What kind of insulation hood to buy? Heater under the hood foil: reviews

In the autumn the weather spoiled motorists with warmth. However, ahead of winter with its unpredictability. Strong frosts at night - this is a normal situation. Many car owners often and often travel around the city, and the car remains in the frost for several hours. When drivers return for cars, the engine cools down completely and it must be warmed up every time. But you can fix this situation and get a hood insulation. It will not allow the engine to cool down so quickly.

Why is it necessary to warm the motor?

Many people do not notice how hard the cold engine starts. But on the resource of the unit such starts impose their imprint. So, at low temperatures overboard properties of motor oils, and also of fuel change.

Thickened with cold in the cold, it is not so effective that it penetrates into hard-to-reach points. If the motor does not get enough lubricant for a while, it will affect its stability. So, especially in this case the piston group and cylinders will suffer. With oil starvation, pistons work practically in dry conditions. Do not try to save on warming. Then you can strongly regret it. So, the insulation of the hood "Lanos" will cost the car owner only 1000 rubles with clips. It's cheap, compared to a major engine repair.

Fuel on a cold and frosty day also changes its properties. It evaporates worse, and this does not have the best effect on the quality of the fuel mixture. The battery in the winter worse gives a charge. The engine starts much heavier, even with a special winter oil.

And what about the regular hood insulation?

It is worth saying that in the conditions of the Russian winter, the possibilities of this material are clearly not enough. It is effective at temperatures down to -10 degrees. Therefore, it is necessary to select an appropriate insulation material for the winter.

A more serious standard insulation is installed on those cars that are sold to the northern latitudes. The rest of the machines have no additional means. Often motorists insulate the car on their own.

Insulation of the hood: what to choose?

Many owners try to solve this popular problem with the help of what came to hand. So, it can be a blanket or felt. Felt is excellent, but a big piece is sometimes difficult to get, and it's difficult to sew it. Naturally, to some extent this helps, but it is also not very effective.

There are more quality professional materials and products for these purposes. For each specific brand, special kits are produced. Among the main advantages of such professional solutions is easier fixing and dismantling. Such products are produced in small batches, and small private producers are engaged in them. If you need just such a professional option, then it is rather difficult to buy it.

In such centers offer two types of insulation. Either it will only be the hood and the engine compartment, or the entire car. It is very expensive and difficult to warm the car completely. Therefore, most car owners prefer to simply telposistolirovat engine with their own hands.

Manufacturers

There are only a few manufacturers that supply the heater to the hood. This is the company "Standard-Plast", "Standard" and "Hermes". Behind these manufacturers remains an excellent reputation. Numerous reviews are all positive.

The company "Standard" is ready to offer a technological insulating hood "Isoflex" and "Tiwiplex".

"TiwiplenP" has a self-adhesive layer, and it is made on the basis of polyethylene foam. These are three layers - a layer of glue, directly foam plastic and the front side of PVC. There are no foils in this product, but the heat is kept quite efficiently. You can choose from several types of products in terms of thickness. You can choose a thickness from four to fifteen millimeters.

As for "Izoflex", it is more sound-absorbing and does not suit for keeping heat. However, due to the layer of polyurethane foam can be used as a heater hood.

Producer "Standard-Plast" offers only thermal insulation products. At this enterprise initially went to the creation of universal solutions. The products not only perfectly maintain heat, but also have excellent noise-absorbing properties.

Auto Blanket

Such a heater under the hood can be easily found in stores. The choice of models is huge. But with the availability of skills and materials, such a blanket is easily made by hand.

The blanket has a special structure on the basis of special mullitokremnezemistoy cotton wool. Also there are models with filler made of fiberglass. Fiberglass can be found in a fireproof panel. With the help of this material, industrial gas and oil pipelines are insulated. This heater has a low thermal conductivity and does not burn. Fiberglass easily can withstand high temperatures and stand against the impact of various technical substances and liquids.

This product can reduce the warm-up time of the car from 15 minutes to 5. In addition, the heat will be saved. With short stops with this product, the machine will not cool down. Blankets have a high cost, but saving here is to lose in efficiency.

We warm the hood

Auto-blanket is perfect for engine protection. But what if I need a heater under the hood?

Many recommend using foamed polypropylene. It can be easily found in building stores. It perfectly keeps heat and reliably protects the engine compartment from the cold.

This material does not break even at very high temperatures, so it is almost the ideal choice for a car. As for the thickness, the most optimal size is 20 mm. You can make a heater with your own hands. It is necessary to cut out the necessary piece so that it maximally repeats the shape and surface of the hood of your car. Secure the material with special clips. A piece of material for processing the stiffeners is also required.

It is worth noting

An important point - before gluing the insulation layer should be thoroughly washed and degreased the back side of the bonnet. This is a guarantee that the material will not fall off suddenly when driving or at another inopportune moment.

Now the engine will not be afraid of even the most terrible frosts. You can use the machine without fear that the engine will cool down. Another advantage is the complete absence of ice or ice on the hood. At the same time it is available. Foil insulation, the price of which in building stores is very low, practically not inferior to professional blankets and other materials.

Comparisons and tests

Tests of various heaters were carried out. So, among themselves competed factory products, foamed penofol, and also a blanket and a felt. Outside the competition, the bonnet heat lighter "Lanosa" was also tested, which showed the average result. The results were taken after three experiments. Thus, the time of heating the unit to operating temperatures, the time for complete cooling, and the danger of ignition were measured.

The temperature at the time of the tests was about -20 degrees. Within 10 minutes the machine was warmed up with a heater and without it.

As a result, with the auto-blanket engine completely cooled down for 6 hours. A regular hood insulation showed the result at 4 o'clock. Isolon with foil took the honorable third place with a result of 3.5 hours. And at all without a heater the engine completely cooled down for 3 hours.

Felt was in a separate standings - its result is 5 hours.

If we talk about the danger of ignition, then the maximum result is only for an auto-suit. Foil insulation, the price of which is very low (200 rubles), can be expensive for the owner. In case of a short circuit, if the foil touches the terminals of the battery, the material flashes almost instantly.

Conclusion

That's so easy and inexpensive you can prepare for the winter, which in our country always comes suddenly. It is not necessary to wait, but it is better to purchase the necessary materials in advance, make patterns or use a factory or factory decision. This allows to improve the efficiency of power units in cold and frosty winter. With heat insulation, the motor will improve, fuel consumption will be at the level of autumn. The unit will operate in sparing modes, which will remove the need for overhaul.

So, we figured out how to choose the right insulation for the hood for the vehicle.
