Puruilsi Vehicle Aerogel Coating Retrofit in Shanxi: 8°C Temperature Drop and All-Season Comfort Verified

In April 2021, AG-C aerogel insulation and noise reduction coating was applied to Puruilsi vehicles in Xinzhou, Shanxi at 2mm thickness, covering the complete 30㎡ body surface with 45kg total dosage. Customer self-testing confirmed an 8°C reduction in interior-to-exterior temperature differential during summer operation, blocking external heat penetration through the body and significantly reducing cabin temperature without increased air conditioning load. In winter, the coating retained interior warmth effectively, maintaining comfortable cabin temperatures with lower heating energy input compared to the uncoated baseline. Road noise transmission through the body was also measurably reduced, improving acoustic comfort for both driver and passengers across highway and urban driving conditions. The straightforward 2mm application process shortened construction time significantly compared to conventional insulation retrofit approaches requiring panel removal. This combination of verified thermal performance, acoustic improvement, and installation efficiency positions AG-C aerogel coating as a practical, high-value solution for commercial vehicle modification projects with demanding performance targets and tight operational schedules.
