# Explain exterior insulation from assembly records rather than photographs.

An exterior insulation specification page identifies the documented layer, wall zone and assembly revision before describing its status. Separate specified scope, installation photographs and confirmed as-built records. A finished facade cannot verify a concealed layer. Publish only what the applicable documents and responsible project review support, with unresolved conditions stated clearly.

## Which wall detail supports the insulation description?

Begin with the wall zone the buyer is asking about. Find the applicable assembly detail and its revision. Record the layer label exactly as the confirmed source identifies it. Avoid a whole-home statement when your evidence describes only one wall zone or a proposed assembly.

A public summary should distinguish insulation, exterior finish and framing. Keep each description connected to its own recorded role. Do not treat the exterior finish name as an insulation specification. Do not use the insulation label to identify the structural wall.

Trace the detail reference through the applicable project records. Ask the responsible reviewer whether the detail applies to that elevation and current revision. A typical detail in an older drawing set should not become a current project fact without that connection.

The [standard specifications page guide](/articles/builder-websites/standard-specs-page/) explains inclusion and option labels. Use those labels only where your records support them. A layer specified for one project does not automatically belong to your standard scope for other plans.

### What should you do with an ambiguous layer label?

If the detail uses a label the editor cannot identify, ask the qualified project reviewer to interpret it. Keep the original reference in the working record. Do not identify insulation from the color of a board or the position of a line in a photograph.

If the record establishes only a generic layer category, keep the public description at that level. If product identity remains necessary to answer the buyer's question, hold that part of the answer. Do not borrow a product document from a similar project.

Use a separate record for each zone when assembly details differ. A front-wall record should not silently control an addition, porch enclosure or rear wall. The page can describe the confirmed zone without implying a single assembly everywhere.

## What does each evidence state establish?

Separate the question “What is specified?” from “What was installed?” A current assembly detail can support specified intent. A photograph during installation documents the view and condition shown at that stage. A confirmed as-built description needs records and review connecting it to the completed project.

Use these three editorial states when preparing the public summary. They are proposed writing labels, not official inspection categories or completion certificates.

| Evidence state | Useful support | Limit on the public statement |
| --- | --- | --- |
| Specified | Applicable wall detail, revision and confirmed layer label | Describes intended scope rather than completed installation |
| Photographed during installation | A located construction photograph linked to the relevant records | Describes the shown area and stage, not every concealed condition |
| Confirmed as built | Applicable completion records and responsible project confirmation | Describe only the scope those records confirm |

A photograph does not advance a specified layer to confirmed as built by itself. Ask who established the photograph's location and relation to the assembly detail. If the image cannot be located confidently, leave it out of the installation evidence field.

A finished facade photograph may document exterior appearance. It cannot identify the concealed insulation layer through the finish. Keep the finished photograph's caption about what it shows. Use the [exterior siding page guide](/articles/builder-websites/exterior-siding-spec-page-content/) for visible finish scope and elevation labels.

Do not turn an installation image into a product endorsement. Even when the reviewer confirms a visible label, the photo supports only the documented area and stage. Check the applicable product record before publishing product identity or attributes.

### How do conflicting revisions affect the wording?

If the wall detail and completion record differ, hold the disputed layer description. Ask which record establishes the completed condition. Keep both references in the internal record until the reviewer resolves their relationship. A later file date alone cannot establish the answer.

After resolution, preserve the evidence state in the public wording. “Specified” should remain specified if completion remains unknown. Do not replace that boundary with a general assurance about construction quality.

## How do you prepare an exterior layer record?

Copy this worksheet for each wall zone you intend to describe. It is an original editorial proposal for website preparation. It supplies no assembly design, installation method or inspection instruction. Keep the technical interpretation with the responsible qualified project reviewer.

```
Exterior layer record
Wall zone:
Assembly detail:
Layer identity:
Product document:
Installed evidence:
Unknown condition:
Reviewer:
Public wording:
```

In wall zone, identify the exact region the source covers. In assembly detail, record the applicable reference and revision. In layer identity, use the supported label. Keep insulation, finish and framing references distinct even if the same drawing contains all three.

The product document field should identify the exact applicable document when product identity is confirmed. Record an unresolved product as unknown. Do not select a convenient manufacturer sheet to make the worksheet look complete. An available document does not prove that its product belongs to this project.

In installed evidence, record the source and the scope it establishes. If none exists, say so in the working record. Use unknown condition for questions the public summary cannot answer. Examples include coverage outside the documented zone or a completed condition awaiting confirmation.

Record the person responsible for confirming the source in reviewer. Keep personal contact details out of the public excerpt. The public wording field should state the layer's supported status without converting open questions into implied promises.

