What SOPREMA UK does

SOPREMA UK manufactures and supplies building envelope solutions — waterproofing, thermal insulation, and soundproofing systems — for the UK construction market. Its core product portfolio spans bituminous membranes (formerly Chesterfelt), synthetic TPO and PVC geomembranes (FLAGON), PMMA liquid waterproofing (ALSAN), hot-melt structural waterproofing (DUOFLEX), PIR insulation (formerly Celotex), multifoil insulation (formerly YBS), extruded polystyrene (SOPRAXPS), natural wood-fibre insulation (PAVATEX), and acoustic insulation (TECSOUND). The company also offers integrated smart solutions covering cool roofs, solar roofs, green roofs, roof terraces, and soundproofing, and serves civil engineering applications including bridge deck waterproofing and underground works. SOPREMA UK is a wholly-owned subsidiary of France-based SOPREMA Group (founded 1908, present in 90+ countries); in 2024 the UK business unified its previously separate Celotex, YBS Insulation, and Chesterfelt brand identities under the single SOPREMA UK banner.

The company operates a specification-led, enterprise field-sales GTM targeting architects, specifiers, main contractors (e.g., Vinci, Mulalley, Roofline Group), and developers during the building design phase. Sales motion is supported by technical services — CAD designs, U-value and WUFI calculations, BIM objects via the NBS National BIM Library, tapered design, drone surveys with thermal imaging, and RIBA-accredited CPD training — alongside a CITB-accredited training facility. Products flow to end users through merchant/distributor channels and an approved-contractor network, with public-sector revenue enabled by framework approvals (B2G FR22, Procure21, Constructionline Materials Plus/Premier, RISQS for rail). Revenue is generated primarily through one-time sales of building materials, complemented by technical-services and training revenue streams. SOPREMA UK holds 36 product-specific Environmental Product Declarations, ISO 9001/14001/45001 certifications, BBA product certifications, FM Approved roofing systems, and PAS 2060 operational carbon neutrality (Scope 1, 2, operational Scope 3).

Customer evidence is distributed across healthcare (Chase Farm Hospital, Addenbrooke), sports infrastructure (Wembley Stadium, Ferrari World Abu Dhabi), transport (Thames Cable Car), social housing (Isle of Dogs blocks via Mulalley), education (Windsor Olympus Academy), and residential developments (Canada Gardens, Sugar House Island, MU4 and Aire Park in Leeds). Pricing is quote-based and not publicly disclosed; warranty programs and 20-year single-point warranties form part of the offer. Headcount data for the UK entity specifically is not stated in the source material; the consolidated entity operates from SOPREMA House, Witham, Essex.
