Room Isolation Basics
It is important to plan ahead if you want to keep sound from getting out of a new room setting, as the process to isolate the room must be done as construction begins - it's best to install Sound Isolation Products before any wall framing has begun. While we can work with rooms with existing framing in place, there is a noticeable drop in performance in these situations. Please contact us, or call #866-243-1001 toll free regarding your room and we will be happy to work with you to find the best sound isolation solution for your setting. Improvements in Room Acoustics, however, are done after the room is completed with our Fabric Walls, Acoustic Panels, Seating Riser Bass Traps and 4" Acoustic Front Walls. Room Acoustics, or Room Tuning, which makes the room sound great, is quite a different process than Sound Isolation, which keeps sound in.
The 3 most important Sound Isolation issues:
1. Floor Isolation - Acoustical Sound Absorbing Subflooring
The first issue to deal with to isolate a room from other room areas in a home is floor-borne vibration. As sub-woofers usually sit directly on the floor, in addition to main speakers also being located there, this is a major source of sound transmission to other rooms through the framing structure. Wood floors are good sound transmitters, but you would be surprised at how much sound concrete can transmit, as well. Carpeting helps some, but in order to both quiet the floor and also de-couple it from the wall framing, Sound Control for your Floors, such as our Floor Isolation Underlayment mats, is required. This helps stop energy from getting into the studs, which will stop sound transmission not only to adjacent rooms, but also to areas above the room. The entire floor, especially under the wall framing, needs underlayment treatment.

2. Framing Isolation - Resilient Sound Isolation Clips
The next
issue involves wooden studs and the sound they transmit through your room’s
framing. Both the floor below the studs, as well as the wallboard attached
to it transmit sound through the studs, which are then transmitting
vibration to other room areas. If you deaden the studs, you will stop sound
from not only being sent to adjacent room areas, but also from travelling up
through the ceiling. Using our Resilient Sound Isolation Clips is a very
effective method of controlling sound travelling through walls, as well as
up through ceilings to stop it from travelling to rooms above.
Resilient Sound Isolation Clips provide 2 unique approach's to sound privacy that will prevent sound from noisy neighbors transmitting through your walls or floor/ceiling assemblies.
Experience with the Clips has recorded remarkable improvements of up to an additional 20 STC points on walls. The Clips are designed to retrofit and improve existing walls and ceilings has shown to improve existing walls by as much as 8-10 db. by actual field tests.
-
Resilient Sound Isolation Clip shall be 48 inches maximum on center. (horizontal) - Fasten the Resilient Sound Isolation Clip to the substrate with a fastener approved for a minimum pull-out and sheer of 120 lbs.
- Ensure the internal metal ferrell is tight to the substrate. • Locate the first row of clips within 3 inches from the floor and within 6 inches from the ceiling.
- Snap in the drywall furring channel (hat track) into the clips (horizontal for walls).
- Place 1/4” (minimum) shim on floor to fully support the gypsum board.
- Install the gypsum board from the bottom up leaving a 1/4” min. gap around perimeter.
- ONLY remove the shims after ALL the gypsum board is completely screwed to ALL the drywall furring channels. Make sure every screw (floor to ceiling and wall to wall) is installed as required by the assembly design, in every layer of gypsum board before removing the shims at the floor. The shims are critical to ensure best results.
- Caulk around the entire perimeter of the gypsum board. Use fire and smoke rated acoustical sealant.
3. Wallboard Isolation - Green Glue
One last important issue to deal with is sound vibration picked up by the room’s wallboard. Wallboard acts like a microphone, picking up sound vibrations in one room, then transmitting through the attached studs in the framing. The attached wallboard on the other side of the room then “picks up” the sound vibration transmitted through the studs and acts as a loudspeaker, sending the sound vibration into adjacent rooms. Using double drywall with Green Glue applied in between the wallboard on walls and ceilings is highly effective in stopping sound transmission.
Green Glue is a liquid, waterborne, viscoelastic damping compound which represents the highest performance product of it's type. We are aware of no product available to the construction market which can deliver damping levels even 30% as high as those offered by Green Glue. It is also significantly lower in applied cost than competitive products, getting a better cost/performance ratio in the damping of normal construction materials such as drywall,
wood products, etc. Finally, it is remarkably tolerant to real-world application conditions and carries almost none of the burden of precision required by many damping systems.
- Non toxic
- No mixing required
- Simple, familiar, "caulk gun" application
- Considerably reduced application cost
- Light material squeezes from tubes easily low worker fatigue
- Improved sound isolation
- Constructions with outstanding low frequency isolation are possible
- Thoroughly lab tested
- Eliminates short circuit risk in resilient channel walls
- Allows construction of the highest performance walls possible (in combination with double stud walls)
- Reduction in structure-borne sound
- Low cost product = great $$$/performance
Installation tip: Standard performance requires (2) 29 oz tubes of Green Glue per 4' X 8' sheet or drywall. For enhanced performance use (3) 29 oz tubes per 4' X 8' sheet of drywall. Simply apply product between 2 layers of drywall and mount drywall to existing wall. Apply sealant around the perimeter will also enhance wall assembly.
