Church-style PVC windows sit in each of the 4 removable sidewalls, so daylight still reaches the interior when the walls are up for wind or privacy. Take them off and the same frame becomes an open pavilion for cross ventilation on a hot afternoon. Footprint is 20 ft by 10 ft with 8.5 ft of headroom, sized for a wedding buffet, a garage overflow, or covered storage for garden furniture and a car. The frame uses heavy-duty painted steel that resists rust while staying light enough to move, and the roof and panels are polyethylene tarp with waterproof and anti-UV treatment. Wall panels are rated at 100 g. Total net weight is 30 lbs, and the tent packs into the included carry bag between events.
