Seduna AB

What Seduna AB does

Seduna AB is a Swedish private limited company founded in 2017 and headquartered in Alvesta, Sweden, operating as a subsidiary of Norwegian parent Bergknapp Holding AS. The company designs, supplies, and installs green and blue-green roof and vegetation systems adapted to Nordic climate conditions, serving architects, contractors, and property owners with project engineering, system selection, load calculations, and structural proposals from early design through execution. Its core technology platform is the Seduna Roof System (SRS), offered in four slope-banded variants (1-27°, 1-3°, 0-15°, and Sedumkassett 1-7°) to cover flat, low-slope, and steep roofs, supplemented by a Bjälklag floor-structure system for courtyards and rooftop terraces, green facades via the Seduna Green Wire (SGW), and a full component range including drainage mats (SDB 10/12), water-retaining filters (SMB 40), and root barriers (SRB 50).

The product portfolio includes pre-cultivated sedum mats, sedum cassettes, plant cassettes, meadow mats, perennial mats, and forest mats, with vertical solar cells as an add-on. Seduna monetizes through project-based quotations covering both complete systems with installation and material-only packages for contractor self-installation, plus recurring annual maintenance service agreements. Pricing is quote-based per project with no public list, reflecting project-specific scope and customization. Distribution is direct via an in-house project engineering team, an installation crew, and a network of collaboration partners covering all of Sweden, with regional sales coverage in Stockholm and Malmö. The company is privately held, with no disclosed revenue or funding rounds, and operates within the parent Bergknapp group structure that provides Nordic production capacity and over 20 years of vegetation system expertise.

Direct peers

• Veg Tech: Swedish competitor specializing in green roof mats, vegetation systems, and associated substrates. Operates in the same Swedish market with comparable sedum-based product offerings, directly contesting Seduna's specification-driven sales channel with architects and contractors.
• Bergknapp Holding AS: Seduna's Norwegian parent company and the originating Nordic producer of sedum and vegetation systems with 20+ years of experience. Operates the same core product platform and serves overlapping Nordic markets, making it both owner and most directly comparable peer.

Broad incumbents

• Bauder: European manufacturer of flat roof waterproofing and green roof systems with established product lines for sedum, extensive, and intensive green roofs. Overlaps with Seduna on full-system supply and competes on specification for commercial and municipal projects.
• ZinCo: Established German-headquartered international provider of green roof systems, including root barriers, drainage layers, and engineered substrate solutions. Overlaps directly with Seduna's full-system offer and competes for specification on larger Nordic and European projects.
• Xero Flor: Internationally distributed pre-vegetated sedum mat and green roof system provider. Comparable to Seduna on product type (pre-grown sedum mats and cassettes) and target customer base (architects, contractors, building owners), though at much broader geographic scale.
• Sempergreen: Netherlands-based international supplier of sedum mats, cassettes, and green facade systems. Direct product overlap with Seduna across sedum mats, cassettes, and vertical greening, including climate-adapted variants suited to Northern European conditions.
• LiveRoof: US-based modular green roof system provider using pre-vegetated modules comparable to Seduna's Sedumkassetter line. Targets similar building owner, architect, and contractor customers via a project-driven distribution model, though primarily in North America.
• Optigrün: German specialist in extensive and intensive green roof systems, drainage, and vegetation solutions with a long-established specification channel. Comparable to Seduna on system-engineering depth and on serving architects and roofing contractors across Europe.
