How to Use Aluminum Foil Sound Insulation to Absorb Heat?

Automobile noise can be roughly divided into four categories: engine noise, wind noise, tire noise, road noise, and resonance noise, due to the different parts and noise spectrum characteristics, of which engine noise is the noise generated by friction and vibration between parts after the engine starts. The not only noise but also generate a lot of heat, the noise and heat will be transmitted to the cabin through the hood, windshield and U-shaped sink and other parts, affecting the comfort of the car's occupants. In addition, the overheated temperature will also accelerate the aging of the sheet metal and paintwork.

Sound insulation and heat absorption

The protection of the hood is mainly based on sound insulation and heat absorption, not only to block the transmission of noise generated by the engine to the cabin but also to absorb the heat radiated from the engine to achieve the heat dissipation effect and prevent the aging of the cabin wiring and the hood paint.

Therefore, the ideal hood protection product should have many characteristics such as sound insulation, heat absorption, fire and flame retardant, anti-corrosion, waterproof, environmental protection and lightweight, etc. The surface is an aluminum foil layer, which adopts an open-hole aluminum foil structure, with dense perforations in the thin aluminum sheet layer.

Under the aluminum foil layer is the porous fiber structure of heat insulation cotton, with rich fibre space to form a natural heat insulation layer, the absorbed heat will be channelled, using the fibre structure of the cotton layer to absorb the heat, thus playing a very good insulation effect to protect the hood paint. In addition, after the hood is pasted with heat insulation cotton, it naturally constitutes a layer of sound insulation barrier. The sound waves of mechanical noise of engine operation will be reflected countless times after passing through the porous fibre layer of heat insulation cotton, and finally, the sound waves will be consumed, which is very effective in reducing engine noise.

Best Quality Aluminum Foil Heat Shielding for Automotive

1. Aluminum is thin and light. Today the car industry focuses more on reducing the weight of the whole car, thus aluminum which is a light material will be more beneficial to car producers.

2. The aluminum shield’s appearance has a positive aesthetic effect, thus it can increase the visual value of the whole car.

3. Our aluminum foil heat shielding for automotive applications is with low price.
