I am looking for ideas/products for the reduction in noise from the 130.
Sensible replies on what products are available in the UK. for under the bonnet. And is there anything I can do about reducing the heat from under the driver and passenger seat box. Ours gets very warm... not nice when its 40c plus. 2010 Defender 130 HCPU 1991 110 RFSV PERENTIE www.landybitz.com.au |

I have a mix of NOISEKILLER and DYNAMAT. They're both good products and IMHO they work well used in combination - there's not clear "one fits all" winner.
NK is great as far as it goes (under carpets in rear tub etc) and Dynamat works well stuck to the upright bits... NK here http://www.noisekiller.co.uk/ DGARDEL was looking at fitting a 2.2 acoustic cover to the 2.4. I don't think he has done it yet, but that would be an interesting mod for reducing engine noise...

I have done the inside of my 130 but we have yet to see any sun here in UK  |

Noisekiller seems to be fairly hopeless from what I have read, as it is open cell, and as such will hold water.
For anti vibration noise, dynamat is what you want - or silent coat, which is the same stuff, but much cheaper and comes in sheets. Not so sure about the heat, not a problem over here! I would look into heat insulation that doesn't hold water. I'm sure there are fire/heat resistant foams, but whether they are suitable I don't know |

You could line inside the seat boxes with camping roll mat. This is a cheap way of deadening sound. Buy a roll mat or two at any camping shop, cut it up to the sizes you need and stick it on.You can also put it under any carpet or floor mats and it will act as a sound suppressor.
I saw someone use it on the outside of a Defender. He put it on the underside of the rear seat boxes to stop that noise from stones hitting the bear metal. Don't know how long it would last in that application but he had it a good time and it was still working. Don't think it would be O.K. for under the bonnet as it might not be fire resistant. 1982 88" 2.25 diesel 1992 110 200tdi csw -Zikali 2008 110 2.4 tdci csw-Zulu 2011 110 2.4 tdci csw-Masai |

Some good ideas here, I too thought the noisekiller was supposed to be a good product.
Friend of mine did the seat boxs on his series 3 Dormobile, I dont want to take mine to bits really. This Dynamat might be the go... 2010 Defender 130 HCPU 1991 110 RFSV PERENTIE www.landybitz.com.au |

FYI, I used 1.5mm thick rubber sheet glued to the roof,side panels and wheel arches in the back of my 110,with a rad-haz kit over that, (made of the same stuff as camping mats,with a metal foil covering).
In the front compartment I glued rubber sheet onto the roof with the rad-haz kit in between the roof trim.I also used tesco camping mat underneath the vinyl floor covering,plenty of camping mat left over for the doors. *Under the bonnet I used felt from Frosts,which is flame retardant,I used glue but wasn't overly impressed so used cable ties around the bonnet supports aswell. You need quality Hi-temp contact adhesive as the glue will come unstuck in hot sunny weather,thats about £12 per liter x3, 6 meters of rubber sheet £35, rad-haz kit £12 (bargain,lol), 2 foil backed tesco camping mats £9, felt £12. most was posted so maybe another £30-40 postage, that rubber sheet is heavy sh*t  .
It's definitely worth doing,so much quieter. And for the vinyl seats I used one of them beaded seat covers,absolutely no sweaty back either. 
*I should add:I glued the felt to the underside of the bonnet,not just thrown over the top of the engine. Last edited by jimbob7 on 7th Jul 2013 7:55am. Edited 1 time in total |

I insulated my footwells and battery box using a radhaz kit, certainly keeps the cold out not sure it would do much about sound deadening
I am wary of putting anything additional on the engine, for fear of it overheating Dynamatting is probably the answer for the cabin but be aware of the additional weight you are installing |

As I understand it, the rubber sheet glued to the panels helps stop vibration created noise,closed cell foam (which is what Rad-Haz kits are made from) helps stop noise penetration,wind noise,other traffic, etc.

A good source of knowledge for sound deadening a vehicle can be found here.

I know mines a Td5 but I cut out a lot of the heat transferred to the seatbox by a de-cat and taking the centre box out, mine used to.roast the passenger when pulling when towing up long hills. The spitting and crackling noises coming from the passenger seat were not exactly lady like

I would avoid noisekiller as the foam they use is open cell, which, whilst better at soundproofing than closed cell, retains water.
Dynamat is good for the vibration layer, as is Silent Coat, which is cheaper. |
