This braided wooden windshield is made of a wooden frame that holds a set of plywood blades that are interwoven thanks to the flexibility that allows them their thinness (plywood 3-ply 3mm thick, external quality CTB-X, class 2 or 3 bonding). Placed in a balcony, it is also a good screen that can be dressed in a climbing plant in the manner of a trellis.

1. On a sufficiently large workbench, or on a table or on the floor, lay plywood boards, 3 to 4 cm wide, side by side. These horizontal blades must be sufficiently long (about 2 m) for the windscreen to be effective. In a wooden block of 30 x 30 mm section, cut a series of wedges 7 cm long. Place them between the blades so that they are equidistant and parallel (check the parallelism with a meter). The size of the wooden wedges corresponds to the days of the braided windbreak. Determine the position of the first transverse blade by measuring 9 cm at the end of each horizontal blade (7 cm for the day and 2 cm for embedding in the frame). Braid the first transverse blade by placing it carefully. Plates are typically 2.50 m long and 1.22 m or 1.55 m wide. And the plating wire is generally in the direction of the first dimension given by the manufacturer.
2. Place a cleat at the edge of the table, on the first transverse blade with two clamps, secure this first assembly. Put the eight wooden blocks against the transverse blade: you determine the position of the second. The use of wooden blocks makes it possible to obtain equal joints and regular braiding. Then weave the second transverse blade. Do not try to pass it near the holds, as this will cause you to bend the horizontal blades excessively. Pass it rather near the free end of the blades then bring it into position with a wooden mallet.
3. Place a new set of wood wedges between the horizontal blades, resting against the cross blade. Set up, in the same way as before, the second transverse blade. Check that the wooden wedges are correctly placed: there must be no gaps, since the defects are difficult to catch. To braid the fourth transverse blade, remove the first row of wedges and place it against the last laid blade.
4. When braiding is complete, place a long wooden ruler (or cleat) over the end of the cross blades. Trace the saw lines so that one day (equal to one shim width) is created. Allow an extra 3 cm for adjustment in the frame. Saw the cross blades with a fine-toothed handsaw.
5. The elements of the frame must be sufficiently wide (5 cm) to allow grooving. Use a circular saw. Make a groove 3 cm deep and equal in width to the plywood blades.
6. The framing slats are fixed in pairs by a half-timber square assembly, sufficient in this type of installation since the recessed blades reinforce the strength of the assembly. Hatch the parts to be removed, so as not to make mistakes; saw with a handsaw
7. The horizontal blades should be sawn so that the last days are equal to the others. Always allow 3 cm for embedding. Glue the parts of the frame to be assembled using an exterior type wood glue. Position the four sides by embedding the end of all the blades into the groove. Use a wooden mallet to make a proper embedding.
8. The assembly is reinforced by screwing. The windshield is intended to be placed outside, use screws chrome, stainless. Two are enough for each assembly: do not screw too close to the edge of the cleat, so as not to burst the wood. Drill pilot holes using a spin. Mill them so you can then hide the screw head with wood pulp.
9. The finishing can be done in different ways. Remember that the windshield, located outside, must withstand the weather. Treat the wood, before finishing, with a protection product against moisture and mold. If you choose to paint the windshield, use a paint intended for the outdoors. A "marine" varnish (phenol or polyurethane), used for boats, beautifies the wood by protecting it. Spend at least two coats with a brush.
10. The windshield must be securely fastened. Use plastic or metal (chrome) brackets. Put it in place: using the plastic square, find the place of the holes to make in the wall. Use an electric drill with a concrete drill. If necessary, equip it with a depth guide to make holes to the desired size.
11. Push dowels into the holes using a hammer to securely tighten the square to the wall. Always use chrome screws. Then find the location of the holes to make on the frame, before fixing the square to the windbreak itself.
12. In the installation shown, the windshield is fixed against a metal railing. The simplest is to screw it directly into the sheet, using special screws, self-tapping. Begin screwing into the frame and locate where the screw should penetrate the metal. First, punch the steel plate with a hammer: put the windshield back in place and finish tightening the self-tapping screw. The structure of this windshield allows to use it as a trellis. A soil tank, placed on the ground, at its foot, can indeed accommodate a climbing plant (consult a gardening guide for planting times). You can then choose to paint the wood; the white marries very well with the green of the foliage and enhances the color of the flowers. In any case, apply a treatment product to prevent any risk of mold but let a few weeks pass before hanging a plant, the time for these products to completely dissipate their solvents, if they are provided.
