1. A structure comprising a floor, and a collapsible canopy made from a substantially air-impermeable material and having at least one tubular rib, the canopy being further provided with an air inlet port by means of which the interior of the at least one tubular rib can be connected to a source of compressed air, and being movable by the supply of compressed air to the tubular rib via the air inlet port from a collapsed state in which the at least one tubular rib is deflated to an inflated state in which the at least one tubular rib is inflated and supports the canopy in such a way that the canopy encloses an interior space above the floor and forms a roof and side walls of the structure, wherein a rib insulating layer is provided in the interior of each rib of the at least one tubular rib, wherein the rib insulating layer comprises a polymeric fleece or felt sandwiched between two reflective foil layers.
