What are the advantages of Insulated Storage Containers?

Flat pack insulated storage containers provide secure, portable, and fast-to-assemble temperature-moderated storage. Insulation reduces temperature swings and significantly lowers the risk of condensation, helping protect moisture-sensitive items. Construction is robust (galvanised steel, insulated panels) with secure locking, making them suitable for domestic, commercial, and site use across Great Britain.

Important: While designed to reduce and prevent condensation, residual atmospheric moisture can still cause condensation during periods of extreme temperature variation. Appropriate moisture management may still be required. 

What items can be stored in an insulated flat pack unit?

Insulated flat pack containers are ideal for protecting temperature-sensitive and moisture-vulnerable items such as electronics, documents, textiles, food products, and packaging. The insulation helps reduce condensation and create a more stable storage environment.  

However, it’s important to note that insulation cannot eliminate condensation entirely, during extreme temperature swings, residual moisture may still occur. For best protection, items should be dry on loading, and additional measures like ventilation, desiccants, or moisture-resistant packaging can be used.
