Spray foam insulation cause a drying problem

[Desk Jockey]

We had a loss that had sat 3-4 days and wasn’t found until the homeowner came back in town from a trip. They had 8-inches of water standing for several days, which allowed the water to wick into the drywall.

We removed the drywall and insulation 2-ft up, but the wall still was not drying as it should. What we found was moisture had wicked beyond what was apparent, and where the foam and the paper met the moisture was trapped.

The foam doesn’t allow air flow and the backside of the drywall is not accessible with our removing the foam.

We had to go in and scrape off the spray foam and it dried over night. If you run into spray foam, you will most likely need to remove it for it to dry between itself and the paper.

Good to know thanks. Was this foam only part of the way up the wall where you couldn't see it after you removed the 2ft of drywall?

As far as we can tell it come all the way up the wall. The affected room was a music room and I assume it was added as a sound barrier
