Thanks LBM. I think that was a very good point. Now I have to save lots more that 200 bucks for damping the boot :-(

Sorry to disturb your budget.

atlast i have made it to the ICE section.

slightly OT:

Our TV(BPL BZR25) has a woofer and the TV side panels used make those vibrating noises when the woofer is switched on. So i bought a 3 x 3 feet thermacol sheet of 1" thickness, i think it was for 30/- or 50/- and placed it under the TV. Surprisingly the vibrations reduced drastically.

Well does the thermacol work in the car. (only thing it cant be is being flexible i guess)

what you have done is stop the cabinet under the TV from resoanting the panels are probably still resonating. to damp them youd have to s=place something heavy on top of them or use acoustic damping material like dynamat.

thermacol will work in the car it can also work as thermal insulation if used on the roof. but it is fragile.

SRShrikanth · 18th March 2008, 10:43

Traditional Dynamat experience is to essentially increase weight on the panels to reduce vibrations. Sound / Vibration damping is the outcome.

Does that mean that thermal damping ( predominantly the objective for the roof ) will also be equally effective.

OR

Is there any other thermal damping material used primarily for roofs that can be procurred in Bombay.

With summer fast approaching and a few planned long drives expected - am keen to ensure a cooler ride - if possible.

All suggestions are most welcome.

Look forward

Thermacol can be used for thermal insulation not for sound deading.

Thermal insulation sheets are easily available. Also known as heatlon.

These are not even close to the density of sound deadening materials. No point using them for damping.

SRShrikanth · 18th March 2008, 11:21

Hi B&T,

Where do you reckon I can acquire 'Heatlon' in B'Bay and will these dealers also have them implemented on the car roof.

Any indicative prices, please.

I clearly do not intend to use them for damping. Only for thermal insulation.

Thank you & look forward.

Cheers cheers:

Earlier I was avoiding damping my car due to budget constraints , but after going through this thread it seems that damping can be pretty affordable too , especially Fonomat , and I plan to go ahead with it as soon as I get hold of my new amp (KAC9104 probably)

.

I have noticed that the hatch door of my Alto rattles a lot when all windows are closed and the sub is on full blast. I have got a 12inch sub in a sealed box that sits facing toward the hatch door. But i guess damping will take care of it.

Can someone let me know the approx price of getting the front two doors and rear hatch of my Alto damped with Fonomat ??

Heatlon is perfect for heat insulation. It is a greyish material used to cover the split aircon pipes also.

I think anyone who does car top fittings should be able to help you out. It is available in various thicknesses. Based on your car, they should be able to help you select the appropriate thickness.

I think the best alternative to commercially available damping would be self-adhesive rubber sheets.

Shrivz has damped his car with sheets he got from a tyre shop (IIRC this was posted in the 'car advice from the gurus' thread)

However such rubber sheets are not easily available everywhere.

What is the price of fonomat you are getting.

Hi kkr2k2. Pls don't flame me for this - you can even place a brick on top and that will serve the purpose.

hahahaaaa.... good one.

when navin said to put something heavy on top, considering the horizontal area on the TV what came to my mind is a stone, what a coincidence!!!

On the serious note, can some one suggest a better thing, ... wait!! How about a Stabilizer? Does it qualify to be a heavy thingy?

Sorry, it was in another thread.

Here's the link http://www.team-bhp.com/forum/produc...tml#post430338

If only we could find out where else these sheets are used, it would be much easier to source them.

Read this post and the ones after that.
