Winter foam is a special type of assembly foam that can be used at low temperatures. Under normal circumstances, construction foam should not be used below 5°C because the humidity required for hardening is lower. Winter foam is therefore the solution for cold weather.
PU winter foam can usually be used up to temperatures of -10°C. Manufacturers also supply construction foam that can be used up to -20°C for countries with very cold winters. This does not refer to the temperature of the can; this should always lie above 5 ° Celsius.
