Abstract
The present invention teaches a textile structure and method of making thereof which is useful for fire blocking a structure and insulating it from sound and heat. The textile structure includes at least one composite having three layers which are placed upon one another to form top, middle and bottom layers. The middle layer is a densified matt or batting having at least 10% by weight of carbonaceous fibers. The top and bottom layers are less densified matts or battings which have at least 10% by weight of carbonaceous fibers. Multiple composites may be secured together for increased protection against fire, sound and heat.
