An earlier post dealt with my new _very noisy_ Generac
14 kW standby generator. I've searched online for some sort of exterior acoustic panel / material to no avail. What I've found is either interior use or giant things for railroad or freeway use. Any suggestions are welcome. Even a product that I could re-purpose .. I'd estimate that 2 4 x 8 sheets of something would be plenty - not enclosing the unit but sound-insulating the brick wall behind and concrete pad underneath ; and skirting the 1 ft. stand that it sits on .. perhaps some on the ends so as not to restrict air flow ..
