Re-create a Factory Under Bonnet Look. Premium Under Bonnet Insulation Pad Material Liner

Just installed this toady one underside of my hatches removable parcel shelf. Works a treat

[@carbuilders1]

Well done 👍

My box of under bonnet arrived today. What a great company to do a cool vid on how to, if not i probably would have destroyed the job. Thanks guys.

Seems harder than it needs to be, but you only have one chance to do it right. Excellent result.

[@Jeenzy79]

Awesome! I’ve used the car builders stuff to sound great and insulate the roof of my car, it’s amazing. I’ll be painting a new bonnet soon for my car as well, definitely going to use some of this stuff as well!

[@_J.P._]

Like many others: no before and after sound comparison. Which is the foremost reason I am looking for such videos. But I like the workspace :) nevermind, moving onto the next one hoping for some sound comparison.

[@carbuilders1]

Thank you John. We often put sound comparisons in our install videos. However, in our efforts to be totally transparent, we have always felt compromised when doing this. There are so many variables in trying to give an accurate decibel analysis. The vehicle and its age, the model, the motor, modifications, tyres, road, weather, decibel frequency tested.. the list goes on. Please be careful when presented with decibel before and afters. We will have videos out shortly where we test each material (for sound or heat) in controlled situations. Good luck in your search 😎👍

[@ausguy4385]

@@carbuilders1 make a lab size sound proof box with two halfs with the material placed in the center. Sound one side, meter the other. Only change the material. Bingo will see material comparison. Just need a real decibal meter, A exhaust shop will have one to borrow or tell you where to source one. Then all you need is sound thats repeatable. A car head unit with speaker and sub would give a good repeatable sound across the Sound spectrum. Sorry but a sound proofing company without even a real decibel meter is laughable 🤦‍♂️

I helped to install a headliner in my brothers truck, and I used a monokote iron for rc airplane wings, controll surfaces, and fuselage to get the roll on headliner with adhesive to form into the creases and around contoura. The iron comes with cloth covers to use while ironing to prevent Burns and the iron does not use steam. It only uses heat. It seems like on this material that type iron would work well to install the bonet material also.

Interesting, I don't have a heat gun, but have one of these irons I never use 🤔👍🏻

Hi. The product looks awesome. Although two questions. How good this will be in long run, as standalone under hood insulation? I am planning to replace worn out foam insulation in my w124 and want a standalone product that is not foam like the oe , as with time it tends to crack and fall in small pieces inside bay. Secondly the goal is to mainly reduce diesel clatter noise both inside and outside of car. Thanks

[@carbuilders1]

Hi Mayur. Thank you. Yes, this product is a lot more durable than a manufacturer's foam insulation and will last much longer. This insulation will protect the bonnet paint from heat fatigue and also provide some sound insulation .

[@clark57225]

Great question, that's exactly what I wanted to know for my 300E.

[@alexbrown1995]

Very good production. Wish I'd known about this method and material before I put dynamat under the bonnet of my GU. That looks a lot better. How good is it in heat proofing, though?

[@carbuilders1]

Thank you. Yes, Dynamat (or our Sound Deadener) primary purpose is to stop panel vibration. It will make a very small difference with heat but not significant and you will want to cover it and not expose it to extreme temperatures in the engine bay. If you don't have the factory cover over it you could look at something like www.carbuilders.com.au/premium-under-bonnet or if heat is a big issue, a more extreme treatment would be www.carbuilders.com.au/peel-stick-heat-shield 👍

[@Crusty_Camper]

Is this available in the UK? It's just what I am looking for.

[@pabllok]

Great tutorial. What would you recommend to reduce vibration in old diesel without dual mass flywheel? I feel vibration throughout the seat, caming from the floor. I have already deadened the firewall with butyl mat and foam mat on it. Now I'm gonna put something on the floor, the target is to reduce vibrations, noise is not so big problem. Thanks you in advance.

[@carbuilders1]

Thank you. If your vibration is that significant you should look at alternatives in more efficient engine mounts or even suspension cushion seats.

[@smportis]

Or balance the flywheel at a machine shop

[@franktheodore9773]

What if you don’t have the original insulation to trace? Predicament I’m in with a 1970 Mercury Cougar.

