    Hi guys:

    I am wanting to line floor pans with new sound/heat deadening material after POR-15 treatments. As opposed to Dynamat, are there other alternative suppliers that make a product of similar performance at less cost? I really don't want to pay the brand name fees, if you know what I mean.

    Suggestions and sources welcomed. Thanks!

    Chris

    I used the same, or similar stuff. When you go to Lowe's, look for a roll of what looks like bubble wrap with aluminum foil on both sides. It was like 20 per roll, I used 2 in the car, 1 more behind the back seat and in the trunk.

    I used Dynomat

    I used dynomat in mine and yes it was exspensive. I drove it home and what a difference it made. Even with bad rubber seals the car was so much quieter. It sounded as if I had gotten into another car. I will check at work and see if there is a good alt.

    I read an article in Muscle Car Review about insulating older cars.
    They used Dynamat, but I was surprised in the way that they
    used it.

    The article described the straight flat areas of your car as being
    similar to the skin on a drum. The longer the span, the more noise
    resonates from the drum. They used strips to cut down on the cost.
    They did not cover the entire floorpan, firewall, hood, roofline(under
    the headliner). They just used strips to cut down the noise waves.
    Looking at the pictures, I would say 50-60% of the bare metal was
    covered. They stressed to use it in the straight flat areas.

    On top of that, they used the aluminum backed fiber padding for more
    of a noise and insulation barrier.

    Dynomat

    Mine is installed in squares and strips. There aren't any solid pieces anywhere on the floors, or in the doors. That alone will cut down in cost. Also Dynomat is heavy and dense. I wouldn't want to line the whole car with it, I would have to beef up the supension.

    go to Lowe's, visit the roofing section and it's called "Flashing" (normally used around chimnies, seams and such when roofing). it comes in a 6"x25' roll and has the aluminum backing. it's like $14.99 a roll. i bought 4 rolls, done my entire floor and doubled the layers over my firewall and trans hump and still have almost a whole roll left. well worth the money :thumbs2:
