Ströher: products and EPD coverage at a glance

Who Ströher is and where they play

Ströher is a German ceramics manufacturer focused on extruded clinker brick slips, outdoor terrace tiles, garden slabs, stair systems, and residential wall and floor tiles. Their portfolio targets ventilated façades, balconies and terraces, high‑traffic stairs, and residential interiors. The company positions its materials for energy‑efficient building envelopes and durable outdoor applications.

Product portfolio in plain English

The range spans four primary categories on the site: clinker brick slips, terrace tiles, garden slabs, and home ceramics. Within those, there are dozens of series and colorways that add up to hundreds of SKUs across formats, trims, and stair elements. Think of it like a Lego bucket for specifiers, with corner pieces and stair treads that help details come together cleanly.

What EPDs exist today

Ströher hosts two association EPDs for ceramic tiles that are valid from 2022 to 2027 and verified by IBU under EN 15804, one aligned to A1 and one to A2. These are industry‑wide declarations published for Bundesverband Keramische Fliesen e.V., not product‑specific to individual Ströher series (IBU EPD BKF 20220183 and 20220184, 2022). Most construction EPDs carry a five‑year validity window set at verification, with mid‑cycle updates if results change materially (EPD International, 2025).

Why this matters for specs

Industry‑wide EPDs lower friction in general tile specs, yet many project teams prefer product‑specific or at least manufacturer‑specific EPDs when alternatives offer them. LEED v5 was ratified by USGBC members on March 28, 2025 and continues to organize materials credits around transparent, third‑party data. Teams expect clean A2‑aligned documentation and easy calculator hand‑offs (USGBC, 2025). IBU ended new A1 processing after October 2022, so new or renewed German‑market EPD work should be A2 only to avoid comparability headaches (IBU, 2025).

Coverage strengths and gaps

Strength: the association EPDs give broad coverage for ceramic tiles, including extruded formats, and are valid through 2027 (IBU EPD BKF 20220183 and 20220184, 2022). Gap: we did not find Ströher product‑specific EPD PDFs for flagship series like clinker brick slips or outdoor stair systems on the public downloads page. Where tenders or owner policies ask for product‑ or plant‑specific results, this can push buyers toward alternatives that tick that box with less back‑and‑forth.

A likely bestseller lens

Clinker brick slips and matching corners are a signature Ströher use case on ventilated façades. If a bid requires product‑specific EPDs under EN 15804+A2, competitors can look stronger on paper. For example, Mosa publishes product‑specific tile EPDs for wall and floor ranges that specifiers can download directly (Mosa, 2024). Terracotta façade systems like Wienerberger’s Argeton reference EPD‑backed panels across their offer, which keeps façade packages documentation‑ready for submittals (Argeton, 2025). That is often all it takes for a spec to swing early in the decision process.

Competitors you will often meet

Expect to see Deutsche Steinzeug brands in pools, façades, and interiors, Mosa in premium architectural tiles, and Wienerberger Argeton on terracotta façades. Brick‑slip alternatives from groups like Vandersanden also appear in façade value engineering. The overlap is not one‑to‑one in manufacturing methods, yet it is close enough in application that EPD readiness becomes the tiebreaker.

What great looks like next

If a product‑specific EPD is on the roadmap, pick the series that drives the most bid requests and cover the related trims and corners in the same study. Align to EN 15804+A2, check your PCR version against the current transition notes so you are not surprised mid‑project, and plan renewal timing six to nine months before the printed validity date so sales never stalls (EPD International, 2025). The heavy lift is data collection. Teams that make it effortless for operations and R&D tend to publish faster and with fewer comments, which is definately noticed by specifiers.

Tie‑off

Ströher has breadth, proven outdoor durability, and association EPDs that carry them through 2027. Converting one or two high‑volume façade or stair systems into product‑specific A2 EPDs would turn a strong portfolio into an easy yes in LEED‑v5‑oriented specs and owner policies. That small move changes the conversation from can we use it to when can we install it.
