Commercial Applications

Buildings we insulate

From small shipping containers to 10,000m² warehouse roofs, spray foam adapts to any substrate and any shape without fixings or fasteners.

Warehouses & Distribution Centres

Eliminate condensation and heat loss across large roof areas. Spray foam bonds directly to profile metal sheeting, creating a seamless thermal envelope.

Aircraft Hangars

Insulate curved and high-level structures without scaffolding delays. Closed-cell foam prevents condensation dripping onto aircraft.

Soffits & Overhangs

Insulate hard-to-reach soffit areas on commercial buildings. Spray foam adheres overhead without fixings or mesh.

Piling Walls & Retaining Structures

Waterproof and insulate sheet-piled walls in basements, undercrofts and car parks.

Shipping Containers & Modular

Transform steel containers into thermally efficient workspaces, offices or storage.

Corrugated Roofs & Metal Cladding

Spray foam follows the profile of corrugated and trapezoidal sheeting perfectly.

Cold Stores & Chill Rooms

Achieve exceptional U-values for temperature-controlled environments.

Swimming Pools & Leisure

Control condensation in high-humidity environments. Closed-cell foam acts as insulation and vapour barrier in one.

Grain Silos & Agricultural

Prevent condensation and temperature fluctuation in grain stores and agricultural buildings.

Commercial Spray Foam Insulation FAQs

Common questions answered

What types of commercial buildings can be spray foam insulated?
Spray foam is suitable for virtually any commercial or industrial building including warehouses, aircraft hangars, factory units, office blocks, retail units, cold stores, shipping containers, and corrugated metal roof structures.
Is commercial spray foam insulation BBA certified?
Not for commercial buildings. Our group company ThermoHoldings Ltd holds BBA Agrément Certificates 23/6963 (closed cell) and 23/6845 (open cell), but their scope is domestic buildings — pitched roofs, external walls and suspended floors. Commercial and industrial buildings sit outside that scope, so the governing evidence here is the manufacturer’s declared values tested to BS EN 14315-1, plus BS 476 Part 7 Class 1 fire performance when coated with DC315. All installations are carried out by Duratite-approved installers who are fully trained, insured and certified.
How long does commercial spray foam insulation last?
Spray foam has a proven lifespan exceeding 25 years with no degradation in thermal performance. Nexseal LE carries up to a 25-year manufacturer-backed product warranty.
How much does commercial spray foam insulation cost?
Typically £20–50 per m² fully installed for closed-cell Nexseal LE. Open-cell Sucraseal is £15–35 per m² fully installed. Every project gets a free survey and detailed quotation.
Do you install nationwide?
Yes. Duratite operates a nationwide approved installer network covering England, Scotland and Wales. Call 01208 832 602 for a free survey anywhere in the UK.
