ECOfelt & PETfelt by Slalom

Acoustical Felt That Does More
Slalom’s ECOfelt and PETfelt are soft, flexible materials that act as both an acoustic solution and a design finish. With a warm touch and beautiful response to light, these felts bring depth, texture, and sustainability to any surface. Both are Greenguard Gold certified and VOC-compliant with EU standards.

In addition to flat wall coverage, the material is easy to form, print, cut, or pattern, offering endless creative possibilities with minimal environmental impact. Look to our FELTdesign for inspiration

A Color to Match Any Palette
Available in a wide range of colors: ECOfelt (90% wool, 10% polyester) comes in 55 shades; PETfelt (96% recycled PET) comes in 45 shades. Both deliver color, comfort, and performance.

Endless Applications
ECOfelt and PETfelt can be applied to walls, ceilings, glass, curved surfaces, or furniture to enhance acoustics. Supplied in rolls for large-scale use with minimal visible joints.

Panels can be mounted using glue or Slalom’s custom velcro. The material adapts easily to walls, ceilings, upholstery, curtains, and panels.
