Thermo Tec Install

[cv2065]

For those that installed Thermo Tec sheets on their panels, did you guys cut the sheet to fit the panel exactly and then drill the holes again through the Thermo Tec before install or did you cut the Themo Tec around the drilled holes?

I know it’s not that thick of a sheet, but wanted to avoid any issues with the panel fitting flush.

Thanks!

I drilled through the thermotec in places. Be warned that it gets a lot of the tar-like stuff on your drill bit.
I cut it short on the underneath panel or the overlap and then went to the edge on the overlapping panel, the drilled and riveted through the thermotec. I then added dynamat tape over the seams in select places (mainly the footbox)

Install the Thermo Tec after your panels are installed permanently.

Just to clarify, i put my thermo tec on before i installed the panels. I found it much easier to do it that way, especially in the tight places.

This is what I was thinking, as some of those areas are pretty tight. My main concern was that if I cut the Thermo Tec to the full size of the panel, that it wouldn’t allow it to sit flush when assembling?

Drilling through that stuff gums up a drill bit instantly. The only panels that are hard to do after they are installed are the outer passenger foot box and front and outer driver's foot box.

Yeah, when the panel overlaps another panel, I trimmed the thermotec so that there wasn't any in-between the 2 panels.
Also to clarify, I did the thermotec on the inside of the cabin (and then covered with carpet). The thermotec instructions say that the reflective surface should be pointed towards the heat source (so outside of the cabin) but many on here did not follow those instructions (because it would make the engine bay look like crap) and have been fine. If you are planning on doing it on the outside, of the cabin, I don't know if you'd need to trim or not. On one had, they would sit as flush against the frame, but on the other hand, you may not need the silicone.

Put the sheets on after install. Want the rivets metal on metal.

yes!!

Thanks Dave. So now that I think about it, from a sealing the seams before getting the Thermo-Tec in place perspective, this makes sense, otherwise it would be sloppy trying to get the silicone in-between the Thermo-Tec panels. Question is, how the heck did you cut it to size and fit in there to install?

Use your aluminum panels as templates if are still unattached. Otherwise, I used scrap paper from the FFR boxes and made templates for each panel.

Perfect. Thanks!

Absolutely don't put it between the panels. You were sweating how things fit before. You don't want to add the thickness of the insulation. :o I just finished going through a similar exercise with my Gen 3 Coupe build. Start here and read down several posts: https://thefactoryfiveforum.com/showthread.php?26630-Edwardb%92s-Gen-3-Type-65-Coyote-Coupe-59-Build-Roller-and-Harness&p=333335&viewfull=1#post333335. Different products but the same idea. I'd only recommend the hard to reach places in advance if you want, e.g. the footboxes. The rest of the cockpit I'd do after all the panels are installed.

Thanks Paul. Man that coupe is coming along great! I think I might try that Sikaflex for the panel seams. As prescribed by Dave, Rich and now you, I think I'll measure and cut the Thermo Tec as I put each panel in, but won't put each piece of insulation down until the boxes are riveted. This way, the panels will fit as intended, and the insulation will cover the areas that show the rivets from the inside.

When using peel-n-stick insulation, leave about 1/2” uncovered at the top of the aluminum panels where the bulb seal goes on. Otherwise, the panel is too thick for the bulb seal to fit.

Thanks for the tip John. Would those be the firewall, cockpit and trunk side panels?

[phileas_fogg]

You've got it. Although on my build, I didn't put any sticky insulation on the trunk side panels; I just have painted aluminum. Remember, no bulb seal on the large rear cockpit wall (just the cockpit side panels). And don't rivet the rear cockpit wall in until AFTER you've riveted the upper trunk floor; otherwise the rivets are a bear to install. And install the triangular inner trunk side panels before the outer trunk side panels.

I should shut up now. :)

LOL...Thanks again John. I’ll take all the help I can get!

My Thermo-Tech had wax-like paper on the back. It was easy to place, mark, remove, cut, trim, fit and stick in place on almost every panel after all panels were riveted in place. The only place I didnt was drivers foot box outer and upper. Those I marked overlaps with marker and insulated up to the mark.

Easy Peasy, man.

On my coupe I put masking tape down where the panels overlapped and applied the Thermo Tec to the panels, then trimmed them. I used a nail set to punch through the Thermo Tec from the aluminum side, then marked the holes with a magic marker.
