Insulative composites as well as articles formed therefrom are described herein. The insulative composites include a fibrillated polymer matrix, insulative particles, and additional particulate components such as at least one of reinforcement fibers, expandable microspheres, and opacifiers. The insulative particles and additional particulate components are durably enmeshed within the fibrillated polymer matrix. The insulative composites act as a heat propagation barrier when exposed to temperatures sufficient to partially or completely volatilize the fibrillated polymeric matrix within the insulative composite. The insulative composite is suitable for use in applications and/or in articles that have at least one thermally sensitive component that is capable (generally upon failure of that component) of releasing energy that is sufficient to result in a temperature that partially or completely volatilizes the fibrillated polymer matrix within the insulative composite yet still provides a sufficient insulative effect to protect one or more adjacent thermally sensitive components from damage.
