These barriers are particularly effective in overcoming coincidence dip resonance found in stiff lightweight composites such as plywood sheets and hollow core panels.

  • Highly modified flexible open-celled polyurethane foam
  • Targets low frequencies
  • Mold resistant and highly flame retardant
  • Easy to cut and install

Dimensions (mm): 1200 x 2000 x 12

MuffleFoam Eggbox is a chemically inert product that will not dust or migrate, even when subjected to high-velocity airflows. Tested at 10000 fpm for 4 hours. MuffleFoam Eggbox also has the ability to act as a membrane absorber across the full frequency spectrum when specified with the correct material thickness & choice of facing. High mass ensures FireTech gives excellent damping performance when applied to rigid substrates, greatly improving sound breakout.
