Sound-absorbing materials - Import export

The panels have standard dimensions with heights ranging from mm 1000/1 250/1 500 and lengths from mm 2950/3950; they can be made to be housed inside HE12O/1 40/1 60 profiles. The panel frame consists of horizontal and vertical beams with different insertion sections of mm 100 for HE 160 profile, mm 80 for HE 140 profile and mm 60 for HE 120 profile; The 20mm-thick rear side, representing the sound-insulating part of the barrier, consists of a battened or tongue&grooved matchboard. Inside the panel sound-absorbing material - mineral wool - with density 90 kg/mc, thickness 50 mm, supported by wooden pads to create an inner tube suitable to enhance the acoustic features: the sound-absorbing material is protected by a green or black smoke- and UV-resistant silicone net with 90% fine weft. The front face has slats for aesthetic/wool keeping purposes, which can be mounted diagonally, vertically or horizontally. An "EPDM" seal is fitted on the vertical sides of the panel front to lock

Inside the panel no sound-absorbing material is fitted. The front face is embellished with motifs and drawings of various kinds. An "EPDM" seal is fitted on the vertical sides of the panel front to lock the panel inside the HE profile; an "EPDM" flat seal is also fitted at the panel bottom to avoid breaks between the panels. Bolts and screws include stainless steel screws, 15-micron passivated ring nails, galvanized clips. The wood used is impregnated pinewood; all the wooden elements are impr

The primary characteristic of a wooden noise barrier is its eco-friendly nature and its praiseworthy appearance. Thanks to the use of wood, a fully renewable and recyclable raw material, the selection of woods coming from controlled forests, and a treatment with eco-friendly mineral oils, a barrier has been designed which remarkably reduces the environmental impact of roads and railways. The precision of processes, the possibility to include wide windows and the pleasant decoration of the panels make this noise-abatement system a praiseworthy architectural element.

 The acoustic features of TECNOWALL wooden noise barriers have been certified. The autoclave-impregnation treatment with especially made and antiseptic eco-friendly mineral oils guarantees its long life.
Structural elements are made part of laminated wood and part of solid wood of large-section resinous species.
 Decorative elements are made of solid wood of resinous species. The sound-absorbing material consists of minera
