Green glue how much

You should screw the drywalls together. Which would be better? Trademark Soundproofing Reply: 2 new layers. We were going to do insulation between joists, resilliant channel and then two layers of drywall. This is pretty standard n my area. How much of a different will it make if I apply 2 tubes of GG per sheet of drywall? Trademark Soundproofing Reply: Hi Dave. It will significantly improve your ceiling by about 9 STC points for airborne sound less for footfall sound.

If footfall sound is your main concern you should consider using Resilient Sound Clips , like the Whisper Clips. Trademark Soundproofing Reply: Hi Nick, You can use it however it would not perform that well vs if you use it between 2 layers of plywood and then add Kerdi Board.

Is that the correct order of things? The bedroom wall face the exterior street. Rather put the GG between 2 layers of drywall. Any suggestions on construction. Seems most folks are involved with drywall. I could have two inner layers of drywall separated by green glue. My main concern is the limited size of the box. Trademark Soundproofing Reply: Green glue is not really meant to be used in an exterior applications. Will the glue hold it up until dry or do I have to use screws as well?

If so how many screws and where best to position? Trademark Soundproofing Reply: Green Glue is not an adhesive you always have to use screws to keep the 2nd layer in place as per the building code in your area. Also on a floor you probably want to use plywood or OSB rather than drywall.

Trademark Soundproofing Reply: It works slightly. To maximize the Green Glue performance you want to use solid rigid membranes. Just wondering if the Green Glue products and masonite would be okay for this box. Code in my area as insulation of R On an exterior wall of otherwise unknown construction, would Green Glue work well if I double layered the interior portion only of the exterior wall? Basically meaning we did not remove any of the external siding and added layers there.

There are no windows along this wall. Trademark Soundproofing Reply: Yes it would work, however you may still be getting some of the sound through the ceiling especially if there is an attic above the room so you may want to consider treating that as well. Hi, I have a mirrored wall in my condo and plan to replace the mirrors on that wall. So, how does GG compare as an adhesive and in particular, is GG something I can use to fasten my new mirrors to newly installed drywall? Thanks, Dennis. Trademark Soundproofing Reply: Hi Dennis.

Green Glue is not an adhesive and should not be used that way. Would it be beneficial if I used green glue between the joists and the new plywood subfloor? So the joists would be covered in green glue and then the subfloor would be placed on top and screwed into the joists. Trademark Soundproofing Reply: The benefit would be minimal and not cost effective. You are much better off using the Joist Gasket Tape.

We can hear the man snoring in the unit above us. The condos were constructed to be one unit, then later they took out the stairs and made them separate. The ceiling has a heat vent in it, is "stippled" and painted. Would using Green Glue and drywall be a solution for us? Trademark Soundproofing Reply: If you have insulation in the ceiling than the added layer of drywall with GG will definitely help cut the sound down. The heat vent is an obvious short circuit in the sound control system as is the possibility that the sound could be flanking down the walls via pipes, ducts etc too.

Can I install a new layer of drywall over the existing layer with GG in between or do I have to rip out the existing drywall and texture? I want to make sure the existing texture won't affect the GG or new drywall. If not you can sand it down. Ive read about decoupling and adding insulation plus 2 layers of drywall with green glue in between. How much benefit would I receive from adding 2 layers of drywall with green glue in the middle?

I do not believe the sound is traveling down th plaster walls, but due to hard, heavy footsteps on glued down parquet floors over the concrete slab. Trademark Soundproofing Reply: If you will be decoupling first with the Clips and Channels than the Green Glue will help out tremendously. However if you are doing Green Glue alone than it won't be enough for footstep sounds. Hi, the drywall in my house has been painted, can I apply a second layer of drywall on top of the first one using green glue compound?

Will the compound stick to a painted surface? Can drywall tape or fire tape be applied over green glue sealant once it has dried in 48 hours? Trademark Soundproofing Reply: the answer to both questions is "Yes". I'm also going to put insulation in the joist bays. Will green glue work sandwiched between drywall and the wooden subfloor?

