Fesco® Board HD

Fesco® Board HD Roof Insulation is a 1"(25 mm) thick, high density homogeneous rigid insulation board, composed of expanded perilite, blended with selected binders and cellulosic fibers. The expanded perlite contains air cells which provide superior insulating efficiency. The top surface is sealed with a special TopLoc® coating to prevent excessive absorption of asphalt during the installation process.
