The Fiero Store carries two inner door insulation products. One they call "jute" which looks like heavy felt for noise and drafts insulation. The other is a waterproof mylar shield which they indicate was original equipment. I haven't pulled my doors apart yet but I plan to very soon in order to install new dew wipes and felt window guides. Anyone know if both were used together from the factory or is it a choice between one or the other? Assuming they have never been replaced before should I expect to replace one or both of these at this time? Since it's my daily driver I would rather not tear the doors apart only to find there are other wear parts I should have been prepared to replace.

they were both factory. this onehttp://www.fierostore.com/P...spx?s=57660&d=83&p=1 was glued to the inside of the door panel originally the other one was a thin piece of paper that was attached To door itself.

Yes, it was paper attached to the doo with jute attached to the door panel

Ayup, when I was utility at GM those jobs I did and he is absolutely right, we got the door pads from the supplier and in the case where it had electric windows we would put the door pad on a machine to punch a square hole, I didn't build Fieros our plant did cutlass's and others so the door pads had the electric window buttons in the door pad. but back to the insulation, it gets glued onto the door pad as shown and the paper goes on the door itself. we had a ribbon type glue that we had to put on the paper and a hot melt type glue gun we spread on the jute type insulation. the paper is to keep water off the other insulation and that jute is for sound deadening.

Have you looked at Mighty Mat? It's a foil back insulation that has great insulation and sound deadening properties. I'm using it on the firewall of my '87 GT, & it works so well my wife wants it installed on her '88. You can get it in a variety of thicknesses for what you need. I used the 1/4" thick on mine.
