STRUGGLING TO HEAR YOUR FAVOURITE TALKBACK PROGRAM? THEN TURN YOUR TROOPY’S INTERIOR INTO A SOUNDPROOF UTOPIA.
TROOP CARRIERS are commercial 4x4s, not luxo-barges, so it’s to be expected that they will lack some mod-cons, one of which is interior sound deadening.
Unfortunately, my Troopy suffered more than most. Having been an ambulance in a previous life, they seemingly drilled, cut and hacked more holes in it than you could poke a stick at. These floorpan holes allowed tyre, driveline and road noise into the cabin and eliminated the ability to talk to passengers or listen to the radio, no matter how high it was turned up. It was downright annoying.
My first step was to spend up on rubber grommets to fill as many regular round holes as possible, while a few conveyorbelt-type rubber patches with liquid nails were used to patch the larger misshapen hack-jobs. While that approach may seem a little antiquated, it was the most straightforward and effective first line of defence to prevent the ingress of noise.
Next up, I called Tru-fit Carpets in Melbourne to discuss my options. On their advice, I went more high-tech, with the purchase of a couple of boxes of Resomat. Resomat is a premium heat reflector and sound deadener that incorporates a sticky back, a thin rubber layer, and a top silver heat-reflective surface layer, which should rid the heat sink problems from the exhaust system that is positioned close to the floor on the passenger side.
The Resomat helps to deaden noise, stop vibration and, as noted, reflect heat. This product is also used in door skins to help control panel vibration from stereo speakers, but I have no need for that.
Once positioned, the Resomat backing is peeled off to allow moulding to the floor panels – and while a small roller is advertised as being the best way to apply it, I simply pushed my thumbs and a rag over it to ensure good fit and adhesion (no heating is required).
Thankfully, the product is odourless
The Resomat comes in 3.5m² boxed packages. Plenty of holes were exposed once the ambulance flooring was removed.
