Industries Served

Built for the people who build

From construction sites to food-grade facilities, we match the material to the demands of your industry.

All industries
Construction

Construction

Contractors and developers need insulation and sealing materials on site when the programme calls for them, not three weeks later.

  • Roof & wall insulation
  • Acoustic insulation
  • Sealant & foam
Manufacturing

Manufacturing

Production lines need the same material batch after batch — plant lagging, gasket sheet and packing that behave the way the last delivery did.

  • Plant insulation
  • Gasket & jointing sheet
  • Gland packing
Architecture & Design

Architecture & Design

Acoustic and thermal performance is specified at design stage. We supply the materials that meet the specification on the drawing.

  • Acoustic panels
  • Thermal insulation
  • Reflective foil & tapes
Engineering

Engineering

Civil and mechanical engineers get material certainty — the right grade and rating, in the quantity the job needs, when it needs it.

  • Refractory specification
  • Temperature ratings
  • Reliable lead times
Industrial Plants

Industrial Plants

Furnaces, kilns, boilers and pipework all need lining, lagging and sealing — and need it held in stock against a maintenance shutdown.

  • Refractory brick & castable
  • Pipework lagging
  • HV insulating matting
