08 80 00 Glazing: Common Contradictions and RFI Guide
Glass type, U-value, and SHGC requirements in the glazing spec conflict with energy compliance documentation and architectural schedules.
Most Glazing 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 08 80 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
U-value vs. energy compliance
A frequent glazing 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.
SHGC conflicts
A frequent glazing 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.
Glass type vs. frame spec
A frequent glazing 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
- Glazing U-value not meeting energy model
- SHGC requirement conflict between spec and energy compliance
- Glass type not compatible with specified frame system
