What belongs in a glazing submittal package
A complete storefront/curtain wall package includes:
- Shop drawings: elevations keyed to the architectural drawings, plan and head/jamb/sill sections, anchorage details, and expansion provisions
- Framing system product data: system series, depths, thermal break, and finish
- Glass makeup for every glazing type: overall IGU construction (e.g., 1" IGU — 1/4" low-e over 1/2" argon over 1/4"), heat treatment, and edge/spacer details
- Performance data: U-factor, SHGC, VT per NFRC, plus STC/OITC where acoustics are specified
- Structural calculations, sealed by a licensed engineer, where the spec delegates curtain wall design
- Finish samples: anodized or painted aluminum color chips, and glass samples where specified
- Sealants and gaskets with compatibility and adhesion data
- Hardware and entrance door data where doors are in your scope
Glass makeup and energy compliance
The architect reviews glass against two masters: the specified performance values (usually driven by the energy code and the COMcheck/energy model) and appearance. Submit the specific center-of-glass and assembly values for the actual makeup, from the fabricator's or coating manufacturer's calculation tool, not the brochure's best case. Where the schedule shows spandrel, note the opacifier; where bird-safe or acoustic glazing is specified, document the frit pattern or laminate interlayer explicitly. Heat-treated lites need to be identified — tempered where safety glazing is required, heat-strengthened elsewhere to manage breakage and distortion.
The review round-trip
Glazing review runs long. The architect reviews design and performance; the structural engineer of record reviews your delegated calcs; and finish samples add a physical approval loop. Two review cycles are normal on curtain wall. Fabrication lead times — often 8 to 16 weeks after approval, longer for custom finishes and oversized lites — mean the glazing package should be among the first major submittals on the job, and the finish samples should go in even earlier.
Common rejection reasons on glazing submittals
Where glazing packages fail:
- U-factor or SHGC worse than the energy-code values the design was permitted under
- Safety glazing not identified at hazardous locations (doors, sidelites, low sills, wet areas)
- Delegated calcs missing, unsealed, or based on wind pressures that don't match the structural drawings
- Shop drawing elevations that don't match architectural opening dimensions
- Sealant submitted without compatibility/adhesion testing with the specified glass and finish
- Finish sample skipped, then the delivered anodized color doesn't match adjacent work
How Submittal.App builds the glazing package
Your fabricator produces the shop drawings and calcs; Submittal.App assembles the rest and keeps the whole package coherent. The AI Builder pulls system and product data sheets, organizes glass types against the glazing schedule, merges the fabricator's PDFs, and outputs a clean package with cover sheet and TOC. Versioning keeps resubmittals straight when round two arrives.
