The list of acoustic panels we produce for the construction of acoustic screens is supplemented by wooden acoustic panels. This panel is made of a 130\/68 mm wooden frame. On the noise side, there are 28 mm thick strips with a spacing and width covering at least 50% of the front panel surface (standard strip width 55 mm, spacing 55 mm). The rear wall of the panel is solid, made of thick boards. 28 mm, tongue-and-groove joints. The panel filling on the absorbing side is made of technical fabric, mineral wool of appropriate density and thickness, and an air gap.<\/p>

We use wood to produce panels: spruce or pine, in accordance with PN-D-94021:2013<\/p>

  • Strength class \u2013 compliant with C24 according to PN EN 338:2003<\/li>
  • Wood defects \u2013 medium class according to PN-D-94021:2013<\/li>
  • No cracks exceeding the requirements specified for medium class wood according to PN-D-94021:2013<\/li>
  • Knots in accordance with PN-D-94021:2013<\/li>
  • Fiber twist \u2013 not more than 5%<\/li>
  • Blue stain: permissible, disappearing when planing, other forms and types of fungal infection not permissible<\/li>
  • Humidity \u2013 approx. 23% according to PN-D-94021:2013 in an air-dry state<\/li><\/ul>

    (The moisture content of the material in the air-dry state is the equilibrium state that is established over a long period of time under normal operation conditions)<\/p>

    The wood is protected with pressure impregnation against:<\/p>

    • Moisture<\/li>
    • Biological corrosion<\/li>
    • Aggressive chemical environment<\/li>
    • The effects of fire<\/li>
    • Panel color: (after impregnation, green, turning brown-gray after about 6 months). Any wood color can be obtained by painting with a wood paint set.<\/li><\/ul>

      The panels have a CE certificate confirmed by a report of the TSUS institute \u2013 Building Testing and Research Institute In Bratislava.<\/p>
