What do I do when not sealing around takeoffs and collars?

Sealing, Leakage, Mastic & Pressure Testing.1 field-polished — seal/test detail check

Takeoffs and collars are high-leak points. Seal the actual collar connection before the insulation or ceiling hides it.

Field checklist

Ask foreman

Do you want this takeoff/collar sealed and checked before insulation or ceiling close?

Do not

Do not seal only the easy side of the collar.

Why it matters

Collar leaks often become airflow complaints after ceiling close.
