Step 3Stuff rolls between joists
The rolls are a bit wider than 16" which allows you to stuff them between the floor joists. They will fit pretty well just from friction but the supports are supposed to be 4" from the ends and 16" to 18" apart.
To install the supports just push up them up between the joists. The ends of the supports will dig into the wood and bow upwards into the insulation. Be sure not to compress the insulation too much, this will decrease its R-value.
To see how far apart to put the supports, I just held up a support lengthwise from the previous support since each support is about 16."
