The profiles are made from structurally semi-rigid materials with a contact surface / closing pressure ratio high enough to provide a water-tight seal and incorporating on their ends insertion and attachment points allowing coupling in metal profiles of the frame, in the shape of two basic semi-rigid profiles, a long profile (1) and a short profile (2), extruded from polyamide 6.6 with 25% glass fibre or a similar material or mixture of materials, in combination with elastic end profiles (3) or (4) of EPDM or a similar material that are inserted in the free ends of these profiles (1) and (2).
