We offer a wide range of acoustic sandwich panels, from soundproofing to sound-absorbing panels.
Panels are made of solid sheet metal (galvanized, painted or in RAL color powder coating), which we can additionally equip with anti-vibration foil or anti-vibration coating. We also produce panels made of mineral filler or perforated metal.
Panels are designed for mounting on ready-made HEA / HEB profiles. Standard panel sizes are 1000 mm (39 inches) and 500 mm (19.7 inches). They are designed to get stacked on top of each other to create the desired height of the wall. The design of the load-bearing steel structure is subject to static calculations and varies according to the size and location of the noise barriers.
We will help you to choose an appropriate type of noise barrier and suggest the most fitting shape, length, height and acoustic properties (absorption and soundproofing). The resulting attenuation due to noise barrier shielding depends on the size and spectrum of the sound source, its location above the ground, the distance and orientation of the reflective surfaces around the source, the distance of the protected areas, etc.
We try to solve this complex problem by using a computer modeling of the acoustic situation (LimA software).
For all our products and solutions, we offer effective attenuation guarantee.
For our soundproofing walls, we carry out verification measurements on noise shielding effects. We follow guidelines for attenuation measurements based on ČSN ISO 10847.
