must be new code?

I'm putting on an addtion (NJ) and the artictech put R19 insulation
between the floor joices in the crawlspace. I did not expect this,
I planed to do all the insulatin myself. My ques. is when is the appropriate
time to install this insulation, it seems it would be easier when the framers
have the joices's in but before the ply sub-floor is down, is this the right
time to install insulation? If so how is it held in place?
Thanks in advace for any advice. wavelenth.

Only problem I would see with putting ins. in after framing and before subfloor would be: After you staple the ins. to the top of the joists, the contractor may not be able to see the joists to walk on them, and could fall thru taking your insulation with him, but more importantly, hurting himself in the process.

Ya may just be better off to bite the bullet, get out the coveralls, and a helper to pass the ins. to you and crawl under after subflooring.

Energy Construction Code

Installing the insulation on the ceiling of a crawl space can be done either way, before the sub-flooring or after. In new construction it is usually done after to avoid delays, not to interfere with the other trades (elctrical, plumbing, etc.) and/or damage to the vapor barrier. If installed afterwards, they use joists hangers for this application. They are metal rods with sharp ends to hold the insulation in place. There are other methods but this is the most common.
