Modern windows are easy to use, butsometimes there are unforeseen problems. Hence, the repair of metal-plastic windows with their own hands is an integral part of their use. You can, of course, call a specialist on the house, which can eliminate all the problems, but it will be expensive. Knowing the basic principles of operation of all components of this design, you can independently make repairs and adjustments. 
Metal-plastic windows are easy to care for and convenient to use - repair and adjustment of windows can be done by themselves.
Repair of plastic windows
Symptoms of the problems can be completely different. For example, on the window the handle can loosen, the window does not get into the correct position, condensation and drafts appear, etc. In order to correctly establish the cause, it is necessary to pay attention to some of the nuances:
-
The device of a metal-plastic window. the handle is out of order; - the window jammed;
- draft from the loop area;
- inflation from the sealant;
- the glass cracked.
On these and other breakdowns it is necessary to pay specialAttention. To replace the handle, you must first buy it. Try to choose the same as it was before. If any other mechanism is broken, you need to do the same. But before going to the store, determine the type of malfunction, because sometimes it is enough to simply adjust the mechanism. Of the tools you only need a screwdriver. Back to contents</a> If there is a draft Repair of plastic windowsis made and in the event that the draft is felt. This primarily indicates that some element of the mechanism is broken or loosened up. Initially, you need to determine the area from where the wind is blowing. In the cold season it is much easier to do this, since it is enough to hold a hand over all the connecting lines of the leaf and frame and in the area where the frame with the window sill is joined. In a warm period, it is necessary to bring to the same places a lit match or lighter. The second is preferable, since the burning time is longer. Accordingly, in the area where the flame tab is deflected, and there is a problem. 
Scheme of sealing the plastic windows. If blown between the sill and the frame, you just need to seal these places. The initial installation of metal-plastic windows implies the application of a sealant, but not all masters are responsible for their work, so check all these areas yourself and, if necessary, make another seal. Only it is necessary to do this after all old influxes have been cut off, that is, excess frozen foam. Sometimes a draft occurs in the area of the sash of the window, which indicates that the sash is not quite snug against the frame or it has warped. Basically skew occurs where the handle is located, but in the upper corner. Perhaps the reason lies in the subsidence. To make the installation, you need to raise the corner part of the sash or completely replace the double-glazed windows. That is, it must be removed from the frame, while lifting (easily) the problem area and fix it. After that, the double glazing unit is reinstalled. If the inflation is due to the fact that the frame is not tightly pressed, then it is necessary to correct the clamping device, that is, pressing the trunnion or the stop bar is performed. It also happens that during the installation of the master forget about the installation of some fittings, so in these places begins skvozit. Check and install the missing items. The majority of manufacturers include special clamping devices, which are mounted on the side of fastening the loops from above and below. Back to contents</a> Installation and adjustment of the handle 
In order to replace the broken window handle,it is enough to use a conventional screwdriver. If the handle of the metal-plastic windows has broken, it must be replaced, but for this it is not necessary to remove the entire mechanism. In order to remove the broken element, it is necessary to unfold the plate (plastic) by 90 ° and turn off the bolts under it with a screwdriver. All the broken is removed, and this place is being installed a new handle in the same order in which it was disassembled. That is, the handle must be attached to the mechanism and tightened with the same bolts, then return the plate to its original position. If the window, being in the clear view, can not be closed then, then the pen is jammed. And in this case you can solve the problem yourself. The fact is that modern models of metal-plastic windows are equipped with certain blockers that work if the handle is jerked by a sharp movement. In the handle area is a metal plate, which has a spring. It is her that should be pressed to the seal and just turn the handle itself. The window leaf should be located only in an upright position. If the work was not successful, then the blocker needs repair. If you try to forcefully close the sash, there is a risk of breaking the gearbox for locking. To repair the bollard, you must first remove the window leaf and decorating cover, then remove the pin. The removed window is installed on the floor in a vertical position, the screws and scissors are unscrewed. Then the locking device is completely removed, and the scissors are installed in place. If you want the lock