As shipping containers are made from steel, they are prone to condensation, especially with the fluctuation in temperatures. The best method to prevent condensation from forming would be our ply lining and insulation. Similar to insulating your loft, this method prevents condensation from forming and keeps your container a moderate temperature all year round. If you are looking for a more budget friendly option, we would recommend our grafotherm. This product doesn’t prevent condensation from forming, but it will dissipate most moisture that does form. Grafotherm however is not guaranteed to work in incidences of extreme changes in temperature.
