What Air Lux Technology does
Air-Lux Technik AG (operating as air-lux) is a Swiss custom manufacturer of large-scale frameless glass facade elements built around a patented pneumatic air-sealing technology. Founded in 2004 as an innovation within parent Krapf AG (itself established in 1964), the company designs and produces sliding windows, descending windows that retract into the floor, and pivot doors for luxury private residences, commercial high-rise buildings, and architectural special solutions. The core technology uses air pressure to inflate ring gaskets integrated into thermally separated aluminum profiles, delivering 100% airtightness against rain, wind, and noise throughout the product lifecycle while accommodating up to 1800 kg panels and building movements of 40 mm floor settlement and 20 mm base settlement.
The company operates a project-based, custom-manufacturing business model. All products are made to order at the Engelburg/SG headquarters in Switzerland, with pricing quoted per project rather than publicly listed. Revenue is generated primarily through one-time sales of customized window and door systems, supplemented by an after-sales service stream offering maintenance, replacement parts, and extended warranties on a 10-year base frame, fittings, and seal warranty. Distribution combines direct enterprise field sales in Switzerland and Germany with a network of vetted international distribution partners across 12 countries, supported by showrooms in Prague and Frankfurt and an architect-focused marketing approach via trade fairs (BAU Munich, Architect@Work), design awards, and technical documentation.
Air-Lux Technik AG is a privately held Swiss Aktiengesellschaft and a subsidiary of family-founded Krapf AG. Since 2021, Lukas Knechtle has served as both CEO and owner, leading a management team of approximately 80 employees. The company has completed over 500 projects worldwide, holds patents and trademarks across Switzerland, Europe, USA, and China, and maintains certifications including ISO 9001, IFT Rosenheim, Minergie, RC2/RC3 burglar resistance, NAMI (US), and US hurricane test approval. A 2020 strategic partnership with Schüco and the 2024 launch of the air-lux academy underscore ongoing ecosystem and capability investment.
