Everguard Chimney Insulation Mix is a ready mix, vermiculite based insulation material. This pour-down insulator is an alternative insulating method to using the blanket wrap. Ideal for tight relining jobs or when an uninsulated liner had already been installed.
Not only is it easy to work with, but also helps fill dangerous voids in masonry and strengthen chimney walls. It cures into a lightweight, semi hard mass. Moreover, this adds support to the chimney liner and forms a thermal barrier to keep flue gases warm.
This product adds performance to your chimney liner and is very durable. The mix eliminates moisture buildup between the liner and the chimney structure.
Installation for Chimney Insulation Mix
Simply prepare by gradually adding 4-7 gallons of water. The insulation is properly mixed if it holds together when squeezed in your hand. Additionally, no water should come out when squeezed. Pour the mix around the chimney liner, while shaking the liner slightly to let the mixture settle. Next, let it solidify. Cure time is 24-48 hours.
One bag weighs 45 lbs and covers 2.5 cubic feet. See insulation mix instructions.
Note: A chimney balloon is the best solution to prevent insulation mix from leaking into your fireplace or down into your cleanout door at the base of your chimney. For example, inflating a chimney balloon just below the thimble will prevent the insulation mix from filling up the flue cavity below the thimble. Remove balloon before lighting a fire.
Additional Details:
- Poured into the chimney after the stainless steel liner is installed.
- Distribute evenly around the liner and vibrate the liner by firmly tapping it while pouring insulation around it.
- The insulating material must be 6" below the crown to allow for vertical thermal expansion.
- Be sure no insulation mix has fallen into the liner.
- Heating appliance or fireplace permitted for use after installation. Keep flue gas temperatures below 700 degrees F for a period of three weeks to allow for a gradual drying process of the insulating material.
- A 1" layer of Everguard Insulation Mix between the liner and 4" nominal masonry provides a zero clearance listing from the chimney masonry exterior to combustibles.
- Removeable
