A properly functioning plastic window is necessary to seal the room. With normal adjustment, the fittings press the sashes against the frame, and they are controlled by the handle. But it happens that the window does not close. It is important to determine the cause of this phenomenon, and then fix the problem. Read more about this in the article.
Sash tilt
Due to skew, a gap may appear between the sash and the frame, into which air from the street will enter. This defect does not allow the sash to fall into place. It will cling to the side and bottom ledge of the frame.
If the plastic window does not close, you need to change the angle of the sash, move it in a vertical or horizontal plane. To do this, there are adjusting screws located on the hinges of the sash. From them it is necessary to remove the protective pads, under which there will be holes for a hexagon or an asterisk key. While turning the screws,obtain normal closure of the sash and elimination of the gap. The lower loop is adjusted in 2 planes, and the upper loop can be without adjustment or shifted to the right and left.
Loose fit to frame
The window does not close when the seal loses elasticity, and also due to a failure to adjust the pressure eccentrics:
- Seals must be periodically washed and treated with silicone grease. If this is not done, they lose their elasticity after 5-6 years. Then they crack and let air into the room. If this happens, then you should buy and replace the seals. To do this, remove the old products, clean the grooves, and then install a new gasket.
- The eccentrics, which are located at the ends of the open doors, can be fixed in 2 positions: “Summer” and “Winter”. In the first case, the clamp is not very tight, and this may not be very convenient in winter. To set the eccentrics to the desired position, you need to turn them by 90 ° using pliers, an asterisk or a hexagon (the choice of tool depends on the type of fittings). This allows you to get a tight clamp. When the cold is over, you need to put the eccentrics in their original position.
Window failure in tilt position
If the window handle does not close after airing, a possible reason is the exit from the grooves of the fittings, which are called "scissors". This element is used to open the sash in ventilation mode. The handle will be locked. With simultaneous reclining and plowingwindows, there is a risk of breaking out the lower hinge, since the weight only affects it. You should not throw the sash in this form, it must be covered. If the handle does not turn well, do not apply too much force, otherwise it may cause more damage.
How to fix this defect if the window does not close? Work is performed according to the following instructions:
- The sash must be removed from the frame. To do this, remove the trim from the upper hinge, pull the hinge pin down with a knife or screwdriver. Then it is pulled out by hand or with pliers.
- Then you need to remove the sash from the bottom hinge. To do this, you should lift it up a little.
- The sash must be placed on the floor with the bottom.
- It is necessary to find the grooves into which the "scissors" can enter, and install them. To do this, press on the end of the sash on the handle rotation lock.
- Then it is important to check how the pen works. It should turn easily.
- The sash should be replaced.
In some cases, the flying "scissors" are installed without removing the sash, if there is room at the top. If the handle does not turn and the plastic window does not close, you must troubleshoot carefully so as not to aggravate the situation.
Simultaneous opening of the sash for plowing and ventilation
The window does not close often because the handle is set to the “Open” position, and it is moved up during the ventilation mode. It turns out that the sash will recline and swing open. The handle is locked. Is notmeans that the window is broken. It's just that the sash is in a position where it can't be closed.
The problem is fixed as follows:
- The handle is in a vertical position. It is necessary to press the sash to the frame in the upper corner. It will be installed in its place.
- Then press the lock on the sash.
- Shift handle to open position.
- At the end, the sash must be closed.
Fault in Closed Mode
If the window handle does not close completely in closed or open form, then this may be due to an untimely actuated sash lock. It is necessary to press it with your hand, and then put the handle in the usual position. This will allow you to close the window normally.
It also happens when the blocker misses the stop with which it should engage. This is due to the thermal expansion of materials. You should unscrew the stop from the frame, and then put a gasket under it. Then everything is screwed into place. If there is a movement of the sash, it is necessary to move the stop in the vertical position.
The pen does not work
If the handle does not turn, the window does not close, then the reason for this is usually the drying of the lubricant on the fittings. If the design works for several years, then this problem will be natural. In this case, it is necessary to lubricate the fittings using special holes located on the top and sides of the sash.
Any lubricating fluid or oil is suitable. But it is advisable to use a silicone agent. After that, it is necessary to twist the handle so that the lubricant is evenly distributed. Usually helps if that was the reason.
Repair can complicate the situation, during which the doors become clogged with dust and debris. In this case, lubrication will not be the solution. It is necessary to completely disassemble and wash the fittings. For this, it is better to call the masters. It is important to check if the handle functions with the sash open. If in this case the plastic window does not close well, then the reason is related to the breakdown of the fittings. You will need to call a specialist. If the window is functioning, then it is necessary to check whether the eccentric of the sash end rests against the clamping part on the frame. Usually this serves as a hindrance to closing. It is necessary to move the platform or sash up or down.
Handle broken
If the window does not close completely, then the breakage of the handle may also be the cause. Or it could just be loose. You need to tighten the handlebars. To do this, the decorative cap located at the base is rotated 90 degrees. There are 2 screws that need to be tightened with a screwdriver. Then the plug is installed in its place.
If the handle breaks, unscrew the retaining screws, and then remove the old handle from its place. Installing a new part is easy. It must be placed in the hole, and then tightened with screws. You will have to change the fittings if you wantinstall handle with lock.
Prevention
To avoid any problems with the window, you need to follow simple recommendations:
- Quality installation of double-glazed windows is important. This means that both corners must be at the same level. If there is a warp, then due to the large pressure, the frame will bend, causing breakage and looping.
- During installation, the product should not be subjected to mechanical damage.
- Install the window preferably on mineral glass wool.
- It must be remembered that the width of the window sill should be such that it does not block the passage of heat from the battery.
Proper use
You also need to follow the rules for using windows. A few simple tips will help with this:
- Do not apply too much force when closing as this may damage the handle.
- It is forbidden to hang any weights on the handle.
- During opening, do not press hard on the slopes.
- When there is a strong wind outside, the window should be closed.
- Make no damage.
- There should be no extra items between the frame and the sash.
- The leaf must not be open.
- Humidity control is important - no more than 50%.
- Every day the sash must be opened for ventilation.
Care
Equally important is the care of plastic windows. It is as follows:
- In double-glazed windows there arechannels to remove excess moisture. They are located at the bottom of the frame. It is important to monitor the status of these channels. They should be cleaned regularly to remove dust and dirt.
- Cleaning of fittings should be done only with special tools that will not be harmful to anti-corrosion coatings. Do not choose alcohol solutions, dish liquids, nail polish removers or gasoline.
- Increase the shelf life of the product will allow the lubrication of fittings (2 times a year). In addition to silicone oil, you can use machine oil.
- It is important to control the quality of fixing the fittings to the frame, as this determines the smooth functioning of the window and its serviceability. To do this, it is necessary to check the strength of the screws in the plastic. If they are weak, they are pulled up.
Thus, the plastic window may not close for various reasons. Many problems can be fixed on your own. If it is difficult to deal with this problem, then you need to call a specialist.
