I have used house foam underfelt its quite nice easy to cut and doesn't really soak up water.

 

Changed back to thick traditional underfelt just sits better over all. Also easy to get from my suppliers and used on a bunch of other things. 

 

Either works just as fine.

 

 

What about those thick grey shifting blankets, would they be any good?

Pretty much underlay. They might have a bit more movement in them so not that stable/rigid.

 

If you were to ask me what I would actually recommend, i would say go buy some from an upholstery shop. I sell it for $50 a meter at 1.8 wide. You won't need 2 meters for a car or 1.6 for a ute, pay cash for a peace the guy has had under the bench and get it a bit cheaper.

A friend just bought this up in another forums I am on (NZ)

PET & PP Quality Sound Deadener / Deadening (Self-adhesive) 80cm x 50cm $8

How would something like this compare do you reckon?

other than the perceived 'mass' of it vs KilMat

Or do I just recommend Kilmat?

I think its for his track dedicated Car (fast Street car)

thoughts?

[tortron 69,273]

track car?

get some fitted ear plugs and save the weight

[Bling 22,329]

Yeah unless they like the idea of a padded cell spec track car... At least the killmat doesn't look like you're a frequent flyer at craft stores.

That would probably do the job of underlay quite nicely.  And at that price it's worth a shot.

Initial feedback is that it works. 
you still need to seal the doors with traditional rubber/tar and alloy mat but it helped the floor and hatch area a noticeable amount. 
stuffing the very rear across under the latch with 3layers killed a lot of drone.

My car has extensive sound deadening as I wanted something a little quieter but still fun to drive. A combination of dynamat and roadkill were used but the results amazing

Look forward to hearing how these other products perform.

I haven't used it yet

Have just ordered some kilmat.  Any advice on some additional undercarpet insulator?  Pref not underfelt as it may get wet, options for a sticky backed foam?

I just came back inside after doing the back of my commer van. I opted for the usual underlay and shag carpet over sound matting. Reason being it is easy enough to drag out and dry if it gets wet.

Amazon suggests that Noico Red closed cell foam insulation is often purchased with Kilmat.

Would that be suitable as the carpet underlay? Or would you still put felt with it as well?

no.

I would recommend going to buy some under felt from a local supplier. usually 50 bucks a meter 1.8 or two meters wide.

probably wouldn't put that under carpet as you might find it able to compress and movable causing it to brake down where under felt is a lot more hard wearing.

I would put this type of product on a fire wall or on a ceiling.

Is there is a foam underlay you would reccomend?

I want to put something in the landrover but at the risk of doing a deep water crossing and underfelt would have to be removed entirely to dry...

You can use foam underlay like in a house, but unless it's closed cell foam it will all absorb water. And that foam underlay will hold it longer than underfelt.

 

If you are thinking the under felt is going to get that wet I probably wouldn't be putting carpet in it.

 

I would look at rubber/vinyl matting.

 

But really depends how often you plan on getting the carpet and underfelt saturated. 10 times a year? Cause dehumidifiers work a treat in closed up vehicles to dry out carpet.

[tortron 69,273]

you mght look into a mass loaded vinyl for that

Cheers, I still have quite a roll of marine carpet I was looking to use. 

 

So even close cell foam I'm going to get into trouble?

[tomble 283]

I've noticed there are companies like auto custom carpets that have form-fitting carpets specific to different years of various vehicles.  LHD but I wonder if they can make to order.  Their stuff can optionally come with "mass backing" which is apparently great for sound deadening and look. 

Spenny though, US$763 for carpet + mass backing for a complete replacement for my car.

But then I'm not sure how that stacks up vs proper padding/sound deadening and carpet for the whole car, and the faff of getting it all in..

Probably cheaper to have an upholsterer make you a set locally, at least you know the fitment will be right. There is a place in aussie that does carpet as well as here. You'd have to do own homework on peoples experiences with them though.
