Fiberglass questions can leave you, well...scratching your head. Are fiberglass blankets superior in heat retention to blown in insulation? Is the R value of your fiberglass insulation affected by other factors in the attic? Fiberglass answers here will help save the head-scratching for another decision!
Basement insulation may help keep your first floor warmer. Is insulation added to basement ceilings between the floor joists worthwhile? Insulation slows heat transfer, but choosing to insulate your basement ceiling is not the most efficient. Basement wall insulation may be the answer.
Cellulose vs. fiberglass insulation -- which is the best choice? Fiberglass has caused some health concerns. Cellulose insulation requires due care, as cellulose insulation and electrical wiring can produce intense heat, which can cause fire. Both fiberglass insulation and cellulose will settle when blown in, and R value is affected.
