SoundEx™ is a premium aircraft soundproofing / insulation that incorporates excellent vibration damping and noise absorption properties. SoundEx™ is a superior product compared to other products on the market because of it's thermal qualities, adds less weight to aircraft (4.5 oz. per sq. ft. for 1-1/8" thickness and 3 oz. per sq. ft. for 7/8" thickness), and affordability. Materials are available in bulk or soundproofing template kits. Stop the yelling and make flying fatigue a thing of the past. Improve your quality of flight with SoundEx™.

Decibel Reduction Data
Decibel reductions will vary depending upon how well your aircraft is currently insulated. Our latest data indicate that you should expect noise level reduction from 4-7 dB(a) and 10-15 dB(c). From singles and light twins to corporate jets, SoundEx™ is the noise reduction option of choice. Pilots and passengers can fly and communicate in comfort.

Flammability Requirements
All materials meet FAR 25:853 (a), Appendix F, Part 1 (a) (1) (ii) for flammability. Certificate provided with each kit or bulk order.

Soundproofing Template Kits
All pieces are clearly printed, numbered, and ready for cutting on the templates. Cutting time is estimated on an average of 1-1/2 to 2 hours. For example, the Basic kit for a V35 Bonanza should take an experienced cutter about 60 to 90 minutes to cut, adding another 20 to 30 minutes for a Deluxe kit. For a late model B58 Baron, cutting the templates should take about 2 hours for the Basic kit and 2-1/2 to 2-3/4 hours for the Deluxe kit. Kits are for originally configures cabins.
