A lightweight multilayer flame barrier includes alternating layers of a metal foil and an insulation layer to form a barrier layer. The metal foils may be configured on both the barrier surface and the interior surface. A barrier layer may be attached or coupled to a support layer. The lightweight multilayer flame barrier may be configured as a portable shelter that can be carried by fire service people and therefore may be lightweight and thin to enable compact storage and transport. The lightweight multilayer flame barrier may provide high convective exposure time in a thin lightweight composite.
