Blown-In in Boulevard, CA.
Blown-In for Boulevard homes, done by licensed San Diego County technicians. Blown-in is the workhorse for retrofits. Cellulose or fiberglass loose-fill goes into attics fast and cheap.
Why is blown-in different in Backcountry San Diego?
Backcountry blown-in often goes deeper than code minimum because winter heat loss is a bigger concern than summer cooling. R-60 cellulose attics are common in Julian and Pine Valley.
What's included in blown-in in Boulevard?
- Cellulose or fiberglass loose-fill for attics
- Dense-pack cellulose for closed wall cavities (drill-and-fill)
- Truck-mounted blowers for proper density and reach

- Baffle installation at eaves to protect soffit vents

How does Boulevard's climate affect this service?
Boulevard sees real winters along with hot summers. We push to R-49 minimum in attics, pay close attention to crawl space rim joists for freeze protection, and use mineral wool on exterior assemblies that see freeze-thaw cycles.. 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.
