Spray foam insulation is a great way to keep your home warm and comfortable, but it can be a bit more complicated to install in cold climates or areas with high humidity levels. Contractors need to take extra care when storing their equipment, as the resin in aerosol foam is sensitive to cold temperatures and can thicken or even freeze. It's important to note that it's not necessarily more difficult to work with insulation in warmer climates than in colder climates. The R-value is the classification used to indicate the thermal resistance of an insulating material, or its ability to slow down heat transfer. Fortunately, there are closed-cell winter spray foam blends designed to operate within very defined temperature ranges.
This would give you a temperature difference of approximately 40 degrees between inside and outside, almost double that of homes in warmer climates. The components must be kept in a specific temperature range, as should the surfaces to be sprayed. When applied to a surface that is too cold, the final hardened foam can be rubbery and shrink away from the edges. It's also important to make sure that you have the humidity under control before adding insulation to your exterior walls.
