What is the best type of attic insulation material?
Each type of insulation has distinct properties; the best choice depends on your needs and preferences. Cellulose insulation: Cellulose is essentially newspaper and cardboard that has been shredded. It is organic and porous, which means it does a great job of trapping air. Its insulation properties seem to last longer than other products because it doesn’t settle as quickly. It’s also treated with boric acid, which provides a level of fire retardation and helps repel insects and bugs. Batt or blown insulation: Loose insulation is good as long as it is applied evenly throughout your attic. Blown insulation reaches cracks and crevices that batt insulation may miss.
