DEWEB® NTA nonwoven for acoustical sandwich panels:
DEWEB® NTA, Non-woven masking material for perforated sheet panels for acoustic sandwich panels.
DEWEB® NTA, is provided with adhesive lines and adhesive-free spaces, which allows air to pass through the nonwoven from the holes in the perforated sheet and allows good sound absorption by the panel's absorbing material.
DEWEB® NTA, is applied to the perforated sheet, with the adhesive lines on the perforated sheet providing good cohesion to the panel.
The gluing used in the acoustic panel industry to glue the soundproofing material blocks on the sandwich panel sheets, is fixed on the nonwoven which allows good cohesion without crossing the nonwoven, DEWEB® NTA thus offering a good obturation.
