What Riwega does
Riwega S.r.l. is an Italian privately held building-materials producer and distributor founded on June 1, 1998 in Egna (Bolzano), South Tyrol, operating with 51-100 employees. The company specializes in comprehensive building-envelope solutions for roofs and walls, organized across four sub-brands: eternitycomfort (ventilation, waterproofing, airtightness membranes, tapes, and sealants), planus (flat and green roof systems including T-PE membranes and protective felts), safetymania (fall protection — anchor points, lifelines, guardrails, PPE), and redbau (temporary construction-site safety — scaffolding, containers, lifting equipment).
The product portfolio is built around certified physical materials: breathable and hygrometry-variable membranes, fire-resistant membranes certified to Class B-s1,d0 and A2-s1,d0, radon gas-certified vapor barriers, single-layer T-PE waterproofing membranes with BROOF(t2) ratings, and modular fall-protection systems including photovoltaic-rooftop-specific anchor points. Differentiated offerings include the FDB Vario Corner FL (pre-folded variable-humidity tape with no liner), USB Classic 220 Green (bio-based functional film), and accessories such as Rainflex 100 (reusable rainwater drainage). Riwega also publishes extensive technical documentation — manuals for flat/green roofs and Tetto/Parete (roof/wall) systems, CAD drawings, specifications, and software — produced partly through a partnership with the ERGE Group.
Riwega's business model is B2B and sales-led: a dedicated Italian sales network (Rete Vendita) sells to professional installers (roofers, carpenters, metal workers, masons), architects, and engineers, complemented by an e-commerce storefront (store.riwega.com) supporting five languages. The company holds memberships in 17+ industry associations (ANIT, ASSIMP, ARCA, IFD Dachdecker, nZEB Partners, Klima Haus, Gebaudehulle Swiss, etc.) and operates a Technical Consultant extranet portal. No external funding rounds, acquisitions, or divestitures have been disclosed. Revenue is not publicly reported; share capital is the Italian statutory minimum of EUR 26,000.
