The aluminum profile is considered one of the best materials used to manufacture the frame window. Aluminum frame strong, durable and fireproof, and they are thinner and lighter. This profile does not crack and does not oxidized, is covered by coating. A wide range of colors shades during deposition allows for the most daring colors. Aluminum - lightweight, durable, easily cleanable construction material, long-life; clean, free of impurities of heavy metals, does not release harmful substances when exposed to ultraviolet rays and remains serviceable in all weather conditions with temperature changes from -80 0C to +100 0C. In contact with oxygen, its surface is oxidized, creating a protective layer. Aluminum, in contrast to other materials, it keeps its structural properties with temperature changes. After surface treatment aluminum products, they become resistant to the harmful effects caused by rain, snow, and smog.
One disadvantage of aluminum is that its direct contact with other metals can cause the flow of electrolytic reactions, which leads in turn to strong electrocorrosion aluminum, up to his destruction. Aluminium profiles are usually made of three-component alloy of aluminum, magnesium, silicon. Aluminum has high thermal conductivity, so usually all manufacturers produce two types of profiles: 'cold' and 'warm'. Cold profiles for windows (with high thermal conductivity, without thermometer insert) are not suitable for heated buildings facades. They are used for interior vestibules for the device, the second line of doors.
Warm profiles are in their construction with insulating insert, which is interrupting the flow of heat, provides better insulation profile. Box is made of fiberglass-reinforced polyamide. To improve the thermal and sound insulation, it can be filled with polyurethane. Thermal conductivity coefficient k characterizes the amount of heat in watts (W), which passes through 1 m2 of construction at a temperature difference on both sides of one degree Kelvin, a unit of measurement Vt/m2K. The lower the value of k, the less heat transfer through the structure, ie above its insulating properties. Unfortunately, the simple conversion of k in Ro is not quite correct because of the difference between the measurement techniques in Russia and other countries. According to DIN 4108 All materials are divided into the following groups: 2.2, 2.1, 2.0 and 1.0. Originally all sections of Germany and the Russian market their overwhelming majority, the group delivered 2.1. In accordance with the first stage of SNIP II-3-79 * a level of insulation is enough. It was the cheapest profiles with simple O bands, which do not create additional air chambers. The coefficient of heat resistance according to DIN was 2.8 W/m2K, which corresponded to the Russian Ro at about 0.35 W/m2K. To date, entered into force on the second phase of the program on teplosberezheniya (by SNIP II-3-79 *), and the materials group 1.0 to DIN (Ro at about 0.55 W/m2K) are preferable. A similar coefficient of heat transfer is achieved and the presence of large thermal break extra petals in the seals, which create an air chamber. Support profiles performed with drainage channels, channels for the rubber seals that hold the glass and glazing, and a screw channel for allow for screw mounting at any point in a basic profile of the pressure plate. The camera can be inserted into the profile of an additional aluminum reinforcing rib. The size of the carrier depth profile can be vary depending on the recommended or necessary rigidity. Profiles can anodize aluminum in natural color, to simulate the surface of the wood, paint powder in any color RAL. Form of external trim strips can be very different - and box-flat, semi-circular and lenticular.
