Sound deadening

Postby Alex'n'Ane » Tue Sep 27, 2011 3:52 pm

I am about to fit a new carpet set, so the interior will be coming out, and thus I am after some advice with regards to what to use as sound deadening material? I Have read else where that roofing flashing tape works well?

Not sure about the tape but using rubber backed felt underlay (Something like this) certainly helps.

The first step to take to reduce noise levels is always to block off direct paths for noise transmission. Check every grommet and spare hole in the bulkhead and floor, and replace or seal them as appropriate. Fancy thick felts are a lazy way of doing this, but grommets are cheaper. I'm sure they help, but can't recommend any specific type.

Using sound deadening on the bulkhead really cuts down the engine noise. It's available from all our morris suppliers. You can buy plastic "nails" (look rather like large drawing pins) to fit it. These pierce through the material and go into small holes already in the bulkhead. It's a bit of a pig to fit as you have to lie under the dash to fit. I have it fitted on my Traveller.

That's what I used. One layer on floor, under and behind back seat and two layers on the bulkhead. I think that came to 6 metres.
Older and more confused than I could ever imagine possible.

If you have any water leaks then felt on the floor is not such a good idea as it retains the moisture.
You can get stuff like self adhesive roof flashing for sound deadening if this is an issue.

Yes,I would worry about the damp / felt issue. Also 11mm is pretty thick.
I am considering DEDSHEET,(details via google) seems to fit the bill.

BTW. Wilkinsons do Evostick flashband tape. £5.98 for 3.75m x 100mm.
could also be usefull.

Noisekiller is supposed to be the best for this. IIRC they do a range of different types of sheeting, and you can get advice on which type to use on which bit of the car. I think it's self-adhesive.

I'd agree, only use underfelt (and indeed carpet!) if you are confident that you've eliminated all the leaks from your car :wink:

And again I'd agree: make sure you've blanked off all the open grommet holes in the bulkhead and the floor - and anywhere else where sound could get in from either the road or the engine - using blanking grommets.

And speaking as a van owner, Boots muffles wax earplugs are excellent :D

I used foam carpet underlay. Also some camping mat material. It is under the carpet, rear seats and also against the bulkhead on the dashboard side - took the gloveboxes our and just put it there. Works great, my doors just let wind noise in now :lol:


Just J-j-j-jiggle it a bit.
