A Cooler House installs blown fiberglass and cellulose attic insulation. Honestly both products are good insulators. • Fiberglass • Fiberglass is very light and tends not settle over time like cellulose might. • Fiberglass has a R value or 3 per inch • Cellulose • Cellulose is more dense than fiberglass and therefore is a better barrier for air movement through holes in walls and ceilings. • Cellulose has a R value of 3.
