    • TherMix Chimney Insulation
    • 2.4 - 3 cubic feet bag at approximately 44 lb. per bag
    • UL Listed 1777 Zero Clearance insulation for HomeSaver and Ventinox
    Thermix insulation is a ready-mix compound that you mix with water and pour in the space between the liner and the masonry chimney. This creates a UL 1777 listed zero clearance insulation that is recommended for use with Ventinox VG, VFT and HiFlex liners as well as other HomeSaver relining pipe. A pour-in insulation can be used when space is too tight to install a blanket-style insulation. One bag holds 2.4-3 cubic feet of mix and weighs approximately 44 lbs.

    Does this TherMix come in a pre-mixed caulk?
    By Will M. on May 22, 2017

    Answer:
    As the TherMix arrives in a bag that is mixed with water and poured around chimney liner as insulation when relining a chimney and serves no other purpose, there would be no reason for a pre-mixed tube of caulk to be offered.

    By Jack from St. Clair Shores Michigan on February 25, 2012
    We have a Natural gas log fireplace. The ceramic tiles have been removed from the surround, and now there is cold air coming in from around the unit. I removed some drywall to inspect the area around the unit , there isn't any. What type of insulation would be the best to solve this problem?
    By Collin C. - NFI Master Hearth Professional on February 27, 2012

    Answer:
    Rather than this type of pour in insulation, it would be recommended to seal the space with unfaced fiberglass insulation. It is necessary to keep the insulation from actually touching the sides and back of the unit.

    You can staple the insulation to the surrounding framing in order to keep it in place. It may also be necessary to gain access to the outside wall to add insulation, as this is most likely the source of the cold air.

    My chimney is 7 x 13 " and I am putting in a 6 inch liner and the chimney is 20 feet long. How many bags will be needed?
    By Will M. on October 20, 2016

    Answer:
    You will need 4 bags of Thermix if you are using 6" round flexible chimney liner.
