Insulation material
 

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.

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.

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.

Re: Insulation material
 

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.

Re: Insulation material
 

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

Re: Insulation material
 

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.

Re: Insulation material
 

I'll try to update the link this evening

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!
