A composite building insulation panel includes a rigid foam core having a planar surface, a facing bonded to the planar surface, and at least one layer of mesh embedded within the foam core. The facing includes an outer skin layer and a reinforcing layer between the planar surface and the outer skin layer. The embedded mesh may be coated with an intumescent material.

A method of manufacturing a decorative surface laminate incorporates a sheet of cellulose-based inclusion paper. The inclusion paper includes a print surface having a porosity greater than 1.25% and a decorative ink finish digitally printed directly onto the print surface of the inclusion paper. Multiple sheets of backing paper are stacked with the inclusion paper, such that the backing paper resides adjacent the inclusion paper on a side opposite the print surface. The inclusion paper and backing paper are impregnated with a thermosetting resin. Using heat and pressure, the impregnated sheets of inclusion paper and backing paper are combined to form a flexible high-density laminate panel.
