Abstract
A multi-layered sealing sheet for the building industry is prepared so that all plies which contain elastomeric synthetic resins are devoid of vulcanization accelerator and consist of an elastomeric synthetic resin on the basis of ethylene-propylene-diene terpolymers and/or ethylene-propylene copolymers. A reinforcing insert is laminated in between the layers with the use of heat and is a fabric, a mat, a knitted material, or a similar material of synthetic resin fibers and/or glass fibers.
