In one aspect, the disclosure provides an expanding foam insulation material, the expanding foam insulation material being dispensable and expandable to provide an expanding foam insulation material having a maximum foam height; and no local pressure maximum of more than 500 Pa, wherein for each local pressure maximum in excess of 50 Pa, a time difference between a time of the local pressure maximum and a time of 95% maximum foam height is no more than 80 seconds. The expanding foam insulation material is desirably provided with Class A fire rating.
