    Getting ready to install Koolmat on the firewall and am wondering what different methods have been used to secure it. Some have used dabs of red RTV and others seem to have used high temp glue of some sort. I would like to be able to look behind the stuff at annual inspection time. Any thoughts or comments, especially from those who are flying with Koolmat installed would be appreciated. do not archive -------- David Maib RV-10 #40559 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=163980#163980

    Opinions differ, but I would install it on the cabin side of the firewall, for the exact reason you mention...you can inspect the firewall better at annual time without anything covering the engine side. Nothing to absorb oil and gas. On the inside, in some areas you may be able to friction fit it. Any glue/RTV will make it difficult to remove.

    Subject: Re: Koolmat Installation
    Kelly As the Koolmat is fiberglass / silicone, I don't think oil and gas absorbtion will be a problem. In my opinion, placing the mat on the cabin side of the firewall will defeat the purpose of the mat as there will be little protection from gases that could come through firewall penetrations. On the engine side, the mat would perhaps cover some of the cracks and holes that would otherwise allow the gases through. I don't know how much risk there would be of AL rivets melting in the case of an enine fire, but I have seen a video of the VAN AL vents melting under heat. If this is a risk, the mat on the firewall side would provide protection. I would ask the A&Ps on the lis to chime in on the issue of firewall inspections. I do note that the Koolmat website shows th mats on the engine side of the firewall. See: http://www.koolmat.com/aircraft.shtml Another product to consider is : CONTEGO from A/C Spruce. See: http://www.aircraftspruce.com/catalog/cspages/contego.php Perhaps his could be used to protect the penetrations as well.

    Subject: Re: Koolmat Installation
    Les, just my opinion, and industry practice. You want to be able to have a clear view of the firewall. They do get cracks or wrinkles from hard landings, etc. You cannot see that from inside the cabin and you can't inspect it if you have an insulating cover over it. Any material that has a fabric or fiberglass mat will absorb oil, ultimately a fire risk. I'd rather let air do the cooling of the firewall. The insulation on the inside will do just as well at insulating. Any sealing should be done at the seams and penetration holes, and no insulation will improve that. Every certificated aircraft has the insulation on the cabin side of the firewall. With the wiring and cables that penetrate the insulation wherever you mount it, you are not going to take it off unless you are doing an engine change. Far too much labor. Materials used on the firewall assembly should be fire resistant. I heartily agree with those that replace the AL vent boxes with SS.

    I just got my trim controller from Stein and have a question that might be helpful to all. I got the air switch. It has a Pitot input and a Static input. Is there any overwhelming reason to plumb the static port into the aircraft system? Why not leave it open to the cabin pressure? Other than being off a few MPH from time to time would it make any big difference?

    Hi Kelly I understand the need for inspections but surely no RV10 pilot would ever admit to a hard landing. I think the difference in view is that I am thinking more in terms of fire protection rather than insulation. As well, could not the firewall inspection for creases etc be done from the cabin side? I would think that if a hard landing (not that I would admit to it) was a concern, I would want to look at the interior weldments that are visable only from the interior. The Koolmat could also be installed so that it could be lifted for inspection of the firewall. As far as oil is concerned, given that I am in line for a Subaru, expect that oil leaks will be just a not so found memory of life with m Lyc O-3060.

    Subject: Safety-Trim Air Speed Switch Question
    The answer is YES, plumbing to static line is important, especially if you have your airplane tested for the pitot static test to fly IFR. The test equipment can ruin any piece of equipment that is only connected to one of the lines. The test draws a vacuum on both lines simulating a rise in altitude. With both lines (pitot and static) connected to the test rig the net differential pressure from pitot to static is near zero and everything is fine. However, with only one line connected the vacuum is drawn across any instrument connected to only one line. There's a great chance of ruining the instrument connected to only one line. I know first hand. I had to pay for the rebuild of my airspeed indicator when the pitot line got disconnected during the test! Bang. So please connect both lines to the Air Speed Switch!

