About TherMix

TherMix is a ready-mix, vermiculite-based masonry material. It cures into a lightweight, semi-hard mass, forming a thermal insulation barrier to keep flue gases warm and exterior chimney surface temperatures within safe limits. When poured into the masonry chimney, TherMix fills voids and cracks and eliminates airflow and moisture build-up between the liner and chimney.
