American Gypsum: products, competitors, and EPD coverage

Who American Gypsum is

American Gypsum manufactures gypsum wallboard and related panels across the U.S., with listed locations in Albuquerque, Bernalillo, Duke, Georgetown, and Gypsum, which signals five plants (American Gypsum, 2025). Their catalog centers on interior wallboard and exterior sheathing for commercial, multifamily, and residential work.

What they sell, in plain English

The range covers regular gypsum board, fire‑rated Type X and Type C boards, mold and moisture resistant M‑Bloc variants, glass mat exterior sheathing, shaftliner panels, soffit and ceiling boards, plus abuse and impact resistant boards. That translates to several distinct product families and dozens of SKUs, not a niche one‑trick lineup.

Think of it like a well stocked toolkit. Drywall pros can build full interior partitions, chases, and exterior envelopes without leaving the brand.

EPDs you can actually find today

American Gypsum’s EPD page points to the Gypsum Association’s industry‑wide EPDs for 5/8 in. Type X gypsum board and for glass mat panels, rather than product‑specific EPDs for American Gypsum‑branded SKUs. The Type X industry EPD was issued April 28, 2020 with a five‑year validity window that ended April 27, 2025 (Gypsum Association Type X EPD, 2020). The glass mat industry EPD shows a 2016 issue and a five‑year validity that ended in 2021 (Gypsum Association Glass Mat EPD, 2016).

That means what’s linked today is industry‑wide and, based on the documents, out of validity. If a refreshed industry EPD or any product‑specific EPDs exist elsewhere, they are not obvious on the public site as of November 27, 2025.

Why that matters in specs and credits

LEED v4.1 values product‑specific Type III EPDs more than industry‑wide declarations. Product‑specific EPDs are counted as 1.5 products and industry‑wide as 1.0 toward the EPD tally in many project types (USGBC, 2024). When a submittal set needs every eligible product to punch its weight, missing or outdated EPDs add friction.

If you’ve ever tried to stream a show with spotty wifi, you know the feeling. The content may be great, but the buffering hurts the experience. Procurement feels the same when an otherwise solid board lacks current, product‑specific documentation.

Coverage, at a glance

Based on the public pages above, American Gypsum’s transparency posture today is stronger on HPDs than EPDs. The HPD page lists multiple boards with documents ready to download, which helps on material ingredient credits, while the EPD page links to industry‑wide PDFs that appear out of validity (American Gypsum HPD page, 2025). In rough terms, product category coverage is broad, SKU coverage by product‑specific EPD looks low.

A likely best‑seller without a product‑specific EPD

Fire‑rated Type X wallboard is a workhorse in offices, healthcare, education, and multifamily. American Gypsum’s lineup includes FireBloc Type X and M‑Bloc Type X, yet we did not find a product‑specific EPD for these boards on the site. Project teams that must meet EPD counts often pivot to comparable boards with current, product‑specific EPDs.

Competitor example you’ll see in submittals: National Gypsum publishes plant‑specific EPDs for multiple Fire‑Shield and EVOLVE X Fire‑Shield boards, plus other families, directly on its EPD hub (National Gypsum EPDs, 2025). That makes the swap easy for specifiers when EPD weighting is tight.

Who they compete with most

You’ll typically see American Gypsum bid against USG, CertainTeed, National Gypsum, Georgia‑Pacific, and PABCO for like‑kind drywall, shaftwall, and sheathing packages. Each of these peers has a visible footprint of product‑specific EPDs for key gypsum categories on their public sites or program‑operator portals, which helps them qualify more cleanly on EPD‑sensitive projects. The takeaway is not that performance differs, it is that documentation often decides momentum.

How to close the EPD gap fast

If the priority SKUs lack product‑specific EPDs, pick the few that drive most of your volume and start there. A good LCA partner will match the dominant PCR used by competitors, map the right operator for your target markets, and handle the cross‑plant data wrangling with minimal time drain on operations. That white‑glove approach is what frees engineering and plant teams to keep lines running while the paperwork moves. It’s definately the stress‑saving path.

What to do this quarter

Identify the top three board families by revenue and by spec frequency. Confirm whether each has a current, product‑specific Type III EPD published and easy to download. Where there’s only an industry‑wide EPD, plan a product‑specific EPD first, since it carries more weight in LEED v4.1 counting (USGBC, 2024). Use your five listed plants as a guide to stage data collection by facility so future updates are smooth (American Gypsum, 2025).

The practical finish

American Gypsum has the product breadth to win across interiors and envelope. To convert that breadth into more wins on EPD‑sensitive projects, make product‑specific EPDs visible for your cornerstone boards and keep them current. It’s the difference between having a great track and making sure it shows up at the top of the playlist when the DJ hits search.
