I’m setting up shop in a 12’ by 18’ space created by walling off a section of my laundry room, and I’m looking at sheeting the 18’ wall which is shared by the family room. The shop wall is currently unsheeted, i.e., I’m looking directly at the wall studs and the back of the family room paneling (it’s not drywalled). For reference, this is a split-entry house with lower-level family room and laundry room/shop, and the shop has two interior walls (adjacent to the family room and the laundry room) and two exterior concrete walls. I have a few questions:
(1) For the 18’ wall, I’m leaning towards using fiberglass insulation behind 1/2” plywood behind 5/8” drywall. My goals are to create a decent sound barrier and to provide a strong surface for hanging items on the wall without always having to find a stud or bank on anchors/toggle bolts. Does this approach seem reasonably cost-beneficial?
(2) Currently, the 12’ dividing wall (sectioning off the laundry room) is unsheeted on the laundry room side, and sheeted with 1/2” drywall on the shop side. If I use fiberglass insulation and 5/8” drywall when I sheet the laundry room side, will that be sufficient for soundproofing? Or should I add another layer or do something else with the shop-side wall?
(3) What is the best way to soundproof the shop-to-laundry room door? The dividing wall is roughed in and there’s a small but visible gap between the door frame and the studs/drywall, so I assume I’ll need to fill that in and put some sort of sheeting or trim over it. I also assume I’ll need to do something along the floor line, since the door is about 1/4” off the floor. And I may even need to replace/modify the door, since I think it’s a frame/panel job with top and bottom panels.
(4) The ceiling is also unsheeted, and I’m looking up at exposed electrical/plumbing/HVAC lines. Obviously, this will be a major source of sound transmission that will need to be fixed eventually. I can put up (or contract out) insulation and drywall on the ceiling, but there’s a large HVAC duct that drops below the joist line. What’s the most cost-effective way to soundproof that duct? Should I rough in short studs around the duct and just insulate/drywall along it, or is there a better solution?
Although I’ve been woodworking for a little while now this is my first foray into home improvement, so any advice is appreciated (and I apologize for any imprecise/unclear descriptions). Also, for all of the above cost is something of a factor, so I’m looking for an optimal return on investment at a decent price (rather than paying top dollar for the best soundproofing imaginable). Thanks!
