The Pacific Science Center 1,900 m2 exhibit hall in Seattle (USA) has been re-insulated to improve temperature control and energy efficiency, using sprayed HFC blown polyurethane foam. Hitherto, visitors were enduring cold temperatures during the winter, and in the summer the buildings couldnt be cooled sufficiently.
The spray HFC foam was the best possible insulation solution for the building as it could be installed over the existing insulation and wall structure.
With only 7.5 cm of sprayed HFC-based foam insulation on the walls and 10 cm on the 11 m high ceiling, the building achieved a 90 percent improvement in energy costs.
