How does Alpine's climate affect this service?
Alpine attics hit 150–160°F in summer and most original tract-home insulation has settled to R-15 or worse. R-49 blown-in cellulose plus air-sealing is the standard scope and one of the highest-return home upgrades in the county.. East County blown-in attics are where this service earns its keep.
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.
