Description

Green Glue is a non-toxic, low-VOC, visco-elastic compound that can be quickly and easily applied between two sheets of drywall, plywood or any commonly used building materials in new construction and remodeling. It effectively reduces noise transfer from one room to another.


Features / Benefits

Economical — Costing about 80 cents per square foot, a layer of Green Glue is the most economical sound isolation product around, as well as one of the best.

Ease of Installation — Since Green Glue is intended to be sandwiched between two sheets of building materials such as drywall, it eliminates the need to remove existing wall and floor materials. Because of its thin consistency (like ketchup), a tube of Green Glue can be easily dispensed in 15 seconds. Green Glue will not flow off a board when installing. No specific coverage pattern is necessary to ensure excellent results. No measuring or troweling. A larger tip opening (3/8” opening) can be used to speed application without concern for performance.

Environmentally Friendly — Green Glue Noiseproofing Compound is non-toxic, non-carcinogenic, and very low in VOCs (it's less than 5 grams per liter/compliant in all 50 states and worldwide). It does not contribute to mold growth and has almost no odor. Green Glue Noiseproofing Compound can be easily cleaned up while still wet with soap and water.

Excellent Flammability Rating — Green Glue Noiseproofing Compound has been validated for use in any fire rated assembly according to the International Building Code. Using Green Glue Noiseproofing Compound will not affect the fire rating of the area to which it's applied.

How Green Glue Works:

In a constrained layer damping system, sometimes referred to as CLD, a damping material is sandwiched between two other (usually stiff/center of the "sandwich" is sheared rigid) materials. For example, Green Glue sandwiched between two layers of drywall. Damping occurs when the viscoelastic center of the "sandwich" is sheared.

When bent, shear forces pull and stretch on the damping material. Under these conditions, the unique polymeric construction of Green Glue very efficiently converts this mechanical energy to heat. The vibration energy is not isolated, it's dissipated and gone.

Installation Details

Application Steps

After hanging the first layer of drywall, it is recommended to seal the seams between sheets. This can be done with either caulk or drywall mud. If using caulk, take care not to use a bead so large that it protrudes outside the plane of the drywall, preventing the second layer from sitting flat (below). If speed is an issue, omit this step and seal the perimeter after the last sheet of drywall is installed.

GreenGlueApplication

The above image is Correct - The caulking bead applied to the drywall seam is below the plane of the wall.

GreenGlueApplication

The above image is Incorrect - The caulking extends beyond the plane of the wall. This will prevent the next layer of drywall from contacting the first layer and lowering performance.

If using drywall mud, fill the seam and the indentation caused by the tapered edge of the drywall. A perfect finish is not essential, so a single broad swipe with the drywall knife should do. If speed is an issue, omit this step. Just hang the first layer, and move to the second layer.

GreenGlueApplication

The above image is Correct - A quick layer of setting type drywall mud is applied below the plane of the wall. This method also increases the area of contact between layers.

GreenGlueApplication

The above image is Incorrect - Avoid these types of protruding caulk beads and random spills/smears/drips of mud that extend past the plane of the first layer.

If using mud for the first drywall layer, make the first layer flat, smooth, and free of protruding bits of mud, caulk, or fractures in the drywall that might prevent the second layer of drywall from sitting flat against the first. Filling seams smooth with drywall mud can increase overall contact area and may slightly improve performance over caulk alone.

Opening the Green Glue tube

Acceptable tip openings range from 1/8” to 3/8”. We have researched coverage patterns and bead sizes considerably in our labs and have not found a dramatic difference among various techniques and choices.

Green Glue coverage

The ideal coverage should be uniform throughout the sheet using 1 - 3 tubes.

Applying 1 tube of Green Glue per 4’ x 8’ sheet will deliver about 70% of the performance of 2 tubes. Three tubes is optimal per 4’ x 8’ sheet and will improve low-frequency performance around the primary resonance. We do not recommend using more than 3 tubes per sheet. Using too much Green Glue will cause a decline in performance.

GreenGlueApplication

Above image, Yes – Uniform coverage gives desired performance.

GreenGlueApplication

Above image, Yes - Leaving 20% of the area uncovered while still using the same amount of Green Glue (1-3 tubes) will result in a marginally thicker film when the two sheets are compressed together. This will slightly improve low frequency behavior at a slight expense to higher frequency performance (the difference is small).

Leave border around material

Leaving a 2-3 inch border around the edge of the drywall or building material will allow for carrying the material without getting fingers into the Green Glue.

Leaving this border will not affect sound isolation performance.

Applying Green Glue

GreenGlueApplication

After application of Green Glue, use standard drywall screws to fasten the drywall to the studs. Green Glue has been specially formulated to spread 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. Press the building material against the wall or ceiling and then screw it to the studs.

If installation conditions prohibit Green Glue from being applied at floor level, it is just as effective to apply Green Glue to the first layer of drywall and raise the second sheet of drywall onto the wet surface.

Green Glue drying time

Do not let Green Glue Noiseproofing Compound dry before 'sandwiching.' Screw the top sheet of drywall/building material, and 'sandwiching' Green Glue, within 15 minutes of Green Glue's application. Drywall sheets must be screwed together while the material is still wet.

Allow Green Glue 30 days of curing 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.

Green Glue clean up

Take care to remove the Green Glue from unwanted surfaces while wet. Products that clean well are Avon Skin So Soft Bath Oil©, as well as citrus based solvents and cleaners such as Goof-Off©.


Installation

Tools Needed: Drill or Screw Gun, Level, Caulk Gun, Tape Measure, Pencil, Chalk Line (for large installs), Utility Knife (for cutting or trimming)

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 not under budgetary constraints, utilizing 3 tubes per sheet will improve performance. Each case of Green Glue Noiseproofing Compound covers about 192 square feet, or 128 square feet if used at the 3 tubes coverage rate. Do not use more than 3 tubes per 4' x 8' sheet as performance will actually decline above 3 tubes per sheet.

Please Note:

Green Glue is sticky! There is nothing harmful about Green Glue, but it is important to warn installers that it can be tough to clean up, especially after it has dried. 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. Products that clean well are Avon Skin So Soft Bath Oil©, as well as citrus based solvents and cleaners such as Goof-Off©.

Green Glue is not odorless. In the same way that a paint odor is present while painting a room, Green Glue has an odor while being applied. Most installers aren’t bothered by the smell, but it is nevertheless important to keep the room well ventilated to prevent a build up of odor. Cold temperatures or high humidity will slow drying. Smell will not linger on furniture, clothing or carpeting. Like paint, once dry, the smell will fade.

    I had enough of watching my walls shake every time my neighbor wants to listen to his music. I got in touch with Drew at Soundproof Cow and he gave me two suggestions. The one was a rail system that seemed like it would work but I couldn't use it because I would be losing too much space off my walls. The other was the Green Glue, which I went with. It's a really good product, not great, but it did do a solid job of reducing the walls shaking, and it was pretty easy to install.
