Thread: Defender under bonnet soundproofing

I believe Clarke Rubber sell some aftermarket stuff.

Apparently airfilter foam is also good

ufc.com.au - Reticulated Polyester

In Tassie I got something similar from Thomas Parker Rare Spares. For $60 I got a big sheet of under bonnet soundproofing. It has a sticky underside and you just cut out the shape you want and stick it on.

It worked pretty well sorry I would post a pic but don't have that Defender any more

We used the stuff from clarke rubber, seems to do the job fine and hasn't fallen off yet

Trust me - it makes a big difference. The more insulation you can get - the more you can hear and the less you have to turn up the radio. BUT more importantly, the less heat that will be transferred into the cabin, especially when off-road.

I replaced the original stuff under my RR bonnet with

Tru-Fit Carpets - Moulded Automotive Car Carpets for over 30 Years and 700 models

It made a REALLY big difference, and after 2 years is still there. Needs care to fit as the glued back really sticks well, so has to be positioned carefully.

I'd use something like Pyrotek Sorberflex 4kg/sqm sandwiched loaded vinyl with 50mm foam under the bonnet. This is tried and tested, and is designed to reduce noise in industrial, automotive and boating applications. I'd definately go with 50mm foam (especially as you have a diesel), to give decent absorption of noise at low frequencies. Brochure attached.

Do all the Puma's have no soundproofing under the bonnet,does anyone know?
My sons has none.

Maybe a combination of cost cutting & a quieter engine...

Do you think that stuff would work on the inside of the cabin and doors as well? Or use other stuff?

One of the things I've hated about insulation is the price of it. I'd love to do it for the benefits it gives, but the price is hard to justify - especially when it means going without a camping trip or three.
