To calculate the number of kits needed to
do your job follow these guidelines.
Example: 16” (1.25 ft) wide and 9 ft tall between the wall
studs. Total area between the wall studs = 11.25 square feet.
Multiply the square footage of the wall cavity times the depth
of the cavity in inches. In our example the wall is constructed
with 2 x 4’s
and the cavity depth is 3-1/2 inches. Multiply 11.25 S.F. x 3.5
as the cavity depth in inches and your board feet per cavity will
equal 39.38 board feet. If you calculate the number of wall cavities
you want to fill x the board feet per cavity you can determine
the number of kits you will need to finish your job. Our largest
kit the 2-43 has 600 board feet capacity. This would enable you
to fill approximately 15 of the wall cavities described in the
example above. Please see this video for an illustration of how
Handi-Flow® Pour in Place will rise and fill an enclosed space such
as a wall cavity.
