Warehouse Spray Foam Insulation
Cut energy costs, eliminate condensation and seal a whole warehouse roof in days — not weeks. Enverge closed-cell spray foam, installed UK-wide by ThermoFoam.
Why spray foam for warehouses
Large warehouses are difficult and expensive to keep at a stable temperature. Vast roof areas and tall internal volumes mean heat escapes rapidly through thin metal roofs, while condensation on the cold deck threatens racked stock, pick-and-pack operations and sensitive goods below. Conventional insulation is slow to install at scale and works poorly around the roof laps, fixings and services typical of distribution buildings.
Enverge closed-cell spray foam is applied to the underside of the warehouse roof, self-bonding as it cures to seal the entire deck, including the laps and penetrations, in a single continuous layer. It can be sprayed across huge spans far faster than boarding, working above racking and around services to create an airtight, insulated envelope without major disruption to operations.
The payoff is lower energy use, a dry condensation-free roof that protects stock and machinery, and more stable conditions for staff and temperature-sensitive goods. With work phased around live operations, the warehouse stays running while becoming cheaper to heat or cool, better protected, and ready for year-round, high-throughput use.
The benefits for warehouses
Vast Spans Fast
Self-bonds across huge roof areas far quicker than boarding out a large distribution warehouse.
Protects Racked Stock
Stops condensation drip onto racking, conveyors and palletised goods stored on the floor below.
Stable Temperatures
Seals the tall roof volume so heating and cooling hold steady right across the floor.
Works Around Racking
Sprayed above existing racking and services with minimal disruption to live warehouse operations.
Lower Running Costs
Cuts the heat loss and energy demand of large, high-volume distribution and storage buildings.
Operations Continue
Phased zone by zone so picking, packing and storage keep running throughout the works.
Nexseal LE — closed-cell spray foam
For warehouses we use Enverge Nexseal LE: a low-exothermic, high-lift closed-cell foam with exceptional thermal performance, strong adhesion and structural benefit. Backed by a 25-year manufacturer warranty and manufactured with an HFO blowing agent.
Sprayed across the warehouse roof underside, the closed-cell foam self-bonds into a continuous airtight layer over the full deck, laps and penetrations. Its low thermal conductivity stabilises the large internal volume against heat loss and gain, while low vapour permeability keeps the cold deck above dew point, protecting racked stock from condensation across wide spans.
- Seals vast roof spans in a continuous layer
- Phased around live racking and operations
- 25-year manufacturer-backed warranty
- Protects stock and stabilises internal temperature

Specification & compliance for warehouses
Closed-cell foam bonds chemically to profiled metal, box-profile and cement-fibre sheets, following every ridge and trough with no fixings, battens or framework. Because the foam carries its own integral vapour barrier, the cold underside that condensation forms on is removed in the same pass — a 15–25 mm coat is typically enough to stop drip, while 25–75 mm delivers a genuine thermal upgrade with U-values down to around 0.18 W/m²K in the right build-up.
Application progresses quickly across open spans, so live operations can usually keep running while zoned sections are sprayed. Where a fire-rated finish is specified, the foam is coated with DC315 intumescent to achieve Euroclass B-s2,d0, and every installation is handed over with full documentation and a 25-year manufacturer-backed product warranty.

Warehouse insulation, answered
Can spray foam be installed while the warehouse stays operational?
Yes. Work is phased zone by zone so picking, packing and storage continue. We plan access, racking clearance and ventilation at survey to spray above operations with minimal disruption to throughput.
How does it protect racked stock and conveyors?
By sealing and warming the cold roof deck, the foam keeps it above dew point so condensation no longer forms and drips onto racking, conveyors or palletised goods, protecting both stock and handling equipment below.
Is spray foam faster than boarding a large warehouse roof?
Considerably. Because it is sprayed and self-bonds to the deck, it covers vast spans far quicker than cutting and fitting boards, and it seals laps, fixings and services in the same pass without separate detailing.
Will it help with both heating and cooling costs?
Yes. The continuous airtight, low-conductivity layer reduces heat loss in winter and unwanted heat gain in summer, helping stabilise temperatures right across tall warehouse volumes and lowering overall heating and cooling energy demand.
What certification and warranty applies?
The Nexseal LE closed-cell foam we install is manufacturer-certified under Agrément 09/4610 and carries a 25-year manufacturer-backed product warranty, giving facilities managers and owners documented, independent long-term assurance across large commercial roofs.
What depth of spray foam does a warehouses need?
A 15–25 mm anti-condensation coat controls drip on most profiled metal roofs. Where thermal upgrade is the goal we typically apply 25–75 mm of closed-cell foam — the exact depth is specified after a free survey.
What fire rating can the system achieve?
Enverge closed-cell foam achieves BS 476 Part 7 Class 1 uncoated, and Euroclass B-s2,d0 when finished with a DC315 intumescent coating. We specify the right build-up for your building's use.
Can you work around a live operation?
Yes — application progresses across large areas each day in zoned sections, so production, storage and staff can usually continue working throughout.
