What is the difference between blanket and batted insulation?

The correct answer pertains to the type and form of insulation provided in each variant. Blanket insulation typically refers to insulation that comes in large rolls or sheets, such as fiberglass batts or rolls, while batted insulation usually indicates a pre-cut and fitted type of insulation that is designed to fit into standard spaces such as wall cavities.

Blanket insulation is more flexible and can be cut to size, making it ideal for covering larger areas without seams. In contrast, batted insulation is often made in specific dimensions to fit between wall studs or floor joists without needing to cut it. This distinction emphasizes their respective applications and ease of installation.

The other choices may seem relevant, but they do not capture the fundamental difference between these types of insulation. For instance, thickness might vary within both blanket and batted forms, and backing or foil may not be a constant trait among all types of insulation material. Therefore, focusing on their dimensions and forms illustrates why blanket and batted insulation are viewed differently in construction contexts.
