EILENBURGER FENSTERTECHNIK GMBH & CO. KG

Their core work

Eilenburger Fenstertechnik is a German window manufacturing SME that develops and produces technically advanced window systems for the construction sector. Their work goes beyond standard glazing — they have demonstrated capability in large-area fluid-based window technologies (fluidic windows for energy management) and in developing soundproof windows with integrated ventilation functions. They bring real industrial manufacturing expertise to research consortia, converting laboratory concepts into buildable window products. Their niche sits at the intersection of building physics, acoustic engineering, and energy-efficient facade design.

What they specialise in

How they've shifted over time

In their first project (2015–2017), Eilenburger participated in LaWin, focused squarely on material development and building envelope technology — the role of an industrial partner bringing manufacturing know-how to a research-led initiative. By 2017–2019, they had moved to coordinating soundproof4win under the SME Instrument Phase 2, a highly competitive funding scheme reserved for commercially ready innovations — signalling a shift from technology exploration toward product commercialization. The trajectory is clear: they progressed from component contributor to project leader, and from fundamental materials research to integrated product development with a defined market application (noise reduction + ventilation in windows).

They are moving up the value chain — from R&D participant toward market-facing product developer and consortium leader — suggesting future collaborations would likely be industry-driven, close-to-market projects rather than basic research partnerships.

How they like to work

Eilenburger has demonstrated both partnership and leadership roles across their two projects, which is notable for a small SME. In LaWin they acted as an industrial participant within a larger consortium, while in soundproof4win they took the coordinator seat on an SME Instrument Phase 2 project — a role requiring strong project management and commercialization planning. With 13 unique partners across 4 countries over just 2 projects, they appear to work with moderately sized, diverse consortia rather than tight repeated partnerships.

Eilenburger has collaborated with 13 unique partners across 4 countries, a respectable network spread for an SME with only 2 projects. Their geographic reach is European, with a likely concentration in DACH and neighbouring construction-sector economies given their German industrial base.

What sets them apart

Eilenburger is rare among H2020 SMEs in that they are an actual window manufacturer — not a research institute or consultancy — who has successfully led an SME Instrument Phase 2 project, the most commercially rigorous EU funding scheme. This means they combine hands-on production capability with validated ability to manage EU-funded innovation projects end-to-end. For consortium builders in construction, facades, or building physics, they offer a direct route from prototype to manufacturable product in the window and glazing segment.

Highlights from their portfolio

• soundproof4win
  Coordinated as SME Instrument Phase 2 — the EU's most competitive near-market funding scheme — receiving EUR 1,050,875 to commercialize a soundproof window with integrated ventilation, demonstrating both technical ambition and strong business case validation by EU evaluators.
• LaWin
  Participation in a large-area fluidic window project places Eilenburger among early industrial actors exploring dynamic, fluid-based glazing — a technology with significant implications for building energy management.
