Hi Folks
I'm prepping the Cortina for a trip to Italy later in the year and want to make the interior a bit more comfortable (its currently bare metal floors) by putting in some sound deadening followed by carpet. Dynamat seems to be the "Hoover" of the car sound deadening world, but seems to be very expensive. What are the alternatives? Any recommendations and personal experiences welcome
cheers

I've used Lead Flashing tape before with good results, and other people I know have used "Brown Bread"

I've used Noico and Silent Coat, no probs. Bear in mind what it's used for though. CLD (dynamite etc) is good for stopping panels vibrating in sympathy with road noise and speakers, but doesn't really help with road noise itself (it won't stop tyre roar or exhaust noise coming through the floor or bulkheads)
So get some CLD down, some car underlay then the carpet. CLD inside door skins, and if your speakers are in your door, replace the moisture guard with as complete a layer of CLD as possible (makes a good difference to the door speakers)
If you really want to go to town on it, have a research of MLV and CCF on the floor. BUT: this is a proper job, you have to create a sealed layer under the carpet and the MLV is tough stuff. Tecsound is worth a Google as well
Don't use flashing tape, loads of people have but quite a few of these have had 'orrible smells and even melting in high temps

I've used the Dodo branded sound proofing products on my Daimler and been happy with the result. As mr2fc says, I'd avoid going the repurposed building materials route, I tried it once and was unhappy with both the reduction in sound and the smell! |

thanks mr2fc lots of useful info there for me to look into. Cheers goldnrust - I had seen some people suggesting using flashband and similar but I think I would rather have a proper product that doesn't melt or smell, so thanks for the pointer. |

I never minded the smell tbh. My dad used to be a roofer so I grew up with the smell of bitumen etc.
Quite nostalgic.

To the best of my knowledge, Brown Bread was bought out by Dynamat years ago.
The bootlid of the Granny is covered with Brown Bread, and still holding up. (Was also cheaper at the time than Dynamat)
The front doors on my car i used a pack from Silent Coat, which had 4 sheets of sound deadening material, 1 sheet of foam, and 1 sheet of weather proof stuff for right behind speakers.
All very nicely priced and I think nicer to work with than Dynamat

Other option is a spray on material like bed liner.

Use Kilmat. About £50 buys you enough to do your Cortina. Worth buying the roller to make installation easier. Used it on a friends 80's C10 and the difference was night and day - already purchased for use on Woody when I get to that stage. Biggest difference came when we stuck a few panels in the doors, remember that you don't need to completely cover the surface. P.  |

Thanks chaps, all useful. Kilmat is looking like the favourite at the moment.

I use Dodomat. It's British, but made in the EU. Online purchase, cheaper than Dynamat by some distance.
