A friend of mine has been doing his whole car in flashing tape from B&Q.

From what I can tell, its just as effective as the proper stuff, but heaps cheaper.

[Guest Ted]

is flashing tape all that effective at reducing vibration though?

 

how thick is the tape?

isn't brown bread really heavy?

Have a peek at this thread on MIG...

Thats his car in the pics.

£17 for a ten meter roll of the stuff compared to the silly prices of dynamat etc mean you can afford to put several layers on.

Interesting.

Looks like I've found something new to do!!

[RichE 0]

Me too

 

Time to strip the car and goto town again, this should compliment the £300 of dynamatt extreme my car has!

 

 

You can buy the tape here.

about £25

Similar to flashing tape, but more effective, you can get rolls of self-adheisive, non-gritted roofing felt from DIY places.

 

I got a roll from Wickes. I think its 1m x 10m and cost about £12.

It has a plastic coating on one side, with the glue on the other and IS the same material as brown bread/dynamat etc.

[Guest Ted]

ok this is the result of this post :

 

 

 

 

i used roofing underlay, self-adheisive simple to apply its about 4mm thick - 3layers ideal

 

comes in a roll of 1x10 metres £27, still got a fair bit of it over but it still worked out cheaper than flashing tape to cover the big areas of the doors etc (at £17 but you need to use several rolls).

So where is most effective to do in the 205? Boot floor, rear quarters and doors?

 

Does it add much weight to the car? I'd love to sound deaden mine but after spending loads of cash tuning it i don't want to be weighing it down accesively!! Are these cost effectrive methods particuarly heavy?

[Robbie G 4]

Check out woosey's sound deadening article on the parent site. It will make a small difference to the weight, depends how much you add.

[Guest Ted]

the stuff i used was fairly light - much lighter than dynamat

 

its doesn't add much weight thankfully, just try to be efficent with where you put it

 

i just did the doors and rear quarters. The boots not really worth it me thinks as the stardard mat is very heavy and does a good enough job - adding more proofing would just mean more weight .

 

under the back seats IMO is just more weight aswell as the seats do a nice job to reduce the noise already

OK cheers guys.

 

Ted, do you think it has made much of a difference? Is road noise/exhaust noise, etc significantly reduced?

I currently building some domestic loudspeakers, and could do with something to stick on the inside of the cabinet to dampen things, this stuff sounds like it could do the trick; would you agree?

 

Also going back to more 205 related things, I ripped out the fibrous wadding stuff in the boot floor recently as it had turned really skanky. What would be something similar to replace it with?

[Guest Ted]

Ted, do you think it has made much of a difference? Is road noise/exhaust noise, etc significantly reduced?

reduces high speed noise, cuts down on vibrations (ergo rattles), makes the doors very solid too.

 

the more you add the more significant the noise reduction

 

but then you have to balance noise & weight etc

 

so its really a personal thing

[Guest Serg]

I have and Matt Cony had too.....it reduces a bit of road noise and tightens up the speaker sound a little but it mainly gives the door a nice clunk sound when you close it!

[Guest Serg]

hmm may give that ago as well then. how thick perspex should i be using?

2 or 3mm - the thinnest you can buy. It's about £15 for a sheet.

[Guest Serg]
