Just saw this. Apparently a Fluence owner is not happy with the rain noise on the roof of the car. And when he opened up the roof, he found that paper board is used for soundproofing the roof.

Does anyone have any idea if this is a "standard" practice in using this material for this particular model, whether the overseas model only used this paper board, or is it Renault Malaysia (or Tan Chong) that used this paper board for soundproofing?

Let's leave the opinion whether paper is good, average or bad soundproofing material, although I for one wouldn't be too pleased to see that being used for soundproofing.

Back to the question, does anyone know if this is "standard" practice in using this material for this particular Fluence model, whether the overseas model only used this paper board, or is it Renault Malaysia (or Tan Chong) that used this paper board for soundproofing?

Will never know... also depends... some japs model dont even have paper just bare steel...

Be thankful that Renault/TC didn't give you this 3M "soundproofing"

some might be suprised when they 1st know about corrugated paperboard used as automotive material, its can be found in many low end models mainly for interial purposes.

1. your sunvisor is made of corrugated paperboard taped to a piece wire frame, before wraped by pvc sleeve.
2. certain portion of the roof and boot is glued with the same material not only as sound absorbent but primarily as a filler agent between "headlining-and-panel" or "carpet-and-panel" in preventing the flapping noise.
3. you can find the corrugated plasticboard in 1st gen vios, where it seperates the rear seats with the car boot.
etc..

not the best soundproofing but it's cheap

You will likely get this in lower range or cheap Japanese cars, though you won't be seeing this in more premium continental cars. Surprising that they used paper boards rather than proper soundproofing sheets which won't cost much anyway. Might as well they don't put anything in the roof if they thought of using paper boards, but then they don't expect owners to open up the roof to have a peek.

Certainly doesn't look too good or "professional". More to a cutting-cost exercise that they have to resort to using paper board as a soundproofing medium? Don't think the difference will be too significant anyway when compared to bare (without anything in the roof).

I hate to say it, but even the Volkswagen Passat has the same sort of cardboard on the top of its roof. It's bigger though but still very disappointing when you see it.

maybe special kind of cardboard??

I've asked Megane owners on a German forum, maybe they can say something about how their car looks like.

But yeah, at least got sound proofing, compared to the Vios.

How do other cars look like? What material is used there?

Most of you might be surprised. Car manufacture will find way to cut cost. U think save RM500 for a car is little? If one month they can produce 500 cars that will be RM250k saving.
My previous company supply sealant to most car manufacture in Malaysia. Too bad they can't get into P1. The same sealant P2 used could be the same as your so call import cars.

RM 500? Huge savings. Car manufacturers would go for even smaller savings. I've even heard that for example the engines VW produces that go to Audi, VW, Skoda and Seat can be different despite supposedly being the same. The engines that go to Skoda and Seat may have less neat cable arrangements, cheaper cables, maybe higher manufacturing tolerances, or maybe parts that don't pass quality standards for Audi and VW go to Skoda and Seat. etc. Source is someone who IIRC has talked to someone working for VW.

Really? Have you seen it? Perhaps the CKD version here has skimped on some of the fine parts such as the soundproofing material.

The Volkswagen is not a really premium brand to begin with when compared to Mercedes and BMW.

To be frank, if car manufacturers chose to use cardboards as soundproofing material, they might as well don't put anything and just leave the roof or other parts of the car empty as it is. It's rather hilarious to see cardboards used as soundproofing when the raw material of the soundproofing isn't too costly. Maybe around RM100 thereabouts.

What if it works? I mean, yes, it rather cheap looking, but pragmatic. I haven't tried it, I haven't compared it, but what if it just simply works? What's wrong with it then?

You are not getting the point which is comprehensible judging from your previous silly posts. Anything works. Even if you use some old clothes or newspapers, you stuck those things in the roof of the car they will work. It's only the magnitude of difference will be rather insignificant.

Erm, that is obvious. I mean, maybe cardboard does work well. Maybe it isn't ordinary cardboard. Who knows. All we have is a low res photo of some material that looks like cardboard.
