8 Best Alternatives to Green Glue

1. Auralex Acoustics STOPGAP

Best Overall

Auralex Acoustics STOPGAP

Taking the spot for the best Green Glue alternative is the STOPGAP Acoustical Sealant by Auralex Acoustics.

This highly elastic and water-based sealant STOPS noise from bleeding out of the walls they’re treated with.

Is It Right for You?

If you’re looking for a flexible and easy-to-use acoustical sealant, then the STOPGAP sealant is the alternative you’re looking for.

Here’s why:

  1. It dries to a tough film and stays as a flexible compound for up to 5 TIMES longer than others of its class! Amazing, right?
  2. STOPGAP has a sound transmission class (STC) of up to 53 by applying two beads of sealant at the top, bottom, and all edges of perimeters, giving you effective sound isolation.

Now take note!

A higher STC rating means better sound isolation.

Keep in mind you’ll need a caulking gun to apply this water-based product. It is also a bit more expensive than Green Glue (on top of the caulking gun you have to buy), but we think the price is well worth it!

2. TMS Acoustic Caulk

Best Value

TMS Acoustic Caulk

TMS Acoustic Caulks screams VALUE.

You’re looking for the pot of gold for noise-proofing compounds, but Green Glue is somewhat an inch short of the mark.

You’re frustrated, and we get it. So have you tried latex?

Here’s a fun fact for you: Latex is a well-known sound-dampening material with tensile and elastic properties that absorb sound transmission.

Is It Right for You?

Think about it this way:

  • It’s cheaper than Green Glue.
  • It keeps draft and smoke away from slipping through tiny gaps.
  • You can apply this sealant to wood, drywall, concrete, etc.
  • And finally, TMS Acoustic Caulk’s high-quality latex formulation is like a big red traffic light that stops soundwaves and sound transmissions from entering the room.

How’s that compared to your average Joe Green Glue compound?

Maximizing the value in your purchases is the ULTIMATE game, and we think you can’t go wrong with this noiseproofing compound.

We highly recommend this as a substitute for Green Glue sealant!

3. OSI 175 Acoustical Sound Sealant

Best Budget Pick

OSI 175 Acoustical Sound Sealant

Blocking sound waves on a budget is possible, FYI.

The OSI SC175 Acoustical Sound Sealant may be cheaper, but this product provides incredible support in your journey to stop noise transfer dead in its tracks.

This low-cost alternative is an acoustic sealant that DAMPENS sound energy from perimeter edges like wall partitions, dry walls, and the like.

Now here’s the chocolate to your sundae:

OSI 175 maintains FLEXIBILITY regardless of cold temperatures!

Is It Right for You?

Thinking of blocking sound waves on a budget with sealant?

This low-cost sealant from our list of alternatives to Green Glue is chump change you can easily spend for.

A double bead of this product on perimeter wall edges can help you achieve a sound transmission class (STC) of 55, making it IDEAL in sound-blocking, among other materials.

If you’re a beginner, please mind the following disclaimers:

  • This alternative to Green Glue does contain a small amount of volatile organic compounds (VOC). So please, don’t forget to wear a MASK.
  • You’ll also need a strong quality caulking gun to push this out. Why, you ask? Because this one’s THICK. It’s best to consult a professional before applying to posts, a wall, etc.

But other than that, you can reach great results for this significantly cheaper alternative.

Better say goodbye to sound transmission!

4. QuietGlue Pro

QuietGlue Pro

As an amateur in the world of soundproofing materials, it can be confusing.

Finding a beginner-friendly noiseproofing compound that compares to Green Glue can be a tad bit overwhelming.

But you’re not alone!

Quiet Glue Pro should be one of your go-to alternatives to Green Glue.

This easy-to-use glue compound is a low odor & water-based compound ideal for quick fixes to avoid sound transfer in renovation projects.

Are you amazed yet? Keep reading and ask yourself:

Is It Right for You?

You can’t go wrong with an easy fix and up to 55 STC!

Keep in mind, though, this compound doesn’t harden as quickly as the other Green Glue alternatives in this list.

But hey, if you’re looking for a quick solution to patch up your wall or door, this water-based alternative to Green Glue sealant is the one for you!

5. Quietrock Soundproofing Drywall

Quietrock Soundproofing Drywall

Among other Green Glue alternatives, this one’s different. Maybe you’re looking for easy-to-use drywall layers?

Or you just want to avoid the messy image of your clothes dirtied up with glue compounds?

Save yourself from that embarrassment!

This acoustic drywall is one of the best alternatives to the Green Glue noiseproofing compound!

The Quietrock Soundproofing Drywall is a gypsum drywall designed to reduce noise transfer across walls.

It features an assortment of thicknesses, ranging from ½” double layers up to a five-layered 1 3⁄8″.

It works like your own personal force field that keeps sound in!


Is It Right for You?

You might prefer gypsum panels over acoustic glue compounds if you want to stop sound transmission among the walls of your room.

This can be ideal for apartment buildings or even your work environment!

However, we think you should also be aware that this product isn’t ideal for ceilings.

But still…

If you just intend to soundproof your walls, watch that 52 STC rating work like a magic material!

6. Mass Loaded Vinyl

Mass Loaded Vinyl

You may be considering your options and want to try vinyl treatment materials instead.

In that case, we got your back!

Mass Loaded Vinyl is an excellent noise-blocking green glue sealant alternative to trap the sound from leaking outside your wall.

