How to insulate plastic windows - the causes of drafts and how to independently increase the thermal insulation with video

Now many people change wooden windows to plastic ones. However, during operation, their tightness may be impaired. People are faced with the question of how to insulate plastic windows so that the violation of integrity is corrected, and the air from the street less penetrated into the room. It is important to understand the cause of the problem and solve it, and then make the isolation.

Why blowing from plastic windows

Before you start to correct the current situation, you should find out why blowing occurs, whether there is fogging. There are many reasons, but there are several basic ones:

1. Marriage in production.
2. For manufacturing windows, poor quality plastic was used.
3. Bad accessories were installed.
4. Errors were made during installation.
5. Poor quality sealant material.
6. Slopes were not properly insulated.

How to determine the cause of

To begin with, make sure that the window is exactly blowing. To understand this, you can bring a lighted candle or lighter to the joint of the sash and frame. If the flame fluctuates, then it blows from the window. Then the candle should be held around the perimeter. The problem often occurs at the junction of the window frame and the slope. This indicates poor installation, so you need to contact the company and ask for a correction( if the warranty period has not expired).

The cause can be covered in the wrong adjustment of the fittings or in the absence of installation for winter operation. To do this, try to open the window and look at the lock. Independently identify the problem and configure not everyone can, therefore it is better to call the wizard. Sometimes the cause is the violation of the geometry of the window. In this case, there is a bad pressure of the leaflets, because of this contiguity, there are drafts. It will be necessary to completely re-install the double-glazed windows.

Another way to diagnose is to check the condition of the seal. Probably, it serves as the reason of inflation or leakage of moisture( condensate is formed), if it is of poor quality or highly contaminated( remove all dust).Under the influence of low temperature, it loses its elasticity. You should touch it with your hands, checking for elasticity. If the reason for the deterioration of the insulation, then its replacement is necessary.

The next step is to pay attention to the quality of plastic. Unfortunately, an average person can not visually distinguish high-quality plastic from bad, for this one needs a specialist. However, if all of the above methods of diagnosis did not reveal the reason, then most likely you bought windows from bad material. We will have to dismantle and put a new metal-plastic construction.

When it's better to make insulation

The problem of window inflation occurs in the cold season. In the summer, people either do not notice this, and with the onset of cold weather the air from the street becomes palpable. It is best to make thermal insulation in spring or summer in calm weather .Sealing compound requires a special temperature, they can not be used in winter weather. There is plus insulation in the cold season: it is clear what place to insulate and whether the chosen method is effective.

Than to warm plastic windows

It is extremely important to understand how to insulate plastic windows. There are many methods of thermal insulation, therefore each person can choose for himself comfortable. The insulation for plastic windows is as follows:

1. Mounting foam is a quick and affordable method. However, the foam is short-lived, it is negatively affected by temperature changes, ultraviolet radiation, air.
2. Mineral wool is a safe and fireproof modern material.
3. Window film is well used as insulation of the glass itself.
4. Silicone sealant is reliable, yet inexpensive.
5. Polyfoam is used to remove cracks in the slopes of windows.
6. Warm mixtures are used outside.
7. Construction adhesive tape is glued over the sealant, which will improve the effect.
8. Facade paint has a high atmospheric resistance. It simply applied to the surface of any shape.
9. Primer dries quickly, easily applied. It is frost-resistant, it does not fear moisture.

When you can not do without a master

A professional is needed when there are obvious defects, and work to eliminate them requires compliance with safety regulations. For repair work it is necessary to call the master, as:

• the insulation of slopes and outcrops from the outside can be dangerous, especially if the window is above the second floor( you can fall and break);
• in order to correctly make the insulation, it is important to know the entire technological process of installation;The
• window is still under warranty.

Thermal insulation of plastic windows for the winter with their own hands

How to compact plastic windows for the winter, a professional will advise. However, there are simple and easy ways with which you can repair yourself. A simple example is the insulation of the window with the use of foam or sealant:

1. Remove the old foam from all the holes around the window. To do this, apply a stiff brush, sticks and brushes.
2. Thoroughly rinse and wipe the surface of the sill and slopes with a cleaner to degrease and remove dust.
3. The resulting cracks should be covered with putty and plaster, then fill with foam.
4. If sealant is used instead of mounting foam, then after its introduction into the gap, it is necessary to seal the top with a construction tape. To carry out the work at hand should be a knife, scissors.
5. Install a heat-saving film. The window box is cleaned of dust and pasted with a double-sided adhesive tape. The film is measured according to the size of the window, then carefully put it and smooth it. To avoid unevenness and bubbles, you need to blow her hair dryer.

Outside

You can make the insulation from the street side in many ways, the façade paint, primer, silicone sealant will do. It is best to use foam polystyrene outside for thermal insulation of the slopes:

1. The foam of the correct size should be pasted onto the slopes, and all visible slits should be covered with glue.
2. On top of the foam, put a special mesh, then plaster it.
3. Align the plaster with a water-repellent layer, apply a primer.
4. Color the resulting slopes, which will create an additional energy-saving protective layer from the wind.

Inside

Thermal insulation of plastic windows inside should be made as carefully as possible using different methods. The thermal insulation will contain the following steps:

1. Insulate the slopes of the plastic windows inside. To do this, apply a mounting foam.
2. Put plastic on top of the peeled slopes.
3. Adjust the fittings. This is done with the help of an eccentric by means of rotation.
4. Replace the seal. This element needs to be changed every 5 years. During this period, he loses its elasticity and begins to let in air.

How to insulate the windowsill of the plastic window

Under the window sill you can often feel the movement of cold air. If a crack is visible, then it needs an notch. It will be good if you attach a piece of plastic under it, and fill the void inside with polyurethane foam or foam foam. Steps for insulating the windowsill:

1. Remove the windowsill.
2. The wall on which it was located is well cleaned of dirt and dust, after which all cracks and problem areas will be visible.
3. Cracks can be covered with a mounting foam.
4. When the foam solidifies, cut off the excess with a knife.
5. All surface primed.
6. Apply sealant to all joints and corners.
7. Plastered.
8. Install the window sill in place.
