REFLECTOR: Firewall

[Scott Baker]

MessageThe older firewall protection package consisted of foil faced-Nomex.  The foil face (made of thin metal) wrinkled when bent (such as during shipment).  The foil face would also tend to separate from the Nomex.  Velocity now ships Fiberfrax material, plus a sheet of semi-rigid stainless - which does not wrinkle.

  My factory SS fire wall kit came with wrinkles too.  I used a fiber burnishing pad to produce a machined finish on the SS.  Mostly covers up the wrinkles.  

  I read in VV that they were shipping the SS rolled up so that it doesn't wrinkle as badly.

    I thought I paid $99 for my Nomex SS firewall stuff from Velocity.  About the same as the pieces you bought.  Only thing I didn't care for were the wrinkles in the SS.  I think the wrinkles are pretty common on the factory stuff.  For what I know it may be common with the material and Velocity doesn't have any control over it.

      I purchased my SS from Wicks (somewhere around 60 bucks I think, and ceramic fiber insulation from McMaster Carr for about $30 or so that did (2) 0.1" layers, and I still have about 50% of the roll left- the insulation is good for over 2,000 degrees, I would assume that I would not be flying anyway if the engine compartment reached that temp......

        Does anyone have any experience with the factory firewall materials?  Their price seems a bit high for a sheet of SS and some fiberglass, as described by the factory.  If anyone has purchased this material, would you buy it again from the factory or just go to AS & S?  
        Thanks 
        Joe
