Flame-resistant insulation may be prepared by coating a glass fiber substrat e, such as a fiberglass board, with an aqueous dispersion of vermiculite and expandable graphite. The insulation may also be pre-coated with a vermiculit e dispersion prior to coating with a vermiculite/expandable graphite coating, and the vermiculite/expandable graphite coating may be covered with an FSK facing, or with a gypsum or portland cement layer. The resulting coated insulation board has superior flame resistance, and may be used as a compone nt of a building or in vehicles. |
