Insulation compressed under strap

Insulation compressed under a strap loses thickness and creates a cold/condensation spot. Support the duct without crushing the wrap.

Stop if

• This strap is compressing the insulation. Do you want a saddle/shield or another support detail?

Watch out

• Do not cinch straps into wrapped duct.

Check

• Check all strap/contact points along the run.
• Look for flattened wrap or torn facing.
• Verify whether a saddle, shield, or trapeze detail is required.
• Rework before ceiling close if compression is obvious.
