47-55.1 Attaching Jute Padding

[Father&son56project]

What is everyone doing when it comes time to install jute sound padding on the rear panels and ceilings of these old trucks? Will the jute stay in place on the ceiling if I use a high quality spray adhesive, or should I add some sort of straps to support the weight. I did a search but didn’t really find much about this topic. I’m in Ontario Canada where we don’t get the miserably high temps that those of you in the southern U.S. get, so I am hoping that the spray alone will keep it all stuck in place. Any advice or tips from those of you who have done this would be appreciated!

i never could get my insulation to stick to the top of the cab, so I glued it to the headliner. Has worked well for 25 + years. I also glued the insulation to the inside of the door covers instead of fighting trying to get the insulation inside the doors. Just a thought.

I have never found a good spray adhesive. It is OK for the walls (vertical) but I have found the liquid Contact Cement (put a thin coat on both surfaces) is the best.

But for the roof, I added a tar backed roof flashing material directly to the metal, and then I needed somekind of support to hold the fibreboard, padding, and vinyl. There is a gap between the metal and the material, but there is lots of headroom. (see pics)

I'm going to say that you are going to get just about as many different answers as you get people answering.

I'm wondering why Jute rather than one of the newer heat and sound insulation materials on the sides and back of the cab.

The jute I used above my headliner was foil backed and I glued it on top of Killmat sound deadener. I used this glue, it's the same stuff we have been using at work for 20+ years. You can use a Harbor Freight paint gun to spray it on. https://www.amazon.com/DAP-Products-.../dp/B09BFF3FDN

If I had it to do over I wouldn't use jute. I would try something like the Noico Red, which is a closed cell foam. The jute can hold moisture while the Noico will not.

Thanks for the inputs and suggestions! I currently have the butyl rubber sound deadener in place (to control sound caused by panel vibration) and I now just need to add a jute layer for sound absorption (I have a big roll of the stuff already). From the suggestions received, I believe I will try adhering the jute to the hardboard headliner (which I am currently building), and using a high quality contact cement for the vertical panels. I’ll also stick the jute to the inside of the door panels as suggested. Between the butyl vibration dampener, jute layer, hardboard and vinyl, I should end up with a relatively quiet ride. I also learned my lesson about loud exhausts as well, and I have a V6 feeding a single exhaust pipe. I will post the results once I’m all done.

I go along with using the more modern insulators.....but I did use a repop firewall pad on my inside firewall..it had a jute pad on it...I used 3M 77 on it...you'll tear the jute before it comes loose..it had the holes pre punched in the pad and the hole part was still in each hole..if that makes sense..so I took those and did a test with the glue to see how well it would hold
