AAMA’s frame-deflection standard addresses the risk that foam used to air-seal window and door openings can affect fenestration frames. The 2019 edition, AAMA 812-19, clarified how foam properties and test results should be assessed; it is not the latest edition. FGIA’s 2025 coverage identifies AAMA 812-25 as the later edition, with a title focused on propellant-expanding foam sealants. For builders and installers, the practical takeaway is to select foam specifically intended for fenestration work, follow its instructions, and verify the edition and requirements that apply to the project—without treating a product’s intended use as proof of compliance.
What is AAMA 812, and why does frame deflection matter?
AAMA 812 is a voluntary practice for assessing frame deflection associated with foam sealants used to air-seal rough openings around fenestration products, such as windows and doors. Its focus is the relationship between foam behavior and changes to a frame—not a general endorsement of every foam product used in construction.

Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →One-component foam sealants are used to augment the energy-efficiency performance of fenestration installations, as Beverly Selle, chair of the AAMA 812 Insulating Expanding Foams Task Group, explained in the 2019 announcement. The same application raises a practical concern: foam-related pressure or later changes in dimensions may affect the frame. A frame that deflects can be a concern for the installed fenestration assembly, which is why the standard focuses on assessing that risk rather than simply identifying foam as an air-sealing material.
The distinction matters on a jobsite. “Foam” is not a single-use category, and a product’s suitability for an opening should not be assumed from the fact that it expands or seals gaps. FGIA’s 2025 coverage says aerosol foams have been linked to frame deflection when misapplied or when products not designed for fenestration are used. That is a general caution, not a finding about every product or a test result for a named brand.

What changed in the 2019 edition?
AAMA 812-19 revised a prior edition last updated in 2010. The 2019 update clarified foam physical properties, improved sample preparation and testing and measurement procedures, and added requirements for reporting results. Those changes were intended to make the assessment practice more explicit about what is evaluated and how findings are documented.
The 2019 coverage identified two attributes as central to foam-related frame deflection: pressure build and dimensional stability. In practical terms, the practice considers both the pressure associated with the foam and whether its dimensions remain stable. The revision refined the procedures for assessing and reporting those attributes; the coverage does not provide a numerical pass threshold, nor does it say that all foam products meet the practice.
“The AAMA 812 has been updated to clarify foam physical properties, enhance sample preparation, testing and measurement procedures, and include requirements for reporting of test results.”
— Beverly Selle, Dow Chemical Company, chair of the AAMA 812 Insulating Expanding Foams Task Group, in Building Enclosure’s 2019 coverage
That summary describes the procedural changes, not a new blanket rule for installers or a product certification. A revised assessment practice can help establish a more consistent basis for evaluation and reporting, but readers should not infer from the announcement that a particular formulation passed, failed, or was approved.

Which edition is current: AAMA 812-19 or AAMA 812-25?
AAMA 812-19 is the 2019 edition, not the latest edition identified in the published coverage. FGIA’s 2025 announcement identifies AAMA 812-25 as the later edition and says it is available through the FGIA online store.

| Edition | Scope reflected in the title | What the coverage says |
|---|---|---|
| AAMA 812-19 | Assessment of frame deflection when using one-component polyurethane foams for air-sealing fenestration rough openings | 2019 revision clarified foam properties, preparation, testing, measurement, and reporting; it followed an edition last updated in 2010. |
| AAMA 812-25 | Assessment of frame deflection when using propellant-expanding foam sealants for air-sealing fenestration rough openings | FGIA identifies it as an updated 2025 standard and lists its online store as a purchase route. |
The change in title is worth noting: the 2019 title referred to one-component polyurethane foams, while the 2025 title refers to propellant-expanding foam sealants. Do not assume the full scope, test procedures, or acceptance criteria are identical across editions based on the titles alone. The published coverage does not reproduce the full text of AAMA 812-25, and the available information does not establish its detailed methods or limits. For a formal specification, evaluation, or compliance statement, consult the edition itself rather than relying on a news summary. See Window + Door’s report on FGIA’s 2025 update and FGIA’s 2025 standards announcement.
Which foam characteristics should a product comparison examine?
A useful comparison starts with the attributes named in the practice rather than with marketing labels. First, ask whether the product is explicitly intended for fenestration, window, or door installation. Second, review the manufacturer’s stated curing-pressure behavior. Third, look for information about dimensional stability. Finally, check the application instructions and any product-specific documentation supporting a claim tied to AAMA 812.
| Comparison question | Why it matters | What not to assume |
|---|---|---|
| Is the foam formulated for fenestration? | FGIA describes fenestration formulations as intended to reduce curing pressure and maintain dimensional stability. | Intended use alone is not proof that a named product conforms to an edition. |
| What does the manufacturer say about pressure build? | Pressure build is one of the assessment attributes connected with frame deflection. | A “low-expansion” label does not supply a numerical pressure result. |
| How is dimensional stability described? | Dimensional behavior after application is part of the concern addressed by the practice. | Descriptions of stability do not guarantee zero deflection in every assembly. |
| Which instructions apply? | Installation conditions and directions are part of using the product as intended. | A generic instruction or another product’s directions cannot be substituted automatically. |
This comparison also helps separate two different questions. “Is this product marketed for windows and doors?” concerns intended application. “Was this product evaluated to AAMA 812-19 or AAMA 812-25, and did it meet the project’s requirements?” concerns documented qualification. They should not be treated as interchangeable.
How should builders and installers apply this information?
Use the standard update as a reason to be precise about product selection, instructions, and project requirements—not as a substitute for them. A practical review can help prevent a broad product description from being mistaken for evidence of performance or compliance.

