I.G.P (Insulation Glass & Polycarbonate) is a type of window constructed from a layer of polycarbonate incorporated into the glass unit, which results in increased impact resistance, stable product quality, improved resistance to condensation, and reduced installation time.

Impact Resistance (Window Crack Prevention)
The external layer is constructed of polycarbonate resin panel, which has an impact strength that is more than 30-times stronger than tempered glass, providing an effective prevention of window cracking. The I.G.P glass shows particularly strong impact resistance against objects that impact from an angle.
Lightweight
Comparison of Car Window Weight
The polycarbonate resin panel is approximately 1/2 the weight of glass, enabling considerable weight reduction of the car.
Heat Insulation
Comparison of Overall Heat Transfer Resistance
(m2・K/W)
Constructed with the polycarbonate resin layer on the exterior, the thermal conductivity of the I.G.P windows is 1/4 that of glass. Additionally, the multi-layered construction provides exceptional resistance to overall heat transfer. Therefore, the I.G.P windows should reduce the need for heating during the winter period.

Noise Isolation
- 拡大
- Comparison of Sound Transmission Loss for Each Type Car Window
The combination of different materials (glass and polycarbonate) not only reduces the weight of the window, it also preserves noise isolation at a higher level than conventional windows.
Transparency (Weather Resistance Discoloration
A UV protective treatment is applied to the surface of the polycarbonate making it less likely to discolor compared to standard windows.
