Green Glue is one of the best-known soundproofing sealants on the market.
However it’s certainly not the cheapest and, due to its popularity, is often out of stock.
If you’re looking for a good green glue alternative then we recommend you try one of these:
- Auralex Acoustics STOPGAP
- TMS Acoustic Caulk
- Titebond Acoustical Sealant
- OSI Acoustical Sound Sealant
- Dynaflex 230
- Gorilla Heavy Duty Mounting Tape
- TMS Acoustic Putty Pads
- Noiseproofing Joist Tape
1. Auralex Acoustics STOPGAP
Auralex Acoustics know what they’re doing when it comes to soundproofing.
Their STOPGAP sealant is made specifically to reduce sound transmissions and is believed by many in the trade to be a more effective soundproofing sealant than Green Glue.
STOPGAP is water-based which means it is non-hazardous so can be used near food preparation areas. It is also non-flammable so is safe to use to seal around electrical outlets.
It gets it’s great soundproofing properties from its extreme elasticity which makes it incredibly effective at dampening soundwaves whether they are airborne or traveling through walls or flooring materials.
Be aware that this is sold in a 29oz tube which is bigger than the standard tube sizing so you may require a larger caulking gun to use it.
This highly rated product is roughly 30% more expensive than Green Glue though so if you’re looking for a cheaper alternative keep reading.
2. TMS Acoustic Caulk
TMS Acoustic Caulk is a latex-based sealant that is effective at stopping airborne noise from traveling through gaps.
It can also be used beneath floors to help dampen noise traveling through floor surfaces into floor joists.
Latex is an effective soundproofing material that is famed for its tensile and elongation ability.
In other words, it is highly flexible which means this caulk is great at dampening any vibrations that hit it.
It is roughly 15% cheaper than Green Glue per tube so if you’re using a lot the savings will quickly add up.
3. Titebond Acoustic Sealant
Titebond Acoustical Sound Sealant is a great value Green Glue alternative.
It is purpose made for improving sound transmission class ratings for walls and flooring (exactly what Green Glue does).
This easy apply sealant can be painted and is highly resistant to mold and mildew.
It also doesn’t harden up as it ages which means it retains it sound dampening properties for years.
It is completely non-hazardous and environmentally safe to use being non-flammable, free of plasticizers and VOC compliant.
It is roughly 40% cheaper than Green Glue.
4. OSI Acoustical Sound Sealant
OSI Acoustical Sound Sealant is another purpose-made sealant designed to help improve sound transmission class ratings by dampening sound waves in places such as partition walls.
This U.S manufactured sealant is water-based making it completely non-flammable and therefore safe for use in places such as electrical boxes.
Be aware this product does contain a very small amount of volatile organic compounds (VOC) at a ratio of 25 grams / Litre (less than one percent) so a mask should be worn when applying it.
This paintable sealant gets its soundproofing qualities from its incredible flexibility which it retains after it has cured.
It even remains flexible when exposed to extremely cold temperatures.
At approximately 75% cheaper than Green Glue this is a winner if you are looking for an effective budget friendly alterantive.
5. Dynaflex 230
DAP Dynaflex 230 is another latex-based sealant that is mold-resistant.
It is made as a waterproofing sealant for tiles, shower cubicles, baths, sinks, etc.
However the latex does also does a great job of dampening air borne sound.
Be aware that Dynaflex 230 will shrink down as it hardens after application so ensure that you use it fairly liberally to prevent gaps appearing.
It is roughly 60-70% cheaper than Green Glue per tube however be aware that it is primarily a waterproofing sealant rather than an acoustic sealant.
6. Gorilla Heavy Duty Mounting Tape
Gorilla heavy-duty mounting tape obviously isn’t a sealant however it is actually a very effective green glue alternative.
Due it’s density it does a good job of helping to dampen vibrations.
It is also very strong meaning you can use it to effectively ‘glue things up’ and hold them in position.
It is very easy to apply on partition wall studs and is a very effective way of dampening sound from traveling through walls and studs, you can also do the same with floor joist and floorboards.
Obviously you can’t really use it to seal up holes around door frames as it won’t look great however depending on the type of job you are working on Gorilla tape could be a great alternative option.
It is roughly 50% cheaper than a tube of Green Glue sealant.
7. TMS Acoustic Putty Pads
If you need to properly and professionally seal up and electrical box then you can’t go wrong with these acoustic putty pads.
While you can use a non-flammable water based sealant you will get a much better seal using a putty pad.
These pads are capable of withstanding fire for up to two hours and you can always double them up for extra fire proofing.
It has an decent sound transmission class rating of 49. Meaning that it is an effective soundproofing material so could also be used to seal up other areas where noise may leak through.
These are roughly the same price as a tube of Green Glue, if you are doing the specific job of sealing up an electrical box then this is a better option all round.
8. Noiseproofing Joist Tape
It is common to use green glue on joists so that when the floorboards are laid down impact noise such as footsteps is dampened.
This tape does the same job but without the mess of having to use glue.
It can also be used in stud walls.
It will make your home quieter, getting rid of floorboard squeaks as it reduces impact sound transmission through floor joists.
The spongy closed-cell foam is resistant to mildew so it can be used under floors that may be exposed to damp.
It is significantly more expensive than green glue at roughly 3x the cost, but if you want something that is mess-free and specifically designed for the one job of reducing sound transfer through floors then this is a perfect choice.
Choosing A Green Glue Alternative
Green Glue is loved by everyone from soundproofing professionals to D.I.Yers.
Its enduring appeal is due not only to how effective it is but also how quick and simple it is to apply and how versatile it is.
It can be used on ceilings, walls, floors, door frames, window frames and more.
It’s therefore no surprise that it has become one of the most popular soundproofing materials available.
The only reason why some people may hate Green Glue is that it has a particularly bad smell when it is being applied (fortunately the smell quickly fades once it has dried).
If you can’t tolerate the smell then an alterantive is essential.
When most people talk about Green Glue they are talking about their Noiseproofing Compound which comes in tubes. However, Green Glue also sell their glue in giant 5-gallon buckets (ideal for huge projects) and they also make floor joist tape too.
For the purposes of this article, we assumed that you were looking for an alternative to their standard noise proofing compound in tubes.
While Green Glue is considered to be the best soundproofing sealant it is clear that there are plenty of alternatives available that are more budget-friendly or are better suited to specific jobs.
We hope this article helped you find a good alternative that works well for your project.
