Welcome to the transparency arena
Senior Architectural entered the EPD column in July 2025. The first release covers the SF52 curtain wall system, followed by a December wave that extends coverage across core PURe window and door families. All five declarations are current and third‑party verified.
What they published
Scope reads like system families, not one‑off SKUs, which is ideal for schedules that mix sizes and options. The five EPDs now live are:
- SF52 Mullion Drained Curtain Wall System (issued July 2025)
- SF52 Zone Drained Curtain Wall System (issued December 2025)
- PURe Casement Aluminium Window System (Top‑Hung Open Out)
- PURe Tilt and Turn Aluminium Window System (Open In)
- PURe Aluminium Commercial Door System (Open Out)
In plain terms, that puts the main Senior envelope workhorses on the record for carbon. Think of an EPD like a box score after the game. No drama, just the numbers teams need.
Who verified them and which rules apply
All five declarations are published with EPD Hub, a program operator focused on EN 15804 and ISO 14025 alignment (EPD Hub overview). The curtain wall EPDs cite EPD Hub’s Core PCR v1.1, while the PURe window and door EPDs reference EN 17213 for windows and pedestrian doorsets. A separate LCA consultant is not named in the public record for these documents.
Work for Senior Architectural or competing against them?
Follow us for a product-by-product analysis of their EPDs to see which systems get spec'd and where they stand against Kawneer and Schüco.
Why this matters on specs right now
On projects modeling embodied carbon, products without a product‑specific EPD often get penalized in whole‑building accounting, which can nudge them out of contention when targets are tight. With system‑level EPDs for SF52 and the PURe family, Senior’s package is easier to carry through prequal, design development, and submittals without detours to generic proxies. Teams keep the conversation on performance, aesthetics, and delivery.
Competitive snapshot
This move drops Senior into the same EPD conversation as established system houses.
Kawneer has a broad set of current EPDs spanning curtain wall, windows, and storefront frames via UL. That is deep coverage across similar categories.
Schüco lists multiple current EPDs for selected façade and window systems plus aluminium profiles. Coverage is solid on flagship assemblies.
Reynaers shows at least one current system EPD for a leading window platform. Coverage appears more selective versus a full curtain‑wall plus window plus door trio.
Net effect. Senior has clearly entered the transparency arena with system‑family declarations where specs live, catching up to peers on façade and window assemblies and pressing an edge where competitors’ coverage is thinner in like‑for‑like systems.
A quick note on product scope choices
These read as system EPDs that reflect the aluminium assemblies Senior actually supplies. For specifiers, that improves comparability against rival system EPDs and avoids apples‑to‑oranges reads that can happen when glass or unrelated components sneak into the denominator. Good LCA hygiene shows up later as fewer RFI loops.
Where to find the documents
Senior has publicly highlighted the SF52 curtain wall EPD on its site and points to NBS Source for downloads. See the company’s news post “EPD Published for SF52 Aluminium Curtain Wall System” for the primary reference and contacts if you need the files today (Senior Architectural Systems, 2025) (Senior site post). If a central “EPDs” page does not yet exist, adding one will boost visiblity for architects and QS teams hunting links mid‑tender.
What smart next steps look like
Keep momentum by extending coverage to adjacent variants commonly scheduled with SF52 and PURe, and align reference‑year data across the set. Pick an LCA partner who takes on the heavy data lift so engineering time stays on product. That is how manufacturers turn EPDs from paperwork into predictable spec wins.
The takeaway
Senior Architectural now has verified EPDs covering its headline curtain wall and PURe window and door systems. The debut started in July 2025 and widened in December. For bids that require product‑specific, third‑party‑verified data, that’s the green light to specify without reaching for generic stand‑ins. It also signals Senior intends to compete on transparent performance where it counts most, in the schedule and the submittal set.
