. As the product is temperature-sensitive, the room should be maintained between 65- and 85 degrees Fahrenheit for optimum effectiveness.

Green Glue is an excellent soundproofing material, although it is only suited for inside use. Both the Green glue compound and sealant are temperature-sensitive.

As a result, exposure to severe temperatures will make the material useless. Since outside temperatures cannot be regulated, Green Glue is not intended for outdoor applications.

Green Glue Company creates noise proofing products. There are currently four products offers by the company. They include noise proofing compound, noise proofing clips, noise proofing sealant, and noise proofing joist tape.

  • Noiseproofing compound is a sound damping product best used in renovation projects and new construction. It’s a viscoelastic compound that converts sound energy into heat.
  • Noiseproofing sealant– is used to fill joints and gaps where the wall meets the ceiling or floor or where two walls meet. It’s the finishing touch needed after applying the green glue noiseproofing compound.
  • Noiseproofing clips- they are used to separate two sides of a wall. In that case, when sound hits one wall, the energy isn’t transferred to the other wall. This prevents sound from transferring between walls.
  • Noiseproofing joist tape- if you’re often disturbed by squeaky floors and loud thunderous footsteps, joist tape will help you fix this problem. It creates a seal hence reducing unwanted noises.

Green Glue Sound Transmission Class

Green glue improves the sound transmission class of a structure by 10+ points depending on the construction assembly.

Independent tests have shown that Green Glue is one of the most effective soundproofing materials now on the market. Third-party acoustics studies found an STC value of 56 for a basic single wall with ordinary drywall & green glue.

Water-based polyurethane is a milky substance that dries to crystal clear.  It’s perfect if you need to preserve the color of your wood.
