Sports ceiling constructions must not only meet sound insulation requirements but also pass testing for ball impact resistance according to DIN 18032-3 and shock resistance according to EN 13964-D. The aluminum panels offered by Metawell® have an extremely rigid structure, so deformations by ball shots are almost impossible. The Metawell® ceiling may also -optionally- provide the heating of the hall. The copper pipe tubes mounted on the back side of the ceiling convert this acoustic ceiling into both an acoustic and radiant ceiling.
Advantages of Metawell® Sports Hall Ceilings
Heating sports halls using radiant ceiling heating has many advantages over conventional solutions:
- Complies with sound absorption requirements
- Large-scale aluminum sandwich panel
- Weight incl. meander only max. 14 kg/m²
- Mountable with countersunk head screws on all standard rails for dry construction
- The screw heads remain visible, though they become indistinct between the perforation
- Optional copper pipe covering possible
- Because of the sandwich structure, an extremely even design is visible
- Smooth and flat ceiling structure with a sealed cavity
- Dirt cannot settle down
- Balls cannot get stuck behind the ceiling
- Better hygienic air quality inside the hall
- Attractive appearance
Installation
Installation is simple and carried out using standard CD rails and drywall screws – special and expensive substructures are not required.
- A coarse and fine grid construction with 900mm spacing is mounted to the ceiling. The spacing of the fine grid depends on the width of the ceiling panels. If the width is 1480 mm, three fine grids must be provided per panel; in each case, the spacing on the longitudinal edges and in the center of the panel is 700 mm.
- The perforated ceiling panels have a pre-drilled 2 mm hole instead of a 6 mm perforation hole at the points where the drywall screws have to be set – which clearly determines the positioning of the screws. The screw head diameter of 5.9 mm is very similar to a perforation hole, so the attachment is hardly noticeable from the floor. All edge panels are supplied with over-dimension. The excess material is cut off during assembly. This levels out building tolerances and creates a uniform shadow gap towards the walls.
Schematic sketches
According to the building regulations of the federal states, certain standard or minimum dimensions are recommended for the dimensions of sports halls. Metawell® provides schematic sketches for these.
| Gym Hall Type | Minimum Dimensions | Minimum Room Height |
| Single | 15 x 27 m | 5.5 m |
| Double | 22 x 44 m | 7 m |
| Triple | 27 x 45 m | 7 m |
Heating Calculations
On basis of the building physics data of the sports hall, the heating load of the hall is calculated by the planner, whereby the room height has a great influence on the temperature distribution. In order to ensure the desired temperature in the area where the athletes are, a correction factor should be included in the calculation.
| Example: For a sports hall with a height of 7 m, a heat load of 25,000 watts is determined. The correction factor according to the table is 0.7. The heat load to be provided by the ceiling is therefore 35,700 watts. |
Acoustics & Reverberation Time of Ceiling Elements
In order to ensure speech intelligibility during training and to keep the noise disturbance for athletes, trainers, and the audience low, acoustic measurements are undertaken. Room acoustics is one of the fundamental planning tasks when designing a sports hall. Corresponding acoustic equipment has to be provided.
Subject to the kind of room use and the space volume the reverberation period in sports halls should amount to 1,4 to 2,5 sec. and in multi-purpose halls even to 1,1 to 4,4 sec. DIN EN 18032 explicitly requests the planning of room acoustics:
- Speech intelligibility in the single and in particular multiple sporting activities
- Speech communication possibilities of the athletes among themselves
- Speech intelligibility when using a PA system in sports halls with audience
- Noise and stress-free sports
Sustainable and Energy Efficient
Metawell®sports hall ceiling elements consist of an aluminum carrier panel with copper pipes. Both materials are excellent heat conductors. Thus, Metawell® sports hall ceilings respond extremely fast and achieve high-performance values. When the ceilings are not in use anymore, they can be recycled without additional preparation.
