“Scorching summer heat” is a common phrase in Hanoi. Driving can be unbearable without proper car insulation, especially for the roof. Roof insulation is crucial for protecting your health and your car’s interior.

Why Insulate Your Car Roof?

Nguyen Van A, a car technician expert at XE TẢI HÀ NỘI, explains: “The car roof directly absorbs sunlight, significantly increasing the interior temperature. This not only causes discomfort and fatigue but also reduces air conditioning efficiency, consumes more fuel, and damages the interior.”

Benefits of Car Roof Insulation:

Reduces Interior Temperature: Blocks heat from the roof, keeping the car cooler, especially during summer.
Saves Fuel: Reduces strain on the AC system, leading to better fuel economy.
Protects the Interior: Limits UV ray and heat damage, preserving the car’s interior and extending its lifespan.
Enhances Aesthetics: Some insulation materials can also improve the car’s interior appearance.

Common Car Roof Insulation Methods

Several car roof insulation methods are available. Here are some popular and effective options:

1. Applying Window Tint Film

This is the most common method due to its convenience, affordability, and effectiveness. Various tint films are available, from clear to reflective, offering different levels of heat and UV protection.

2. Spraying PU Foam Insulation

This method involves spraying PU foam directly onto the car roof, creating an effective heat and sound insulation layer. It offers excellent insulation and durability but is generally more expensive than window tint film.

3. Installing Insulated Roof Liners

Insulated roof liners have a built-in insulation layer that prevents heat from transferring into the cabin. They offer a clean look and are easy to clean, but installation can be quite expensive.

Method	Estimated Price (VNĐ)
Window Tint Film	1,000,000 – 5,000,000

Budget: Each method has different costs; choose one that fits your budget.
