| titleOfInvention |
Spray foam building insulation for exterior applications |
| abstract |
An open cell polyurethane foam is provided which has a cell size and structure which allows the foam to act as an air and water barrier while still having acceptable water vapour permeability. The foam preferably is produced using water as a blowing agent, and includes a mixture of open cell-promoting, and closed-cell-promoting surfactants so as to provide an open cell foam structure having a cell size of about 1 μm, a density of about 1.05 lb per cubic foot, and wherein the cell structure includes randomly occurring solid walls on some cells. The open cell polyurethane foams of the present invention are suitable for use as insulation on the exterior surfaces of a building. |
