Guide - Graphite Styrofoamprint

Styrofoam graphite is produced in Poland only a few years. The production process is the same as the white Styrofoam, as producers benefit from the final intermediate in the form of graphite granules, which is sufficient lather, shape and cut. Its insulating properties are certainly better than the "white brother" because the graphite color, they also reflect the effect of thermal radiation. In practice, polystyrene, graphite is about 25% warmer than white. If the price is much higher than the 25% more, there is no economic justification for its use. However, if the difference is less that the economic effect is visible. It must be remembered that using polystyrene by 25% "warmer" we can apply a layer with a thickness less, saving a bit on the waste, the length of dowel, and we have shallow embrasure (węgarki), which may be crucial for large thicknesses. Using graphite polystyrene 15 cm thick obtain roughly the same insulating effect as at 20 cm of white styrofoam. Zstosowanie polystyrene graphite, however, involves certain difficulties, and he should be special treatment. Czrny color results in a rapid and strong heating of both the sun and diffuse radiation. Styrofoam is an excellent insulator so the temperature difference layer exposed to the sun and the opposite layer (the one from the wall) after sticking, it may even reach tens of degrees! This implies that the styrofoam plate bends like a banana. The stresses can be so large that after a few hours from sticking to the wall panels themselves Styrofoam begin to fall away. Do not be terrified. The contractor shall be for the security wall in such a way that the sun did not fall directly on the freshly finished in the wall. If possible, work should be carried out on sheltered scaffolding nets, tarpaulins, in the days without sunlight, at temperatures up to 25 ° C. A good way to avoid complications in the summer is to work in the late afternoon on the walls Eastern and early morning on the walls of the West. Styrofoam graphite is reduced adhesion to most adhesives so it's worth gently abrade the surface with sandpaper, a special float abrasive (rasps) or a wire brush. These are the official recommendations of manufacturers of such polystyrene. Personally, I recommend adding a method to "pancake" three mortar polyurethane adhesive patches (eg titanium EOS), which dries in 1 hour and still holds the record before the traditional polystyrene foam adhesive binds so that the stresses in the plate are unable to tear her away from the wallGood luck.
