23 07 00 HVAC Insulation: Common Contradictions and RFI Guide
Duct and pipe insulation specs conflict with energy code requirements and fire rating requirements at duct penetrations.
Most HVAC Insulation contradictions trace to the same root: the specification and the drawings are produced by different people at different stages, and never fully reconciled before the set goes out. By the time the conflict is found in the field, it is an RFI, a delay, or a change order.
Lintel cross-references section 23 07 00 against your full drawing set, schedules, and the rest of the project manual, flagging every disagreement with a citation to the exact page so it is resolved in review.
Common contradiction types
Insulation thickness vs. energy code
A frequent hvac insulation conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Fire-rated penetration conflicts
A frequent hvac insulation conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Vapor barrier requirement gaps
A frequent hvac insulation conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Frequent RFIs
- Insulation thickness not meeting energy code
- Duct insulation not rated at fire-rated penetration
- Vapor barrier requirement missing from spec
