Underfloor and Slab Insulation for Non-Domestic Buildings

Heat is easily lost through the floor of a working building, and a cold, damp floor void can undermine everything else you do to insulate a space. Spray foam applied to a suspended floor, container base or slab build-up seals the structure against heat loss, draughts and ground moisture in one continuous layer. We install underfloor and slab spray foam insulation for commercial, industrial and agricultural clients throughout Walsall and the West Midlands.

Floor and slab work almost always calls for closed cell foam. Its density and rigidity stand up to loading, while its sealed structure resists the moisture that rises from the ground or condenses in an exposed void — the two things that ruin softer insulation over time.

Typical Applications

  • Suspended and raised floors in commercial and agricultural buildings
  • Shipping container bases — sealing the underside against cold and damp
  • Portable cabins and site accommodation — warmer floors for year-round use
  • Mezzanine and platform decks in warehouses and workshops
  • Slab build-ups in non-domestic premises

What You Gain

  • Less heat loss through the floor, and lower running costs
  • A drier structure, with moisture sealed out from below
  • Durable insulation that copes with loading and movement
  • A 10-year guarantee, fully insured, from a hands-on local team

Not sure whether floor insulation is the priority for your building? Our spray foam insulation team can assess the whole envelope — roof, walls and floor — and advise where insulation will make the biggest difference.

Spray foam is no longer installed in domestic residential properties, including domestic floors. For foam in a home flagged by a lender or surveyor, see our spray foam removal service.

To insulate a commercial, agricultural or portable floor, request a free survey and we will recommend the right specification.

How It Works

From initial survey to completion — here’s what to expect when you work with us.

  1. Free Site Survey

    We assess the floor structure — suspended deck, container base or slab build-up — its use and exposure, and set the specification.

  2. Preparation & Masking

    We protect adjoining surfaces and prepare the underside or build-up so the foam bonds cleanly.

  3. Spray Application

    We apply closed cell foam to the specified thickness, sealing the floor against heat loss, draughts and moisture.

  4. Inspection & Sign-off

    We check depth and coverage and provide full documentation and a 10-year guarantee.
