A residential building project in Salida, Colorado, has been retrofitted with Bayseal closed cell insulating foam, giving more than 50 percent energy savings over comparable structures, says Bayer MaterialScience.
Using BaySystems spray polyurethane foam, the local housing authority has dramatically improved the buildings' energy efficiency -- as part of a federal stimulus grant.
Two buildings were retrofitted with a closed-cell foam that BMS says "seals the building envelope to create an optimal energy-efficient environment."
Extreme Foam, based in Buena Vista, Colorado, applied the Bayseal CC foam to the bottom of the roof decks, creating an unvented attic assembly.
"Many of our tenants have been telling us how much better their living environment is since the buildings were retrofitted with Bayseal CC foam," said Billie Jean Valdez, executive director, City of Salida Housing Authority.
Extreme Foam is analysing the energy consumption of the two insulated buildings and comparing the results to those of two other buildings of the same size and footprint that haven't been retrofitted.
The buildings retrofitted with PU foam are achieving energy savings of 57-64 percent over the other units, Valdez said, adding: "These are senior-citizen housing units, and the tenants are more sensitive to temperature changes, which can impact energy consumption during any season."
