How much did it cost you? Care to explain the number of sheets/rolls required and the areas that you damped? Some pics would help too

How're you performing, Shrivz?

And how's the damping?

just road noise. I dont think any damping material can help with wind noise.

Yep. With wind noise, you'd have to first isolate the source. Then probably redesign/reengineer the part. Not really DIY. Unless you're navin.

And for the thick ones out there, that's a compliment.

Actually Mercedes benz (dual glazed glass) has managed to do this quite well. I am sure others have too but I have not expereinced other cars in this class (Lexus, Audi, etc..).

Its been sometime now since i've installed the sandwitch..

I'm really happy with it and there is a noticable reduction in road noise and those components sound much much better...

now honestly, I really wouldnt be able to compare the sandwitch with other materials since I havent heard a baleno with the same setup which is damped by another material. But from what is noticable, all rattles from the door panels have vanished. I'm getting better vocals and smoother mid-bass.

overall, its a successful DIY install... and just to confirm, the car does not smell of butyl rubber since I was worried about this. It did give a slight smell for about a day, but it then vanished..

cheers!

navin, dual glazed windows might not be the solution to wind noise - it simply eliminates the symptom of one sensing the noise whilst riding in the vehicle. It doesn't eliminate the source of the noise itself.

Besides, I tried to see if I could create dual glazed windows for my car a few years back when I read about the technology on the then new S Class - one needs to create a vaccuum between the glazing, wider door channels all around for the now thicker profile of the glass, a more powerful window winder motor, & lotsa luck with alignment.

Not something that can be done easily at your local garage by either Ramprasad or Shafique.

the normal windows are generally 1/8 of the inch or near but the merc window are thick as much as 1/2 inch due to dual glass ....with this thick glass there is bound to have better insulation of heat, sound (because of insulation between them).......so replicating this type of stuff will be a little difficult task but if one manage to do it the result will be quite good....

Some posts are better left unread by new comers. And not a Cheapskate, I would rather call you as ultimate DIY guy.

just to confirm I talked to Ram Prasad and he had not even heard of double glased glass. I did offer me a glazed donut though.

SO I called up Shafique who BTW now prefers to call himself SHA(fi)Q-Ue as in "SHAQ-U". He said he could do this mod but it would cost an arm and a leg and it would be cheaper to just buy a car that has this standard esp since one can then get heated seats, aircon, an engine, a chassis etc.. all for free. I asked hi why so he talked about polishing the guides to a N7 finish and using high torque motors with servo control and all that engine-vengine stuff.

The best car that we have experienced in this regard is the Presidents MB Limousine. The bulletproof double sandwich glass is almost 2" thick! You can stand next to the car and shout the choicest expletives at the occupants but they're not gonna hear a word.

There are more engineering marvels in that car but I guess Its better left unsaid.

Actually, you will need hydraulic actuators.
