Green Glue

[Swa]

Does anyone know where one can buy this locally? I found the local official supplier but they don't seem to have a store. Another claims to be the exclusive importer but seems a bit dodge.

For what application? In some cases there are alternatives to the expensive green goop.

I'm looking for the sealant. The actual glue (well I think it is a glue) is reported in independent testing to be among the best. Amazon has them at around R1400 for 12 but I don't think I will use more than 2 so would prefer to buy locally as needed.

Also Aerolite is apparently a good sound insulator as well. Are there any products specific for noise reduction and what would their thermal properties be? I'm not looking for total blocking at this stage as some noise will still be coming through the window itself so if too expensive versus Aerolite or poor thermal performance will rather go with the pink stuff.

I see they are now owned by Saint Gobain whose products have a local retail and distribution presence.

You need to quantify what noise you want to attenuate from passing between rooms. Is this a home recording studio/home theatre, are you looking to reduce footfall noise, what frequencies...etc You can use online guides for STC values to quantify likely outcomes on one important assumption: everything is sealed.

Air gaps are the most effective leaks in room acoustics. You can seal with conventional building materials, green glue and similar materials come in when you need a lossy visco-elastic mastic that absorbs vibration in a constrained layer damping panel (meaning vibration is converted into heat).

What room boundaries are involved (floor, interior/exterior wall, roof)

That's the problem. Air grates that have to be plastered, windows that don't close properly, gaps around frames. I did an experiment pulling one as tightly as I could and the reduction in noise was remarkable. Want to try the non-expensive routes to get things sealed up first. Certainly some noise is coming in from the ceiling as well and may look to the pink stuff and styrofoam tiles for that but don't want to spend money blocking more noise than what's coming in through the glass anyway.

Problem: several dozen small feet have taken up residence and is driving us nuts.

Rats in the roof?

Rats in the roof?

That would be easy to solve. 2-3 foot long ones that scream and shout all day then go up and down paving on plastic scooters, not so easy. If I didn't know any better I would swear it was a rollercoaster they have there.
