EPDs for Fenestration Accessories in the US

What falls under “fenestration accessories”

Think the parts that make openings work. Window and door hardware, louvers, curtain wall frames and infill accessories, glazing gaskets and spacers. In practice, EPDs here often use hardware or cladding PCRs and can pull in adjacent items that live inside the window and curtain wall package.

The 2021–2025 snapshot for the US

Across the last five calendar years we see 13 currently valid EPDs from 5 manufacturers using 3 program operators and 5 different PCRs. The latest addition is Airolite’s K6746 Drainable Blade Louver, issued Feb 6, 2025 with Smart EPD using the “Part B: Insulated Metal Panels, Metal Composite Panels, and Metal Cladding” rule and an expiry on Feb 6, 2030.

Why this matters commercially. On many projects, a product without a product‑specific EPD faces a penalty in carbon accounting which nudges specifiers toward options with third‑party verified declarations. An EPD can keep you in the conversation on bids where embodied carbon is tracked under evolving frameworks like LEED v5 drafts that emphasize product‑level transparency (USGBC, 2024).

Momentum by year

A quick view of release timing helps with launch planning and competitive reads.

Year	EPDs issued
2021	2
2022	7
2023	0
2024	3
2025	1

Activity peaked in 2022, paused in 2023, then resumed in 2024. If you want to land a new EPD before large renewal waves, 2026 is a good window.

Who publishes the most EPDs here

Manufacturers represented include National Ready Mix with 6 EPDs, H. B. Fuller Company with 3, Vetrotech Saint‑Gobain with 2, and single EPDs from Airolite and ATENA S.p.A. This spread shows two patterns. Some EPDs tie to builders hardware and louvers that specifiers read as classic fenestration accessories. Others sit adjacent in the assembly where adhesives, sealants, and cladding elements live alongside glass and frames.

Program operators used in the US set

Operator choice signals convenience, verification approach, and market familiarity.

• UL accounts for 6 EPDs concentrated in one manufacturer, a sign of deep category focus within a single portfolio.
• EPD International AB carries 3 EPDs coming from 2 manufacturers, showing cross‑manufacturer adoption.
• Smart EPD LLC hosts 4 EPDs from 2 manufacturers and published the most recent louvers EPD cited above.

For teams deciding where to publish, all three operators are well known to US specifiers. UL and EPD International align with EN 15804 based PCRs that map to A2 requirements in recent cycles, while Smart EPD supports US‑centric programs and fast publication flows. EN 15804+A2 became the prevailing baseline for construction product EPDs in Europe in 2019, and its influence is visible in US operator PCRs used by global brands (CEN EN 15804+A2, 2019).

PCRs behind the declarations

The PCR is the rulebook of Monopoly. Ignore it and the game falls apart. Across this category we see five distinct PCRs in use, with expiries that drive renewal timing.

PCR name	EPDs	Latest expiry
Part B: Builders Hardware	6	Jul 1, 2027
PCR 2012:01 Construction products and services (EN 15804 A1)	2	Jan 30, 2027
PCR 2019:14 Construction products (EN 15804 A2) v1.3.3	1	Jul 27, 2027
Smart EPD Part A Product Category Rules v1.0	3	Aug 14, 2029
Part B: Insulated Metal Panels, Metal Composite Panels, and Metal Cladding	1	Feb 6, 2030

Two trends stand out. First, builders hardware Part B rules are the workhorse when hardware is the lead item. Second, A2‑aligned PCRs are in the mix and important if you sell globally or to firms standardizing on A2. EN 17610 defines category requirements for building hardware under EN 15804 A2 and is increasingly referenced by operators that publish in Europe and the US for global portfolios (CEN EN 17610, 2022).

Renewal watch for planning cycles

Here is what expires soon among the currently valid set.

• 2026 shows 2 expiries. One from the builders hardware Part B group and one from PCR 2012:01 A1.
• 2027 shows 7 expiries. Five from builders hardware Part B plus single expiries under PCR 2012:01 A1 and PCR 2019:14 A2 v1.3.3.
• 2028 shows 0 expiries.
• 2029 shows 3 expiries. All tied to Smart EPD Part A v1.0 on Aug 14.
• 2030 shows 1 expiry. The metal cladding Part B used by the 2025 louver on Feb 6.

If your competitor’s declaration sits inside the 2026–2027 window, a Q1 2026 start can put your EPD live while theirs is being refreshed. That makes bids easier because reviewers dont need to reconcile timing gaps.

The role of EPD consultants and service providers

12 of the 13 EPDs in this set were released with help from an external EPD service provider. That level of third‑party involvement reflects the reality of data wrangling across plants, product options, and supplier footprints. If speed and completeness matter, partnering with an EPD consultant like Parq keeps senior engineers focused on manufacturing while the paperwork gets done to standard.

Operator diversity vs single‑portfolio concentration

UL’s 6 EPDs are all from one manufacturer, which suggests a concentrated program that scales inside a single portfolio. EPD International AB and Smart EPD show broader manufacturer diversity at lower counts. If you want network effects, publishing where competitors publish can help comparability. If you want a lighter queue, an operator with fewer competitors in your niche can be faster to verify.

Notably absent manufacturers in Division 08

As of Jan 22, 2026 we did not find current, US‑market EPDs under MasterFormat Division 08 in the public registry for several large fenestration accessory players including C. R. Laurence, Quanex, AmesburyTruth, and SFS. They may have declarations in adjacent categories, in other regions, or in progress. If you compete with any of them, the opening to be the first with a product‑specific EPD in a given subcategory is real.

Picking the right PCR without second‑guessing

Start with the competitive landscape. If direct peers use builders hardware Part B, that is often the quickest path to apples‑to‑apples comparisons. If your product reads more like cladding or a louver assembly, that cladding Part B can fit well. If your brand sells globally or aligns with A2‑based comparability, use an A2 family PCR that maps to EN 15804+A2 expectations. When in doubt, talk to the operator you prefer and confirm reviewer expectations. We are operator‑agnostic and see UL, Smart EPD, and EPD International all working for US fenestration.

What to do next in 2026

• Decide the product scope and reference year now so plant data is clean for modeling.
• Pick the PCR based on competitor fit and expiry runway so your EPD stays current through key bids.
• Choose an operator that your channel trusts and that has recent category experience.
• Set a renewal calendar aligned to the 2026–2027 expiry bulge above, then build refresh work into product roadmap gates.

Notes and data access

This article is based on the global public registry that most architects and specifiers rely on. Due to loading delays, some declarations from the last half of 2025 may not appear yet.

Regulatory and standards context evolves. LEED v5 is in development and continues to emphasize embodied carbon and product‑specific transparency, which keeps EPDs central to many bid packages (USGBC, 2024). EN 15804+A2 has guided many of the PCRs cited here since 2019 (CEN EN 15804+A2, 2019). For building hardware families, EN 17610 sets category‑specific rules that influence operator PCRs used by global manufacturers (CEN EN 17610, 2022).
