Hi Gasket,
Lots of differing points of view on here, but mainly based around what your expected usage is. If you plan to spend most of the time on-road, therefore not suffer from excessive water/dirt in the foot-wells that needs to be drained or washed out, then a full soundproof is your option. If you do plan to do a lot of off-roading, then only part soundproofing is recommended. Basically you have three or four layers that you use as you see fit. Base layer is Dynamat/Noise Killer/Silent Coat. Again, there are differing POVs here. Some feel it only stops rattles (which it does brilliantly well) but does not have an impact on sound-deadening/transfer, so therefore only a sheet or two is needed per panel, not a full layer. Others argue that a thick, dense material layered on top of flat metal will stop some sound coming through, so cover all key areas such as the floor pans, walls and roof. I’m of the latter opinion, so did the whole lot (including inside the doors) with silent coat. Next layer is the deadening foam, for example Dodomat, available from the same supplier. Some deadening has adhesive backing (for use on the roof, vertical areas such as van walls or the front edge of the footwell etc) and some is extra dense/HD and cut to shape before being layered in areas such as the middle floor well or load area. In the roof, you can use this foam as well, or alternatively you can use an adhesive backed egg-carton type foam. Be aware that there’s limited space under the headlining. The HD foam stops sound ingress and also ‘dampens’ sound from within the cabin, such as music or talking. As such, you use the deadening accordingly. The final layer is your choice of matting/headlining/trim. If you plan to drive mainly on the road, then carpet is obviously the go-to covering, perhaps with rubber mats in the foot-wells/load area for cleanliness. If you plan to do a lot of off roading, then clearly rubber matting is the order of the day. For the headlining, Alcantara does dampen the cabin further. Interestingly, I think psychologically a dark headlining also makes the cabin feel more intimate (quiet?). Some people will also add alcantara/leather trim to the dash, door cards, trim etc, which also help dampen sound a little bit. Note that some aftermarket carpet, such as Exmoor Trim’s, comes with the deadening already applied to the under layer. Obviously this will double the thickness of material on your floor if you add it on top of the deadening sheets. No bad thing, but it can create problems with trim, metal carpet strips, door closing etc. So check before buying/applying. Finally, it’s worth remembering where the sound comes from and what else can be done. Roof. A lot comes through the roof, so do it properly. A-pillar. Nothing you can do Door seals. Lots of ‘whistling’ through door seals, so makes sure they’re in good nick, but also make sure your doors are properly aligned and close properly. Floor pan. Only a few mm of metal between the cabin and the road. Do these properly. Front foot-well. Lots of noise comes from this area, so dampening/proof it well. Carpet will improve it further, as will quieter and more road-biased tyres. Clearly this is the same for the rear wheel arches. Bulkhead. Difficult area this. Obviously if you plan to take the engine out for any reason, you can make some improvements to the other side. However inside it is limited. You can put some behind the dash and at the top of the footwell, but not that much. Transmission tunnel. Can be noisy, especially in a 2.4, so as much as possible under the cubby, around the gear box cover, etc. Carpet does make a difference here, and there is an argument that a better clutch (which I saw in another thread you’ve added) will help as there will be less rattle, as will a remap as it will reduce and smooth out the revs. Sound system. Finally it’s worth bearing in mind that after you’ve dampened/proofed an improved sound system will cancel out (Not block) the final ingress of sound and allow you to enjoy your music/audio books more. Anyway, as you can see, with so much to do there are many options and variants, as there are also many opinions. What you do will be governed initially by primary usage, then money, then time/effort. If you do a full job, DIY, a 90 could take a weekend, but it’s worth it. Finally, here is the go-to shop. If you mention what vehicle you have, they will recommend the kit/amount you need. Excellent service, excellent price. https://www.deadening.co.uk/ Good luck Monsieur Le Grenadier I've not been everywhere, but it's on my list..... 2011 Puma 110DC - Corris Grey |

Gwyn Lewis mud shields help a great deal to reducing crap hitting the rear underside of seat boxes behind the rear wheels. Cheers

Rambling thoughts:
Probably worth thinking about serviceability as well. I chose a Wright off Road design which is easily removed to access floor, footwells and seat box for mods and maintenance. If it gets wet through off road use, rain ingress and condensation (the last 2 definitely) is the system designed to dry out or will it lock in the damp and accelerate rot?

I have the full Noisekiller kit fitted including seat box, rear floor / arches, sides and roof. I can't comment on the difference with and without as it was already fitted when I bought the LR but it is certainly quieter than the standard LRs at work.
The material is pretty sturdy and easy to wipe down but does have a few rips from dragging heavy tool boxes and the like over it in the load area. The only real complaint is it holds water like a sponge and despite best efforts at sealing the body gaps, the rear floor and footwells are always wet under the material. 2005 Td5 110 Hardtop 1989 300Tdi 90 Soft top 1992 200Tdi 90 Truck cab with Land Cruiser axles |

Gents thank you for this.
So it looks like the best course of action is: WrightOffroad acoustic matting kit in the front and a load liner in the back. That way water isn’t an issue. And then a conversation with NoiseKiller to get a part kit to cover all the other areas including the bulkhead parts that aren’t covered by the acoustic matting kit. The Puma acoustic matting Kits seem to be thin on the ground at the moment, so there may be a supply shortfall. |

My Wright off road mats arrived today, a quick trail fit and they look good, just need some time to fit the seat box mat properly, but initial thoughts are good. 80" 1948

Spot on! Are yours for a Puma? If so could I ask where you got them as post places seem out of stock.

Thanks - I've just called them direct.
Right - have just spoken to Wright off road, placed my order and my kit is being made. Have gone for a full front set and a flat sheet for the back to replace the thin factory mat. All being made in black, so should be quite subtle. I'll speak with Noisekiller too to see if they can put a kit together for me to cover everything left exposed by the Wright kit. |

Hi Gasket - did you fit the Wright off road stuff?
Any pics/thoughts would be appreciated. Rgds. Chris |

Theres quite a lead time on Wright matting kits at the moment due to covid, as a result they are quoting 6-8 weeks wait. I'm 7 weeks in

Hi both - its on order and should arrive mid-december.
Mo - I'd love to see how you get on when it comes to fitting as yours will arrive long before mine. I'm still trying to work out how the mat will fit in conjunction with/instead of the bulkhead padding sheet. (mine's pretty ropey along the footwell overhang so if I can lose it I'll be happy) |
