• the second portion (32) of the sheet (3) is made in such a way to be used in cold seasons, that is to say of a windproof and waterproof material.
• the second portion (32) is preferably made of transparent material so that the few rays of sunlight present in winter months can still pass through it and possibly heat the space behind the second portion (32) of the sheet (3).
• the second portion (32) may be made of a transparent and/or colored PVC sheet or the like.
• the first portion (31) and the second portion (32) are joined to each other at an intermediate joint section (33).
• the intermediate joint section (33) may consist of a section in which the first portion (31) and the second portion (32) are welded or co-molded together in such a way that the sheet (3) is a single, non-separable sheet.
• said intermediate joint section (33) may comprise coupling/uncoupling means that are arranged between the ending edges of the two adjacent portions (31, 32) and are configured to allow a quick coupling and uncoupling of the two portions (31, 32).