    Subject: Re: Koolmat Installation
    I'm going to use Koolmat on my RV-10, I'm planning on putting it on the firewall side for the following reasons. 1) The Silicon side of koolmat is quite impervious to oil and fluids. 2) Heat transfer is a function of three modes: Convection, Conduction and Radiation. Limiting heat transfer into the passanger compartment should best be accomplished by reducing each of these factors. Insulation on either side of the firewall will be effective at reducing conduction, (convection should not be an issue because there's no airflow over the firewall per se) However, Only by insulating the firewall side can we reduce the effects of radiation. The radiated heat of the engine and exhaust system will land on the firewall and heat the firewall. With insulation only on the cabin side, the firewall effectively is heated and re-radiates into the cabin. The insulation on the cabin side only slows the progress of heat flow into the cabin it doesn't prevent it from occuring. With insulation on the firewall side, the radiated energy cannot heat the firewall to begin with and therefore should provide less cabin heating. 3) Accoustically it should be quieter. For the same reasons as in # 2 for heat, accoustically it should be quiter if the firewall is not radiated with sound energy. Theoretically! will see in practice hopefully the end of this year. So those our my reasons for insulating the firewall side. note, I do plan on corrosion proofing the rivets on the firewall side before applying the koolmat.

    Kelly, Based on your concerns below, I think the Koolmat may be a waste of money for you. You may be better served by looking at a product designed specifically for the cabin side of the firewall. By placing the Koolmat on the cabin side of the firewall, you eliminate one of the principal benefits of the Koolmat, that of reduction of radiant heating of the firewall and everything that is attached to it. The fibers in the Koolmat are impregnated and would be difficult to absorb moisture. Certainly being able to inspect the firewall is valuable, however I think this could be done from the cabin side. I used red RTV and the engine mount to hold mine in place. The most challenging part was neatly making all the cutouts for the various items passing through the firewall.

    I see on William's and a couple other builders web sites that they used some foam under the Archer nav antenna to keep it level. Sounds like a good idea but no clue what type of foam I can use for this and other potential uses in the future..... Will the white packing foam that came in the QB kit be used?

Nope. But I have seen it work very well in many other applications besides this one. The numbers say it would take a catastrophe to break the bond--thousands of pounds loading against the window--at which point the strength of the bond becomes a moot point. So, no, I haven't checked, but I still I trust the application. Also, it's a bit of an apples/oranges comparison because the SilPruf stretches so much further before breaking. That's what makes it nice for preventing the hairline cracks.

    Subject: Re: Safety-Trim Air Speed Switch Question
    Bob: That's interesting and good to know. I was also planning on an airspeed switch and was wondering the same thing as Gary. Couple questions?? Do you have to install special ports for the equipment to hook up to or will it hook up to the pitot tube and static ports (two) as installed?? Does the system test an alternate static port operated from inside the cabin as well?? Do you know why TruTrak would say its fine to just vent the static port for their ADI to the cabin?? That instrument is usually a backup for IFR so one would think that TruTrak would expect to have the pitot/static systems tested. Thanks Mark ----- Original Message ----- From: Bob-tcw To: rv10-list@matronics.com Sent: Thursday, February 14, 2008 2:49 PM Subject: RV10-List: Safety-Trim Air Speed Switch Question The answer is YES, plumbing to static line is important, especially if you have your airplane tested for the pitot static test to fly IFR. The test equipment can ruin any piece of equipment that is only connected to one of the lines. The test draws a vacuum on both lines simulating a rise in altitude. With both lines (pitot and static) connected to the test rig the net differential pressure from pitot to static is near zero and everything is fine. However, with only one line connected the vacuum is drawn across any instrument connected to only one line. There's a great chance of ruining the instrument connected to only one line. I know first hand. I had to pay for the rebuild of my airspeed indicator when the pitot line got disconnected during the test! Bang. So please connect both lines to the Air Speed Switch!

