Binné & Sohn.

What Binné & Sohn. does

Binné & Sohn GmbH & Co. KG Dachbaustoffwerk is a German manufacturer specializing in flat roof waterproofing, thermal insulation, and green roof systems, headquartered in Pinneberg, Schleswig-Holstein. Founded in 1879 as a drugstore and transitioned to roofing materials manufacturing in 1894, Binné is now a sixth-generation family business operating as part of SOPREMA GmbH following its February 2, 2026 acquisition. The company's core products are bitumen and polymer-modified bitumen waterproofing membranes manufactured in-house at the Pinneberg facility under the BISOTEKT and DURITHERM brands, complemented by expanded polystyrene (EPS) thermal insulation under DURIPOR, complete green roof systems under BISOFLOR (films, drainage elements, substrates, vegetation, anchoring mats), and building waterproofing membranes under DURITHENE. Notable proprietary technology includes the NOxOFF photocatalytic coating that converts nitrogen oxides into harmless nitrates via UV activation, and vacuum insulation panels achieving 0.007 W/(mK) thermal conductivity. The company produces millions of square meters of membranes annually and is DIN EN ISO 50001:2018 energy management certified.

The company monetizes exclusively through hardware sales to professional B2B buyers across the German construction value chain — primarily roofing contractors (Dachdecker), architects and planning offices, general building contractors, and building material dealers — using a hybrid direct sales model combining regional field sales representatives (Fachberater) covering Germany, an internal sales team at headquarters, a dedicated slope-planning (Gefälledachplanung) service, and on-site application support via Lehrverleger supervisors. Pricing is quote-based and not publicly disclosed, with standard terms offering 2% discount for payment within 8 days versus a 30-day net period. Distribution is augmented by the Kluth Dachbaustoffe subsidiary in Barsinghausen, acquired in 2018, which extends the range to aluminum roof edge profiles. Following the SOPREMA acquisition, regional customer contacts and Scandinavian operations were consolidated into the parent group's broader footprint, while the Pinneberg facility remains operationally active under continued family stewardship at the site level.
