Note: Above data are for reference only. Specific product parameters require separate calculation.
Achieves 39 dB weighted sound insulation, significantly higher than standard insulating glass (approximately 28 dB).
U value as low as 0.48 W/(m·K), providing thermal performance exceeding 1.5m thick brick walls. Thermal insulation is 2-4 times better than insulating glass and 6-10 times better than single glass.
Eliminates internal condensation and fogging due to the absence of gas between glass panels.