- Check the project documents. Identify any specified standard edition, product requirements, or submittal expectations before choosing a sealant. If the documents reference AAMA 812, verify whether they name an edition; the 2019 and 2025 editions have different titles.
- Choose a foam formulated for fenestration use. Look for explicit window-and-door or fenestration application language in the product information. FGIA’s announcement describes formulations intended for fenestration applications and intended to reduce curing pressure and maintain dimensional stability. Those descriptions explain the product category’s aims; they are not independent test results for a specific product.
- Read and follow the product instructions. Do not assume that a general description such as “low expansion” establishes suitability for a particular frame, opening, or installation. Use the instructions applicable to the exact product and follow any more specific project requirements.
- Separate intended use from demonstrated qualification. A label saying a foam is intended for windows and doors does not, by itself, show that the product was evaluated to AAMA 812 or meets a project’s requirements. Ask for product-specific documentation when a specification or owner requires it.
- Use the full standard when making a standards claim. News coverage summarizes the updates but does not supply the complete procedures, test conditions, or acceptance criteria. Obtain the relevant edition if the work depends on its exact requirements.
- Record the edition used for decisions. Keep the edition named in the specification, the product identification, and the supporting documentation together. This avoids later confusion when a project file contains references to both AAMA 812-19 and AAMA 812-25.
- Resolve conflicts before installation. If a submittal names one edition while the project documents name another, ask the responsible project decision-maker to resolve the difference. Do not silently replace a specified edition with a newer or older one.
This process is especially useful when submittals, product literature, and specifications use different kinds of language. “Designed for fenestration” describes an intended application; a claim of conformance to a particular edition is a separate claim that should be supported by documentation. If the project calls for a specific edition, avoid substituting another edition or a general product statement without resolving that difference with the responsible project decision-maker.
What does the standard update not establish?
The announcements do not provide a named-product comparison, a list of approved foams, or evidence that every fenestration-oriented product has been assessed. Nor do they publish a numerical frame-deflection limit or enough of the test method to reproduce an evaluation. Those details should not be filled in from assumption.
Similarly, the 2019 procedural update does not show that all products sold before or after 2019 perform alike. The 2025 announcement’s descriptions of formulations intended to reduce curing pressure and maintain dimensional stability are not a guarantee of zero deflection and should not be presented as independent verification. Whether a product is appropriate depends on its own documentation, the manufacturer’s instructions, and the specific project requirements.
When discussing the standards, preserve the distinction between an assessment practice and an individual product claim. AAMA 812 is relevant to evaluating frame-deflection behavior in the stated foam-and-fenestration context. It does not, based on the published coverage, establish that a product is universally safe for every window or door installation, or that a particular installation was performed correctly.

AAMA 812 is described as a voluntary practice. That means the document itself is not presented as a universal mandate for every construction project. A contract, specification, owner requirement, or other project document can still call for a particular edition or for supporting evidence. The applicable requirement comes from those project documents, not from assuming that every job must use the practice.

The coverage also does not report a numerical pass threshold, maximum frame movement, or universal acceptance limit. Do not create a pass/fail number from the phrases “pressure build” or “dimensional stability.” If an evaluation or submittal depends on exact limits, obtain the applicable edition and review its requirements.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should a submittal or compliance statement say?
A defensible submittal should identify the exact foam product, state that it is intended for the relevant fenestration application when the manufacturer says so, and include the instructions and product-specific documentation requested by the project. If the submittal claims evaluation or conformance to AAMA 812, it should identify the edition—812-19 or 812-25—and provide supporting evidence rather than relying on a generic “window and door” label.
Specifiers and reviewers should likewise ask what is actually being claimed. A product description, an assessment report, and a statement that an installation meets a project requirement are different types of information. Keeping those categories separate makes it easier to identify missing documentation without implying that a product failed or passed when the underlying evidence has not been reviewed.

Frequently Asked Questions
Does AAMA 812 make window-and-door foam mandatory on every construction project?
The practice is described as voluntary, not as a universal project mandate. Whether a particular job requires it depends on the contract documents, applicable specifications, and project requirements.
Does a “window and door” label prove that a foam complies with AAMA 812?
No. An intended-use label is not, by itself, evidence that a named product was evaluated to a specific edition or meets a project’s acceptance criteria. Request supporting product documentation when conformance matters.
Can I use a general low-expansion foam and assume the frame will not deflect?
No such guarantee follows from the published information. FGIA warns that misapplication and products not designed for fenestration have been linked to frame deflection; follow the exact product instructions and project requirements.
What are the main attributes assessed under the 2019 update?
The coverage identifies pressure build and dimensional stability as key attributes related to foam-associated frame deflection. It does not publish a numerical pass threshold.
Is AAMA 812-19 still the current edition?
FGIA’s 2025 coverage identifies AAMA 812-25 as the later edition. Verify which edition a project specifies and obtain that edition before making a compliance claim.
The Bottom Line
Bottom line: AAMA 812-19 made the assessment of foam-related frame deflection more explicit by improving property descriptions, preparation, testing, measurement, and reporting. FGIA identifies AAMA 812-25 as the later edition. Select a foam intended for fenestration, follow its instructions, verify the required edition, and support any compliance claim with product-specific documentation.
