Eurotag Danmark A/S (Derbigum)

What Eurotag Danmark A/S (Derbigum) does

Derbigum Danmark A/S (formerly Eurotag Danmark A/S until April 2025) is the Danish sales and technical-support entity of the Derbigum roofing brand, wholly owned by Belgian manufacturer Imperbel SA. Headquartered in Brabrand, Midtjylland, with a team of approximately 7, the company markets a portfolio of APP- and SBS-modified bituminous roofing membranes, underlays, and liquid waterproofing products. Core technology includes dual-reinforcement membranes (glass fibre web plus polyester non-woven), proprietary "Derbitumen" recycled bitumen derived from production offcuts, construction-site waste and reclaimed old membranes, and the Novitumen technology — the market's first bituminous roofing membrane with zero virgin bitumen. The portfolio is organised into top membranes (Derbigum NT 4, Derbicolor NT, Derbigum GC, Derbigum GC AR, Residek 5000), underlays (Derbicoat NT 2.5, Derbicoat HP variants), and liquid products (Derbibond NT/S, Derbigum DMS).

The company runs a hybrid channel-based and direct-enterprise go-to-market: it sells exclusively through a network of trained, authorised roofing contractors (autoriserede tagdækkere) supported by an Extranet portal, while running direct technical-sales and free roof-condition-assessments (tilstandsvurdering) for building owners, property managers, and public-sector clients. Pricing is quote-based per project, with no public list pricing, and revenue is primarily project-driven hardware sales with recurring activity tied to renovation cycles. Demand generation is led by specifier-facing content: Lunch & Learn sessions, NBS Nordic and ProdLib BIM/Revit tooling, EPD/LCA documentation aligned to DGNB and BREEAM, a blog, YouTube channel, and a six-to-eight-times-yearly newsletter. Key customer segments include commercial and institutional building owners and property managers, professional roofing contractors, architects and specifiers, residential/multi-family developers, and parking-deck and infrastructure owners.

Derbigum differentiates on three documented pillars: 50+ year membrane service life independently certified by the British Board of Agrément (BBA 86/1593, with real-roof field evidence dating to 1973), circular-economy leadership via the No Roof To Waste closed-loop take-back programme and 25-100% recycled content, and a sustainability-documentation suite (EPDs, Cradle to Cradle Certified, DGNB/BREEAM-ready packages). Notable Danish reference projects include Copenhill/Amager Bakke (17,000 m², BIG), Holbæk Sportsby (23,000 m², Kullegaard), BaseCamp Skovbrynet (26,000 m², Lars Gitz Architects), Bygma Svendborg (DGNB Gold, 6,500 m²), Naviair at Copenhagen Airport (6,000 m²), and the Zootårnet restoration at Copenhagen Zoo (nominated for RENOVER Prisen 2022). The entity operates as a small but technically anchored Danish arm of a larger Belgian industrial group, with manufacturing economics and R&D residing at the parent.

Revenue model

1. Roof Membrane and System Product Sales: Derbigum Danmark generates the majority of its revenue from the sale of proprietary bituminous roofing membranes (top layers), underlays/damp-proof membranes, and bituminous liquid products. Products are sold to authorized roofing contractors who install them on behalf of building owners, developers, and property management companies. The portfolio includes Derbigum NT, Derbicolor NT, Derbigum GC, Derbicoat NT, and related liquid waterproofing and adhesive products. Revenue is primarily one-time per project (roof installation), but recurring revenue arises from renovation cycles and the service/maintenance ecosystem.
2. Technical Advisory and Inspection Services: Derbigum Danmark provides complementary technical consulting services to building owners, property managers, and public entities, including free roof condition assessments (tilstandsvurdering) and Lunch & Learn sessions for specifiers. These services drive product specification and reinforce brand loyalty, supporting hardware sales indirectly.

Core offering

Derbigum Danmark develops, manufactures, and sells bituminous roofing membranes and waterproofing systems for flat, green, white, visible, terrace, and parking-deck roofs. The portfolio includes top membranes (Derbigum NT, Derbicolor NT, Derbigum GC/GAR, Derbigum SP FR, Residek 5000), underlay/damp-proof membranes (Derbicoat NT, Derbicoat HP SELFIX, Derbicoat HP FM), and bituminous liquid products (Derbibond NT/S cold adhesives, Derbigum DMS). Products are made using proprietary Derbitumen recycled-bitumen technology and are sold exclusively through a network of authorized roofing contractors in Denmark.

Product overview

Derbigum offers a comprehensive portfolio of bituminous roofing and waterproofing solutions organized into three main product categories: top membranes (topmembraner), underlays/damp proof membranes (underpap og undertag), and bituminous liquid products (bituminøse flydende produkter). The NT (New Technology) series incorporates Derbitumen—recycled bitumen from production waste and demolished roofs—enabling circular economy principles with products containing 25-30% recycled content while maintaining full recyclability. Top membranes include DERBIGUM NT 4, DERBIGUM NT AR/FR, DERBIGUM SP FR, DERBICOLOR NT series (including PATCH and WSL variants), DERBIGUM GC (for parking decks), DERBIGUM GC AR (root-resistant), and RESIDEK 5000.
