A long-lasting tent hall with sandwich panel walls is an inexpensive way to increase your storage space in just a few days. All you need is a vacant lot, preparation of the ground (e.g. paving stones and footings) and you can have a fully functional warehouse in a few days. Now it is a new version of the hall with THERMO soffit, which increases the insulation of the PVC-covered roof. The THERMO soffit is a multi-layered fabric suspended under the roof of the tent hall.