    I'm glad there is a difference in your mind. That is the only place you will find any difference in R value or acoustic value. If it is on the front side, you will NOT be able to properly inspect the firewall.

    Hey Guys, We're not this far yet, but very interested in the discussion. If removable insulation is desirable, is there a velcro product that could be used here?

    We built our own aircraft....we are not certificated...WE work on our aircraft because WE like it, NOT paid to do it...not because it its labor intense. We build our aircaft to EXCEED industry practices. I know there are a lot of good A&P's out there...I just wish someone would take away their bubble gum, duct/speed tape and safety wire fixes.

You want to be able to have a clear view of the firewall. They do get cracks or wrinkles from hard landings, etc. You cannot see that from inside the cabin and you can't inspect it if you have an insulating cover over it. Any material that has a fabric or fiberglass mat will absorb oil, ultimately a fire risk. I'd rather let air do the cooling of the firewall. The insulation on the inside will do just as well at insulating. Any sealing should be done at the seams and penetration holes, and no insulation will improve that. Every certificated aircraft has the insulation on the cabin side of the firewall. With the wiring and cables that penetrate the insulation wherever you mount it, you are not going to take it off unless you are doing an engine change. Far too much labor. Materials used on the firewall assembly should be fire resistant. I heartily agree with those that replace the AL vent boxes with SS.

    Subject: Re: Safety-Trim Air Speed Switch Question
    Our Air Speed Switch (ASW-1) connects into your standard pitot and static system, you just need to "T" into each of the respective lines. Using it with an alternate source of static pressure from inside the cabin is not an issue. Under all normal cases that static source is closed off, when the Static test performed it certainly checks to ensure that the alternate static source doesn't leak. If you ever use your alternate source in actual conditions the pitot and static system will already be close in differential pressure so no issue. The only problem I know of is during the Static Test when your airplane is sitting on the ground, but the test equipment takes your pitot and static lines up to 20,000 ft. Regarding the recommendations of other manufacturers I can only speculate, so don't take this to the bank. But perhaps they are using a solid-state pressure transducer that can withstand large differential pressures. The real problem is for transducers or instruments with some sort of diaphragm mechanism.

    Subject: Re: Koolmat Installation
    OK... Koolmat is intended as a FIRE BARRIER. It is intended to be installed on the engine side firewall. Ask all the NASCAR drivers who experienced catastropic engine fires last year how it worked, it's standard equipment. If you have a problem with inspecting your firewall, don't use it. I have it on mine, it is held by a perimeter bead of red RTV. I can peel it off without much trouble, I have done it once already. If you want to bat around the inspection of the firewall issue then fine, I can pull my stainless steel heat valves off, loosen my eyeball cable guides, remove my firewall mounted electrial connectors and see my firewall in about an hours worth of work. BUT....if I prang a landing, the last thing I'm worrying about is the firewall. The firewall is really not a structural piece. The weldments and adjoining structural members are the parts that will absorb the impact and show signs of STRUCTURAL failure. Yes the firewall will wrinkle, but get on your back, scoot your ass under the panel and see what is really bent. Most of us elected to use the koolmat to prevent heat buldup in the tunnel. It is a fiberglass mat with a pure silicone finish. It is NOT a insulator...it is intended to keep FLAMES from breaching the firewall. So screw your indifference. Rob has spelled it out..read the spec sheet on the stuff and decide if you want it or not...Look at a tube and frame aircraft, the firewall only is intended to keep flames away from the cockpit...not provide structural integrity.

    Looks like Koolmat installation might become the next 'primer war' <gag>. I installed Koolmat on the engine side of the firewall about 12 months ago when 'tunnel heat' was the hot topic (bad pun - sorry). It was my attempt to reduce any radiant heat affects that drove tunnel temps and I used red RTV for attachment. I also installed a layer of Koolmat on the tunnel floor, attached with velcro in answer to Lew's question below. I have also heard of builders here in Oz using snap fasteners and even s/s screws to pin the mat in position, but I doubt that velcro would be up to the mission in the engine compartment. Just another 0.02 worth.

