What Klober does

Klober, legally BMI Deutschland GmbH, is a German manufacturer of pitched and flat roof components headquartered in Schwelm and operating since 1960. The company's portfolio spans roof ventilation products (Flavent, Flavent Pro, Venduct), vapour-permeable and other underlays (Permo), sealing and wrap systems (WrapTec, Trapac), and additional accessories including the Prismax line, with three production sites located in Germany supporting domestic manufacturing. Within its category, Klober self-positions as a leading provider of roof ventilation and exhaust products in the German market.

The business is operated as a subsidiary within the BMI Group, an international roofing conglomerate, which provides corporate scale, brand portfolio breadth and cross-border distribution reach, although the Klober brand is the primary identity for specialist trade partners in Germany. Distribution is deliberately channeled exclusively through specialist trade partners (Fachhandel) rather than direct-to-installer or direct-to-consumer channels, and the company maintains a regional field-sales structure with dedicated representatives covering defined German territories.

Commercial motion is supported by digital tooling for the trade channel, including the Klöber Finder product configurator and a Filecamp-based digital asset library, which assist specialist partners with product selection and specification. The company has no consumer-facing app, no public API surface, and no disclosed AI or machine-learning capabilities; the digital tools in evidence are configurator- and content-management in nature rather than data-driven recommendation systems. Public customer references (e.g., Gosch Restaurant, Städtische Sparkasse Schwelm) appear as project case studies, consistent with a long-tail, project-driven demand profile within the German roofing trade.

• SIGA: Swiss specialist in high-performance airtightness and roof/weather membranes. Overlaps with Klöber's Permo diffusion-open underlay and vapor-barrier business, particularly in energy-efficient and passive-house construction segments.
• Velux Group: Danish global leader in roof windows and skylights. Directly competes with Klöber's Prismax roof daylight/window line in both new-build and renovation markets, and shares the same specialist trade and installer customer base.
• Roto Frank: German-headquartered manufacturer of roof windows and skylights. Directly comparable to Klöber's Prismax product line, serving the same German and European specialist trade and roofing contractor customers.
• Dörken GmbH & Co. KG: German manufacturer of high-performance building protection membranes, including the DELTA roof underlay and air-tightness lines. Directly competes with Klöber's Permo underlayment and vapor-barrier membranes for German specialist trade and roofers.

Others

• Monier (BMI Group brand): Sibling BMI Group brand focused on pitched-roof tiles and integrated roofing systems across Europe. Operates within the same parent group as Klöber and competes for shared specialist trade and installer relationships in overlapping German and European markets.
