Shipping containers are strong, durable, and built to perform in all conditions. However, as temperatures drop, even the toughest containers can benefit from extra protection. Winter in the UK brings cold air, heavy rain, and more moisture- conditions that increase the risk of condensation inside containers.
By adding insulation, you can easily winter-proof your space, protect stored items, and maintain a comfortable internal temperature. These simple upgrades help containers perform at their best throughout the season.
How to Stop Condensation in Containers
1. Add Quality Shipping Container Insulation and Lining

The most effective solution is shipping container insulation. Insulating walls and ceilings keeps the interior temperature stable. It also prevents condensation and creates a more comfortable, usable space.
Lion Containers can line containers with durable plywood or hygienic boards for a clean finish. The result is a dry, ventilated container ready for storage, office or workshop use.
2. Apply Grafo-Therm Roof Coating

Grafo-Therm coating strengthens your container insulation. It absorbs moisture before droplets form, keeping the ceiling dry. Lion can spray this coating evenly across the container roof to prevent leaks and extend the container’s life.
3. Use Moisture Traps for Extra Protection

Moisture traps help manage humidity inside your insulated container. They’re simple, cost-effective, and ideal for short-term use. For the best results, combine moisture traps with professional insulation and roof coating.
