Milgard Windows & Doors: EPD readiness check
Milgard is a West Coast mainstay for residential windows and patio doors. If you sell into projects where product transparency sways specs, this snapshot shows what they make, how broad the line is, and where Environmental Product Declarations could move the needle.
Who Milgard is and what they sell
Milgard builds residential windows and patio doors under familiar series like V400 Tuscany, V300 Trinsic, V250 Style Line and C650 Ultra fiberglass. They also market large-format AX moving glass wall systems for indoor to outdoor transitions. The portfolio spans several material families and, by configuration and size options, runs to dozens if not hundreds of SKUs.
Product range breadth
Across vinyl and fiberglass windows you will find single and double hung, sliders, casement, awning and picture units, plus sliding and hinged patio doors. The AX moving glass walls add higher-ticket openings for premium remodel and new-build applications. This makes Milgard a multi-category player rather than a pure play in a single frame material.
What we could verify on EPDs today
As of November 27, 2025, we could not locate publicly available product-specific Type III EPDs for Milgard-branded windows or doors. Milgard’s own guidance focuses on ENERGY STAR and how products can contribute to LEED without pointing to EPD documents, which usually appear on a sustainability or certifications page (Milgard Green Building Practices). If you have a private declaration or pilot in progress, publish it visibly so specifiers actually count it.
Why that gap matters on bids
LEED projects count product-specific Type III EPDs toward materials credits, so a missing EPD can force teams to use conservative default factors that penalize selection. LEED v5 was ratified by USGBC members in March 2025 and continues to emphasize product transparency pathways that reward declared products (USGBC, 2025). On owner-driven standards and corporate procurement lists, EPDs increasingly act like a hall pass.
Likely best sellers that deserve fast EPD coverage
Milgard’s V400 Tuscany and V300 Trinsic windows show up frequently in dealer catalogs and distributor assortments. Publishing family EPDs that cover common operator types and glass packages would let sales teams walk into LEED-aimed multifamily jobs with confidence. Start with the highest-volume sizes and a cradle to gate scope, then extend variants as data maturity improves.
Competitors are publishing
Andersen announced three new EPDs in November 2025 that cover 14 non‑coastal window products across the 100, 400 and A‑Series lines, which are direct substitutes in many residential specs (Andersen, 2025). In Europe, JELD‑WEN subsidiaries have registered multiple door EPDs, another signal that mainstream fenestration brands treat declarations as table stakes in regulated markets (EPD Hub, 2024–2025). If a spec calls for product-specific EPDs, a Milgard unit without one can be swapped for a listed Andersen model in seconds.
The fast path to a credible Milgard EPD set
Pick the right rulebook. NSF 1102‑23 is the updated Part B PCR for Fenestration Assemblies and is designed for window EPDs in North America (NSF, 2024). Scope your phase plan around the biggest volume families first, define one to two glass packages per series, and model representative sizes to keep verification efficient. Line up primary data from a reference year for key plants, and use glass supplier EPDs to speed inventory quality. The result is a tight, defensible family EPD that specifiers will actually use.
Commercial upside for sales, not just compliance
When declarations exist, reps stop dodging projects that ask for them and start leaning in. EPDs reduce substitution risk and keep you from competing only on price. One mid-sized multifamily award can repay the effort quickly, even if EPD work feels like a lift up front. It’s definately easier when your LCA partner drives data collection and project management instead of handing you a spreadsheet and wishing you luck.
Where Milgard plays and who they meet in the market
Expect head‑to‑head moments with Andersen, Pella, Marvin and JELD‑WEN in residential replacement and new construction. In coastal or large opening packages, moving glass walls may also square off against specialty systems from premium brands. For schools, healthcare and multifamily, published EPDs are increasingly a screening line item rather than a nice‑to‑have.
Wrap up
Milgard has a broad, spec‑relevant lineup across vinyl and fiberglass windows, patio doors and moving glass walls. The missing piece is visible, product‑specific EPDs. Prioritize the V400 and V300 families, use NSF 1102‑23, and publish where architects actually look. That single move can turn more shortlist appearances into wins.

Frequently Asked Questions
Why would a family EPD help when Milgard sells so many sizes and configurations?
Family EPDs let you cover a set of closely related products under one verified declaration when modeled correctly. That means your common operator types and glass packages contribute to LEED without requiring a separate EPD for each SKU.
Do glass supplier EPDs reduce our workload?
Yes. Verified flat and processed glass EPDs provide high‑quality background data for the bill of materials. That speeds modeling and strengthens the declaration, especially when combined with primary plant data.
What scope should we publish first?
Cradle to gate is the fastest credible start for windows in North America. You can extend to use stage modules later as data and customer requests warrant.
