Zusammenfassung:	The present disclosure relates generally to methods, devices and systems for insulation, e.g., of cavities associated with walls, ceilings, floors and other building structures, with foam insulation. 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. La présente invention concerne de manière générale des procédés, des dispositifs et des systèmes d'isolation, par exemple, de cavités associées à des murs, des plafonds, des sols et à d'autres structures de bâtiment, par une isolation en mousse. Selon un aspect, l'invention concerne un matériau isolant en mousse expansible, le matériau isolant en mousse expansible pouvant être distribué et étant expansible pour obtenir un matériau isolant en mousse expansible présentant une hauteur maximale de mousse ; et sans maximum de pression locale de plus de 500 Pa, où, pour chaque maximum de pression locale dépassant 50 Pa, une différence de temps entre un temps du maximum de pression locale et un temps de hauteur de mousse maximale de 95 % ne dépasse pas 80 secondes. Le matériau isolant en mousse expansible est de préférence pourvu d'un indice d'incendie de classe A.
