Replacing batt insulation in tall crawlspace
new here and just an avid DIY home homeowner
In the process of installing new hardwood floors, I will have to reinforce the floor from below, because rising existing with 1/2″ plywood will cause some clearances issues.
With that said, the crawlspace is 6 feet high, has poly sheeting covering the ground, and foundation vents on three sides – one side joins the garage and and a slab floor room ( this is a split level home, two levels stacked and a mid level, that provides the crawlspace). After buying the house over a decade ago ( it’s from early 90’s), I applied rigid foam and sealant on the wall joists, and drylok around the foundation walls after sealing a few hairline cracks.
There are no condensation, mold or any flooding issues
The batt insulation is in good shape, but has I have to removed in order to install the in-between joists reinforcement; so this would be a good time to consider a better alternative.
The house is in zone 6
I am thinking too, in applying rigid foam sheeting on the walls, but most important to me right now, is what kind of alternatives would be suitable, if any at this point, to the non-paper faced batt?
There is no piping running thus the joists: only some electric , phone and cable wiring, running mostly on the joists and ofcourse the flexible ducting.
Floor joist are 2×6, @ 16″ O.C. on a +/-30×20 space (four column supports)
Thanks for the help
