Porto Suspended horizontal or vertical ceiling absorber
Beyond its acoustic performance, Porto is CHOC‑certified in accordance with DIN 18032‑3 (class D2), guaranteeing its resistance to ball‑impact safety tests in sports environments.
This compliance allows acoustic treatment to be integrated into ceilings in gymnasiums and multisport halls without compromising safety requirements.
CHOC Certification : laboratory‑tested compliance
The Porto acoustic ceiling light has been tested by the independent laboratory LABOSPORT in accordance with DIN 18032‑3, applicable to ceiling elements likely to be impacted.
Tests performed :
- 36 handball shots at 85 km/h
- Specific tests for suspended elements (distance, angles and hangers compliant with the standard)
Results :
- No structural deterioration
- No alteration of suspension systems
- Full preservation of functionality and safety
Porto is therefore a CHOC‑certified ceiling solution suitable for high‑intensity sports environments.
Resistance to humidity and chlorinated environments
Porto is also designed to maintain its performance in humid environments or in chlorinated atmospheres. To ensure durability, the acoustic ceiling light was tested by CSTB in accordance with NF EN 13964, which evaluates the resistance of suspended ceilings under extreme conditions.
Test results :
Class C: 62 days at 95% relative humidity at 30°C → no degradation observed
Class D: 64 days in chlorinated atmosphere (10 ppm) → no degradation observed
Suspension system also certified
The fixing elements (cables, suspension kits and angles) were also tested for 64 days in a chlorinated environment, with no apparent degradation.
Thanks to these performances, Porto is perfectly suited for demanding spaces such as :
- swimming‑pool changing rooms
- aquatic centres
- spas
- steam rooms
- professional kitchens
- other high‑humidity rooms
This resistance adds to its excellent acoustic performance and its CHOC certification, making Porto a reliable and durable solution for public buildings (ERP) and architectural projects subject to significant technical constraints.
Design & formats : adaptable architectural solution
Developed as a horizontal or vertical suspended system, Porto stands out thanks to :
- a compact 12 mm rPET acoustic fibre
- integration compatible with technical ceiling voids • rectangular format (1,200 to 2,400 mm × 300 to 1,200 mm)
- round format (Ø 600 to 1,200 mm)
- availability in 30 fibre colours in stock
Its installation allows visual structuring of ceilings while integrating high‑performance acoustic correction.
Recommended Applications
Porto is particularly suitable for:
- gymnasiums and multisport halls
- educational facilities
- sports centers and multipurpose complexes
- halls and high‑traffic areas
Acoustic performance : effective correction of large volumes
With a performance of 0.95 alpha‑sabine, Porto helps to :
- reduce reverberation time
- improve speech intelligibility in large volumes
- limit sound propagation
- optimise acoustic comfort in rooms with high ceilings
The combination of high acoustic performance and impact resistance enables ceiling treatment in spaces where it is often excluded for safety reasons.
