Hello again,

does anybody have any information if inserting a layer of asphalt sheet (Sheet specifications - material used for isolating roof) between gypsium boards is of any benefit for sound isolation or is it just not worth the expense?

Some say it is not worth it "As for the layer of asphalt-sheets - not worth the trouble or expense. If you want great isolation, get the Green Glue."
Need some advice on soundproofing and acoustic treatment of my tiny studio

other use it regulary when building new constructions...
"If you use a double gypsum board structure you reach already 48dB of STC. Add a layer of 4mm of asphalt in rolls in sandwhich between each double layer of Gypsum and you get very close to 56dB (lab measurement, not real life measurement)."
Who is using Green Glue in their studio build?

Thanks,
