Abstract

A method and apparatus for the formation of an intumescent seal 240 is disclosed. A receiving substrate is extruded (fig.2A) intumescent material is placed in the substrate (fig.2B) which substrate is then closed around the intumescent material (fig.2C). A sealing structure 230 is then extruded to surround the containment structure. Also disclosed is a corresponding seal as formed by the method and apparatus. Such an approach reduces the susceptibility to damage since the sealing structure is not susceptible to delamination and any edges of the containment structure are no longer accessible. Also, forming a sealing structure provides for more reliable external dimensions. The seal may find application as a heat swellable, fire retardant, door or window seal, or similar.
