<p>A sealing tape (8) for sealing an open end (42) of a multiwall sheet structure includes a layer (48) of thermoplastics material, such as polyamide or vinyl, having a profiled surface comprising projections (52) and valleys, channels or troughs. The profiled surface is locatable over the open end (42) of the structure and is heat softened so that the ends of components of the structure can embed into the thermoplastics material and be supported thereby when solidified. The profiled surface may include a plurality of projections, which projections may be of a generally domed shape or may be elongate and extend longitudinally. Methods of forming the sealing tape and sealing an open end of a multiwall sheet structure using the tape are also described.</p> |
