How does Rainbow's climate affect this service?

Rainbow is far-north county rural property at the Riverside County line, ranch and equestrian parcels with attic insulation upgrade as the highest-ROI energy improvement available, plus pipe freeze-protection driven by cooler winter mornings than most of San Diego County.. Inland blown-in is the most-requested insulation service in Escondido and San Marcos.

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 the pro uses 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. The pro patches and texture before paint.
