How does Del Mar's climate affect this service?
Coastal homes in Del Mar run cooler than inland but still benefit from a top-up to R-38 and aggressive air-sealing. Marine humidity migrates through any open chase, so we hunt those leaks first before insulation goes in.. Coastal soundproofing requests usually come from home offices in dense Coronado and Imperial Beach housing.
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. We design 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. We design the whole assembly.
