Insulating furnace room

I converted a spare room in my basement to a home studio and it's adjacent to the furnace room.

I was going to use Rockwool Safe & Sound to insulate the wall, and I have enough space to cram some insulation in the ceiling, and to wrap the duct work that is going into the studio room (see the pics). My plan was to cover the wall in the furnace room with foil insulation (reflectix or something?)and not drywall, mostly to save time, effort and cost.

My goal is to dampen some of the furnace noise coming into that room. I know the furnace room cannot be sealed so I thought I might just insulate all the interior walls with safe and sound, but I don't want to have to drywall that room.

Wondering if there anything else fire rated I can cover the insulation with, and if it's worth doing this. I don't expect it to be sound proof, I just want to absorb as much of the noise as I can as cheap as I can.

Jason, If your goal is to make the rooms as sound proof as possible, invest a little extra and do it properly. For the wall between the two rooms, the best way is to do a double stud system.Google sound proofing basements and you should see some examples. Also, drywall would muffle the sound better than the foil. The reason for the double studs is that single studs (wood) will carry sound and vibrations while double studs (with insulation between) acts as a much better sound barrier. And, yes, wrap the area around the heating ducts to muffle some sound. Again, don't skimp, you'll regret it. Cheers.

yeah, I've seen plenty of those soundproofing videos and articles. It's the cost and time tradeoff I'm trying to decide on. I built some acoustic panels using Rockwool for my studio and just having these in the room dampens the noise quite nicely so I thought if I just insulated the furnace room and covered the walls and ceiling, that would be good enough. I want to avoid drywalling but I get what you mean, probably better to bite the bullet and do it right the first time.

The vibration damping material is a high-density viscoelastic membrane with a protective coating of aluminum foil. The presence of an aluminum coating provides effective mechanical protection and resistance to temperature. The presence of an adhesive layer greatly facilitates installation.
