A wall sandwich panel is suitable where a hall, warehouse or workshop needs to be enclosed quickly, but its usefulness depends on the conditions on both sides of the wall. Before choosing, establish whether the interior requires a specific coating, chemical resistance or hygienic solutions, and compare the declared insulation and reaction-to-fire class of the particular product. Also check whether the system includes suitable joints and accessories for corners, openings and the roof connection, since these details often determine the airtightness and durability of the enclosure.

A single building may contain a warm workshop, a cool warehouse and a room with a lot of moisture side by side. They do not need identical panels, but their joints must form a coherent system. Thickness is selected after checking thermal insulation, load-bearing capacity and fire requirements. None of these conditions should be assessed solely on the basis of the others. Record the planned temperature in each zone and the heating period. It matters whether the door opens all day or only a few times a week. A product packing room may need different conditions from a warehouse for empty boxes, even with the same floor area.
