How effective is Green Glue for soundproofing?
The result is dramatic - just one layer of Green Glue Noiseproofing Compound in between two sheets of drywall can eliminate up to 90 percent of noise, even at low frequencies.
How much STC does Green glue add?
10 STC pointsGreen Glue transforms the sound isolation of common wood stud walls from poor to excellent. For walls of the same weight in this comparison, Green Glue adds 10 STC points and improves low frequency performance by as much as 12 dB.
How do you use Green Glue soundproofing sealant?
0:231:47Applying Green Glue Noiseproofing Sealant - YouTubeYouTubeStart of suggested clipEnd of suggested clipWhen ready to begin tap your tube of sealant on a hard surface to bring compound away from the tipMoreWhen ready to begin tap your tube of sealant on a hard surface to bring compound away from the tip to prevent. Dripping. Cut a 1/4 inch hole in the tip of the tube with a utility knife.
How much of a difference does Green glue make?
Green Glue improves the performance of metal stud walls considerably. For walls of the same weight in this comparison, Green Glue adds 9 STC points and improves low frequency performances as well. Results: Green Glue easily outperforms these 2 types of factory-damped drywall, especially at low frequencies.
How long does Green Glue last?
1 yearThe published manufacturer's shelf life of Green Glue Noiseproofing Compound is 1 year however if properly stored the compound should last much longer than that. The easiest way to determine if material has gone bad is to dispense a tube and check for its consistency.
Is Green Glue better than MLV?
At the primary low frequency resonance (around 80Hz or so), the Green Glue wall outperforms the MLV assemblies by as much as 9dB – the equivalent of tripling the mass of the wall. Over most of the vocal/speech frequency range, the Green Glue assembly outperforms the MLV assemblies by 10-15 dB.
Can you use too much Green Glue?
No. Green Glue needs to be a constrained layer, meaning that Green Glue is sandwiched between two rigid, dense layers of building material. There is no limit to how many drywall / Green Glue layers you can utilize, and performance will improve as the # of layers goes up.
Is Green Glue permanent?
Despite the Green Glue name, our Noiseproofing Compound is NOT a permanent adhesive and therefore the second layer of drywall still needs to be fastened to the studs per local building codes.
How long does it take for Green Glue to set?
Allow Green Glue 30 days of drying time for optimal sound isolation performance. Because it needs to dry, Green Glue must be allowed 7 to 10 days drying time before sound isolation will start to improve. High humidity, cold temperatures and multiple drywall layers could slow the drying time considerably.
How much thickness does Green glue add?
about 0.5 mmGreen Glue has been specially formulated to “squish” the large beads into a thin layer (about 0.5 mm). It is usually more convenient to apply Green Glue to a loose drywall sheet at floor level (or sawhorses) and then raise the panel.
How effective is double drywall with Green Glue?
A double layer of drywall with Green Glue installed on one side of the same wall will give you an STC of approximately 45 (compare that to 2-3 points achieved with insulation, MLV or just another layer of drywall) a 2nd layer of drywall with Green Glue on the other side will give you an additional 4-5 points, bringing ...
Can Green Glue be removed?
Take precautions such as drop cloths and latex gloves when using Green Glue. Take care to remove the Green Glue from unwanted surfaces before it dries. Use 70% Isopropyl Alcohol to clean up Green Glue.

How much Green Glue should I use?
How much do I need? Recommended application is 2 tubes of Green Glue per 4' x 8' area - 2 tubes per standard sheet of drywall. If you are not on a budget, utilizing 3 tubes per sheet will improve performance. Each case of Green covers about 192 square feet, or 128 square feet if used at the 3 tubes coverage rate.
What are three 3 methods of increasing the STC rating of a wall assembly?
Top Ways to Increase Wall STC:Higher Gauge: By moving to lighter gauge stud, such as 25-gauge, the flexibility of the wall greatly improves. ... Space Out Studs: Move studs from 16″ o.c. to 24″ o.c., where possible. ... Increase Depth of Studs: 6″ 25-gauge studs may offer 3-4 STC point improvement over the same 3-5/8″ stud.More items...•
What is Green Glue?
Green Glue is a brand name for a type of noiseproofing compound. This is how the company refers to it, but it’s essentially acoustic caulk.
Why does green glue stop sound waves?
Sound waves vibrate through the surface but are stopped by the Green Glue because it remains elastic.
How long does it take for green glue to work?
Again, this isn’t a major con, but Green Glue takes about 30 days before it’s completely effective.
How to use green glue?
For the most part, using Green Glue is as simple as pointing it at the surface and squeezing the trigger.
Where to apply drywall sealer?
For best results, apply it to the rear of a drywall sheet and then seal any gaps between sheets.
What energy is converted to heat energy?
In turn, the vibrational energy is converted to heat energy, as it expends its force trying to make the Green Glue’s molecules vibrate.
Is green glue good for sound?
Not only is it ideal for sealing small gaps between materials, which sound can pass through, but it’s also great at dampening low-frequency sounds. It does this by converting them into heat energy.
