Posted: Thu Sep 27, 2007 4:05 pm Post subject: Firewall insulation for heat and sound

I'm just about to the point of putting on the front deck of my 7A and thought it would be easier to put some insulation on the aft face of the firewall now.  There are several types advertised -- I was looking for ease of application and good performance in reducing heat and sound from the engine.  Does anyone out there have a favorite type??? Do you feel that it is worth the effort to insulate the firewall?

I'd appreciate your comments

Dave,  I recently installed the aluminized heat barrier by Thermotec (Spruce p/n 08-00600 for the 12X24 in size) on the aft side of my 8  firewall and had a DRAMATIC drop in heat in the fwd baggage hold.  Its 1/16 thick and is comprised of woven ceramic cloth similar to fiberglass with an adhesive back. Added weight is negligible. It does not reduce sound much, if at all.  I have ANR headsets which reduces the sound level to manageable levels.

                                                                                John D RV8 N585JD

Dave,

  

 I used a foam from Wick's: http://www.wicksaircraft.com/catalog/product_detail.php/pid=7836~subid=1925/index.html 

  

 It's available in several thicknesses (I used 1/2  inch on the aft side of the firewall) and I found it easy to apply with a  spray adhesive (3M as I recall) available from  the "aviation  aisle" at Home Depot. I have nothing to compare it to but have been pleased  with it's insulating value for both for sound and heat.

I used Super Soundproofing foam from spruce. I've had it in from day one it seems to be working pretty good but I don't know what it would sound like without it.

Hi Dave,

 In my 6A, I used sound insulation only in the floor. I have no insulation on the backside of the firewall. With my sound cancelling headset, the sound level at my ears is very confortable. There is also no sign of excess heat in the cockpit. I've been flying for 2-1/2 years in Central Florida. It is hot on the ground in the summer in or out of the cockpit and it cools off when I climb above 1000 feet.

 

 Regards,

 

 Richard Dudley

 How hot would it be if the engine caught on fire?

 ========================

  

 Definitely worth the effort IMO.

  

 I used Soundcoat brand Soundfoam HT P/N FF30AHT7 in a 1" thickness.   It's a flame retardant polyimide foam (think Kapton but foamed) with a  aluminized mylar backing.  It weighs 1oz/sqft so only 3/4 of a lb or so for  the whole firewall.  I used aluminum tape to reconnect the various cutout  shapes that fit the firewall topography into a contiguous whole.  It is  expensive but probably the best material for the job.  I have an  AutoCAD file of the 6/6A firewall available.

I used the stuff from Abbey at flightline as others have said.  Doing it was very difficult after the plane was finished and it isn’t near as good a job of sealing up the edges.  Definitely do it while you have access to the back side.

When selecting firewall insulation material, it might be assumed that the manufacturer (amateur builder) looked at flame propagation time or just dismissed the guideline published for certificated aircraft in the AC.  (Which is often a great “jumping off” point in decision making).  

   

Firewall insulation, upholstery covers, carpeting and headliner are often grouped with other “thermal attenuation” and “sound attenuation” products.  Some products can do both – they are not always the same. Fire Suppression  and flame spread were not listed other than in the description.  

   

Often the adhesive used invalidates the purpose for the product in the first place.  

   

The ability to remove it and locate corrosion years later should not be dismissed without reasonable consideration.  Too often in our quest for completion we totally dismiss “fire annunciation” and “fire suppression” objective of safe building.  

   

I had a friend who recently crashed in Virginia, only to extract himself after his canopy burned away adequately.  He was in serious condition afterwards.  

   

Below is the NTSB report of Boriak's accident.  I read in an aerobatics newsletter that he was inverted after the accident and couldn't get out until the canopy melted.

Thanks for the comments I definitely will use some insulation, although I'm still unclear as to which product to use.Currently leaning towards the Flightline Interiors product.
