Item(s):3M Thinsulate Automotive Acoustic Insulation Material (Sound Absorption)
Improve conversation & car audio quality by installing 3M Thinsulate in your car.

Package includes:
3M Thinsulate TAI-4047 (Thickness: 23mm, Weight: 420 g/m2, embossed surfaced on both sides)
*Thickness stated above is data provided by manufacturer under controlled conditions, actual thickness may be less due to compression.

3M Thinsulate is an excellent sound absorbing material (particularly on medium to high frequency, very effective in reducing wind noise) which has several advantages over other material.
1. Much better sound absorbing performance compared to other material like felt and Insuxxx/Superxxx.
2. Act as a thermal insulation material too (Good feature especially when you install it on the headliner / roof)
3. Light Weight (Less weight added).
4. Compressible (Can be installed in tight area like door trim, etc).
5. Will not absorb water (No need to worry about development of mildew & odour).
6. Easy to handle (Can be cut by using normal scissors & installed by using hot melt glue or double sided tape).
7. Pass Flammability Test FMVSS302, flammability = 0mm/minute




Sound absorption performance of the commonly used black colour material (Insuxxx)



FAQ:
1. Why closing down?
-Low demand due to less people doing DIY.

2. Why so cheap?
-Closing down, all items are selling below my cost.

3. Why courier fee so expensive?
-Not doing this business anymore. I have to purposely go to Poslaju, queue and post the item.

4. Is it genuine product?
-Yes, 110% money back guaranteed. The product is from 3M Malaysia Authorized Distributor (Automotive Division)

Depending on how you want to install it, normally:
4 doors need about 2m x 1.5m
Floor needs about 2.5m x 1.5m
Trunk/Boot needs about 1.5m x 1.5m
Fender liner & all the pillars need about 1m x 1.5m
*Generally, for casual DIY, you need 5m to DIY all 4 doors, floor, rear shelf, ABC pillars & fender liner.
*3M Thinsulate has the best result if installed behind door trim, ABC pillars trim, roof, rear shelf, fender liner & behind bonnet insulation.
*Put at least 2 layers of 3M Thinsulate if you want to install on floor to achieve satisfactory effect.
*You can stack 2 layers of 3M Thinsulate without adhesive to achieve thicker thickness if desired.
*3M Thinsulate has minimum effect if installed on boot.
*Do not install 3M Thinsulate where it will be exposed directly to engine heat or exposed in car cabin.


Basic Knowledge of Automotive Soundproofing

There are 2 types of noise:
1)Structure-borne noise (Noise that travels in vehicle structure)
2)Airborne noise (Noise that travels in air)

Example of structure borne noise:
Consider an running engine as a source of vibration. When an engine is running, the vibration will propagate over the whole car structure, such as roof, door panels, etc. The vibrating roof, door panels will transfer energy into air inside the car cabin, and then generate noise.

Example of airborne noise:
Consider an running engine as a source of noise. The noise will propagate through the air and get into cabin through holes or leakage and across the surface of car structure.

There are 4 major ways to soundproof your car:
1) Isolation - reduce transmission of vibration energy (Structure borne noise)
Eg: Engine mount, suspension bush,etc

2) Damping - dissipate vibration energy into heat (Structure borne noise)
Eg: Constrained Layer Damper (CLD) like STP Gold, Dynamat Xtreme, etc

3) Barrier - reduce transmission of sound energy (Airborne noise)
Eg: Mass Loaded Vinyl (MLV) like Dynamat Dynapad, CAE VB-4, etc

4) Absorption - dissipate sound energy into heat (Airborne noise)
Eg: 3M Thinsulate, STP Biplast, open-cell foam, etc

To effectively soundproof your car, you need to use different types of material to tackle the noise. 3M Thinsulate sold here is one of the noise absorption material. Depending on area of treatment, you will get better result by combining 3M Thinsulate with CLD or/and MLV.

A very common example:
You have put on CLD like STP iSilver all over your door, floor, and roof (close to 100% coverage). The car become quieter but you still can hear noise like wind noise. CLD only reduces vibration of car structure, hence reducing structure borne noise. Wind noise will still get into cabin through gap between doors, hollow car structure, tiny gap at door handle, etc. Wind noise will also get into cabin through windows due to its low sound transmission loss. However, we are unable to treat the glass. But you can treat the door area by putting a layer of sound absorbing material behind door panel to absorb the wind noise. You can also put a heavy layer of MLV (high sound transmission loss) to block the noise if you don't care about the extra weight added to the doors. Sound absorbing materials like 3M Thinsulate reduce echo by absorbing the sound. Hence, you will have a better car audio and conversation quality.

Tips: Have no luck in finding MLV in Malaysia due to low demand and low awareness on this material? Try to put (do not need to stick) a layer of CLD on top of 3M Thinsulate or PE foam, and you will get a more flexible alternative to MLV. The concept of using MLV to block noise is by putting a heavy layer (~1 lb/ft2, some are lower at 0.5 lb/ft2) MLV on top of a decoupler (usually PE foam or PU foam). CLD like STP Gold is about 0.7 lb/ft2. So you can put (do not need to stick) the STP Gold on top of 3M Thinsulate (as a decoupler) on floor or wheel arch to block tyre noise.

Bro, give pricing please. Interested buyer. Area kepong

Bro, price already being stated above. For loose quantity, u may WhatsApp me for detail. Thanks

bro after installation do i have to get my car approved by jpj?

Hi bro, no need. It is just like adding an accessory, not involving chassis, electrical or other major component. Just like a thing that make you more comfortable

HI..did u provide installation?

is it adhesive on 1 of the sides?

Hi, bro. Sorry for my late reply. Lowyat did not show notification...
Yes, I do provide installation, but only for certain car that I hv worked before like Persona n 1st gen Myvi, with charges depending on where to install. Pls whatsapps me if interested. Thanks

Hi bro, sorry for replying late as Lowyat did not show notification.
No, the material does not come with adhesive. You can use hot melt glue or double sided tape to stick it.
But if u able to cut it nicely, u can fix it on door panel without using any adhesive. And it wont drop due to its light weight.
Pls whatsapp me for faster reply if u are interested. Thanks

this issticky material or what material, if install on door, it stick or need other tools ?

This material don't hv adhesive.
You can use hot melt glue or double sided tape to stick it.
However, for some door panel(like myvi, refer to picture on first post), if you cut it nicely, you don't even hv to use adhesive.

hi can i buy only 3m 2047 and 1m 4047

Thank you for buying from me
Sorry for the late delivery

no prob. thanks for coming all the way even with the very bad traffic and non stop rain

here's a sample pic of my diy door panel. audio sounded better due to less noise from outside.
using thinsulate is a good way to block sound without adding too much weight to the car

Nice, bro Hope u enjoy the effect.
If u feel that the metal door is too thin (eg: Myvi), u can use a few damping material on the metal door, no need to cover all area. The effect will be better

Bro do u provide installation? Kindly pm me details

Bro, already PM you

Bro, I want this for a DIY project after CNY.

No problem bro. Just whatsapp me when you want it.

Bro, still available?