[@carbuilders1]

Making templates can be dangerous as it is hard to account for rises and falls in the surface which change the amount of material required (in the video we only used it to make a rough oversized guide). If you lay the sheet on the bonnet/hood first and allow it to be evenly oversided. Then reveal some of the backing on one of the edges of the bonnet and continue from there to stick it down. You will have extra over each side that you will then blade off (careful not to score the paint- as in video) 👍

[@truthseeker8483]

Top Tip...Don't try and take the bonnet off by yourself......also some Dynamat under the insulation pad works well.....

[@carbuilders1]

Shout a mate a couple of beers for this one 👍 In other videos you can see we have place our deadening mats underneath. A win with the Defender is the bonnet angles all the way back to the windscreen so you can install without removing the bonnet.​

[@MahiSingh-gt5sy]

hi interesting ,i want to ask some technical detail that should be in the material used for this purpose, like what properties it should have

[@carbuilders1]

Hi Mahi. There are cheaper foams that replace the factory underbonnet however, like the manufacturers version, the foam ends up failing and flaking. This product is a textile material, which is more durable. As you can see from the video, we wanted to manufacture a product that looked factory pressed however was able to be applied to a universal bonnet. We want a durable product that could withstand a high pressure hose and was fire retardant. The material is also a dense needle punched fabric, which will help reduce heat transfer and filter sound waves.

[@MahiSingh-gt5sy]

thanks for reply can we use the black Blankets used by Army around the world, for the same purpose as it is fireproof and dence, asking for its thermostat properties, is this good or bad for bonnet, or depends on how we install under bonnet, to not to allow heat to tranfer to the layer with direct contact with bonnet, just a query on experimenting ideas!

Hi Ryan. Yes, this is fine under the bonnet. You don't need to load it up, just add squares in open, single sheet panel sections and then put the Premium Under Bonnet over the top 👍

[@secpac58chichi]

I can go with either a foam insulation pad or a fiberglass pad - do you have an opinion on which performs best ? MBZ use foam on $100K cars but I suppose that doesn't mean anything - my original was destroyed by deer mice as they liked the insulation material - do they like foam or FG ? thanks

[@carbuilders1]

Our premium under bonnet is a superior product as it isn't a foam but a needle punched polyster. Both will function similiarly, however the material is more durable and puncture resistant than foam.... also I think deer mice detest it 😆

[@danielkrupski7471]

I don’t understand? All you did was replace it. The original didn’t look like it was in bad shape. For some reason replacing an oem with your product helped how? Sound/ heat?

[@carbuilders1]

Hi Daniel. Yes, you right, that underbonnet pad was fine, we just used it as a model. You wouldn't do this because, as you have pointed out, it isn't necessary. These pads break down over time, 20 years etc and people find them hard or expensive to replace and this is when this product is used. They are also a durable-faced product so they have advantages there over many OEM versions.

[@LaNoches]

Very nice job and great explanation! I stumbled upon this video as I was looking to do the same to my Skoda Octavia MKIII 2017 facelift as I found it to be noise 2000+ rpm (diesel)... Turns out the insulation Skoda put in place (with clips) is actually the culprit! Would removing it hurt my engine in any way? And secondly, would adding insulation like you did provide noticeable improvements? Thanks!

[@carbuilders1]

Thank you. Was the bonnet insulation rattling? Apart from adding some sound insulation, if you remove it you will expose the bonnet to greater heat and potentially paint fatigue. If the factory insulation is in good condition you may look to replace the existing clips as an easy fix. 👍

[@LaNoches]

It seems easier to flip the old one and use the new material on the backside and drill some holes the using the old front of the bonet hood insulator as template for the holes and then reinstall but with new bont material on the outside.

Insufficient method to address engine noise although its a critical Step 1 in reducing engine noise intrusion. The most IMPORTANT area giving the BIGGEST reduction in engine noise intrusion (besides firewall) is the area/narrow gap behind your door hinges. KIA and Hyundai hv become impressively quieter due to focus on this critical area. Look at the Hyundai Santa Fe..and you’ll see “something” there put by the manufacturers. In contrast, look at the Merc A Class (noisy engine noise and loads of tyre noise). There is NOTHING there (when u open driver door and peep behind the door hinges) except a thin black plastic cover. Look at the narrow area BEHIND your upper and lower door hinges. Thats where engine noise and tyre noise penetrate into the cabin. Its actually a hollow space that leads to the inside of the fender well cavity. Remove the wheel well liner. Stuff loads of waterproof, non fraying noise absorbent material into that empty area. Rolled up or folded up Thinsulate is best. In any non-Continental vehicles, treating this area produces a significantly impressive reduction in engine and tyre noise WITHOUT doing anything else.
