SoundEx is a premium aircraft soundproofing /insulation includes excellent vibration damping and noise absorption properties. SoundEx is a superior product because of it's thermal qualities, adds less weight to aircraft, and affordability. Make flying fatigue a thing of the past.
Soundproofing / Insulation is placed against outer wall (gluing IS NOT recommended). Each piece is cut to fit between structural members, which in turn hold it in place.
When upholstered panel is installed, soundproofing/Insulation will be slightly pressed against aircraft skin (in most places), creating a damping effect. Note: On larger aircraft where the space is deeper, using adhesive may be needed.
The soundproofing/insulation fills the cavity between skin (outer wall) and upholstered panel. Noise is trapped behind aluminum (foil) layer and absorbed into the acoustic foam core.
