What Bauder does

Bauder Ltd is a UK-headquartered private manufacturer of flat roof waterproofing, insulation, green roof, blue roof, and integrated photovoltaic systems, established in 1857 and operating from Ipswich with a warehouse in Stowmarket, a regional office in Dublin, and a new manufacturing facility in Drusenheim, France opened in June 2026. The core technology portfolio spans four waterproofing platforms — reinforced bitumen membranes (BTRS PLUS, BTRS, Bauderflex, Airtech), single ply membranes (Thermofol PVC, Thermoplan FPO), cold-applied liquids (LiquiTOP PU, LiquiTEC PMMA), and Bakor hot melt systems — complemented by BauderPIR, BauderGLAS, BauderJFRI, BauderVIP, and BauderECO FF insulation products, plus BauderGREEN extensive/intensive/biodiverse roof systems, BauderBLUE stormwater attenuation, and BauderSOLAR PV mounting. Products are sold exclusively through a national approved-contractor network in the UK and Ireland, with sales supported by free technical services including roof surveys, moisture mapping, thermal and condensation analysis, wind load calculations, BIM objects, NBS Chorus specifications, and on-site installation monitoring.

Revenue is generated primarily through hardware sales of roofing systems channelled via approved contractors, supplemented by free technical specification and survey services that function as a pre-sales differentiator rather than a standalone billable line. Bauder holds CCPI-assessed product information across its core waterproofing portfolio, BBA certifications with BROOF(t4) fire classification and verified service life exceeding 35 years, FM approval on mechanically fastened single ply systems, EPD certifications, and compliance with UK Building Regulations Part B and Part H. The business model is consultative and specification-driven, targeting architects, building designers, surveyors, facilities managers, and building owners across education, healthcare, heritage, government, and commercial sectors; key reference projects include Jodrell Bank Discovery Centre, Lloyd's Building, Royal Marsden Hospital, Halifax Bus Station, JCB World Headquarters, and Camden Council social housing stock.
