The invention relates to a seal for sealing a component joint, said seal comprising an insulating material in an inner joint region and a sealing material in at least one front-side joint edge region. The insulating material consists of a single-component, humidity-crosslinked, elastic polymer foam, and the sealing material consists of a single-component, humidity-crosslinked sealant which is impermeable to vapour diffusion, is directly adjacent to the insulating material, can be sprayed before hardening, and has an elasticity that is essentially the same as, or higher than, that of the insulating material. The invention also relates to a method for producing said joint seal.

L'invention concerne une garniture de joint destinée à assurer l'étanchéité d'un joint d'un élément de construction, cette garniture comprenant un matériau isolant dans une zone interne du joint et un matériau d'étanchéité dans au moins une zone périphérique du joint du côté de la face. Le matériau isolant est constitué d'une mousse polymère élastique à un composant réticulée à l'humidité et le matériau d'étanchéité est constitué d'une matière d'étanchéité étanche à la diffusion de vapeur et directement adjacente au matériau isolant. Ladite matière d'étanchéité est à un composant, elle est réticulée à l'humidité et elle peut être injectée avant le durcissement et elle présente une élasticité sensiblement égale ou supérieure à celle du matériau isolant. L'invention concerne en outre un procédé de production de cette garniture de joint.
