Abstract
A method of coating a substrate of insulation material with a barrier layer involves spreading a curable liquid on a surface of the insulation using a spreader blade having a composite cross section profile. The profile includes a leading surface that converges toward the substrate surface and a trailing surface that is parallel to the substrate surface. The coating method is useful for fabricating acoustical and thermal energy insulation boards of nonwoven webs of glass fibers and other conventional insulation material. Particular benefit is derived from the method in coating grooved insulation boards for lining curved air conveying ducts with an elastically deformable, flexible coating that covers the board surface between grooves and bridges the grooves while leaving the groove channels open.
