Structodek Roof Insulation

Knight-Celotex Structodek high density Fiberboard Roof Insulation is a uniform density, non-asphaltic board with good insulating properties. Composed of interlocking fibers of cellulosic material treated for additional strength and moisture resistance, it is a general-purpose roof insulation that is especially well suited for installations requiring unusual strength and rigidity. Structodek high density coated 1-side roof insulation is further treated on the top surface to reduce asphalt bitumen absorption. Structodek high density coated 6-side roof insulation takes that further treatment to all exposed surfaces for maximum protection.
