Blown in Attic Insulation
Blown in insulation, as opposed to batt insulation which uses fiberglass blankets, creates a seamless blanket of insulation in your attic. You could spend hours kneeling to achieve the same result with fiberglass batts in your attic. Once installed and expanded to the uniform thickness, batts offer a known, consistent R-value. However, blown-in insulation thickness can vary in an attic space which leads to non-uniform R-values. Cellulose is a common and advantageous type of blown in insulation. One of the main advantages is its fire retardant characteristics.