    I'm struggling a bit with this concept of radiant heating of the firewall. It is behind the engine baffling, gets airflow after it passes through the cylinders, so only the exhaust system is radiating any direct heat towards the firewall, absent an uncontained fire. Maybe this product would help on the lower half of the firewall, but surely there is no significant radiant heating of the upper half of the firewall. Other than at very low airspeed or taxing, there probably isn't significant radiant heat on the lower firewall either.

    The manufacturer "is" the builder, not the various suppliers. The RV-10 is a great example of a lot of experimental products coming together into a unique final creation by us. At times like these, the words of Richard come to mind this Christmas as we discussed the 51% Committee accomplishments and his role as Co-Chair. "There are no standards in Experimental Built - there are now 29,000 finished experiments flying in the system". In the certified world, every prudent manufacturer has a firewall that allows for inspection at each annual. The firewall tells a lot about dissimilar metal corrosion, wire chafing, and stresses endured during the previous period since last inspection and other valuable observations. One side tends to show these better than the other. Probably Kelly's extensive experience as an IA and his desire for safe operations clouded his views on the experimental portion of this pursuit. Maybe the words "on a wing and a prayer" came to his mind. Periodically, get a trained pair of eyes to look over your shoulder as you travel down life's highway.

Dave Many thanks for such a detailed post. Where I live it can go from -40F in winter to +90F in summer. Thermal expansion of joints around windows etc is an issue that I have been concerned about. On the strength of your recommendation, I have ordered the video and hope to put it to good use.

Nope. But I have seen it work very well in many other applications besides this one. The numbers say it would take a catastrophe to break the bond--thousands of pounds loading against the window--at which point the strength of the bond becomes a moot point. So, no, I haven't checked, but I still I trust the application. Also, it's a bit of an apples/oranges comparison because the SilPruf stretches so much further before breaking. That's what makes it nice for preventing the hairline cracks.

    This wasn't from the "Group buy" was it?

I got the air switch. It has a Pitot input and a Static input. Is there any overwhelming reason to plumb the static port into the aircraft system? Why not leave it open to the cabin pressure? Other than being off a few MPH from time to time would it make any big difference?

    Lew When I spoke to Patty at Koolmat today she suggested using a product called "gorilla snot" (I kid you not) to secure the Koolmat. She said it was also called "3M Yellow" so I think this is it: http://www.3mestore.com/62214006090.html?WT.mc_id=3M-com-AtoZ-Super-Weathers trip-Adhesive She also mentioned that you must use a silicone based adhesive to join sheets.

    Subject: Re: Koolmat Installation
    Hmmm I think that there are two different applications being discussed her. I for one am only concerned about fire protection. Granted this is a very low risk, I have read a few stories about engine fires that make me want to spend a few dineros to mitigate this risk. Do a search on the VansAIrForce website for some interesting tales... Interestingly, one of the places where fire can enter the cockpit is via the floor. It seems that an engine fire will flow under the firewall and melt the bottom skin. I plan to line the full floor area with Koolmat to mitigate this risk as well. The other application being discussed is about insulation. Here I don't care so much. I fly in places were a -25c days is not uncommon in winter. So if its heat, bring it on....

It is behind the engine baffling, gets airflow after it passes through the cylinders, so only the exhaust system is radiating any direct heat towards the firewall, absent an uncontained fire. Maybe this product would help on the lower half of the firewall, but surely there is no significant radiant heating of the upper half of the firewall. Other than at very low airspeed or taxing, there probably isn't significant radiant heat on the lower firewall either.

    So why not a solar energized steam turbine? Or algae derived biodiesel fired steam boiler? Where's the real experimental here anyway? Lycs and auto derived internal combustion is sooooooooo passe, eh? Perhaps Rick is right...if you can mount the Koolmat on the front side in a way that it is easily removable for inspections, it just might be the trick, although in Alberta, you probably need another insulation on the back side.
