DIY plastic window repair shows through

Often, after installing a plastic window, it starts to blow from it. Such a nuisance can appear not only with a new window, but also with a structure that has already been mounted for a long time and has been used for a single year. There are many reasons for this trouble, and each case needs its own solution to the problem. Often, you can eliminate the blowing with your own hands, but sometimes a call from professionals is necessary.

Can blow from any part of the window:

1. At the top of the sash.
2. Below the sash.
3. Under the seal.
4. From the slopes.
5. Under the windowsill.

Window manufacturers promise minimal heat loss, reliability and complete tightness, but there are many reasons for this problem. First of all, it is necessary to find out for what reason flows of cold air appear near the window.

Perhaps it is the air convention due to the large temperature difference? A simple candle will help to find out - it is lit and held along the borders of the sash - the deflection of the flame will show where the window is showing through.

Carefully examine the joints of the slopes and the window frame - if their installation is done incorrectly or poor insulation is done, then possibly cooled air comes from the slots (both on the slopes and from under the windowsill).

There are 3 types of reasons for blowing out windows:

1. Installation errors.
2. The window structure is assembled from fittings or low quality plastic.
3. Defect in the assembly of the window structure.

More broadly, the reason for blowing can be found:

1. If the fittings are poorly adjusted, the sash will not fit well.
2. Due to installation errors, the geometry of the window structure is broken.
3. Used fittings of low quality (it is not advisable to save money here).
4. Dirty or poor quality seal.
5. Violation of the integrity of the frame - plastic bought on the cheap can become brittle from low temperatures or not withstand heating in the summer.
6. Poor thermal insulation of slopes, their installation with errors.
7. The installation of the window sill was done incorrectly and, as a result, gaps formed under it.

Why are the blowing of the window structure formed:

1. Trunnions installed along the perimeter of the sash, it is necessary to move to the extreme position (they must be moved clockwise) - the adjustment is performed using pliers or a screwdriver. Attention: the setting is made with the window open. It is imperative to move all existing pins, otherwise the structure will be damaged.
2. Some window manufacturers use an automatic method in their products. transferring the window to the required mode - the set of accessories includes a special roller with a ring. It moves and changes the modes of operation of the window structure.
3. If you have no desire to solve such problems after installing windows, then it is necessary to take protective measures when choosing a window and its installation. This is a choice of high quality window construction, reliable fittings and a reliable and strong profile. Of course, you only need to buy a product from trusted companies.
4. In addition, you need to make sure the quality of the installation of the window, remember that professionals always provide a guarantee and the necessary service during operation, during which you can eliminate possible defects without your own costs.
5. It is important to comply with the requirements of the rules for operating the structure, keep the condition of the seal under supervision, lubricate the fittings in a timely manner. In addition, you can insulate the space under the windowsill until a problem arises with it.To do this, the seams between the plastic structure and the wall are carefully coated with sealant. Additionally, protect the polyurethane foam from the negative effects of moisture.

If the window structure has been used for a long time, but drafts have appeared only now, then it is possible:

1. Sash sagging. After a while, window sashes under their own weight may sag, as a result, they will not fit snugly against the frame. Only adjusting the fittings of the structure can help here.
2. Rubber seals. These elements need to be looked after for the entire service life - they need to be renewed with silicone-based lubricant at least 2 times a year, otherwise they will dry out. But proper maintenance does not guarantee the safety of the seal after a while, especially if a cheap and low-quality seal was installed during its manufacture. If the fault of the appearance of blowing lies with the seal, then this defect can only be eliminated by replacing the sealing gum.
3. Assembly seam. The installation of the window structure could be made with flaws and the foam in this case will come out from the outside of the wall, collapsing from sunlight and moisture. The seam, without high-quality protection from external influences, collapses in a short time, the foam, turning into sand, pours out of the seam, as a result, voids appear. As a result, drafts appear and even freezing of the slopes, the window itself and the window sill is possible.

There are other reasons for the formation of drafts, for example, poor functioning of the strike plates, which serve to tightly press the window sash, but in this case, look for the cause of the defect and decide how only an experienced specialist should.

Often, convection (air circulation) is considered a draft. In winter, a stream of cooled air descends over the glass surface, creating a blowing sensation.

Today in cities, and in many localities, most people live with plastic windows. This is due, first of all, to their excellent characteristics and advantages, which made it possible to abandon old wooden windows. At the same time, despite their very tangible advantages, plastic windows have some unpleasant moments that are associated with their operation.

This is explained by the very design of the plastic window, its characteristics, as well as the conditions in which it is located. Most of the problems that arise during the operation of a plastic window can be solved by ordinary adjustment, and with your own hands.

1. The installation of plastic windows is most often carried out and regulated in an already finished window, but after a period of time, window structures are capable of deforming under the influence of external factors. This is especially true for new homes, as they shrink. As a result, the dimensions of the sashes change, the gasket and fittings become dirty.

Cracks appear, the handle becomes difficult to move, the sash sticks or does not open at all. As a result, drafts appear, heat and sound insulation is disrupted.
The next reason may be poor-quality window installation, as a result of which drafts may appear, which is especially unpleasant in winter. Defects in production are also possible. But it will not be possible to correct the situation with your own hands in all cases - you may need to re-install it.

In most cases, the usual adjustment will be able to help here, as well as replacing the sealing rubber and gluing some of the gaps with silicone.

Adjustment is required in cases:

• The sash touches the box or hardware parts during opening (closing).
• There is a noticeable draft coming from the window.
• The handle has acquired a tight movement or is completely loose.
• The handle gets stuck and the window does not close as a result, and so on.

To work, you need to arm yourself with the following tool:

• A set of hex keys (4, 6 mm).
• Pliers.
• A set of star attachments.
• Screwdrivers (Phillips and flatheads).

You may also need the following tools if the sash does not open well or does not open at all:

• A spatula for double-glazed windows.
• With a rubber hammer.
• Spatula.
• Lining for double-glazed windows.
• With a soft brush.
• Fittings lubricant.

Sashes on almost all modern plastic windows are adjustable in three planes, which makes it possible to achieve the correct positioning of the sashes both in the frame and along the sash perimeter, achieving a better state of pressing the seals.

Here it is necessary to take the sash up, towards the upper hinge. The up and down sash adjustment is carried out as follows.

• The flap opens.
• Use a hexagon to turn the adjusting screw, it is located at the end of the sash near the upper hinge. Clockwise, it is twisted a few turns.

Here it is necessary to take the sash towards the hinges:

If the side of the sash only touches the bottom of the frame, then the sash should be taken towards the lower hinge. This is done using the adjusting screw - it is located under the lower hinge.

On the side of the handle on the side end of the sash, you need to find a system of eccentrics - it allows you to adjust the tightness of the sash to the frame.

Of course, depending on the manufacturer's company, the appearance is different, but the windows work according to the same principle.
