We use both blown in and batt insulation depending on the situation at hand.

Blown in blanket insulation vs batts.

Batt insulation is precut in rectangular pieces. Compared to blown in insulation batts can reach a resistance rating r factor of over 3 1. Blown in varieties however typically reach a peak of around a 2 8 r factor. Disadvantages of batt insulation.

Bibs meanwhile can be as high as r 49. The answer is it depends. The thermal performance or resistance to heat flow r factor is not the same when comparing fiberglass batts to blown in fiberglass. One variation of fiberglass loose fill insulation is the blow in blanket system bibs.

Batts offer a slight advantage. When insulating an attic space many homeowners ask us which is better blown in or batt insulation. The higher the number the better.
