I have used Green Glue for my studio and it has worked great, specifically for low frequencies. The application of it is the main issue, many users do not know how to use it correctly and then have poor experiences. You'd need 3 tubes per 4 x 8 drywall sheet, it must be sandwiched between two drywall sheets and you have to ensure that it is applied evenly. Just as a rubber wheel heats up on flexing and contraction, the green glue does the same, hence the drywall facing the sound source must have some give for it to vibrate so it can then transfer those low frequency vibration to the green glue between the two sheets that will turn those mechanical energy waves to thermal energy. You have to remember this is a finishing product and must be used in conjunction with other sound proofing methods.
Hi, I am doing knauf silenboard ceilings and wondering if i should add tecsound in between each plaster board + at the top of concrete before hangers?, if so, any idea where to buy in europe? What model tecsound do you recommend?
Hi @agreatd, our recommended ceiling system is the ReductoClip System: www.soundproofingstore.co.uk/ceilings ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4aPYW2HbF2E.html We also now have an excellent alternative to Tecsound SY100 called FlexiSound 5: soundproofingstore.uk/product/flexisound-self-adhesive/
hey, I am going to be moving into a newly built social housing. I am worried about noisy noisy neighbours, the wall construction is, breeze, cavity breeze. Can I get away with just doing the adjoining wall and not the ceiling, in the living room? which would be the most cost effective way to go about doing this, aiming just for a reduction not a overall removement of sound which i know would cost too much.
Hi Silly Wabbit - I would wait to you are in there before deciding whether you need to soundproof. A double skin construction like that will probably already be doing a pretty good job. You should only need to further improve it if the neighbours are being very loud. Then contact us direct and we can talk through some options that will be right for the type and level of sound coming through.
Hi @tedebayer1, thank you for taking the time to share your experience of using Green Glue. This video on FexiSound (an alternative to Green Glue) might be of interest: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fffHFAVgdGI.html Similarly to Green Glue, FlexiSound is also viscoelastic. and when placed between two sheets of acoustic plasterboard gives the wall the ability to dampen sound energy and vibration. However, unlike the acoustic glue the FlexiSound also creates a barrier of mass. This is important as it's mass that predominantly blocks airborne sound. FlexiSound adds an extra 10kg per m2 and is only 5mm thick. Compare this to the Green Glue which is adding absolutely no mass whatsoever. Also, because the acoustic glue doesn't uniformly cover the entire wall, it doesn't create any kind of air tight sealed barrier to help block sound.
Hi @74betty - If noise is coming in due to gaps around the window, I wouldn't suggest green glue, you want to use an acoustic sealant like this soundproofingstore.uk/product/soundproof-acoustic-sealant-900ml-tube/ However, there is a very good chance that noise is coming thorugh the window just because windows are a weak point naturally. They have a tiny fraction of the mass of the rest of the wall. You may need to consider having secondary glazing installed.
Hi Robert, i'm afriad we are not fully aware of all the materials available to the US market with us being UK based. The closest type of material would be Mass Loaded Vinyl, althoguh it's not exactly the same and doesn't have all the same properties.
Hi The Nub - As we say in the video, we don't really recommend this approach at all, so switching to another type of sealant / adhesive to do the same thing would also not be recommended.
@@thenub5606 Hi Yes we would always use acoustic sealant for any gaps (particularly around the perimeter) as soundproofing is like waterproofing and is only as good as the weakest point.
