In my entire rear interior - 1st Layer - Dynamat or the roofing product - silver one side, adhesive the other 2nd Layer - styrofoam panels 3rd Layer - jute padding Front floor 1 & 3
My interior is warm in the New England winter, cool in the summer.
I'm looking into options too. I'm concerned with condensation forming on the metal behind any batt or styrofoam. Has anyone used, or are there any opinions on, closed-cell spray foam insulation over sound deadener like dynamat? There would be no air gap and the r-value would be good. I think the cost is the main drawback.
I ordered the side panels and the headliner from quiet ride and I'm not very happy with the abs products so far. I haven't installed them yet but the initial fit check shows the side panels to be short and the headliner is one piece while my panel has the two piece with center bow.
I’m also planing my headliner for the 37. Nothing available pre made. The closed cell spray foams wouldn’t be to expensive. You would need to do it in multiple stages. With a form backed with Mylar so sticking won’t be a problem. Maybe in 6” sections between roof braces.I’d use a low expanding foam. But be careful it expands with a lot of pressure. One end of form needs to be open. The commercial spray cans are a lot cheaper but you need to buy a spray nozzle to snap on the can. I’m leaning more toward a ridged headliner like a foam board like Sintra or maby ABS covered in cloth. I m not sure it will follow the full curve of the curve of the roof. I don’t think Luian plywood will make the bends without breaking?

These old bolts are in my blood. Hard thing is focusing on just one.

Mark was your abs a kit or did you cut your own .I was thinking of trying to cut my own on my pickup,and am curious as to how to make the pieces when I don’t have the old one to go by
- I cut my own. I used paper/construction paper to make/fit patterns then transferred them to the ABS. That and a bunch of tape to hold things in place.
- The shiny insulation stuff I found on eBay. Cheap stuff. If I were to do it again, I would use the 3M sound deadener I used everywhere else. My dark primer job makes it hot inside no matter what. I'm sure when I get too my lighter, finished color, the heat will be less.
- You should be able to glue stuff to the ABS. I don't think I will, but I have seen fabric glued to ABS plenty of times in the past.
On my 1955 1st Series 1/2 ton Panel. I used Black Butyl Noise Control Acoustic Mat and then covered it with Heat Shield Insulation , Deadener Aluminum fiber. Sticks well and easy to work with. I covered the inside roof and walls I ordered the ABS pre cut from QuietRide Solutions
The one question I want to ask is do you have the headliner bows? On my panel they didn't have them .But there were several drilled holes it might have had them on my panel .I`ve been looking for them and I might go with Metal Fabrication shop. Just to see how they looked and the Length.