Mass Loaded Vinyl is composed of dense materials and can be installed between the layers of drywalls. Another pro is you can get creative with this and cover it with latex paint for that finishing touch.

Is It Right for You?

Maybe you’re thinking about minimizing the sound of your EPIC DRUM SOLOS from leaking out of your studio?

Or maybe you just want a good fix to treat your room for making video content?

But you can’t find any Green Glue Noiseproofing Compound, huh?

Then this is it!

The Mass Loaded Vinyl is a flexible alternative that offers various STC ratings of 20-33, depending on the thickness.

You can get them at variations of 4’x10′ and 4’x25′ rolls, as well as 4’x4′ squares. Convenient, right?

Although it can be a more expensive route, we still highly recommend this Green Glue alternative.

It can even complement the aesthetics of your room!

7. Imperial Silicone Sealant

Imperial Silicone Sealant

If you’re thinking about soundproofing your new construction and renovation projects, we recommend the Imperial sealant.

Silicone is a solid material option to make tight spaces and corners soundproof.

GREAT NEWS: It’s resistant to water and UV rays, as well!

Is It Right for You?

While the product ISN’T SPECIFICALLY made for acoustic treatment, this can still be a great substitute from our list of alternatives to the Green Glue compound.

Aside from using the product as a utility sealant, you can soundproof your room with it, too.

Just put the work in and let it cure for a week to achieve ideal results.

Talk about multifunctional, right?

8. Polyurethane


Polyurethane is another well-known substitute for Green Glue noise proofing compound.

Unlike the usual acoustic sealant, this product is a varnish made of a resin material that firmly bonds upon drying.

For something we commonly associate with home furnishings and beddings, you’d be surprised that polyurethane can lead to an amazing result for sound isolation, as well!

Is It Right for You?

Applying polyurethane to wood surfaces not only improves the look of the wall but also improves its acoustics!


This is a polyurethane varnish material, so high amounts of polyurethane exposure can lead to respiratory issues!

Polyurethane effectively diminishes high-frequency sounds but doesn’t provide much for low frequencies, so that’s something to keep in mind.

What Is Green Glue Noiseproofing Sealant?

After going through our top recommendations for other noise-proofing substitutes in this article, you must be curious:

Does Green Glue even work? What’s the hype about it?

We thought of giving you a little intro to the product, so you know what Green Glue is all about!

The Green Glue Company was formed out of necessity in 2003 to achieve the ideal sound isolation by Ted White and his buddy, Brian Ravnaas.

The concept was to insert a damping layer into the construction materials, and they found out the best results were achieved by damping drywall with a semi-liquid paste, a noise-proofing compound.

Thus, the GREEN GLUE noiseproofing compound was BORN!

The product enjoyed success in the noise-proofing and audio world and spawned the development of their products:

  • Noiseproofing Sealant
  • Noiseproofing Compound
  • Noiseproofing Clips
  • Joist Tape

Currently, Green Glue is available in some territories WORLDWIDE, from Alaska to New Zealand!

Why You Should Start Soundproofing

Perhaps you’re an audiophile who wants to achieve the proper isolation or just someone who appreciates uninterrupted privacy.

You have to admit it, too. Noise can be a NUISANCE!

We’re here to tell you that soundproofing is the magical solution to get the most out of the space you’re in, and here’s why!

1. Privacy is Prime

First of all, soundproofing your home is the best level of security, after the locks on your doors.

Maybe you just want to have more silence when doing school projects?

Or you just don’t want your neighbors snooping on private conversations from inside your walls.

We promise it’s the way to go!

2. Health in Hearing

As much as too much sound is bad for the environment, it can be bad for your sense of hearing, too.

A prolonged period of noise above 70-120dB is without a doubt harmful.

Consider soundproofing to save your ears!

3. Home and Comfort

Imagine this: it’s 11 PM on a Sunday.

You’re sitting at your home theater, enjoying your favorite action movie, but then you realize it might wake up other people in the house.

Bummer right?

With soundproofing, you won’t have these troubles at all, and you can enjoy the surround sound as much as you want!

4. Local Regulations and Concerns

Perhaps you live in a place where there is strict enforcement of sound regulations.

We swear, going soundproof is a logical consideration. Keep the sound within your wall!

5. Future-Proofing Construction Plans

It is common practice these days to consider soundproofing materials in construction plans for a new home.

Don’t be afraid to ask your architect and engineer to apply it to the building plan and consider putting polyurethane panels on the walls.

It’s a worthy investment for acoustics and aesthetics!

DIY Soundproofing Tips

The overwhelming image and thought of soundproofing material costs from high-end services can be DAUNTING, without a doubt!

But of course, you know we have your back, right?

We have some quick tips for you to DIY here!

  1. Adding some soft items like a carpet help reduce vibrations and ambient noise.
  2. Applying some layers of gypsum panels behind speakers and TVs works wonders.
  3. Apply acoustic sealant (like Green Glue sealant and the ones we listed above) to seal off small cavities under doors and walls.
  4. Adding joist tape helps create a seal to reduce unwanted noises like footsteps.


While Green Glue truly is an effective choice for your soundproofing needs, there’s a lot of options in the market to choose from as well.

We highly recommend the STOPGAP from Auralex Acoustics.

But if you’re looking for specific products to fit your needs, our other recommendations can WORK WONDERS as Green Glue alternatives.

We hope you enjoyed reading, and we bid you well on your road to acoustic bliss!
