Hi Jim

 

I do have some pics but they are at work and I'm on vacation...sort of.  Actually I'm building a carbon fiber hot tub cover if you can believe it.  An interesting project and big $$$.  But it has to meet code and be very stiff so carbon works well.  Anyway, I'll probably have to get in to work to get pictures but the barrier is a 1/2 lb/sq. ft. barium/vinyl sheet.  For the floor, I have a sandwich of Nomex/barrier/Nomex.  For the firewall, I used 1/2" fiberglass against the firewall, then barrier and foam absorber on the inside.  The firewall blanket was covered in film but the felt/barrier/felt was placed under carpet so it didn't need anything.

 

I also used 1/2" of felt on top of the glareshield.  This helped damp the noise from the firewall that did escape and absorb noise generated from the canopy.  That was covered with a fire retardant black wool/polyester blend cover.  This made it look plush while getting rid of some noise.

 

One thing to make CRTAIN of is that ANY barrier type blanket MUST have a tight fit.  If you can make it to OSK, I'll be talking a lot about that.  If not, there is an article I wrote for Sport Aviation that is suppose to publish some time this year, (I wish they could be more specific as to when).
