Abstract

L'invention concerne une bande de film destinée au domaine du bâtiment, dont une partie permet la diffusion et l'autre empêche la diffusion. Vu à partir d'un axe s'étendant dans le sens longitudinal de la bande, cette dernière présente, d'un côté de l'axe, une zone permettant la diffusion et, de l'autre côté de l'axe, une zone empêchant la diffusion. Le côté antérieur de la bande présente, dans une zone marginale de cette dernière, une couche pouvant être recouverte d'un enduit.
