Read Exterior Wall, Window, Door, and Flashing Details

A. Finished-Package Specification

Deliverable set: one wall-type index cross-referencing every exterior wall type to its governing sections and details; one envelope-detail checklist organized by wall type, base, floor line, roof line, opening, penetration, attachment, material transition, testing, and inspection; one penetration register; and one envelope-related unresolved-item list feeding the Chapter 17 conflict register.

B. Deliverable Schedule (Component Schedule)

Component	Quantity	Source	Required Fields	Preparation / Purpose
Wall-type index	1	Wall sections, wall schedule, general notes	Wall type tag, layer summary, governing sheets	Establishes which details apply to which wall
Envelope-detail checklist	1	Wall sections, opening details, flashing details, specifications	Location, layer order, function, continuity requirement, source	Traces water, air, thermal, vapor, structural, and finish continuity
Penetration register	1	Envelope details compared with MEP and elevation documents	Type, location, support, flashing detail, trade, field-verification need	Confirms every penetration has a documented flashing or sealing method
Unresolved-item list	1	Discrepancies found while building the above	Item, description, affected location, requested action	Feeds the Chapter 17 conflict register and RFI process

C. Source Material Takeoff

• Primary source: current exterior wall types, wall sections, opening details, flashing details, exterior elevations, specifications, and approved product submittals available for the project at the time this chapter begins.
• Supporting source: the Chapter 1 navigation package, the Chapter 5 elevation checklist, the Chapter 6 assembly interpretation table, and the Chapter 8 opening register.
• Reference tools: one straightedge and a consistent set of markup colors for tracing continuity.
• Recording medium: one document-control log or spreadsheet capable of holding the four deliverable components listed in Section B.

D. Acceptance Standards

Check	Standard
Wall-type completeness	Every exterior wall type shown on the plans or elevations appears in the wall-type index with its governing sections and details identified
Layer-function accuracy	Every layer recorded as performing a water, air, thermal, vapor, structural, fire, or acoustic function is supported by the documents or approved product information, not assumed
Continuity tracing	The WRB and air barrier are traced without a documented break at every base, floor line, roof line, opening, and penetration reviewed
Opening-detail matching	Every window and door detail used is confirmed to match the correct wall type, opening type, and manufacturer information
Penetration coverage	Every documented penetration has a recorded flashing, sleeve, boot, or sealant reference, or is logged as unresolved
Unresolved-item capture	Every discontinuous barrier, reverse lap, unsupported flashing, or missing end condition encountered is recorded, not silently resolved

E. Preparation — Confirm Documents and Wall Types

1. Confirm current exterior wall types, wall sections, opening details, flashing details, exterior elevations, specifications, and approved product submittals. Verify each against the Chapter 1 document-control register before use.
2. Identify each exterior wall assembly by type, orientation, exposure, cladding, structure, and related detail set. Populate the wall-type index with one row per distinct wall type.

F. Wall-Layer Continuity Tracing

1. Trace layers from interior finish through framing, insulation, sheathing, air barrier, water-resistive barrier, drainage space, attachments, and exterior finish. Record the layer order for each wall type in the envelope-detail checklist.
2. Identify which layer performs water, air, thermal, vapor, structural, fire, acoustic, and finish functions as documented. Record only the functions the documents or approved product information state.
3. Do not assume that a membrane serves functions not stated by the documents or product approval. Where a function is not stated, record it as unresolved rather than assumed.

G. Transition Details

1. Locate base-of-wall, foundation, slab-edge, floor-line, roof-wall, parapet, soffit, balcony, deck, and material-transition details. Record each transition condition present in the project.
2. Trace the drainage plane and air barrier through each transition. Confirm the WRB and air barrier connect from the wall section into each transition detail without a documented gap.
3. Identify WRB laps, terminations, shingle sequencing, transition membranes, sealants, tapes, flashings, and mechanical attachments. Record the lap direction and sequence for each transition.

H. Window Details

1. Locate window head, jamb, sill, pan, receptor, mullion, and perimeter-seal details. Record each detail against its corresponding window tag from the Chapter 8 opening register.
2. Identify rough opening, framing, sill support, pan slope, end dams, drainage, head flashing, back dam, and interior air-seal references where shown. Record only the values the documents provide.
3. Match window details to the correct wall type, window type, installation method, and approved manufacturer information. Confirm the match before adding the detail to the checklist.

I. Door Details

1. Locate exterior door head, jamb, sill, threshold, pan, landing, accessibility, and perimeter-seal details. Record each detail against its corresponding door tag from the Chapter 8 opening register.
2. Identify threshold support, drainage, flashing, fastener, sealant, and interior-to-exterior elevation relationships. Record only the values the documents provide.
3. Match door details to the opening schedule, hardware, wall type, and manufacturer information. Confirm the match before adding the detail to the checklist.

J. Cladding Clearances and Ventilation

1. Locate siding or cladding clearances above grade, roofs, decks, slabs, paving, flashings, openings, and material transitions. Record each documented clearance condition.
2. Record only the clearances documented by the project or approved product information. Do not add a clearance value from general trade familiarity.
3. Identify rainscreen, furring, drainage mat, masonry cavity, weeps, vents, bug screens, closure pieces, and ventilation paths. Record each drainage and ventilation provision shown.
4. Do not seal or block intentional drainage and ventilation openings. Flag any checklist item that would conflict with a documented weep or vent.

K. Penetration Register

1. Locate penetrations for pipes, ducts, conduits, cables, lights, receptacles, meters, hose bibbs, and equipment attachments. Record each penetration location.
2. Identify penetration sleeves, blocks, flashings, boots, gaskets, sealants, and support references. Record the documented method for each penetration.
3. Compare penetration locations with MEP and elevation documents. Confirm each penetration shown on MEP or elevation documents has a corresponding envelope detail or is logged as unresolved.

L. Structural and Attachment Interfaces

1. Locate balcony, deck ledger, porch, stair, canopy, awning, and exterior-mounted equipment interfaces. Record each interface condition present in the project.
2. Verify structural attachment and envelope integration are both addressed. Confirm the detail shows both the structural connection and the surrounding envelope continuity, or log the gap as unresolved.

M. Product and Testing Requirements

1. Identify compatible-material, primer, substrate, temperature, moisture, cure, adhesion, and warranty references. Record only values the documents or manufacturer information provide.
2. Identify required mockups, water tests, adhesion tests, manufacturer inspections, and pre-cover inspections. Record each requirement in the checklist's testing and inspection column.

N. Cross-Discipline Comparison and Closeout

1. Compare details with site grade, roof drainage, foundation, window and door schedules, and wall sections. Confirm elevations, materials, and openings remain consistent across all referenced documents.
2. Identify discontinuous barriers, reverse laps, unsupported flashings, incompatible transitions, missing end conditions, or details that do not match the field assembly. Record each on the unresolved-item list.
3. Create an envelope-detail checklist organized by wall type, base, floor line, roof line, opening, penetration, attachment, material transition, testing, and inspection. Finalize the checklist built through Sections F through M.
4. Attach sheet, detail, specification, submittal, evaluation report, and manufacturer references. Confirm every checklist row cites its governing source.
5. Prepare RFI-style questions for missing continuity, conflicting layers, unclear openings, unaddressed penetrations, or material incompatibility. Draft one neutral question per unresolved item.
6. Review the checklist for every exterior wall and opening condition represented in the project. Confirm no wall type, opening, or penetration from the wall-type index or opening register is missing from the checklist.
