Product Description

TherMix, a ready-mix, Vermiculite-based masonry material. TherMix cures into a lightweight, semi-hard mass that forms 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. This eliminates airflow and moisture build-up between the liner and chimney.

TherMix maintains higher temperatures on liners when flue gas temperatures are low: Maintaining flue gas temperatures above dew point, (~128°F), is essential to avoid condensation. The insulating mass of TherMix retains the maximum available heat close to the liner: the flue stays warm for a longer period of time after the appliance shuts down. With oil and gas appliances, keeping the flue warmer between firing cycles greatly reduces the possibility of momentary flue gas spillage which occur at the start of the next cycle. With wood burning applications, warmer flues help eliminate back puffing and other draft related problems. 

A minimum order of 5 bagged Thermix Insulation is required. Thermix Insulation bags are shipped on a pallet via freight line.

    Calculating the amount of TherMix Insulation needed:

    (W x D x H) - (L x H) = Total Volume

    Divide this number by 1728 to convert from cubic inches back to cubic feet. Divide the final amount by 3.25 to see how many bags of TherMix are needed.
