Van sound deadening

[Timmos1974]

Hi
I have just ordered a new toyota proace van for work and would like to make the cabin alot quieter. Seems to have a lot of tyre noise along with bulkhead vibration. I will be installing some new speakers to it as well, so door matting will be going in.
Any ideas
Cheers

Expensive: Dynamat/SilentCoat
Cheap: Roof flashing tape

How about killing road noise ie tyre noise?

Dynamat, if you can afford it. Nothing else comes close. I’ve had a couple of RS powered Connects and I smothered both in the stuff,plus other projects , and it transforms them. Be cautious of some of the materials that aren’t designed to go into a vehicle, as some can emit a diesel/bitumen smell in the summer when things get hot in the sun.
