Insulating a Toyota Troop Carrier

A common problem with owning a robust off road truck is the NOISE! The cost of the engineering merit and capable drive line is compromise on expense elsewhere, particularly on creature comforts with basics in the noise and vibration department.



The common question from Troop Carrier owners we get is " How do I make this thing quiet?" I would like to carry on a normal conversation in the car without raising my voice"

There are 3 x products which are going to work to quieten the offensive road and mechanical noise created by the off road beast.


Step 1.
Stage 1 Sound Deadener is a peel and stick noise and vibration dampening mat. The best way to explain how this material works is to take a swimming pool. When you throw a pebble in the pool the energy of the pebble creates water ripples which carry on all the way to the perimeter of the pool.

Once we put a pool cover on the pool and throw a pebble in what happens? The energy of the impact is contained and doesn't have the same effect. 



Our Stage 1 sound dampening mats will have the same effect on your sheet metal where noise from drive line is effectively reduced and less on the comfort side.

Areas to cover in the Troop Carrier
Wheels arches - 3 x sheets per arch
Inner rear 1/4 panels - 3 x sheets per 1/4 panel
Inner skins of back doors - 2 x sheets per door
Roof skins between headers - 2 x sheets per roof section
Front floor pan to the top of the firewall - 20 x sheets
Front door skins - 2 x sheet per door on inner skin

Total = 7.2sq/m minimum


Step 2.
Mass Noise Liner is the alternative to peel and stick for those who want a removable solution. The material has a foam decoupling with a heavy weight mass loaded vinyl noise blocking layer. The product is designed to install foam side down and can easy be templated to floor shapes. The material is ideal for large flat areas such as the cargo area floor of the troop carrier. 



Mass Noise Liner is robust and does not require any glue. Not only is it the premium noise bloacking soloution it also offers great thermal insulation controlling those pesky heat issues.
Ideal for: Floor pans, firewalls (inside and out), boot areas, trucks, agricultural and industrial equipment
Not suitable for vertical mounting or roofs.



Areas to cover in the Troop Carrier
Rear cargo area 2 x sheets at 1500mm x 1000mm
Front floor pan and firewall 1 x sheet

Total = 4.5sq/m minimum


Step 2.
Insu-Layer is a 6mm closed cell foam which will reduce heat transfer and also create a soft surface which will reduce the rebound of acoustics in the cabin. The foam is 6mm thick and ideal for roofs with a high strength peel and stick backing.

Areas to cover in the Troop Carrier
Roof area 4 x sheets at 1200mm x 900mm

Total = 4.32sq/m minimum


So to wrap it up your going to need:

7.2sq/m of stage one sound deadener
3 x sheets of Mass Noise Liner
4 x sheets of Insu-Layer

Does it work

Whats the verdict? Any particular observations before and after?

Big Thank-You!

Thanks Guys for this informative Blog. I have a 2007 VDJ78R Troopy and was wondering how I could make the interior quieter and thermally insulated. Your page has given me food for thought!! Thanks Again. Anthony

This is exactly what

This is exactly what I was looking for. Thanks for wrgitni!

Plywood over Mass Noise Liner

13 February 2017
Hi guys, Great article, very informative - thank you. I am planning on laying some plywood boards as a flooring in the cargo area of my Troopy to use as a base to build a camper set-up (bed/cupboards etc) - I am just wondering if it would be possible / appropriate to do this over the top of the Mass Noise Liner? ie. can I screw the boards down into the metal sandwiching the Mass Noise Liner in between? Thanks for your time, I appreciate your help. Cheers, Dave

Rear Draws

Hi Is it worth putting mass noise liner if you have draws in the back? Cheers Terry Response
Hello Terry, if your draws are covering the bulk of your floor they may be offering some insulation. If you were to use our MNL as a blanket layer over the floor before putting your draws in yes it will help. Without seeing the configuration of the draws its hard to offer specific advice. Given this if you have any areas of the floor open where the draws don't cover they may be worth covering. The other thing to consider is the MNL will work as a decoupling layer if placed between the floor and draws. Muck like a rubber engine mount the material will work to absorb vibration which could carry through to the draws. Cheers Brendan
