Sound Insulation

Recently I had new Double Glazing Units fitted along with new Plastic Cladding. The Double Glazing was installed by a specialist company and the Cladding by a specialist roofing/cladding contractor.
On the exterior there were Boards(Roughly 5'x5'), made from 1/4 - 1/2" compressed composite material, which were removed and replaced with cladding. Since then we have suffered from extreme noise from traffic passing on a nearby road. I had thought initially that the problem lay with the DG units but have now come to the conclusion that it has been the removal of the boards that have caused the noise problem.
I now realise it was a mistake to replace the Boards with Plastic Cladding but the Contractor did not advise me to fit anything under the Cladding which replaced the Boards. I now realise the Boards had very effective noise reduction qualities but that's in the past and I now must move on.
I am looking for a suitable material to fill a 75mm space which is behind(between) Exterior Plastic Cladding and Interior Plasterboard (which has a Tinfoil finish on the side which faces out to the Cladding).
I need a product that will give good SOUND INSULATION. I have good access to the spaces as the Cladding can be removed for the task. Can anyone suggest a suitable product that can be used that would be suitable for this project and that will give good NOISE Insulation?If it also gave some Heat insulation that would also be useful. Hoping you can help.

I think they call it "siding" in the US.

So plastic cladding = vinyl siding?

It sounds as if you are not in the US.

Any stud wall insulation will do the trick if you fill the entire stud space. There are those that are better than others you should check this out.. Make sure that your windows have double glass for glazing.
Hope this helps.
