What SPS Envirowall does

SPS Envirowall is a UK-based specialist supplier of external wall insulation (EWI) systems, rainscreen cladding, building boards, and complementary facade components, operating as a trading name of Benx Ltd. (parent group Benx, founded 1990). Its product portfolio spans certified EWI systems (Wall System 1, Wall System 2, Cavity Systems 1 & 2, Direct Fix, TS Rail) covering masonry, timber frame, and steel frame substrates; facade panels (Supertech Weatherboard, Rockpanel, Swisspearl, Alucobond, Luxe Coat, RendaClad, Slipfast); A1/A2 fire-rated building boards (Y-Wall, Densglass, Multipurpose, Cemboard, Renderflex); and a components range including reinforcement mesh, cavity barriers, airtightness, fixings, beads, and insulation. The company holds BBA, KIWA BDA, BOPAS, Euroclass A1/A2-s1,d0, and ISO 9001/14001/45001/50001 certifications across its systems, with up to 60-year design life on flagship products.

SPS Envirowall sells primarily through specification-led channels targeting architects, main contractors, and developers in the UK new-build, refurbishment, recladding (post-Grenfell), and offsite/modular construction sectors. Distribution combines four regional trade counters (Basildon, Cardiff, Newcastle Under Lyme, Wishaw), a sector-specialized direct sales team (Reclad/Refurb and New Build/Offsite), the Benx eCommerce platform for transactional SMB/contractor sales, and NBS Source specification integration. The company is supported by a Training Academy offering PAS2035, EWI Systems, Rainscreen Facades, and Safewall courses across three regional centres, and an in-house fabrication service providing CNC machining, cutting, coating, and kitting of bespoke facade panels.

Revenue is generated predominantly through project-based specification sales of physical building envelope systems, supplemented by fabrication services, eCommerce transactional revenue, and training course fees. Named enterprise customers span housing associations (Home Group, Mears Group, Bron Avon), developers (Knight Dragon, Vistry Group, Joseph Homes, RGB Group), local government (Dartford Borough Council), education (Anglia Ruskin University, Trinity School, Langley Academy), and hospitality (Premier Inn). The company operates within the Benx Group alongside sister company RCM (Roofing Cladding Materials Ltd.) and reports 11-50 employees with active operations across the UK and Continental Europe.
