FIELD: fire safety.

SUBSTANCE: invention relates to multilayer heat-insulating materials and can be used in fire barriers, such as sliding screen curtain walls. Fire-resistant aggregate contains two layers of basalt fiber 1, wherein each of said layers is coated on one side with foil 2. Layers of basalt fiber 1 are glued to each other with non-foil sides over the entire thickness using a layer of adhesive composition 3.
