This 15m by 38m swimming pool tent covers a full-sized indoor pool for year-round training and events. The structure uses a curved-beam profile with 15 meters clear width and 38 meters length, giving an open floor area of 570 square meters. The side height of 3 meters keeps the perimeter clear for spectators, while the arched roof rises to 6.5 meters at the ridge. For venues that want a permanent pool cover without the cost of brick-and-mortar construction, a clear span wedding marquee offers the same column-free volume at a fraction of the investment.
Schools, sports clubs, and resort hotels choose this layout because it delivers a full indoor aquatic environment in under two weeks. The modular design allows the structure to be anchored on a prepared concrete slab or a compacted gravel base with steel stakes. Once the frame is level, the roof membrane is pulled into place and the sidewalls are zipped on from the inside, keeping the installation clean even in changeable weather.
Structural Design of the Swimming Pool Tent
The frame is built from anodized aluminum alloy, the same material used in premium aluminum frame wedding tents. Main profiles are 166 mm by 88 mm extruded sections with a wall thickness of 3.5 mm, connected by stainless steel pins and cast-steel joints. The roof is tensioned over a curved beam system, creating a smooth arc that sheds rain and snow efficiently. All connection plates are hot-dip galvanized, so the frame tolerates the high humidity and chlorine vapor present above a swimming pool.
Wall sections use 850 g/m² double-coated PVC fabric with a blockout inner layer. The fabric reaches M2 / B1 fire rating and blocks more than 99 percent of UV rays. A combination of fixed walls and roll-up ventilation panels runs along the long sides, allowing coaches to control airflow during summer training. The entrance module includes a framed glass door and an integrated canopy, giving the pool facility a professional, finished appearance.
Every bay is sealed with a double-track keder system, so the roof membrane remains taut even under high wind pressure. The white interior lining reflects artificial light evenly across the pool surface, reducing glare for swimmers and improving visibility for coaches on deck. Translucent gable panels can be added to either end wall to increase natural daylight without exposing the pool to direct sun.
Performance Data for Indoor Pool Environments
Engineered wind load for this tent is 100 km/h, with a ground snow load of 50 kg/m². The roof fabric is rated from -30 °C to +70 °C, so the building can host events in both winter and summer climates. A single-layer membrane with a white reflective surface keeps interior temperatures stable under direct sunlight, reducing the load on the ventilation system. When the structure is installed on a concrete ring beam, the entire canopy can be rated for a 20-year service life.
Lighting is suspended from the roof truss through integrated hooks, avoiding any drilling into the fabric. The overhead space is free of intermediate columns, which is why outdoor wedding tent buyers often choose the same clear-span engineering for banquet halls and poolside venues. The 570 m² floor area is large enough for five 25-meter swimming lanes plus a warm-up area, benches, and storage racks.
The interior is designed around a 6.5-meter ridge height, which gives ample room for overhead lighting, scoreboards, and ventilation ducts. An integrated gutter system collects rainwater along both eaves and channels it through downpipes at the corners, protecting the slab and surrounding walkways from pooling. The frame is also compatible with insulated sandwich panels if a venue needs extra thermal control for year-round heating.
Flexible Applications Beyond the Pool
While this unit is installed at a school swimming pool, the same 15m by 38m module works for wedding marquee receptions at resorts, event tent exhibitions, and temporary sports halls. The modular frame can be extended by adding 5-meter bays, and sidewalls can be swapped between solid PVC, glass, or transparent panels. For a custom made wedding tent of this size, the structure also serves as a poolside lounge or cocktail area during evening celebrations.
Because the tent ships in compact bundle sections, it can be transported to remote locations without heavy cranes or specialized trucks. A small crew assembles the frame on the ground, then lifts each bay into position with a forklift or manual winch. This portability makes the design equally attractive for temporary event venues that need a large clear span without permanent foundations.
Frequently Asked Questions
Can a wedding tent be used as a swimming pool cover?
Yes. The same aluminum frame, PVC membrane, and clear-span engineering used in large wedding event structures are ideal for pool enclosures. The key differences are sidewall ventilation, moisture-resistant fittings, and a higher-grade galvanized coating to resist chlorine vapor.
How long does a 15x38m swimming pool tent last?
With a proper concrete foundation and routine maintenance, the aluminum frame lasts 15 to 20 years. The PVC roof fabric typically needs replacement after 8 to 12 years, depending on UV exposure and local climate conditions. Replacing the fabric is straightforward because the keder system allows the old membrane to slide out and the new one to lock in place.
What is the advantage of a clear-span roof over a traditional pool building?
A clear-span tent installs in days rather than months, requires no internal columns, and can be relocated or expanded. It also costs significantly less than a permanent masonry structure while meeting the same wind and snow load codes. Venues that need seasonal pool protection can remove the structure in the off-season and store it for the next year.
