A sheet (1), preferably for use in the building sector, and in particular, for sealing the shell of a building, comprising a planar sheet body (2) that has at least one elastic layer as a sealing layer (17) made of a material of such elasticity and such restoring force that, when the sealing layer (17) is penetrated by a fastener (4), the material of the sealing layer (17) surrounding the fastening means (4) encloses the fastener (4) and provides sealing in the region of the fastener (4). Alternatively, the sheet body contains a sealing material which, upon perforation of the sheet body, is able to automatically emerge or swell to an extent sufficient to close or seal the perforation.
