Abstract
Panels are disclosed which are suitable for joiner, non-structural bulkheads. The panels are a laminate having a central portion of gypsum or a magnesium oxy-chloride cement which may or may not be glass fiber reinforced and externally exposed fire-resistant skins directly bonded to opposite sides of the central or core material. These skins are formed of a solid phenol-formaldehyde glass resin composite such as for example a prepreg formed from a woven glass roving of a high strength, high melting point glass and a cured phenol-aldehyde resin.
