Abstract

The main operational properties of the thermal and sound insulation material of the VTI-29 brand were studied, including: density, sound absorption coefficient, thermal conductivity coefficient, mass loss after 168 hours at a temperature of 70 °C, sorption humidity after 30 days at a temperature of 22±5 °C and relative air humidity φ = 98 %, residual combustion time and burnout length. It was established that the thermal and sound insulation material of the VTI-29 brand is comparable to Microlite AA blankets and ATM-1 materials, while in terms of density, sound absorption coefficient and sorption humidity, it surpasses them.
