Shipping container insulation
Turn a cold steel box into a usable, dry space. We spray closed cell foam directly onto the inside of the container, following every corrugation to create one continuous insulating layer – for single containers through to multi-storey container schemes.
“Excellent service providers. Completing insulation in my storage containers to a very high standard. Prompt, polite and good all round service.”
Containers for every kind of use
Offices & studios
Container offices, studios and workspaces that need to be comfortable all year round.
Workshops
Warmer working space for trades, makers and small businesses.
Storage
Dry, insulated storage that protects contents from condensation.
Multi-container schemes
Larger developments with many units – like the 42 containers at Old Granada Studios.
Single containers through to large multi-unit schemes – just let us know the size and number of containers.
Why containers need the right insulation
Container walls are corrugated, so boards and rolls can't follow the profile without leaving gaps. A cold steel surface behind a gap is exactly where condensation forms – and with no ventilation on the cold side, moisture gets trapped. That's bad news for the container and its contents.
Spray foam bonds directly to the steel and follows its contours, so there's no cold gap left behind the insulation.
- Closed cell foam – its resistance to water vapour makes it the more suitable choice for containers
- Thinner for the same job – a thinner application than traditional insulation, so you lose less internal space
- One continuous layer – walls and ceiling sprayed without joints, around studwork and services
- Declared thermal conductivity of 0.032 W/mK – CE marked to EN 14315-1
Getting container insulation right
Framing and boarding
If you plan to board over the insulation, fit a timber or metal frame stood off from the wall first. The foam then fills behind the frame and reduces cold bridging through it.
Vapour barrier
In most cases closed cell foam on its own stops moisture and condensation building up. Where the foam is to be boarded over, we advise an additional vapour barrier for extra protection.
Flues and heaters
Any flue for a boiler or heater must be protected from direct contact with the insulation, with adequate ventilation for combustion. Check the appliance installer's requirements first.
Good to know: we spray the walls and ceiling. The foam isn't designed for floors or surfaces that carry loads, so container floors need a different approach. All our container work is internal – foam left exposed outdoors would need a suitable UV-protective coating.
