Abstract (en)
[origin: EP3293337A1] A method for filling with thermally insulating material a cavity of a thermal break profile is described. The method provides for forming a thermally expandable profile comprising a thermally expandable composition. The composition is suitable for expanding under the pressure exerted by an expansion gas produced within the composition itself at a first temperature T E . The thermally expandable profile has a cross-section smaller than the cross-section of the cavity to be filled. The thermally expandable profile is inserted inside the cavity and subjected to a heat treatment at a second temperature T V greater than or equal to T E . In this way, the expansion gas is produced and exerts a pressure inducing the thermally expandable profile to expand and fill the cavity. Expansion under the action of the expansion gas allows completely filling the whole cavity, even if its cross-section shape is complex.
