In this article, I’ll be guiding you through some of the best green glue alternative materials you can get on the market today.
However, before we get to that, let’s first familiarize ourselves with green glue compound.
Green Glue is a product known for its outstanding soundproofing properties.
The compound works by isolating sound waves to not travel through mediums like walls, ceiling, and floors. It can be great for sealing garage door.
Types of Green Glue Compounds
Green Glue comes in different formats. These include:
Noise proofing compound – This is a viscoelastic compound that changes the sound energy into heat, hence providing soundproofing properties.
It can be used for sound-dampening in both new construction and renovations.
Noise proofing sealant – This product is used for filling gaps and joints where a wall meets the floor or ceiling, or two walls meet.
You can use the sealant for a more flawless finish after applying the noise proofing compound.
Noise Proofing Joist Tape – This product is designed to take care of squeaky floors.
If you can hear thunderous footsteps from different parts of your home, the Joist Tape will create a seal against these unwanted noises and take care of your problem for good.
Noise proofing Clips – These are used to separate adjacent walls.
They work to prevent the transfer of sound between walls by keeping them separated.
A-List of 7 Green Glue Alternative
If green glue isn’t available in your country or simply want a great alternative, then below are some of my recommended green glue alternatives you can get on the market today.
1. Loctite Sealant
This is a urethane-based adhesive that is high performing and environmentally safe. The adhesive will cover twice the area covered by conventional adhesive.
It helps that it is also three times stronger. The adhesive works great for both interior and exterior projects
It is ideal if you are looking for a good adhesive for the installation of subfloors.
Since it is waterproof, you are guaranteed that the surface you use it on is protected from water damage.
With the Loctite sealant, the surface is also abrasion and solvents resistant.
Such surfaces are also able to handle impact better compared to those where conventional sealants are used.
After applying the Loctite Sealant, you can easily paint over it.
It helps that the adhesive also cures in cold temperatures and can be applied even on wet and frozen wood.
2. QuietRock Soundproof Drywall 500
This Drywall stands out for several reasons.
One, it is thin, making it easy to handle when compared to gypsum walls. You do not need any tools to install this product on your surfaces.
The QuietRock 500 also delivers considerable acoustic performance, and the good thing is that it doesn’t take too much of your floor space.
Additionally, this product not only exceeds the STC requirements of a variety of wall applications, but it also outperforms several gypsum layers.
You can use the QuietRock Drywall on new buildings and during renovations. The Drywall is recommended for walls, but use on ceilings is discouraged.
The QuietRock 500 is an ideal investment if you are looking to soundproof your walls with minimal alterations on size.
Application is easy, and the product remains highly reliable.
3. TMS Soundproofing Barrier
This product is perfect for apartments, studios, medical facilities, and classrooms.
It can also be used in automobiles, making it one of the most versatile barriers available.
The barrier is made using extruded virgin material, so you are guaranteed that the quality is top-notch.

This US-made barrier is also massive when compared to similar products.
Its performance is unrivalled, and because of its overall construction, the barrier is sure to stand the test of time.
The TMS soundproofing barrier that is about an eighth of an inch in thickness has an STC value of 27 when it is hanging by itself.
This rating will only go up when it is used against a wall, the floor, or on your ceiling.
4. Everbuild AC50C4
The Everbuild AC50C4 is a permanently flexible and high-strength acoustic sealant specifically designed to bond and seal plasterboard, among other kraft-lined boards.

This adhesive is also known to be non-flammable and mould-resistant.
The fact that it also adheres to a variety of surfaces makes it the ideal adhesive if you are looking for a versatile product.
For best results, cut the nozzle at least 4.4mm wide so the opening will regulate the amount of pressure.
Anything smaller will mean that the pressure is too much, and some of the sealants may ooze on unintended surfaces.
5. Dap DYNAFLEX 230
The Dap DYNAFLEX 230 is a premium door, window, trim, and siding sealant.
This sealant is perfect if you want to block draft, keep moisture out of your space, and prevent invasion by pests.

6. Auralex Acoustics STOPGAP
The Auralex Acoustics is a viscoelastic sealant just like Green Glue. When applied to gaps in windows, electric fixtures, and walls, the sealant works to reduce soundwaves transfer.
The Auralex sealant is also water-based.
While you still need to cure the sealant to get the best out of it, you will enjoy five the times of elasticity you would have gotten with a similar soundproofing sealant.
Applying this sealant is easy, and there is no risk of creating runoff. While the sealant has a slight odor, the smell disappears when it is well-cured.
