To prevent rainwater from getting into the window bindings or joints of the window with the wall in the lower part, special sheets of metal are installed. These are the so -called castings. In former times, they were made from ordinary sheet iron, which eventually rusted and brown streams under the windows not only testified to metal corrosion, but spoiled the appearance of the facade of the building. Traditional painting with oil paints only slightly eliminated this undesirable effect, I had to paint iron products annually. Today, “external window sills” or ebbs are made from a wide variety of materials, they have a good aesthetic appearance, which often complements the design solution of the building facade, are durable, are not corroded and do not require annual painting. Firms engaged in the manufacture and installation of castings make them from aluminum, and polymeric materials. The standard length is 2 meters. They are made by order
Non -standard castings, the length of which can vary from 2.5 to 6 meters. The width is from 90 to 360mm. The dimensions depend on the profile of the window opening or the other surface on which the tide needs to be installed.
It is not recommended to install these designs independently, special skills and knowledge are needed here. With improper fitting and installing, rainwater will flow into the window opening and can manifest itself with wet spots and fluxes indoors. It is better to use the services of specialists who will make the necessary measurements, make castings and install. Modern aluminum, or from a galvanized iron, after manufacturing on a special potential machine, is plotted with additional processing, they are covered with polymer paint with polyester with the addition of the desired pigment, to the color of the facade of the building.
