I'd like to install insulation in the walls of my home theater room (currently there is none). Does anyone have recommendations on products that are easy to install with minimal damage/repair necessary? I have heard there are companies that will spray in foam through small holes put in the drywall. Thank you!

What is your goal for the insulation? If it's for taming resonance and you don't want to remove the drywall, you could also use blown in insulation through relatively small holes. It's more expensive than pink fluffy, but less expensive than new walls...so. If this is for sound, I wouldn't use foam.

Thank you for the recommendation! Yes, this is for sound dampening/bleed through to other rooms.

foam is not the best choice if it cures rigid it will defeat your soundproofing efforts, blown in loose fill would be better. keep in mind insulation by itself is not a sound proofing tactic