I read that it had to be sandwiched between building materials. Thank you, denise. Trademark Soundproofing Reply: The Green Glue can be used between drywall and plywood with no issues to performance. Can this glue be used sandwiched in between a layer of bricks and a drywall?

As I am trying to ensure that not too much space is taken from the room itself To achieve better outcome, how many walls in the room should be soundproofed with this technique?? Trademark Soundproofing Reply: That is not recommended. Rather use 2 layers of drywall on the brick with the green glue between the 2 layers. Ideally all six sides of a room should be soundproofed. Trademark Soundproofing Reply: Yes that can and is done all the time without any negative effects.

Trademark Soundproofing Reply: No it will not effect it. I am avoiding drywall because of the weight. Thank you for any info.

It needs either a 2nd layer of plywood or drywall. Adding another layer of OSB board can be costly as I'm trying to do soundproofing for about sq ft. Trademark Soundproofing Reply: Hi David.

That would be the preferred way to do it. Putting the Green Glue directly beneath the hardwood planks is not recommended. As the planks have grooves at the bottom. You can nail the hardwood down to the top layer of OSB. I have been advised not to add insulation to the interior wall as it will decrease ambient heat reaching that room. How do you weigh in on insulation vs.

Insulation on the other hand will make a very big difference. Hear walking all the time. Have plastered ceilings. Trademark Soundproofing Reply: Not enough for footstep noise to be worth your effort.

Which side would it be more beneficial to apply to keep noise out of the bedroom? Family room or bedroom side? Trademark Soundproofing Reply: Whichever side is the "source" of the noise that you are trying to control. Will the green glue be effective?

Try to be careful that it does not squeeze out at the joints. Would green glue work if I just put it on top of the plywood subfloor before laying my wood floors? Trademark Soundproofing Reply: Somewhat. Better if you put Green Glue another layer of plywood and then your hardwood.

Being that it will be a gym you will probably still hear the impact sound however it will be damped. Parallel to that stud wall, about 1. The paneling, which we like, has been removed and preserved. Then finish that wall by re-applying the wood paneling.

First question: should we attach the OSB or sheetrock adjacent to the studs. Second question: What is an adequate material to attach to the stud wall and GG-dampen with the mirror? The mirror will be supported by J-channel at the bottom and U-channel at the top, screwed to the wall.

The wall is How would you mate it, acoustically, to the mirror? Q4: How would you suggest sealing the gap around the mirror between the GG-mated surfaces? GG acoustic caulk? Trademark Soundproofing Reply: Hi Stan. I am not clear on your first question. What do you mean if you should attache it adjacent to the studs? As to the question about the mirror. The only way to achieve a proper damped wall would be to first apply 2 layers of drywall or OSB with the Green glue in between and then simply hang the mirror on that wall you can fasten it all the way back to the studs.

Trademark Soundproofing Reply: Yes. What is the best way to soundproof from noise from upstairs footsteps and other residential noise : 1. Trademark Soundproofing Reply: Hi Roman. Number 2 is the correct way you can screw the first layer down through the wooden planks into the joists too. After application of Green Glue, use standard drywall screws to fasten the drywall to the studs. 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. Do not let dry. Apply Green Glue within 15 minutes. Drywall sheets must be screwed together while the material is still wet.

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.

In terms of using 3 tubes of Green Glue per 4 x 8 sheet of drywall there is no testing that we have seen.

Those were the facts, and although they are limited here is our opinion on how to interpret the facts above. Yes, we will agree that Green Glue Noiseproofing Compound seems expensive however to cut the cost of Green Glue in half and use only 1 tube seems somewhat ill advised. The difference in labor between 1 and 2 tubes is simply spreading another tube or dispenser full of Green Glue onto the back of the drywall.

Each case of Green covers about square feet, or 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. You are just wasting your money! Wonderfully, Green Glue performs at an only slightly lower level if you use it at 1.

In fact, Green Glue can improve performance if used at even less than 1 tube per sheet. Jump to Navigation. Search form Search. How does constrained layer damping work? How is Green Glue applied?
