Full-scope insulation including attic R-49, crawl space freeze protection, and ember-resistant ventilation is standard on every project..

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.
