Do weather conditions influence the application of foam inside buildings?

Yes, both temperature and humidity have an impact on the application of foam inside buildings, e.g.: - too low outside temperature may result in chilling the place right after spraying, leading to foam shrinkage, - heavy rain increase humidity inside rooms where foam is sprayed, - too high temperature may heat up the sheet or surface where foam should be applied, which may result in improper thickness of foam and deformed structure.
