Insulation material

[Tom Endy]

What is the consensus in the Model A kingdom about what type of body panel insulation material to use. I did a search on Fordbarn and see there is a product called Dynamats that some have used.

Is it better to use a cut and peel material or something that can be sprayed on from a can.

I would prefer to use something I can get from Home Depot or Lowes. Also something that will stay in place and not absorb moisture.

Hey Tom. I installed Dynamat in all my body panels and floor, including under the seats. It really made it feel solid and quiet.

I installed jute padding on top of the Dynamat on the floors for heat.

Sorry, I can't compare with other products tho, as I never used anything else.

Pictures of floor... Dynamat, Jute insulation, Carpet on top. Cozy.

Tom, the Dynamat is not an insulator. It is a sound dampener with no real R value. The big box stores will sell a bubble foil insulation that can be used. Rockwool is another that is good. It is water resistant and as soon as it dries, it is back to normal R value. The jute works well too and can be glued to the foil insulation. Use Weldwood Landau & Top Adhesive for this.

Dynamat make numerous products. Dynamat is a sound insulator as Brent said. They also make Dynaliner, Thermal Insulator. http://www.dynamat.com

I just installed this last December from the belt line down. On the kick and door panels I cut the width just slightly wider than the opening. The floor laid nicely under the mat, surrounded the exposed edges with black Gorilla tape. On the back of cab the three wooden supports the support the seat back hold the insulation firmly in place. There has been huge improvement in sound and insulation.

If you've not attached the top yet I would place it between the batting and vinyl, I personally love the exposed chicken wire.

I'm not sure how I'm going to finish above the belt line yet, but as I already said huge improvement with what I've already done, and the price is great.

Maybe something I do not understand from the pictures. Is teh mat attached/glued to the floorboards? If yes seems it would be difficult to get to the battery/etc.

It's not glued, just lies on top of the floorboards with the floor mat placed on it.
Don't be fooled by the glare from my LED light the firewall is a black ABS insulated panel.

There is a material sold at Lowe's that is made for the roofing industry. It comes in a roll about 10" wide. It is a foil similar to Dynamat, with a very sticky backing about 3mm thick. It is a fraction of the cost of Dynamat and an effective sound deader. About $10 a roll. It's a roofing product, so you know it sticks for good. I used it throughout my RPU cab.

Peel & Seal from Lowes

Used 3 layers in doors & behind kick panels and 2 layers elsewhere as sound deadener. Made a huge difference.

Adhesive types - any concerns when used in door/body cavities of holding moisture?

That was my concern, that is why I used the product I used. If you cut it 1/8" larger the the vertical surface it will stay in place on its own. As you can see my only experience is with a CCPU, cars may have different challenges. The product that M2M and others have mentioned is similar or the same. The filer between the foil is recycled milk jugs. I would not use the bubble wrap that is sandwiched between foil.

lsr490 - Thanks for the tips/info. I tried the link you posted in post 6 - get a 404 page not found error.


My A is also a ccpu, and additionally liked seeing your install of seatbelts - a future project I need to consider.

[lsr490]

I'll try to update the link this evening

I had thought about that also. The Dynamat REALLY sticks and if you pay attention to sealing it, especially around the edges, I don't see how moisture could get behind it (but I suppose anything is posible). They sell a little wooden roller to seal it flat.

Also in the pictire below, you can see the top of the Dynamat is above the bottom of the window so any water getting past the window seal will flow on the outside of the Dynamat.

And lastly, it doesn't rain much in SoCAl. And when it does I don't drive the Ol' Girl.

I used two layers of Dynamat Extreme, custom cut to top of cowl, applied with a small roller; great stuff to work with. I then had custom carpets installed and couldn't be happier!

[PalAl]

I'm in the process of insulating now, I used a productt from Speedway Motors
You have a choice of single or double sided

https://www.speedwaymotors.com/Alumi...ded,32193.html

https://www.speedwaymotors.com/Alumi...eets,2604.html

The tape helped with sealing the seams

https://www.speedwaymotors.com/Alumi...Ft-,94554.html

I undercoated the inside of the body before installing the insulation.
Last year the front of the car was completed, firewall, cowl sides, floor, doors and under the seat. I noticed a huge difference in sound and heat in the car, and the undercoating has rid the "tinny" sound when you close the doors. So seeing I have some extra time on my hands..... thought I would do the rear and complete the job.

I got the cans of undercoat at my local farm store.

LSR490 - Thanks, interesting it has foil on both sides.

I used X-mat sourced from Eastwood for sound deadening. Very easty to work with. Then sprayed 3-M High Strength contact adhesive on it and adhered bubble wrap double faced aluminum insulation that was about 1/4" thick. I even put it in the roof assembly between the wood ribs. The double faced bubble insulation was sourced from a local Menards. (Like Home Depot or Lowes) Both help greatly.
Good Day!

And don't forget that adding Dynamat will add at least 80-100lbs. to the car.

I don't think so. A bulk pack of Dynamat Xtreme weights ~15-20 lbs. I used a little less than two boxes for the interior of my Town Sedan, excluding the firewall and roof.

Hello....I noticed you installed a FIREWALL INSULATOR from Snyder's. How hard was it to install and did it keep out sound and heat as advertised?

[PalAl]

I installed the firewall insulator last year when I insulated the front "cab" section of the car. FW insulator was the first part of the job, needed a little trimming and different bolts for the junction box, removel of choke rod and gas line and any other "things" you may have tucked out of site. BIG difference in sound and heat, made my wife very happy. Even better results with the cowl and floors undercoated and insulated. I would go for it. See post #21 for what I used, I'm doing the back half of the car now.

Any concerns on what this does to the body panels when the next owner wants/needs to do a full restore? is this adhesive easy to remove?

Tell them it's a rare factory original "quiet ride package" option

Another factor is if it is to be sold, makes it difficult for buyers to inspect for internal rust.

[Bob Wright]

Tom,
When doing the restoration on early Victoria I installed a Dyna-mat kit from L.B.& B. Boy was I pleasantly surprised @ how well it quieted the interior & keeping it more temperature tolerant in the cab. Adding to lowering the heat & sound from the engine,I also installed a insulating panel on the inside of the firewall.
Worked for me,
Bob

[whirnot]

I use Fatmat in my roadster, Motorhome, and my wife's 51 F1.
I believe it is similar to Dynamat. It quiets a lot and does keep it cooler. I am restoring a 30 pickup and it will get Fatmat everywhere I can get it.

May have to remove with dry ice.
