A heated pool is a demanding environment for a lightweight roof. Warm, chlorinated, humid air rises and condenses on the first cold surface. Steel corrodes, and a roof that cannot ventilate will drip.
These reference views show a glazed pool hall with a curved membrane roof, a radial cable roof over a competition pool and an open barrel vault.
Aperçu du projet
| Élément | Champ d'application de référence |
|---|---|
| Application | Indoor pool, hotel, resort, thermal spa |
| Typical span | 15–60 m |
| Formulaires | Curved enclosure, radial cable, barrel vault |
| Membrane et cadre | PVC/PVDF anti-mould; stainless fittings |
| Facteurs déterminants de la conception | Humidity, condensation, corrosion, ventilation |
Les défis que la conception doit relever
- Keep the roof surface warm. Insulation or a warm-air layer reduces condensation on the underside.
- Ventilate at high level. Extract moist air at the ridge and supply fresh air low down.
- Protect the structure. Use stainless or coated steel and isolate dissimilar metals.
- Detail the glazing junction. The roof-to-wall connection must allow movement and stay weathertight.
Formes de toiture dans cet ensemble de référence
Radial cable roof
A radial cable roof spans a competition pool without columns in the water or deck zone. Cable forces, ring stiffness and erection sequence need careful analysis.
Open barrel vault
An open barrel vault shades an outdoor pool and allows cross ventilation. Water is kept away from the pool surround by perimeter gutters.
Matériaux et livraison
Every component in a pool hall should be specified for a chlorinated, humid atmosphere. The frame and fixings matter as much as the membrane.
- PVC/PVDF 900–1100 g/m² with an anti-mould coating
- Stainless A4 fixings and isolation washers
- Thermally broken glazing frames
Foire aux questions
Why do pool canopies drip?
Dripping is condensation forming on a cold roof surface. It is prevented by insulating the roof, ventilating at high level and keeping the inner surface above the dew point.
Which membrane is best for a chlorinated pool?
PVC/PVDF with an anti-mould top coat is common. PTFE is used where long life and easy cleaning are priorities.
Can a pool be covered without glazing the walls?
Yes. An open or semi-enclosed canopy can provide shade and rain protection while leaving the sides open.
