What exactly is a Hood Insulator?
It is a custom-fit heat shield for your car. It is a specialized layer of material that sticks to the underside of your hood to handle the extreme temperatures and noise coming from your engine.
What is "Door Comfort" insulation?
"Door Comfort" involves adding high-quality sound-absorbing layers inside your car doors. Most standard cars have thin metal doors that act like hollow drums; this insulation fills that gap.
Why should I install hood insulator?
It serves three major purposes:
Saves Your Paint: Engine heat "cooks" your hood. An insulator prevents the paint from fading, cracking, or bubbling, which keeps your car looking new and holds its resale value.
Protects Parts: It keeps heat away from the sensitive plastic and rubber parts under the hood, so they don’t get brittle and break.
Dampen the Noise: It acts like a heavy blanket, soaking up the loud mechanical "clatter" of the engine for a more premium feel.

How does Door Comfort improve my driving?
Peace and Quiet: It blocks out the "whooshing" wind and tire noise from the road. You can finally have a conversation without raising your voice.
Less Stress: Constant road noise actually makes your brain tired. A quieter cabin helps you arrive at your destination feeling refreshed rather than exhausted.
Better Music: It stops your doors from rattling when you turn up the volume. Your bass will sound "punchy" and clear, making even a standard sound system feel like a high-end upgrade.

Are Hesovi products safe for my car?
Yes. Hesovi HeatPro is designed specifically for the automotive environment:
Heat Resistant: It can handle temperatures up to 104°C.
Safety First: The material is self-extinguishing (fire-resistant) and non-toxic.
Durable: It is 96% waterproof and won't rot or smell if it gets damp.
Can I use the same insulator for different car models?

Can I use the same insulator for different car models?
No. Each one is a "perfect fit" for a specific car. Hood insulator is like a custom-made smartphone case or a tailored suit.
Not a Flat Sheet: The underside of your hood isn't flat—it has a "skeleton" of metal braces and curves. Our insulators are specially molded to fit into those exact gaps like a puzzle piece.
Precision Cut: Every car model has a different length, width, and shape. To give you the best heat protection, the insulator must cover the hood perfectly from edge to edge.
Safety & Security: Because it is cut to fit your specific car's "bones," it stays firmly in place and won't sag or fall off, even with the constant vibration of driving.

Is it difficult to install?
Short Answer: Not at all! It is a "Plug-and-Play" project that almost anyone can do it.
The Simple Explanation: Installing a hood insulator is a (2/10) in difficulty.
Time Needed: 30 to 45 minutes.
The "Plug-and-Play" Process:
Use a simple tool (like a flat-head screwdriver) to take out the plastic clips holding your old, worn-out cover.
Clean Up: Wipe the area with a bit of soapy and clean water so the new piece has a fresh surface to stick to.
Align & Press: Line up the new insulator with the existing holes. It’s moulded to fit perfectly.
The Final Touch: Apply firm and even pressure to the entire surface of the insulator to ensure a strong bond or use a small roller to make sure it’s tight and secure.

Is it difficult to install Door Comfort?
The Simple Explanation: Installing door insulation is a 5/10 in difficulty.
It’s not "hard," but it requires patience. It takes more time and detail than the hood because you have to work inside the door panel. Expect to spend 1 to 2 hours depending on your car type.
What the Job Involves:
1. Remove the door panel: This involves finding and removing hidden screws, fasteners, and carefully prying plastic clips without breaking them.
2. Remove the vapor barrier: Peel off the plastic sheeting covering the inner workings.
3. Clean the metal : The inner and outer door skins must be surgically clean (free of oil, dust, or residue) for the adhesive to bond permanently.
4. Peel and stick : Peel and stick them onto the metal, and rolled them for maximum adhesion and damping performance.
5. Reassemble: Carefully put all internal wires, window controls, and the main door panel back together.

Who will fix the Hood and Door Insulator for my car?
1. For the Hood Insulator (Very Easy)
Since this is a "Plug-and-Play" part, you have three simple options:
Do It Yourself (DIY): It is as easy as changing a phone case. You just follow the manual provided and stick to the surface.
Any Local Workshop (Bengkel): Any general mechanic can do this for you in minutes. It doesn't require a specialist.
The Car Dealership: You can ask the service center to snap it on during your regular oil change service.
2. For Door Comfort (Moderate/Detailed)
Because this involves taking the inside of your door apart, it is best to go to:
Hesovi Heatpro itself : Our technicians are experts at removing door panels every day. They have the right tools to ensure no clips are broken and no plastic is scratched.
Specialized Soundproofing Centers: If you want a perfect, gap-free finish for the best audio quality, these specialists are the top choice.

