Altana

What Altana does

Altana is a Danish balcony specialist company founded in 2013, headquartered in Ringsted, Denmark, and operating as a wholly-owned subsidiary of Swedish listed facade conglomerate Fasadgruppen Group AB (Nasdaq Stockholm) since July 2022. The company designs, engineers, manufactures, and installs balconies for older residential buildings, producing its products at its own Ringsted facility and offering facade, French, Spanish, mansard, roof, and staircase-entrance balcony types in steel, aluminum, concrete, and fiber concrete. The company's core technology stack centers on multi-material production and four mounting techniques (direct wall insertion, tension rod anchoring, floor exchange, and column-based support) adapted to building structure and permit constraints.

Altana serves a single primary customer segment: Danish housing associations (boligforeninger) and residential cooperatives, primarily in the Copenhagen metropolitan area, with additional services for individual property owners and administrators. Its business model is one-time project-based installation revenue, priced per balcony (typically 100,000-170,000 DKK for facade units; 30,000-300,000 DKK across the full product range), with quotes driven by balcony type, material, size, mounting method, and crane requirements. Altana differentiates through end-to-end project management covering municipal permits, engineering calculations, production, and installation, eliminating the need for housing associations to coordinate multiple contractors. Distribution is delivered through field sales consultants conducting on-site property visits, supported by content marketing (blog, whitepaper), Trustpilot reputation, and neighborhood referral visibility from completed projects. The company has earned five consecutive Børsen Gazelle awards (2019-2023), Great Place to Work 2023 certification, and AAA creditworthiness, positioning it as a recognized Danish market leader backed by the Nordic region's largest facade group.
