heat insulation PVB Film Interlayer
What is heat insulation PVB film?
The heat-insulating PVB film is obtained by adding reflective infrared material to the ordinary PVB.
The ordinary PVB film can block 20%-30% of the infrared ray, heat insulation PVB can block 70%-75% of the infrared ray.
Our heat insulation PVB film is light blue, the visible light penetration ratio is 72%, and the haze is 0.45.

Application on Automobile
It can block 99% of ultraviolet rays and 75% of infrared rays when adopting heat-insulated PVB film on windshields.
Reduce fuel consumption
The use of insulated PVB film can reduce air conditioning work by 10%-15%, resulting in savings in fuel costs.
Comfortable
It will be too hot to bear when parked for a period of time and then enter the car again in summer, the use of heat-insulated PVB film can keep the car cool.
Prolong the life of automobile automotive upholstery
Light and high temperature are the main reasons for the aging of automobile automotive upholstery and the use of heat insulating glass can slow down the process.
Anti-ultraviolet radiation
The use of heat-insulated PVB film can block up to 99% of ultraviolet radiation, providing an effect similar to that of SPF 50 + sunscreen.
Application on Architecture
Energy-Saving
Heat insulating glass blocks 75% of the infrared ray, reducing the use of air conditioners.
Anti-dazzling and privacy
Reduce eye discomfort caused by glare; Insulating glass reflects light, making it difficult to see indoors or outside;
