Closed Cell Spray Foam Insulation
Closed cell spray foam insulation for industrial, agricultural and steel-framed buildings, containers and roofs across Walsall and the West Midlands. Fully insured, 10-year guarantee. Free survey.
High-Performance Closed Cell Foam for Demanding Structures
Closed cell spray foam is the toughest, highest-performing spray insulation available. Its tightly sealed cells make it dense, rigid and moisture-resistant, and it bonds hard to the surface it is applied to — adding strength as well as insulation. We install closed cell spray foam for industrial, agricultural and commercial clients throughout Walsall and the West Midlands.
Because it delivers more insulation per millimetre than any other spray foam, closed cell is the answer where space is limited, where a building is exposed to moisture or large temperature swings, or where the structure itself could benefit from added rigidity. It is the material of choice for metal-framed buildings, containers and profiled roofs.
Where Closed Cell Foam Excels
- Steel- and metal-framed buildings — bonding to frame and cladding for a rigid, sealed envelope
- Agricultural and livestock buildings — durable insulation that stands up to a harsh environment
- Corrugated and zinc roofs — sealing the underside of sheeting against condensation and draughts
- Shipping containers — thin, strong insulation that preserves internal space
- Boats and camper vans — moisture-resistant insulation that follows a curved hull or body
- Floor and slab build-ups — see our underfloor and slab insulation page
Where a building is warm, dry and enclosed and cost is the priority, lighter open cell foam may be the better value. We recommend the right foam at survey.
What You Gain
- The highest thermal performance per millimetre of any spray foam
- Moisture resistance that protects stock, vehicles and the structure
- Added structural strength and rigidity from the bonded foam layer
- A 10-year guarantee, fully insured, from an experienced local team
Spray foam is no longer installed in domestic residential properties. For foam in a home that a lender or surveyor has flagged, see our spray foam removal service.
To specify closed cell insulation for your building, request a free survey and we will assess the structure and recommend the right depth and grade.
How It Works
From initial survey to completion — here’s what to expect when you work with us.
-
Free Site Survey
We assess the building, substrate and exposure to moisture, confirm closed cell is the right choice, and set the application depth.
-
Preparation & Masking
We protect surrounding surfaces, plant and stock and prepare the substrate — steel, timber, sheet or slab — for a strong bond.
-
Spray Application
We apply dense closed cell foam to the specified thickness, building a rigid, moisture-resistant layer that bonds to the structure.
-
Inspection & Sign-off
We check depth and coverage against the specification and provide full documentation and a 10-year guarantee.
Frequently Asked Questions
Closed cell foam is dense and rigid, with sealed cells that resist moisture and add structural strength. It delivers a higher insulation value per millimetre than open cell, so it performs where space is tight and where buildings are exposed to damp or temperature swings.
It is the usual choice for steel- and metal-framed buildings, agricultural and livestock buildings, shipping containers, corrugated and zinc roofs, boats and camper vans, and floor or slab applications — any non-domestic structure that needs strength and moisture resistance.
Applied to the underside of profiled metal or zinc sheeting, closed cell foam seals the surface and reduces the cold bridging that causes condensation to form and drip, helping to protect stock, vehicles and the structure below.
No. Spray foam is no longer installed in domestic residential properties. Our closed cell installation service is for commercial, industrial, agricultural and similar non-domestic buildings only.
