Abstract: Efficient thermal insulation is becoming increasingly important as people spend more time in buildings. Aerogel blankets are highly porous materials made of polymeric fibers coated with aerogel particles that are used for building insulation. This paper aimed to explore the effect of moisture on the thermal properties of insulating aerogel blankets, because in humid environments, condensation within building insulation heightens thermal conductivity. The thermal constants analyzer TPS measured the thermal conductivity of aerogel blankets using the transient plane source (TPS) method. Results showed that thermal conductivity increased over time, and reached its maximum capacity after six cycles between 0% and 80% relative humidity.
