Depending on the chosen option, an aluminum-framed tent can be used in summer or winter conditions. Tents designed for summer use often have soft walls and can be equipped with air conditioning systems, transparent tent fabric, or "Blackout" fabric to protect against heat and direct sunlight. In summer, options with rigid walls or cold PVC windows can also be implemented. Tents designed for winter use feature warm glass windows or insulated sandwich panels. Pneumatic roofs are installed in snowy areas to reduce snow load.
