How does Potrero's climate affect this service?
Potrero is rural border community east of Tecate at 2,500 ft, large parcels, equestrian properties, wind energy farms on ridges, and self-sufficient lifestyle. Off-grid solar adoption common, propane heating dominant, full-property insulation scope standard.. Backcountry blown-in often goes deeper than code minimum because winter heat loss is a bigger concern than summer cooling.
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.
