Flashing tape as sound proofing - any used it?

feenster99 · 27 Jan 2006 at 18:55

Hi folks,
I'm wanting to do some sound proofing on my Megane Coupé. I'm a cheapskate, so was going to give the flash tape a go. Has anyone used it? Does it work reasonably well (not expecting miracles!)?

Where's best to buy it from?

yes i have. it is the same as the other big brand tosh out there and is infact easier to apply due to the fact that it is in 5" wide strips as opposed to big squares.

i also did a pc case with it, made a world of difference.

Cool, that's what I like to hear

Only criticisms I heard of it was that it was slightly less effective than Dynamat standard etc, and that as it was Bitumen based, it set on fire quite easily. Are either of those claims founded?

What does sound proofing actually consist of? Do you line the entire car with material?

Doesn't this make things much heavier and loads of work involved?

it is exactly the same material as dynamat, go get some for yourself to find out.

flashing tape can vary in thickness form store to store but the reality is it is so much cheaper that if you really want you can do more than one layer.

2 layers makes a fair difference over 1, but 3+ really doesnt make much difference.

as for fire issues, that is BS too. like i said, i had it inside the case of my pc, i holesawed a 120mm hole through one panel. it got so hot that the bitumen did melt and drip everywhere, but no fire.

in fact, my brother did an experiment with the exhause on his mnimoto, he wanted to try and heat wrap the exhaust, he used flashing tape. it became silly hot, the bitumen melted away, but no fire.

so someone has been BSing you lol

try it

Cool. Where did you get yours from? I've just been to B&Q and Wickes and neither had any cheap decent stuff.

Well, to reply to my own post, Wickes had a 1M wide roll that was about £40. B&Q had the 15cm wide stuff, but it was about £20 or so for 5m length. I thought it was about 10m and £8. What did you pay?
