Green glue is a firm that produces excellent soundproofing material. It is used on various construction projects, including new and renovation ones. Most of its items are made from a viscoelastic damping compound, which efficiently isolates without hardening. This property ensures exceptional dissipation of the vibrations caused by various sound waves.

Typically, this compound changes sound energy into heat, reducing noise levels. However, it is best when used to dissipate low-frequency noise. You’ll also use it between two surfaces, especially drywall, plywood, or cement board.

You can choose from various soundproofing materials offered by green glue: sealant, clips, joist tape, and compound. Green glue noise proofing compound is applied on various surfaces, including on new constructions and renovations.

You’ll use the green glue noise-proofing sealant to cover the gaps and joints on various surfaces. Mainly, it is applied where the ceiling meets the wall. Green glue noise-proofing clips come in handy when separating two sides of a wall. This way, it becomes hard for sound to get transferred from one wall to another.

If you want to avoid squeaky floors, green glue noise-proofing joist tape will be the best choice. It provides a seal that significantly minimizes unwanted noises.

What Does Green Glue Do?

Green glue is an excellent sound damping material used to reduce airborne noise. However, it is not the best choice for impact and structure-borne noise.

Advantages of Green Glue

Green glue soundproofing material comes with various benefits, including the following:

  • Excellent Sound Damping Abilities

Green glue comes with a unique polymer structure that converts mechanical energy to heat energy, dissipating vibrations. So you can rely on it to eliminate structure-borne, flanking, and slight impact noise. In addition, it assures you of up to 70% effectiveness, which is significantly high.

  • Affordability

Everyone lives on a budget, whether tight or flexible. Fortunately, green glue is relatively less costly, making it an ideal choice for people of various budgets.

  • No Wall Removal

You don’t need to remove existing walls to apply this green glue.


You can use green glue on various surfaces, projects, and places. First, you’ll need to sandwich it between two surfaces or sheets of building materials. Here, it absorbs noise from either side. That means you do not need to worry about removing the existing walls or floors. You can also use it on different surfaces, thanks to its versatility.


Green glue assures you of incredible performance, reliability, and durability. It guarantees you up to 70% muffling abilities. Further, its polymeric construction can convert mechanical energy to heat energy efficiently, dissipating the vibration energy.

Green glue is a reliable choice, attracting various positive reviews from across many regions. It offers you excellent soundproofing abilities, especially in places with low-frequency sounds.

Its performance peaks after about 30 days. This period allows any moisture and water in it to evaporate. However, this performance will depend on the room temperature. It’s working best when the temperature is in the range of 65 to 85 degrees Fahrenheit.


Despite its multiple advantages, this product comes with a few drawbacks.

  • Not ideal for high-frequency sounds
  • It is not available in all regions across the world
  • Temperature fluctuations make it less suitable for exterior use
  • It is not ideal for relatively soft materials

Green Glue STC Ratings

Green glue boasts relatively high STC ratings, meaning that it allows very little noise to travel between two surfaces or rooms. It has an STC rating of about 60, which is impressive. Also, it adds approximately 10 STC points to walls of similar weight, lowering the decibel rating to about 12 dB.

Leading Green Glue Alternatives

How about if you do not get green glue in your locality? In such cases, the following options will suffice.

Polyurethane Loctite

Polyurethane Loctite is a high-performance adhesive that offers excellent soundproofing potential. This adhesive can cover up to twice the ability of conventional choices. Its superior bonding allows you to use it for your interior and exterior alike.

Installing this adhesive is relatively straightforward. It requires you to cut the tip and puncture the inner seal. This way, you can apply the glue with a caulk gun. After that, leave it for between 15 and 20 minutes to dry. For its complete cure, you’ll wait for approximately 24 hours.

This product assures you of steadfast soundproofing abilities too. However, you must install it properly to get the best results. You could also apply multiple layers for excellent soundproofing potential.

Acoustic Sealant

From its flexibility to its affordability, an acoustic sealant is a relatively popular choice. It is designed for use on joints that sit between two soundproofing materials. For instance, you can use it between two cement boards or two drywall panels.

You cannot go wrong by buying the Everbuild AC504, thanks to its enhanced flexibility. This product is also paintable, meaning that you can blend it into your interior décor. It is non-flammable, mold-resistant, and can adhere to various surfaces.

Imperial Sealant Silicone

If you are looking for a flexible and waterproof silicone sealant, this will be your best bet. It works for new construction and renovation projects.

It offers excellent sound dampening, damping the vibrations traveling through various walls and surfaces. Besides being waterproof, this item can withstand extreme temperatures. This makes it perfectly suitable for all weather conditions.

The manufacturer suggests that you wait for about seven days for complete curing. At this point, you are sure of unrivaled performance and even consistency. What’s more, you can use this silicone sealant with all-temperature guns.

Mass-Loaded Vinyl

Mass-loaded vinyl is a thin and dense rubber material used to dampen noise between surfaces. Its versatility allows you to use it on various walls, adding mass and STC ratings.

The TMS Sound Proofing Padding is an effective alternative to green glue. It boasts premium-quality material, meaning that you get unrivaled performance. Also, none of its materials are re-grinded or recycled, enhancing safety.

This product offers dual functionality, meeting your needs and balancing mass optimally. It also helps a relatively quiet environment, working on surfaces and machinery enclosures. Mass-loaded vinyl is easy to install, demanding no additional costs or skills.
