About the 40ft insulated conex box
An insulated container has foam insulation in the walls, roof, and doors but no refrigeration machinery. It slows heat transfer so the interior stays steadier than in a standard steel box.
Insulation also cuts condensation, which protects paper, electronics, and furniture. Many are former reefers with the machinery removed, and they make a good base for offices or workshops you plan to heat or cool.
Why 40ft?
Twice the floor space of a 20ft unit for well under twice the price, making it the go-to choice for large inventories and conversions.
What fits
About the contents of a three- to four-bedroom home, or roughly 20 to 24 standard pallets.
Who buys a 40ft insulated conex box?
Best for: large archives of documents; furniture and electronics; goods that need steady temperatures but not refrigeration; and big workshops or offices where the insulation is already done for you.
Many insulated 40ft units are former reefers with the machinery removed, giving a smooth, washable interior. Add AC or heating as a modification, or choose the 40ft reefer if you need true refrigeration.

Questions about this container
What fits in a 40ft container?
About the contents of a three- to four-bedroom home, or roughly 20 to 24 standard pallets. Exact capacity depends on how the space is packed.
Can I add heating or air conditioning to an insulated container?
Yes. Insulated units are an ideal base for a wall-mounted AC or heater because the insulation holds the temperature. We can quote it as a modification.
How is an insulated container different inside?
The walls are smooth and thicker, so the interior is a little narrower and shorter than a standard box, but much easier to clean and far less prone to condensation.
Can I rent this container instead of buying it?
Yes. Choose Buy, Rent or Rent to own above and request a quote, and we’ll confirm what’s available for this unit in your area. See how conex rental and rent-to-own work.
Does the quote include delivery?
Delivery depends on your location, site access and the container selected. Share your ZIP or postal code when you request a quote so those details can be checked.