1. Identify the wall zone and applicable assembly detail.

2. Confirm the revision with the responsible project reviewer.

3. Separate the insulation label from finish and framing descriptions.

4. Link any confirmed product identity to its exact applicable document.

5. Classify the available evidence as specified, photographed or confirmed as built.

6. List unresolved conditions and questions requiring qualified review.

7. Draft a public statement that preserves the evidence state.

8. Compare the proposed page and image captions with the reviewed record.

If a buyer asks about another wall zone, start another row. Do not stretch an existing row to cover it. A short summary for one supported area answers more accurately than an expansive description assembled from unrelated records.

## What would a documented project example say?

This example is fictional and describes no actual home, builder or AgAI Labs construction work. Suppose the current front-wall detail identifies an exterior insulation layer. The reviewer confirms that the detail applies to the named wall zone. Product identity and the completed concealed condition remain unconfirmed.

A construction photograph shows the front wall during work, but its connection to the layer record remains unresolved. A finished photograph shows the facade. Neither image closes the missing connection. The worksheet therefore records the layer as specified and leaves installed evidence unconfirmed.

The product document field remains unknown. The unknown condition field names the completed layer and the photograph's relationship to the wall detail. The reviewer receives those specific questions. No default material, thickness or performance value fills the empty fields.

A fictional public-page excerpt could read: “The current assembly record specifies an exterior insulation layer at the front wall zone. The completed concealed condition and product identity are not confirmed in this summary. The finished facade photograph shows exterior appearance; it does not verify the layer behind it.”

That excerpt describes a limited evidence state rather than a finished assembly claim. Replace every fictional condition with your own reviewed facts before publication. If you cannot explain the limitation clearly, omit the affected feature statement until the missing record is available.

### What changes when completion records become available?

Ask the reviewer which wall zone and layer the new records confirm. Check product identity separately. Completion evidence for one zone may leave another unresolved. Update only the supported statement, and preserve the source references used for the earlier specified description internally.

When confirmed, an installation photograph may illustrate the relevant construction stage. Its caption should name the located zone and stage. A later as-built confirmation does not change what the photograph itself shows.

The [W3C informative images tutorial](https://www.w3.org/WAI/tutorials/images/informative/) explains that an image's text alternative should convey its information in context. Use that guidance for the located image. Keep the evidence state in visible copy rather than expecting alternative text to carry the whole explanation.

Do not write alternative text that names an unconfirmed insulation product. Describe only the image's supported contribution to the page. If the photograph serves no useful explanatory purpose after those limits, the article can explain the records without adding an image.

## Which questions should remain outside the public claim?

Keep performance values out of the description unless exact applicable evidence supports them. Do not assign a default R-value to an unidentified layer. Do not turn a product statement into a claim about the entire wall or completed home.

Record questions about product identity, assembly compatibility and project-specific application for qualified review. Provide the wall detail and current source references with each question. This article supplies no installation recipe and makes no moisture, energy, comfort or safety assurance.

The [Federal Trade Commission's truth-in-advertising guidance](https://www.ftc.gov/news-events/topics/truth-advertising) addresses truthful advertising, misleading statements and scientific evidence when appropriate. Use that evidence boundary when selecting public claims. It does not approve a proposed worksheet or verify any assembly in your project.

If a buyer asks about the brick finish outside the concealed layer, use the separate [brick exterior specification page guide](/articles/builder-websites/brick-exterior-spec-page-content/). Finish coverage and insulation identity need different supporting records. Keep each answer close to the relevant source and view.

The [Owned website stage](/process/owned-website/) connects this explanation with project and specification pages. The [custom builder website pages guide](/guides/custom-builder-website-pages/) organizes those pages. The [builder websites library](/articles/builder-websites/) covers related buyer questions.

When records change, review the layer statement, product reference and image caption together. Keep an unresolved condition explicit until the reviewer supplies the missing evidence. Do not let a new facade photograph silently change a specified layer into a completed feature.

## What else should an exterior insulation page clarify?

### Can a finished facade photograph verify exterior insulation?

A finished facade photograph cannot verify a concealed exterior insulation layer. Use the applicable assembly records and responsible project confirmation. Label the photograph as an appearance view rather than evidence of the concealed layer.

### What is the difference between specified and confirmed as built?

Specified exterior insulation describes the intent supported by the applicable assembly detail. Confirmed as-built wording requires records and review establishing the completed condition. Keep the specified label when completion remains unconfirmed.

### Should an exterior insulation page publish an R-value?

An exterior insulation page should omit an R-value unless exact applicable evidence and responsible review support the proposed statement. Do not assign a default value to an unidentified product or extend a product value to the complete wall.

### Does one confirmed wall zone establish insulation throughout the home?

A confirmed insulation record for one wall zone establishes only the scope it covers. Check other zones against their applicable assembly details and completion records. Do not convert one project's documented layer into a builder-wide standard.
