Inland heat plus SDG&E fire-zone designation make both energy upgrade ROI and ember-resistant ventilation upgrades essential on every replacement.. East County soundproofing demand spans home offices, gyms with weight drops, and music spaces.
What STC rating should I aim for?
Code minimum for shared walls is STC 50. STC 55 starts to feel quiet between rooms; STC 60 is what you want for a recording space. The pro designs to a target STC, not just to a product. Mineral wool gets you maybe 4 to 6 points; the rest is mass, decoupling, and sealing.
Will mineral wool alone soundproof my office?
It helps but it isn't the whole answer. Most noise comes through gaps, doors, and flanking paths. Plan on sealing penetrations, gasketing the door, and possibly adding a second layer of drywall with green glue. The pro designs the whole assembly.
