How does Imperial Beach's climate affect this service?
Coastal homes in Imperial Beach 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 blown-in is mostly attic top-ups in Coronado and Imperial Beach housing stock from 1970–1995.
Cellulose or fiberglass — which is better?
Cellulose has higher R per inch, better air-flow resistance, and is recycled paper treated for fire and pests. Fiberglass is non-organic, lighter, and easier in damp climates. In dry, mild San Diego we use cellulose more often unless the attic has past moisture issues.
What is dense-pack?
Dense-pack is cellulose installed at 3.5 lb/cu ft into closed wall cavities through small drilled holes. The high density resists settling, plugs air leaks, and adds R-13 to R-15 to a wall that previously had nothing. We patch and texture before paint.
