Shutters

Shutters - a security shutters, collapsing in a roll. The main purpose of rolling shutters - protection of windows and doors of offices, banks, shops, apartments and houses. As a rule, shutters installed outside. Shutters shall consist of: - fabric that is made of slats, or put another way, profiles (horizontal bars, fastened together with hooks) - guides on which the canvas moves up and down - boxes, which the shutters "leave" folding on a roll - the shaft - bearings. Appearance, function and price of roller shutters depend on several factors: the material of which they are made, the size of the parts (in particular, the width of the lamellae), the mass of fabric and the method of control. Try to understand these four components. Material Shutters, more themselves slats that make up the fabric, made from aluminum or steel. Slats (profiles), aluminum and steel, come in different thickness and density, depending on the method of manufacture. Say, take two thin sheets of aluminum (steel) and between paving polyurethane foam, and then it all hold together a special device, resembling the press. By the way, polyurethane foam used as thermal and acoustic insulation. So that the shutters are made in this way shall retain 30 - 40% of the heat in the room. There is another method of manufacturing roller shutters. Profiles made by this technology, called extruded. Their production process like cooking meat. Profile of the desired shape "creeps" from a special machine - extruder, as the meat from the meat grinder. Lamella are obtained by thin, but more stringent than those made by the previous method. As I have demonstrated specialists "Radian", the panel can withstand more than 50 blows with a sledgehammer. The service life of extruded aluminum roller shutters - 4 - 5 years, and steel - 2 - 3 years. Shutters made of steel, is much harder and more expensive than aluminum. After all, for heavy construction, a more powerful electric motor, which, naturally, expensive. In addition, the steel shutters require a perfect installation - the slightest imbalance in the design of the installation will entail the load on the slats. Sizes and prices rolling shutters strength depends on the width of the slats. The wider the slat, the more durable fabric, and vice versa. Usually the width of aluminum profile 37 - 77 mm. The packaging of this feature is also reflected. It looks like this: for example, A37 (letter A stands for aluminum, number 37 - the width of the lamellae in mm), A40, A45, A55, A77. The price of aluminum profiles varies from 70 to $ 150 for 1/kv.m. depending on the width. Steel Profile denoted, respectively, C40 (C - steel, 40 - width in mm), S55, S77. Price - 100 to $ 160 per 1/kv.m. Ways to control shutters Protective shutters can be installed anywhere: indoors (in a window or doorway), outside (in the garage at the cottage, on windows). Location not fundamentally affect the choice of control method. Because it depends primarily on the mass of fabric. There are two ways to control roller shutter - a mechanical and automatic. Mechanical control of Band Management: The most simple and inexpensive (20 - $ 25), is designed for lightweight aluminum construction, weighing 15 kg. The principle of the belt controls the same as a seat belt in the car. A box with a ribbon installed indoors near a window. To close or open the shutters, the tape must be removed from the box and pull towards you (as in conventional braces). If you have shutters tape management, we recommend to install on the bottom slats mechanical lock (price 20 - $ 40). To lock the shutters, they should be dipped, to close the lock and remove the key. Cable (gear) Management: This method is suitable for heavier structures (weighing from 15 to 25 kg). Tape here replaces a more durable cable (for 35 - $ 45). Control mechanism, as is the case with a belt version, installed in the room. The difference is that the blinds rise-fall with the handle that is mounted in a box for cable. Rotate the gearbox (wide toothed cylinder, which is inserted and the wound wire), you make go roller shutters to and fro. Block design can be and with the help of a mechanical lock - it is set on the lower fins. Cardan Management: Designed for designs up to 35 kg (worth $ 60 -70). As in previous cases, the box in which the control system, located near the window inside the building. Shutters set in motion by rotating the knob. But unlike cable control, this mechanism is more complicated. By the gearbox joins Cardano (a long, thin metal rod). Kardan joins the handle at the bottom, and the gearbox, located at the top. He's the lead sheet in motion. Automatic control box is in models with automatic control box looks like a "mechanical" options. But the contents of this "box" other: inside is an electric motor, through which you can effortlessly open and close the shutters. To choose the right engine, again to take into account the weight of the canvas. For more heavy construction required a more powerful and therefore more expensive engine. The most popular electric German firm «Somfy», whose price - from 170 to $ 650. Average price for engine designs of up to 18 kg - $ 180, up to 74 kg - $ 260, up to 157 kg - $ 640. There are two types of automatic control design: push-button and remote. Push-button control is easier and cheaper (15 - $ 30). External buttons control switch recalls, and it is the same as the switch is attached to the wall. By clicking the button, you can omit or raise blinds. If you wish to equip key lock. In this case, simply touch the switch to design went up or down. If you choose the pushbutton in the "bezfiksatornom" performance, in order to lower or raise the blinds, it should hold up as long as the fabric will not rise or fall until the end. To stop it, simply remove your finger from the button. Remote control - the "cool" and convenient way to control shutters. But it is also the most expensive (350 - $ 400). You probably already guessed that the shutters are served with a command console that resembles the TV remote. Just press a button - and the shutters immediately begin to move. Remote control is reasonable to apply where there are multiple roller shutters: to raise the security shutters in several rooms on different floors. Of course, if you do not forget to connect them to the control center. Automatic control of the client's request can be completed alarm system with a combined electric motor. If you have an urgent need to continually open and close the shutters in the house, and electricity cut off very often, this system will be for you just magic wand. In this case, close or open the shutters can be manually, using Cardano, which is installed next to the box: just twist the handle and the shutters are set in motion. It is true that emergency management is 1,5 - 2 times more expensive than electric. To lock the system, you need to spend extra and put the automatic or mechanical lock at the bottom of the canvas. Automatic control of the sensor. First, just in case I will explain what the sensor. This device, the receiving, transforming and transmitting data by a special device of any measurements or, more simply, signals. In fact, it looks like this: on the roller shutter with automatic control of sensor pose and ask him to program. Depending on the program it will give signals and lower the blinds at certain times of day. For example, the lack of long house drew the attention of the robbers, for example, you are away from home for long. The sensor will create a "presence effect", raising and lowering protective shutters, suppose two times a day. In addition, it can "command" them down, if the window cooks up the sun or strong wind.
