Attic Insulation Benefits

Many homeowners complain that they run their air conditioner all day but the house never gets as cool as they would like. This is the sign of a poorly insulated attic. Insulated attics keep in the cool air in the summer and warm air in the winter. An insulated attic provides a barrier as well so during winter the cold air stays in the attic and doesn’t leak into the house. This applies to summer as well where the hot air stays in the attic keeping the house cool. Additional benefits of insulating an attic with blown cellulose is the cellulose provides moisture resistance to decrease chance of mold and fire resistance.
