1. A construction board comprising:
- (i) a foam core having first and second planar surfaces, where the foam core includes a polyisocyanurate cellular structure having an index of at least 175 and being formed by contacting an A-side stream of reactants including an isocyanate compound and a B-side stream of reactants including an isocyanate-reactive compound;
(ii) an interfacial region including a filler dispersed within a matrix, said interfacial region being disposed on said first planar surface of said foam core; and
(iii) a non-woven inorganic mat disposed on said interfacial region opposite said foam such that said core and said mat sandwich said interfacial region.

14. A construction board comprising:
-
(i) a foam layer, said foam layer including polyisocyanurate and having first and second planar surfaces; (ii) a coating layer having first and second planar surfaces, where said first planar surface of said coating is mated to said first planar surface of said foam layer, said coating layer including an inorganic filler dispersed within a polymeric matrix; and (iii) a non-woven mat having first and second planar surfaces, where said first planar surface of said non-woven mat is mated to said second planar surface of said coating layer. - View Dependent Claims (15)
