Congrats, Heron Joinery on first EPDs

What just launched

Heron Joinery has published four product EPDs, starting in April 2025 and rounding out through late 2025. The first covered a Double Glazed Timber Casement window in April, followed by a Sliding Sash Timber Window, a Traditional Glazed Timber Double Door‑set, and a Traditional Timber Doorset 54mm. The scope reads as product families rather than single SKUs, which helps specifers map common variations without hunting for separate PDFs.

All four sit with the program operator EPD Hub. Three reference EN 17213 for windows and pedestrian doorsets and one uses the EPD Hub Core PCR. Records indicate external LCA software support on at least one declaration, with verification handled through the operator’s normal process.

Why this matters on bids

On projects that model embodied carbon, a product without a product‑specific EPD is often penalized with conservative defaults in whole‑building tools. A verified EPD replaces those placeholders with measured impacts, which makes timber windows and doors more competitive on submittals where EN 15804 formatting is expected. Teams move faster when paperwork matches the spec question in plain terms.

Where Heron Joinery competes

Heron Joinery manufactures premium bespoke timber windows and doors for residential, heritage, social housing, and commercial work across the UK and Ireland. Their portfolio spans 14 window and door styles and the firm highlights FSC and PEFC chain of custody, factory finishing, and conservation expertise. (heronbros.com)

Competitive snapshot

Here is how this debut lands next to familiar names in timber windows and doors.

• VELFAC shows current wood window EPD coverage published with EPD International, which keeps them visible on European jobs that lean on that library.
• Rationel likewise lists product‑specific wood window EPDs with EPD International, aligning to EN 15804.
• NorDan publishes multiple windows and exterior door EPDs with EPD Norway, a common path for Nordic joinery.
• Several UK heritage specialists remain thin on current EPDs. For example, Mumford & Wood shows an expired entry in public data rather than a current product‑specific EPD.

Net, Heron has entered the transparency arena where established European window brands already play, while also gaining an edge in local matchups where current EPDs are still rare.

Program operator context

For buyers who ask who verified the declarations, Heron’s records sit with EPD Hub, a digital‑first EN 15804 program operator. If your projects prefer a particular operator library, the key is simple findability and clear scoping that mirrors the window or doorset being specified. (epd.guide)

What to do next

Two quick plays can turn new EPDs into spec wins. First, mirror the portfolio logic in sales content so estimators know which EPD covers casements, sliding sash variations, and the standard doorset builds. Second, add a central downloads or sustainability page that lists each EPD by product family with direct links, because submittal speed often decides who gets swapped in.

At the time of writing, we did not locate Heron Joinery’s EPDs on their website. Publishing them prominently will help design teams self‑serve during bid crunch and reduce back‑and‑forth on documentation. (heronjoinery.com)

Bottom line

Four targeted EPDs covering core timber windows and doors moves Heron Joinery from datasheets to decision‑ready. It narrows the gap with European players already publishing and positions their bespoke joinery for projects that filter by verified impacts. Keep the momentum by making those declarations easy to find and reflecting common options in the scoping text teams actually read.
