Beijing - Polyurethane foam insulation using Honeywell's Enovate blowing agent is helping to insulate China's National Olympic Stadium, said the blowing agent supplier, adding that this is "the first such use for a major public building in the region."
According to Honeywell, the technology will "help meet strict energy efficiency and environmental guidelines required by government construction authorities, as well as international Olympic construction guidelines regarding environmental protection."
The energy-efficient insulation is used on walls for seating areas for the National Stadium, commonly called the Bird's Nest. The Opening Ceremony of the 29th Summer Olympic Games will be held next August at the 2.8 million sq.ft facility, which will hold more than 90 000 spectators.
"Closed-cell spray foam insulation using Enovate is rapidly being adopted globally," said Ken Gayer, global business director for Honeywell's foam insulation blowing agents, in a company statement. "Honeywell is honoured that our technology will be a part of such a high-profile event like the upcoming Beijing Olympics."
Yantai Polyurethane Co. Ltd, based in Yantai, Shandong Province, supplied the polyurethane insulation materials, while Harbin Tianshuo Building Materials Industry Co. Ltd. is carrying out the spray construction.
The Bird's Nest is not the first major stadium to use this type of insulation, according to Honeywell.
