... and the ceiling stays up.
Sports halls are usually quite busy. Therefore, the ceiling systems used must meet many requirements: Not only good acoustics are crucial, but above all safety and functionality. Ceiling systems for sports halls from Lindner are tested according to EN 13964 in classes 1A/2A/3A.
Metal ceilings which are exposed to a lot of mechanical stress as it occurs in sports halls, swimming halls or schools require ball-impact resistance in accordance to EN 13964 D or DIN 18032-3.
During the testing, the ceiling systems must withstand impacting balls at a speed of up to 65 km/h and must not be deformed too much or even be destroyed in the process – and no elements must come loose. Different classes can be determined depending on the intended use: gymnastics rooms (class 3A), swimming halls (class 2A) as well as sports, gymnastics and multi-purpose halls (class 1A).
Lindner offers three ball-impact resistant ceiling systems, tested according to EN 13964 in classes 1A/2A/3A:
- Hook-On Ceiling LMD-E 213 BWS
- Hook-On Expanded Metal Ceiling with Accentuated Joints; LMD-ST 213 BWS
- Expanded Metal Ceiling, Directly Fixed; LMD-ST 700 BWS
The Hook-On Ceiling ensures a smooth appearance. It has acoustically effective perforations with a maximum diameter of 3 mm and accentuated joints in both directions. The Expanded Metal Ceilings are characterized by a wide range of design options due to variable mesh types, shapes and sizes – they are available in both modular and planar optics.
