Using Armaflex as an Interior Insulation

Has anybody tried using a product called Armaflex to insulate the inside of their car? It is used in the HVAC industry as pipe insulation. It can be bought in sheets from 1/4" to 1" thick. It is glued with contact cement. It is a closed cell rubber product.The price is low, especially compared to some of these other products like Dynamat or others. Just wondered if anyone could say it's good or bad for this use.

I was just at Lowes looking at insulation for HVAC, was going to use it for headliner, floor and firewall. Came in rolls 16" wide I think, 1/4" thick and adhesive on the back for $15. R value was only 3, but I thought it would be good enough and help deaden some road noise and rattles.

This stuff is as cheap but far denser and it is closed cell. Easy to work with. I have seen the stuff at the Home Centers too but this will work way better. Thanks for the reply.

Yes, been using it since the 60s. You can see it in the trunk of my coupe. It is designed for refrigeration but is also used as a sound deadener on pipes and air ducts.

where can you purchase this armaflex ???

thanks in advance

You can purchase it at any insulation company or insulation distributor. We use Armstrong 520 glue to nail it down. If you know a pipe insulator they are pretty good at this (30 years). When I get back home I'll be doing the interior floorboards too.

if you get the chance some pics of the material in place would be great,,,i hope to soon insulate my 66 from heat and sound,,,thanks

Started on the armaflex interior today. I've only been out of the field for a year and already I'm rusty. Started with the harder areas like the tunnel. 1/2 inch thick armaflex and 520 glue. A very sharp knife.

Then tackled the firewall. Lots of little pieces here, take your time.

What the heck did I do all weekend. Well some of this and some of that.

Of course everything went perfect until I went to mount the console. The thickness of the insulation would not let the mounts line up anymore. So I drew a chalk line along the console and trimmed the insulation along the line, glued the carpet back, and remounted the console. Okay one or two bad words might have slipped out.

Hooked up the gauges and mounted the dash. Next I need to insulate between the trunk bulkhead and interior rear wall.

lookin good ! nothing like a sucessfull weekend to stay motivated !

nice loking job,,,, i hope i remember this topic when i insulate my cuda,,,

Started on the rear bulkhead area.

This is where your age starts to show up a bit. I am sore today from reaching through that access hole all day.

I still have a little more to do in there, but if you want it done right, you have to hire a real insulator. It's pretty easy to find one that will work for food and beer.

Finished the floorboards with armaflex.

Even did inside the doors.

Does it still contain asbestos?

Mesothelioma - products containing asbestos...

I recognize a lot of the asbestos products there on that list, but in my career (1975 - 2010),I have never known Armaflex to contain any asbestos.
Description
Mold resistant AP/Armaflex Sheet & Roll Insulation is a flexible elastomeric thermal insulation, black in color. It is furnished with a smooth skin on one side which forms the outer exposed insulation surface. The expanded closed-cell structure of Armaflex makes it an efficient insulation. It is manufactured without the use of CFC's, HCFC's, or HFC's. It is also formaldehyde-free, dust free, low VOCs, fiber free and resists mold and mildew. All AP Armaflex products are made with Microban® antimicrobial product protection for added defense against mold on the insulation.

I make use of this material at work. As a padding when having to work on the ground or on grading. If it gets wet it will hold water. It cuts nice with an old electric knife. Tough stuff.
