Don't know about other parts of the country, but here in Texas English is not the common language and the building trades workmanship makes one think...

We're have a home built which has joists 24" OC, builder used 1/2" sheetrock, over which we had 1" (theoretical) foam applied. Today fortunately the insulator didn't have enough Cellulose to do the job so they'll return next week. Nails are smooth shank, no screws were used. Furthermore, we're with 3 weeks of closing.

The issue/question is whether the foam added enough regidity to the ceiling for the weight of the R-38 insulation.

You guys always have good story, so I'll look forward to your response.

Thank you.

Heck yes!

It's what they use for SIPs. If they've sprayed that ceiling and the foam has bonded to the lower truss chords and to the drywall, that's going to be one very stiff ceiling and should be able to handle the R38 cells easily, smooth shanked nails and all.

ONE TEAM - ONE FIGHT!!!
