I'm about to hang one of the LED big screen TVs on my wall. To tidy

inside wall. The master bath is on the other side of the wall. Why
is an inside wall insulated?

Noise reduction.

My previous home had insulation in every interior wall and was MUCH
quieter than my current home with no interior wall insulation.


If you have any pipes in that wall, be thankful the builder put the
insulation there otherwise everytime someone flushed or ran the water you'd
hear it loudly in the adjoining room.
