<p>Glass fiber septa (30) and insulation product (36) containing septa (30) between two glass wool layers (24) are treated, and thus rendered fire-resistant, by placing a phosphate-containing compound onto or in close proximity to the glass fibers. The phosphate-containing compound relases phosphoric acid when thermally degraded to form a protective silicate phosphate ceramic coating on the surface of the fibers. Exemplary phosphate-containing compounds are mono and diammonium phosphates, dicalcium phosphate, monocalcium phosphate, phosphoric acid, aluminum phosphate, and mixtures thereof.</p> |