to be after all, then you need to buy it and make the installation. The handle can lose the property of turning. This indicates that the leaf has fallen or the lubricant has simply run out. After the lubrication of all moving parts, the handle must again work. If this does not happen, then just loosen the screws on the hinges. If this device to open the window simply loosened, then tighten the bolts. If the handle becomes problematic to hold to the full state of closure, then you overdid when tightening the fasteners: just loosen them a little. Sometimes all mechanisms of this kind must be cleaned, because there is a lot of dust gathering, which eventually interferes with the normal functioning of the device. To do this, it is necessary to dismantle all the mechanisms in turn and clean it with a brush, or even better to vacuum the entire system with a vacuum cleaner. Then everything is smeared and assembly of spare parts is carried out. Back to contents</a> The problems of the clamping mechanism The reason for blowingcan serve as a rubber band, which eventually weakens and loses its volume. If so, replace the seal. Windows are sensitive enough to heat changes, which can be the cause of the malfunction. In fact, the fittings are provided with appropriate regulation, but very few people know about it. Quite a frequent problem is the failure of the clamping device, which includes adjusting for the season so that the structure does not suffer due to a temperature drop. As a rule, the position of the clamping mechanism should be changed twice a year, that is, in the autumn and in the spring. For this, no repairs are needed, but only adjustment. On the end part of the sash there are cylinders that protrude. They have an oval shape and are located in the holes of the plugs. In other words, they are trunnions or eccentrics. On the frame there are reciprocal engaging parts, into which the trunnions enter during the turn of the handle. Due to this, the leaf closes tightly. To change the position of the pressure, you need to scroll trunnions or reciprocal hooks - as convenient. 
Adjustment of clamping pins of metal-plasticwindow. This is done in the following way: the most protruding part of the trunnion rotates into the inner side of the surface of the whole structure, thus the clamp becomes stronger. In order to weaken it, these turns must be made to the outside. Accordingly, the weakening is done in the spring, and the pressure is applied in the fall. After that it is necessary to adjust the canopies. In this case, it is better to consider a variant of a window of a fan-like type, since it is the most popular and complex one. The fanlight system allows the wing not only to open, but also to be kept in a state of ventilation. To do this, the cap of the clypeus is removed from the lower part, but do it carefully so that it does not burst. Then you will see a hexagon bolt. There is, of course, one more, more hidden, but you will not need it. With the hexagon, you can easily adjust the clamping state. Upon completion of work, all components must be assembled. In the upper part of the window sash there is a device called scissors. To make repairs in this area, you need to put the window into the open mode. Only in this way will you get the adjusting bolts in the scissors. On the butt near the handle there is a clip (lever), on which it is necessary to press. Remaining in this position, the handle turns into a ventilation mode. An open window will take a convenient position for you, keeping your weight on scissors and a shed. So you get to the head, which helps to make adjustment. After this, all the details and positions are reversed. Back to contents</a> Other malfunctions and repairsit happens that the leaf slightly begins to touch the window frame. If this occurs on the side where the handle is located, then the flap is lifted and its upper part is rotated towards the attachment from above. If it touches in the middle area along the butt, then the leaf is shifted to the canopies. When you move the touch point to the top or bottom side, you need to deploy the leaf to where the offset occurs. At the top grazing at the end, a turn is made to the lower canopy and vice versa. To completely replace the seal, you first need to pull out the old one and be sure to thoroughly rinse and wipe all the grooves. After this, it is necessary to grease them with special glue and to install the sealant. It is necessary to start it slowly and very carefully, because this will determine the quality of the clamp. The sealing cord must never be squeezed or stretched. After its installation it is maintained for a while (depending on the glue), and only then you can close the window and assume that the repair is finished. If the problem is broken glass, do not despair. But if you think that you can not cope with this kind of problem, then call the master. Although try to do this repair yourself is worth it. You do not lose anything and at any stage you can ask for help from specialists. Now you know how to fix the defects of metal-plastic windows with your own hands, at least, the most common. Recommendations of experienced professionals will always help you in the implementation of your plans.
