    Afternoon everyone, had a little search on here and have seen people talking of using standard butyl flashing tape for sound proofing instead of branded stuff (like dynamat). Just wondering if anyone here has actually done it/has any advice? Also does anyone knows roughly how much I'd need to cover the general floor/footwell area?
    Cheers!

    My friend put that standard household thing on the roof and it just pealed away on a hot day, not to mention the smell.

    I have used silentcoat brand even on roof and left it on the sun during the 40+ Celsius days for testing and it still holds.

    my theory is that those materials are similar but the branded stuff that is meant for cars holds mush stronger and doesn't have that much smell.
    also I decided to use the aluminum ducting tape and seal the edges to eliminate the possibility of smell as much as I could even on branded stuff.


    for vibration and panel deadening the manufacturers say it is 50% enough . but I have covered almost everything since I am using it also for extra sound insulation and temperature insulation.

    Well I used the ducting foam over the sound material for sound and thermal insulation (the self adhesive is rated for something like 110 Celsius what is good since the roof gets quite hot during the summer) but I wont use it under the carpet, because a couple of my friends put it and it turned to dust after some time. it is actually really brittle and it rips easally.
    for the floor after the sound deadening material will probably use that recycled fabric stuff that is originally in most old cars

    on the picture is you can see in the middle kinda ripped lines (that is from removal of regular electrical tape)

    so those are my experiences so far hope they help

    I used self adhesive frost king duct insulation. I still used contact adhesive in the roof areas. The floor I'm alao putting down 10mm closed cell foam like those 500mm squares used for home gyms etc also cheap in Wal-Mart. Should keep the noise down.

    Just a thought.....would general domestic carpet underlay prove as a good sound deadening especially on floor areas if stuck down with a high temp spray adhesive?

    new focus RS is amazing
    underlay works fine --the thicker the better....

    plus mine has plenty of waxoyl between it and the metal work of the floor ...the underlay will stick to the waxoyl and also stop any chance of floor damp and rust

    Thanks for all the replies. Think I'll go with a combination of things then! Got plenty of waxoly about as it is, my cousin has some silent coat deadening left over from his Defender rebuild. So I'll strategically use that and then either cover everything in underlay or old foam mats from a friends home gym.
    Cost effective and worthwhile hopfully!

    If u go to any carpet shop they always have a skip they throw all their offcuts in including the underlay im sure they would gladly let u take what u need and that new type recycled foam stuff is flame retardant too!
