Attic insulation batt vs blown.

Disadvantages of batt insulation. The photo above shows an attic insulated with blown cellulose. That makes it fast to install but costlier than batt insulation. Blown insulation is accomplished by blowing out chunks of either fiberglass or cellulose from the hose of a blowing machine.

The thermal performance of fiberglass insulation is directly related to its ability to trap and maintain very small pockets of air. Blown in fiberglass creates a seamless blanket in your attic. Fiberglass insulation is available in blown in form and so is cellulose which is referred to as loose fill cellulose. Often times a combination of the two is ideal.

When insulating an attic space many homeowners ask us which is better blown in or batt insulation. Depending on the material of the insulation the installation method may vary slightly. Batts must be cut tightly and you can t have gaps. Compared to blown in insulation batts can reach a resistance rating r factor of over 3 1.
