Whats up with that Green Glue Stuff???

The Soundproofing Industry is all a buzz about a new soundproofing product called, oddly enough, "Green Glue". Green Glue is a visco elastic dampening compound that isolates one sheet of drywall from the other. Green Glue is applied directly to the back of a new sheet of drywall that will be screwed up to existing drywall that is already up on existing walls and ceilings. No need to demo your walls and ceiling to soundproof. Green glue acts as both an isolator and a dampening material that deadens the joist or stud structure but at the same time isolating the newly installed drywall from the existing drywall and structure assembly. The longer the Green Glue has to cure the better the results you will achieve.
Green Glue can also be used on sub floors for impact protection from hardwood or ceramic tiles floors in upper units. The Green Glue is applied to the floor with a standard large caulk gun and you simply squirt out the Green Glue in an "S” pattern as evenly as possible prior to placing down the second sub floor and then finally installing a wood or tile floor. Green Glue is a superb sound insolator and will stop the majority of both impact noise and airborne noise from traveling down to the unit below. Green Glue is revolutionizing the soundproofing industry and Soundproofing America is proud to be at the fore front of this revolution and please to introduce Green Glue to the public.

STC Principals Explained

The Truth About STC
The best place to start is with a discussion of the ever-present STC system. If you've done some looking into sound isolation, you have probably seen STC ratings for different walls. If you click the
Understanding STC link, you will get some discussion of STC - what it is, and more importantly, what it isn't. STC has one huge problem - it completely ignores low frequency performance. As a result, for most applications, STC is not a good indicator of performance, and you shouldn't rely on it. Understanding STC. But before you get started reading about STC, make sure to check out this short page about “Transmission Loss”, and how to read the graphs you see.
The Basic Principals Involved in Sound Isolation / Soundproofing
Rather than looking blindly at STC ratings, this section of our site will look at overall wall performance. And, what better place to start than with some discussion of the
Five Basic Principals of Soundproofing / Sound Isolation - the 5 things that can help your walls stop more sound. From there we'll look at the Four Basic Ways to Improve the Performance of a Wall.
Resonance and the Low Frequency Performance of Walls
Often low frequency performance of walls is lost in the shuffle of discussions revolving around STC. We take the most thorough look at the low frequency performance of most common wall types in a careful and systematic way. We believe that the data contained herein is the fruit of the single largest full-range (31.5hz) study on walls to date.Read:
Effect of Insulation in the Common Walls
New Construction
If you want to just cut to the chase, and see how different walls perform, or if you want to see those Principals in action, check out
this page, which steps you through the performances of different walls that you can opt for in new construction, complete with lab data.
Remodeling and Upgrading an Existing Room
If you have a situation where you want to soundproof an existing wall or ceiling, we will take you through the options available to you in upgrading what already exists, complete (again) with lab data. Working with what you have can save a lot of money that would otherwise be spent tearing down, and replacing, what you already haveRead:
Updating Existing Walls SoundproofingRead: Upgrading Existing Floors Soundproofing
No Partition is Better than its Weakest Link
For some situations, the choice of main wall (or floor/ceiling) construction + consideration of flanking noise is enough. However, for partitions that are to include windows or doors, the performance of those items must also be considered. We'll take a look at the impact of these kind of things on overall performance, and step you through how to get the most bang for your buck (or to reach the absolute performance you desire).Read:
Tend to the Weakest Link in your Soundproofing Chain
Flanking Noise
While choosing a wall is very important, it’s only part of the process. You also have to deal with noise that, for example, reaches an upstairs room via a path other than the floor/ceiling. Examples of such noise paths would be into the walls and up the structure, through ductwork, etc. Our flanking noise page will let you plan for all of these potential problems.Read:
Understanding Flanking Noise
Impact Noise/Footstep Noise
Those ever-annoying upstairs neighbors. Here we take a look at the basic possibilities that exist with respect to taming impact noise.Read:
Understanding Impact Noise
That Should Cover it!
We’ve covered the Principals that affect isolation, how they interact in real walls, how to choose a construction to meet your needs, upgrading existing walls, dealing with flanking noise, and how to deal with typical “weak links” like doors and windows. And we’ve taken a one-of-a-kind look at the low frequency performance of walls in a way that has never been done before.
Good luck, and don’t hesitate to write with feedback or specific applications.

The Green Glue is here and ready for immediate delivery

Soundproofing America now has the Green Glue in stock and ready for immediate delivery!! This revolutionary product has set the standard for the soundproofing industry. Green Glue is a visco Elastic Dampener that is applied between layers of sheetrock. The glue acts like a resilient barrier and allows the sheetrock to resonate or move much like a floated wall or ceiling. The Green glue also isolates the new layer of drywall from the old drywall and the structure. This isolation is the same, as you would find in a floated ceiling or wall. The Green glue is easier to ship and gives you the same soundproofing as mass loaded vinyl or even lead.
Green glue is also quite effective at blocking low frequency sound. Low frequency sound reduction is what most people are looking for in a soundproofing product. Green Glue is excellent at stopping low frequency noise from passing through walls and ceilings and is also a great product to use on floors in conjunction with to stop both airborne and impact noise from passing through and going down to the neighbor below.
For some outstanding soundproofing call the pros at Soundproofing America and ask them about Green Glue.
