Fire resistant panel member and method for producing a fire resistant panel member

A fire and smoke resistant panel member, comprising:

• a first layer and a second layer covering at least a portion of a surface of the first layer, the first and second layers each comprising a pigmented polyester resin and a first organic peroxide;
• a substantially rigid core member covering at least a portion of a surface of the second layer;
• and
• a third layer covering at least a portion of a surface of the second layer and a fourth layer covering at least a portion of a surface of the core member, the third and fourth layers each comprising a polyester resin, a flame retardant, a second organic peroxide, and a fiber material;
• and
• wherein the panel member is configured to have a maximum flame spread index of less than or equal to 25 and a smoke development index of less than or equal to 450.

A fire and smoke resistant panel member, comprising:

• a first layer;
• a second layer covering at least a portion of a surface of the first layer, the first and second layers each comprising a polyester resin and a first organic peroxide, wherein the polyester resin of the first layer and/or the second layer is pigmented;
• a third layer covering at least a portion of a surface of the second layer;
• a substantially rigid core member covering at least a portion of a surface of the third layer;
• and
• a fourth layer covering at least a portion of a surface of the core member, the third and fourth layers each comprising a polyester resin, a flame retardant, a second organic peroxide, and a fiber material;
• wherein the panel member is configured to have an ASTM E84 Class I fire and smoke rating.
