Fireside's Poured Insulation is a mixed, vermiculite masonry material used for chimney flue insulation.


How many vermiculite bags of Fireflex chimney insulation mix are needed for your installation?


Manual Example:


A chimney that is 13" Long X 13" Wide and is 15' Tall with a 6" Liner installed needs 8 bags of Fireflex Mix. (see calculations below for an explanation)

STEP 1:
Measure the Length & Width of the interior of the chimney space. Multiply them together to find the GROSS area in sq-in.
Example: 13"L x 13"W = 169 GROSS sq-in


STEP 2:
Look at the chart below to find the area of the liner to be installed (Choose either the Round or Oval section depending on the liner shape). In the chart a 6" Round Liner = 28.26 sq-in. Subtract the Liner area from the GROSS area in Step-1.
Example: 169 - 8.26 = 140.74 sq-in NET sq-in area.


STEP 3:
Multiply the NET sq-in area by the Height (in inches) of the chimney to find the Cubic-Inch volume.
Example: 140.74 x 180"H = 25333.2 Cubic-Inches


STEP 4:
Convert Cubic-Inches to Cubic-Feet by dividing the Cubic-Inches from Step-3 by 1728 ( 1728 = 12L x 12W x 12D )
Example: 25333.2 / 1728 = 14.66 Cubic-Feet


STEP 5:
Each Fireflex Mix bag is 2 Cubic-Feet. Divide the Cubic-Feet from Step-4 by 2
Example: 14.66 / 2 = 7.33 = 8 Bags required
