Sound Installing on Floor Question
I am almost complete in installing sound insulation on the inside of the body skin.
My question is, should the same sound insulation be installed on the floor also? Is there a concern about the heat that comes through the floor due to the exhaust pipe that passes underneath? Is there a heat insulation to apply to the floor? Thank you, |

I coated the floor of my 55 Chevy with tar, then layed down 2 layers of tar paper, jute padding, then carpet. That car was quieter than a new Cadillac. Two layers of tar paper would cut a lot of noise in your Model A.

Re: Sound Installing on Floor Question
John, I installed DynaMat in my '55 Ford Ranchwagon and it really makes the car sound solid. I haven't gotten around to installing it in my Town Sedan yet.
When installing on the front floor ensure you can still get the floor out to access your battery... |

If you put the padding on the bottom side make sure you don't block the bell housing vent.

The vendors also sell a muffler shield that goes between the muffler and floor, and mounts to the tail pipe.
Check out www.b-quiet.com they sell a hood liner that you could put on the floor and get the heat shield and the sound deadening performance all in one, their stuff is not cheap but the quality is awesome. |

Also, insulation can raise the floor carpet, so insul. may need to be trimmed backed where it meets the door sills, etc. We once had a muffler insulator and found it had little effect on noise or heat deflection. Perhaps others have had a different experience. We have the insulated firewall plastic pad from the vendors which does add a little sound and heat muffling. It doesn't come in colors to match the body paint scheme. |

When I did my slant T/S I used the same insulation on the floor inside the body and also over the wood floor board. On the metal floor, I glued it, on the wood just cut to fit. Then I installed the carpets.

Re: Sound Installing on Floor Question
I did the same as Tom on my old 46 Dodge pickup. I used the thick tar paper 4 layers thick and glued it in place with contact cement water soluble I think it was as it is thin like water but actually holds better when cured and dry than the spray out of a can. I also brushed a couple coats of the contact cement over the tar paper and there is no tar paper smell even in the hottest day of the year sitting out in the sun.

Re: Sound Installing on Floor Question
Here is a thread on muffler shields, including my homemade one, post #23.
https://www.fordbarn.com/forum/showt...ghlight=shield I honestly can't tell you if it made a difference, though. |

Coat the bottom side of your floorboards with 3M Super 77 and then Reflectix Radiant Barrier to reduce heat transfer. Cover the top side of the floorboards with Dynomat to reduce road noise. When you're done it will be quiet as a tomb. You may wish to consider adding (XPS) Rigid Foam Insulation between the stringers in your top as well.

Tar? If ever the need to remove it should come...what a mess.
