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.

This Drywall stands out for several reasons.

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.

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 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.

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.
