Laminate barrier with silicone foam layer defining voids containing endothermic material

An article comprising a multilayer laminate that comprises:

• (a) a first surface layer with opposing primary surfaces, the first surface layer comprising a crosslinked polysiloxane matrix with flame retardant additive dispersed therein at a concentration in a range of 5-95 weight-percent based on first surface layer weight;
• (b) a central layer with opposing primary surfaces with one primary surface adhered to a primary surface of the first surface layer and wherein the central layer is a silicone foam sheet that is a silicone foam matrix with fire retardant fillers dispersed therein at a concentration in a range of 5 to 80 wt % based on silicone foam sheet weight;
• (c) a second surface layer with opposing primary surface with one primary surface adhered to a primary surface of the central layer opposite the primary surface adhered to the first surface layer, the second surface layer having a composition a described for the first surface layer though the first and second surface layers do not have to have the same composition;
• wherein the central layer defines one or more than one void such that the total volume of voids defined in the central layer is in a range of 5 to 95 volume-percent of volume defined by the central layer and wherein the article comprises endothermic agents that occupy the voids in the central layer.
