wood fiber rigid panels
Rigid sheets or blocks made from wood fibers and used as a thermal-insulation layer.
Wood fiber rigid panels are hard sheets or blocks of thermal insulation made from wood fibers. These generally have a low insulation rating, and must be protected from fire and moisture.
The wood fibers form a firm panel or block. Loose fiber fill and ordinary solid timber boards are different material forms.
The panel serves as insulation rather than merely as a visible wood finish. Its exposure to fire and moisture remains relevant even when it is concealed by another wall layer.
