Acoustic panels
Acoustic panels are an effective sound-absorbing product and, at the same time, effective ballistic protection. The grooved ballistic panels protect against the dangerous reflection of bullets from steel or the formation of steel splinters during the impact of the bullet, thus protecting the shooter against loss of health and life. The panels absorb a significant part of the projectile energy, thus extending the life of the walls and ceiling of the shooting range. The panels arranged in a tight manner significantly prevent projectiles/ricochets from escaping at their connection. Panels, depending on the required flammability class, are produced in the entire thickness section or only with the top layer. Ballistic panels are made of rubber pulp/granulate bound with polyurethane. The panels can be produced in a different color or size. The panels can be glued or screwed to the wall or ceiling.
Acoustic panels (grooved) are intended for:
- Walls and ceiling in closed and open shooting ranges;
- Shooting and tactical courses;
- Side protection;
- Safety dividers;
- Shooting houses
- Safety partitions;
The panels have the following properties:
- bullet/ricochet traps;
- damping the sound of a shot;
- damping noise and vibrations;
- they are an excellent insulating layer;
- they are resistant to weather conditions;
- they are easy to keep clean.

In relation to other types of surfaces used at shooting ranges, the acoustic ballistic panel has a much better sound absorption coefficient, which shows the effectiveness of its use.
The acoustic sound absorption index of the ballistic panel is αw = 0.75.

Acoustic panel sizes:
- Anti-ricochet acoustic panel 610x610x50mm, side edge - flat;
It is possible to make ballistic elements in a different size and shape.
Our products meet all the requirements for materials used at shooting ranges.
The acoustic ballistic panels completely absorb the projectiles fired in their direction, thus preventing the formation of ricochets.
