These covering means therefore contribute to stopping the development and larval proliferation of insects at the underside of the body (1) of the panel (1) installed on site and forming part of a layer (14).
  • the sidewall (8) can be fixed to the upper face (2) of the body (1') by gluing/welding (by strip or by points) or stapling for example.
  • the strips of flexible porous material, forming means (5) for covering the openings on the surface of the joint zones (6) between adjacent panels (1) can optionally be fixed at the level of neighboring abutting panels which they cover in border (cf. figures 3 And 11 has 14 ), by gluing, welding or stapling.
  • the porous material constituting the sidewall (8) advantageously has the characteristics of the porous material described above in relation to the porous barrier layer (1") and the body (1') of the panel (1) those of the body (1') described below -above.
  • this porous material of the sidewall (8), permeable to liquids and constituting a barrier to the passage of insects of the mosquito-tiger type is a flexible material of the geotextile type, which advantageously has an average pore opening with a diameter of between 80 ⁇ m and 150 ⁇ m, of so as to prevent the passage of insects, in particular small flying insects, in particular substantially guaranteeing a ban on the passage of insects of the tiger mosquito type or the like, while being sufficiently permeable to the passage of water.