Do I need to use clips to hold the insulator?
No, clips are not required because the sheet is self-adhesive (it has its own glue), but you can still use them if you want "double" security.
• Self-Gluing: The back of the sheet is covered in a strong adhesive. Once you peel the backing and press it onto the metal, it bonds firmly.
• The Secret is the "Pressure": To make it stay forever, you must apply even pressure across the whole sheet. Using a hand roller is the best way to "lock" the glue onto the metal surface.
• Optional Clips: If your car already has factory clip holes, you can still put the old clips back in for extra peace of mind or a cleaner "original" look, but the glue is what does the real work.

Is the glue strong enough?
This isn't ordinary glue. It is a specialized automotive adhesive built to handle the toughest conditions.
Heat-Proof: Most glues melt or peel when they get hot. This adhesive is made for the "engine heat cycle"—it stays aggressively sticky even when the sun is beating down on your car hood or roof.
Becomes "One" with the Metal: When you use a hand roller, the glue fills every tiny pore of the metal. It forms a permanent bond that won't vibrate loose or sag over time.
Rust Protection: Because the glue is waterproof and moisture-resistant, it acts like a seal. It prevents water from getting trapped against the metal, which actually helps prevent rust inside your doors.

Why is the product peeling or not sticking?
If it’s not sticking, it’s usually because of hidden dirt or uneven pressure during installation. The glue is very strong, but it can only stick to what it touches!
The 3 Main Reasons for Failure:
Invisible Dirt (The "Ghost" Layer): Even if the metal looks clean, it might have a layer of factory oil, wax, or dust. If you don't clean it properly, the glue sticks to the oil instead of the car.
Hand Pressure isn't Enough: Pressing with your fingers isn't strong enough. You must use a hand roller. The roller "forces" the glue into the tiny, microscopic pores of the metal to create a permanent lock.
Trapped Air Bubbles: If you don't roll it flat, tiny air bubbles get trapped inside. When your car sits in the hot sun, that air expands and "pushes" the insulator away from the metal.

Can I claim a new one if the product does not stick?
When a claim will be DENIED (Installation Errors):
Dirty Metal: If the back of your peeled insulator has dust, grey residue, or oil on it, it means the surface wasn't cleaned properly.
No Roller Used: If the "pattern" on the insulator is still perfect and flat, it shows that a hand roller was not used to "lock" the glue into the metal.
Improper Storage: If the product was left in a hot garage or under the sun for months before you tried to install it.
How to avoid a rejected claim: Before you install, take a quick photo of your cleaned metal surface and your hand roller. This proves you followed the correct steps!

How long will the insulator last?
It is designed to be a "one-and-done" upgrade that should last as long as you own your car. However, different parts of the car face different levels of stress.
The Simple Breakdown:
Door Insulators (15–20+ Years): These are the "VIPs." Because they are hidden inside your door panels, they are protected from the sun, rain, and engine heat. They usually last for the entire lifetime of the vehicle.
Hood Insulators (7–12 Years): The hood is a "war zone." It is constantly "cooking" from engine heat below and the sun above. While our materials are high-quality, years of extreme heat will eventually make any material less effective.
Our Recommendation:
Check it every 40,000 KM: Just like you check your engine oil and tires, give your hood insulator a quick look.
Signs it's time to change: If the material starts to feels brittle or hardened.

What will happen if I don’t change the insulator?
Over time, your car's comfort and protection will drop by about 10% to 15%.
The 3 Main Consequences:
Paint Damage (Hood): Without a healthy heat shield, the engine heat will directly "cook" your hood. This causes the paint to become dull, fade faster, or even start cracking (clear coat failure).
Increased Cabin Noise: As the material becomes hard or flaky, it loses its ability to soak up sound. You will start hearing more engine "clatter," road hum, and wind noise, making long drives more tiring.
Engine Heat Soak: A worn-out insulator can no longer manage heat effectively. This can cause the plastic and rubber parts in your engine bay (like clips, hoses, and wire covers) to become brittle and break much sooner than they should.

Does the product come with a warranty?
Yes, we provide a 1-year warranty, but it primarily covers "Factory Defects" (problems with the material itself), not mistakes made during installation.
The Simple Breakdown:
1-Year Coverage: We guarantee that the material will perform as promised. If the sheet itself has a visible manufacturing flaw when you open the box, you are covered.
The "Installation" Rule: Most warranty claims are rejected if the product peels off due to a DIY installation. Manufacturers usually attribute peeling to "Poor Surface Preparation" (not cleaning the metal or not using a roller).
Peace of Mind: High-quality insulators almost never fail if they are installed correctly. If you clean the surface until it’s "surgically clean" and use a hand roller, the bond is permanent, and you will likely never need to use the warranty.
