wood fiber batts
Flexible sheets or pads of wood fibers used as thermal insulation in the form of batts.
Wood fiber batts are sheets or pads of fibers made from wood. They need protection from moisture and fire, and handling or cutting can release wood-fiber dust.
The wood fibers form flexible insulating units rather than rigid boards. Their batt form allows them to occupy spaces between framing elements.
Batt insulation describes the physical form, while wood fiber identifies the substance. The material remains distinct from wood used as a structural beam or exterior finish.
