Sionic Smart Glass

What Sionic Smart Glass does

Sionic Smart Glass GmbH is a Dortmund, Germany-based high-tech startup that develops and manufactures micro-optically integrated smart glass films and insulating glass units (IGUs) marketed under the ClimaVision® brand. Its core technology combines vacuum coating, wet coating, UV/IR curing and nanoimprint lithography in ISO-5 cleanroom roll-to-roll processes to produce multilayer functional films on PET substrates up to 1.5 m wide, supporting IR/UV blockers, conductive, microstructured, nanoparticle-based, thermally adaptive and electro-optical layers. The portfolio is split across Functional Films for retrofit (sun protection, thermal insulation, micro-louver, switchable privacy) and factory-integrated IGUs (heat and solar control glass, integrated micro-louvers, adaptive solar control, switchable privacy, switchable solar control).

The company's commercial model is built on quote-based, project-driven B2B sales with multi-year contracts. Revenue streams combine one-time film sales for retrofit, hardware sales of factory-integrated IGUs to glass manufacturers and building projects, and professional services through the company's own installation team. Go-to-market is hybrid: direct consultative sales to commercial, public and private building owners, supplemented by channel partnerships with insulating glass manufacturers and film application companies, plus an in-house installation capability. Marketing is conducted through company website content, LinkedIn, trade fairs (Fensterbau Frontale, Expo Real, BAU), free energy-analysis consultations, downloadable product literature and a quarterly newsletter.

Sionic targets four customer segments — commercial real estate (primary), public/institutional buildings, private residential buildings with large glass surfaces, and listed heritage buildings where non-invasive retrofit is required. The customer value proposition centres on energy-efficient renovation that avoids full window replacement (claimed up to 70% cost savings), with quantified performance including up to 72.3% solar energy input reduction (adaptive film at 80°C), up to 63.4% with CC-35 sun protection film, up to 28.8% heat-loss reduction with low-e films, and U-values up to 0.5 W/m²K in ClimaVision IGU configurations. Three product launches are scheduled across 2026 (ClimaVision® private IGU Q2 2026; ClimaVision® adaptive and ClimaVision® smart Q4 2026) and a new electrochromic production line is being established at the Dortmund Technology Park site.

Core offering

Sionic Smart Glass develops, manufactures, and sells micro-optical functional films and integrated insulating glass units under the ClimaVision brand for intelligent control of natural sunlight and daylight in building windows and glass facades. The product range covers retrofittable films (sun protection, thermal insulation, micro-louver, switchable privacy) and factory-integrated glass units (heat and solar control, micro-louver glass, adaptive solar control, switchable privacy, switchable solar control). All products are produced via roll-to-roll technology in ISO-5 cleanrooms and are sold primarily to commercial, public, and private building owners for energy-efficient window renovation.

Product overview

Sionic Smart Glass offers a portfolio of micro-optically integrated functional films and insulating glass units under the ClimaVision® brand for intelligent control of natural sunlight and daylight in windows and glass facades. The product line comprises two categories: Functional Films (retrofittable sun protection films, thermal insulation films, micro-louver films, and switchable privacy films) and Insulating Glass Units (heat and solar control glass, glass with integrated micro-louvers, adaptive solar control glass, switchable privacy glass, and switchable solar control glass). All products are manufactured using roll-to-roll technology in ISO-5 clean room conditions and address four key challenges: sun protection, thermal insulation, privacy, and energy-efficient renovation.

Products and services

• ClimaVision® cool (Sun Protection Films) Nanometer-thin exterior coatings that block and reflect UV and infrared radiation, reducing visible sunlight to specified intensity for pleasant lighting conditions and high thermal protection. Reduces solar energy input by 19.7% to 63.4% depending on variant. For commercial and private building owners retrofitting existing glass facades.
• ClimaVision® low-e (Thermal Insulation Films) Retrofittable interior low-e films for older existing buildings that reflect heat radiation back into the room, reducing heat loss and lowering heating costs. Available in CL-1 and CL-2 variants with different g-values. Up to 28.8% reduction in heat loss. For energy-efficient renovation of older buildings.
• ClimaVision® micro (Micro-Louver Films) Static microstructured films with horizontal or slightly inclined lamellas that regulate light passively and angle-dependently, blocking direct sunlight while allowing diffuse daylight. Self-regulating response to sun position without moving parts. For glare and heat protection in commercial and residential buildings.
• ClimaVision® private (Switchable Privacy Films) Electrochromic smart glass films that switch between clear and opaque states in seconds, providing instant privacy control at the touch of a button without sacrificing natural daylight. Integrated within insulating glass units or laminated safety glass. For workspaces, conference rooms, and private living areas.
• ClimaVision® core (Heat and Solar Control Glass) Insulating glass units combining integrated thermal insulation films with location- and orientation-optimized sun protection. Achieves performance values of modern triple glazing with 33% less glass, lower weight, and reduced CO2 footprint. U-values up to 0.5 W/m²K. For new builds and renovation projects.
• ClimaVision® micro (Glass with Integrated Micro-Louvers) Insulating glass with integrated micro-louver film where static micro-louvers allow diffuse daylight while shielding from direct sunlight. Self-regulating angle-dependent transmission reacts to sun position for maintenance-free solar control. For glass facades in new builds and renovations.
• ClimaVision® adaptive (Adaptive Solar Control Glass) Adaptive insulating glass with thermally adaptive film that reacts independently to rising outside temperatures, automatically adjusting light and energy transmittance to reduce solar gain. Passive, maintenance-free operation with no control technology required. Market launch scheduled for Q4 2026. For new builds and renovations.
• ClimaVision® private (Switchable Privacy Glass) Switchable privacy glass with integrated smart glass film that changes from clear to opaque in seconds. Available as IGU for outdoor applications (windows and facades) or laminated safety glass for indoor partition walls and meeting rooms. Market launch scheduled for Q2 2026.
• ClimaVision® smart (Switchable Solar Control Glass) Switchable solar control glass that controls light incidence and solar heat gain at the touch of a button. Transparency adjustable continuously or in defined increments between clear and darkened settings. Integrable into modern building and app control systems. Market launch scheduled for Q4 2026.
