Aerogel Felt And The Beijing Winter Olympics

Maybe you only pay attention to the Winter Olympics

Not paying attention to the venues hosting the Winter Olympics

In the speed skating hall known as the "Ice Ribbon", a green "black technology" - aerogel felt, is silently contributing to the "insulation" of the Winter Olympic venues.

The speed skating hall, known as the "Ice Ribbon", is the iconic venue in the main competition area of the Beijing Winter Olympics in 2022 and the only new ice competition venue. The temperature difference inside and outside the venue puts forward higher requirements for the thermal insulation system of the venue. A green "black technology" - aerogel felt is used in roofing systems and curved curtain wall systems.

Aerogels are the lightest known solids in the world and significantly outperform conventional materials in their thermal insulation capabilities. The thermal conductivity of aerogel composites can be as low as 0.017w/(m·k). In view of the thermal insulation problem of the curtain wall, aerogel is used to block heat transfer, reduce the K value of the curtain wall, and reduce the risk of condensation. At the same time, blocking the cold bridge effectively reduces unnecessary energy consumption caused by heat exchange, improves energy utilization, and reduces carbon emissions.

In layman's terms, sitting in the speed skating hall, the winter sunshine illuminates everyone through the "ice ribbon". However, the heat brought by the accompanying sunlight makes the speed skating hall "melt with ice and fire". The products made of aerogel felt as raw materials are applied to the stadium, which can effectively block the heat from outside and keep the needs inside the stadium. temperature reached.
