ROAD NOISE

[MIKESAINT]

Hi,

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 sound 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 SOUND Insulation?If it also gave some Heat insulation that would also be useful.

I am also considering refitting the Boards which I think can be purchased from British Gypsum.(The contractor dumped the old ones)

Hoping you can help.Mikie

This

start you off in the right direction.

Not knowing where you are in the world it would be difficult to offer better advice as different countries stock different materials etc

Yup. You want heavy old boards to take out the low frequencies, and then to seal the thing up..and for insulation for heat, some insulation.

Frankly mate, I'd wait till summer, take off all the cladding, shove in celotec insulation for heatloss, and MUILD A BLOCKWORK WALL OUTSIDE IT. then render that..

On the basis that this newsgroup is 'uk.d-i-y' maybe we should in all cases assume the poster is in the UK ....:0)

I live in Scotland where it is noisy(Due to the removal of the Boards) and cold. Mikie

Big silver foiled blocks of expanded polystyrene will work, as will Rockwool. Found at places like Buildbase and Burdens Builders merchants etc

[The Natural Philosopher]

That will help teh cold, but not all te sound.

MASS is what you want. Heavier cladding or prerelably block or brickwork.
