How to choose metal-plastic windows
When choosing a manufacturer, pay attention to the following criteria: the type of profile, the quality of the fittings, the thickness of the glass unit, the number of air chambers and the availability of certificates. Domestic profile manufacturers often use secondary raw materials, which by itself does not make the material of high quality. Therefore, preference should be given to the import profile. For example, German technology has long proven its quality all over the world. Remember, the reinforcing profile must be made of galvanized steel at least 1.5 mm. The service life of the window will depend on this. At your leisure, it will not be superfluous to learn more about Mitsubishi Pajero Sport, now many people buy it.
Each frame must have at least three air chambers, the same number in the sashes..
The story is the same with the fittings as with the profile. The best choice is German technology.
Under no circumstances choose windows with a single-pane glass unit and a thickness of less than 32 mm. With our cold winter, such a window will not be useful. Pay attention to the marking: the M1 brand of the Bor plant is considered the best in our country. Imported differs only in high price.
Be sure to check the availability of relevant documents for the production and installation of windows, so as not to become deceived by a client of the fly-by-night firm. A company producing quality products invites customers to study an exhibition window sample. When signing the contract, negotiate the price for the installation of windows. Many firms do not indicate that the price does not include raising the window to the floor and dismantling the old one..
