Rw Sound Insulation Index of IGUs

This guide explains the Rw sound insulation index, which measures how many decibels an insulating glass unit reduces airborne noise. It details the testing methodology and "single-number" rating defined by GOST 26602.3-2016 and GOST R 56769-2015. Soundproof glass manufactured by UNIALGLASS complies with these Russian national standards (GOST), which is absolutely mandatory for the Russian market. Certified compliance ensures accurate, verifiable noise reduction metrics.
