Troostwijk Auctions is liquidating the entire Eyrise B.V. liquid crystal glass production facility in Veldhoven, marking Merck's exit from the architectural smart glass business. The sale signals a sobering reset for dynamic glazing—and a rare opportunity for buyers willing to bet on switchable facades.
A Purpose-Built Smart Glass Factory Heads to the Auction Block
One of Europe's most advanced switchable glazing facilities is being parted out. Troostwijk Auctions has launched the sale of the complete production facility of Eyrise B.V. / Merck Windows Technologies B.V., a liquid crystal glass factory located in Veldhoven, the Netherlands. The plant was purpose-built to industrialize liquid crystal window technology—glass that switches between clear and opaque states in roughly one second, far faster than conventional electrochromic systems.
For architects and facade consultants who have specified Eyrise on signature projects—including the Niemeyer Sphere in Leipzig and BAFTA's London headquarters—the auction is a significant turn. Merck's former owner divested the facility to a trader in 2025, who is now auctioning it off, and Merck has confirmed it will no longer produce the glazing end products previously manufactured under the Eyrise brand.
Why This Matters for the Dynamic Glazing Market
Liquid crystal glazing has been one of the few credible alternatives to electrochromic smart glass for commercial facades. Eyrise was developed as a subsidiary of Merck and was positioned as setting an unprecedented standard for the use of liquid crystals combined with glass in the architecture and construction industry. Its key technical advantages over EC glass were color neutrality (no blue tint during darkening) and a switching time measured in about a second rather than minutes.
The exit of a deep-pocketed materials science company from this niche raises hard questions for specifiers:
- Specification risk: Projects in design or under warranty that rely on Eyrise IGUs now face uncertainty around long-term supply, replacement units, and service life support.
- Competitive landscape: Electrochromic suppliers (View, SageGlass) and PDLC/SPD providers gain market share by default, but the lack of a fast-switching, color-neutral LC competitor narrows the palette of dynamic options for facade designers.
- Capital intensity: The auction underscores how brutally expensive it is to industrialize a new architectural glass category. Even a parent like Merck, with decades of liquid crystal expertise from the display industry, could not sustain the unit economics.
The Auction Itself: A Turnkey Smart Glass Plant
The sale is unusually comprehensive. The auction includes advanced coating, lamination and processing equipment, testing installations, cleanroom environments and supporting technical infrastructure. According to Troostwijk, complete liquid crystal glass production facilities rarely come to market, particularly in such a modern and comprehensive configuration. The factory was only operational for a limited number of years and is being offered largely complete, with a 3D virtual tour available for prospective buyers.
For manufacturers active in architectural glass, facade systems, automotive glazing or high-tech materials, the auction presents a chance to enter or expand within the smart glass segment without the long lead times and capital expenditure typically required to develop a facility from scratch. International interest from strategic buyers and investors is anticipated.
Practical Implications for Architects, Specifiers, and Contractors
For architects with active LC glazing specs:
- Confirm warranty assignment and replacement-unit availability with your distributor before substantial completion.
- Review CD-stage specifications that reference Eyrise as a basis-of-design product. "Or equal" language may need revision since there is currently no direct one-for-one substitute for fast-switching, color-neutral LC glazing.
For glazing contractors:
- Audit pending submittals for Eyrise IGUs. Long-lead orders placed against the existing Veldhoven facility should be confirmed in writing.
- Expect lead-time and pricing volatility on dynamic glazing across the board as the supply base reshuffles.
For building product manufacturers and investors:
- A buyer that acquires the line could either restart Eyrise-branded production under license or repurpose the cleanroom and lamination equipment for adjacent applications. Either outcome will reshape competitive dynamics in switchable glazing over the next 18–24 months.
- The story is also a cautionary data point for VC-backed dynamic glazing entrants: scaling architectural smart glass requires patient capital and a project pipeline that current commercial real estate conditions are not generously providing.
The Bigger Picture
Smart glass has been pitched for two decades as the future of high-performance facades. The Eyrise auction is a reminder that even strong technology and prestige reference projects do not guarantee a sustainable manufacturing business. Specifiers who want dynamic glazing in their next project should pressure-test the financial durability of their suppliers as carefully as they evaluate U-factors and SHGC.
