Im new here and am just starting my build. i will be building a frame for my subfloor and was looking at sound deadening/insulation for the floor followed by 12mm Marine plywood… I found this stuff which seems very reasonable priced however i don’t believe it does both insulation and sound deadening. As most videoes i see on youtube etc people use two different materials, 1 for insulation and 1 for sound deadening.
Any feedback on this is appreciated.
FYI i am in Victoria australia and dont require super good insulation due to the climate i will be using the camper in
