Insulation creates insufficient clearance at ceiling grid
Insulation can steal ceiling-grid clearance after duct looks fine bare. Check finished clearance before the ceiling closes.
Watch out
- Do not wait until ceiling tile is going in to discover the wrap will not fit.
Check
- Measure duct-to-grid clearance with insulation thickness included.
- Check fittings, corners, dampers, and access panels.
- Look for places insulation will rub T-bar, lights, or ceiling tile.
- Flag tight spots before wrap or ceiling install.

Say this to your foreman
With insulation added, this duct gets tight to the ceiling grid. Do you want this checked before wrap/ceiling?
