What are the types of automotive heat-insulating glass?
3 Answers
Automotive heat-insulating glass can be categorized into: 1. XRB1 glass: a phosphate absorption glass; 2. XRB3 glass: a silicate absorption glass; 3. Coated heat-insulating glass: a heat-blocking glass utilizing nano-powder coatings. Among these, XRB1 and XRB3 are suitable for use in high-intensity light conditions where heat needs to be blocked, while coated heat-insulating glass is more appropriate for architectural applications. The functions of heat-insulating glass include: 1. Filtering sunlight to reduce UV radiation harm to skin, with the capability to block UV transmission; 2. Maintaining thermal insulation inside the vehicle, ensuring air conditioning efficiency, and minimizing the impact of external temperature or sunlight on the interior climate.
As a car owner with over a decade of driving experience, I've specifically researched heat-insulating glass when choosing a car. There are mainly three types: heat-absorbing glass, heat-reflective glass, and Low-E glass. Heat-absorbing glass is ordinary glass with added iron elements, which absorbs heat but doesn't reflect light; heat-reflective glass has a metal coating on the surface, reflects strongly, and can show rainbow colors under strong sunlight; Low-E glass has a multi-layer design using low-emissivity technology, offering the best heat insulation. I've used a car with heat-reflective glass, and the interior temperature was noticeably lower in summer, reducing the need for constant air conditioning, saving fuel and increasing comfort. The downside is that the coating can get scratched and requires regular maintenance. Nowadays, many high-end cars come with Low-E glass—it's more expensive but a worthwhile investment. For driving, especially long trips, heat-insulating glass makes the journey more comfortable and protects the dashboard from sun damage.
From my professional experience, automotive heat-insulating glass can be categorized into three types: heat-absorbing, reflective, and Low-E glass. Heat-absorbing glass incorporates iron ions and other components to absorb infrared heat; heat-reflective glass relies on a metallic coating on the surface to reflect heat, commonly found in SUV models; Low-E glass uses multiple layers of film to minimize radiant heat transfer. These types of glass significantly reduce interior temperatures during hot summers, decrease air conditioning usage, and extend the lifespan of the car's AC system. In daily use, it's important to avoid wiping with cloths containing sand particles to prevent damage to the coatings. Additionally, heat-insulating glass blocks UV rays to protect the skin, and over time, it can save a considerable amount on fuel costs, offering high cost-effectiveness. For families on road trips, the improvement in comfort is substantial.
