Repair of double-glazed windows with own hands

Remo nt st eklopaketov own it is possible to conduct , if you know their basic structure and the basis of technology for their manufacture.

Immediately need to make a reservation that many users call the glass unit the whole window, including glass, and the frame, and accessories, but this is not entirely true. Actually, the double-glazed window is a design of two or more glasses , which are fastened to the contour with the help of sealants and spacers. Mount it yourself, without the special tool and the - equipment is quite difficult, but it is equally important to properly install the finished double-glazed window into an already standing frame.

Nevertheless , knowing full well that when writing a search request for repair of a double-glazed window, many people have in view all the window block made of PVC and, accordingly, are hoping to get an answer to all the questions, we will expand the topic somewhat. Different nodes and mechanisms of the PVC window will be considered so that the owners are aware of the possible breakdowns that often occur during operation.

The structure of the double-glazed windows in the correct sense of this term is somewhat similar to the design of the aquarium, only "packed" not with three , and from all four sides. The glass package can consist of one, two or even three cameras, as it is designed for installation in different regions with individual climate features.

The chambers are called the compartments between glasses , glasses, respectively, can be installed two, three or four.

Glasses have defined distance, which is determined by a remote metal-plastic or metal strip, on which it is glued from two sides to the sealant.

glasses. This remote rail is of different widths - than it is wider, the more the airspace between the glasses .This structural element is perforated with small holes - they are needed by the so that the inside the chambers does not collect moisture and the windows do not get fogged. The rake can easily be viewed on already installed windows.

Inside the remote rail is filled with a desiccant that does not allow the glasses to fog from inside the cameras, as it absorbs moisture well. The end part of the double-glazed window is filled with - sealant, this layer is 10 ÷ 15 mm.

Professionally made glass block is filled with an inert gas, such as krypton or argon, or dried air with a certain dilution. Gas filling has a greater density than air, therefore such windows have higher characteristics of thermo - and sound insulation.

Glasses of different thicknesses are used for the production of insulating glass, - , this must be indicated in the product labeling.

double-glazed windows

For example, the designation 4- 10- 4 -10 -4 indicates that this is a double-glazed unit with a thickness of at 4 mm, and the distance between them is 10 mm. more complex formula, for example 6- 10-4 - 16 A r - 4 i tells that we have in front of us a special glass unit with an external thick glass, in 6 mm, with the first air chamber of 10mm, medium glass 4mm , gas-filled chamber( argon) in 16 mm and glass with energy-saving effect type "i" 4 mm thick.

Is it possible to assemble a double-glazed unit?

This question often occurs when one of the windows of an installed window unit has been broken. If you approach the assembly process with the utmost care and accuracy, have the right material and tools for work, then it is possible to assemble the insulating glass yourself, although it is not easy to name this exercise.

For work you need to have at your fingertips the following tools and devices:

- remote rails and pads;

- rubber or plastic hammer;

- wide chisel;

- shoe knife;

- special plastic shoulder blade;

- suction cup for glass;

- glass cutter;

- a wooden ruler in 1,0 ÷ 1,5 meters.

Dismantling of insulating glass unit

Before making a new double-glazed window, it is necessary to dismantle the old one with broken glass.

The glass unit is fixed to the in the middle of the frame with the help of glazing beads, and to remove them, they must be dismantled. It is not difficult to do this.

• For this process, a wide and sharp chisel is needed from the tools. Its is installed in the center of the vertical side of the double-glazed window, in the gap between the bead and the frame and gently beat on it with a plastic or rubber hammer.
• When the bead begins to leave the from the frame for a distance of 5 ÷ 7 mm, then it can be disconnected by hand.

• Next, the is on the dismantling the upper horizontal bead of the - , it can be started padding from the corner.
• Next, the removes the second vertical, and then the lower horizontal beads.
• To pull the double-glazed window out of the frame, you need to put dense gloves on your hands, since it can have sharp edges, and the 's likelihood of seriously injuring .If one of the glass is broken, then the glass unit can be pulled out using the suction cup, by setting to its in the middle of the whole glass.

• The suction cup is installed on the glass, fixed, and then behind the its handle needs to gently pull the double-glazed window onto itself and pull it out of the frame.

Self-made insulating glass unit

The following materials are needed for the manufacture of a double-glazed window:

- glass of the required thickness( at least 4 mm);

- spacer or spacer;

- primary sealant( butyl) and secondary( polysulphide . polyurethane);

is a free-flowing desiccant.

Work on manufacturing consists of several stages. The first of these, of course, is the preparation site for the holding.

• For the convenience of the process, will require a reliable , a fairly large table, with a perfectly flat surface, covered with a dense soft material such as felt.
• Further, the glass is measured. measure the is taken from the old glass unit, and if this is not possible, the inner edges of the frame are measured vertically and horizontally, minus 1 ÷ 2 mm in each side.

• The cut on the glass should be ideal, so you need to buy a good glass cutter that can easily cope with this task.

• If glass is required large enough, then to fit it to the desired size, it is best to use the roller .
• Prepare the in the for everything you need, put the glass on the table, transfer the measurements to it, and install the fast-cutting .Its roller version is convenient in that it makes it possible to make a perfectly smooth cut, since the stop will not allow the cutting element to slip.

• The edges of the cut glass are recommended to carefully trim the bar with an abrasive surface( "diamond dust"), which will help to save your hands from damage.
• When the required glass is cut and the image is processed , it needs to be rinsed well, and the still better than the - treat the with a windshield wiper. Especially carefully it is necessary to work on the internal surfaces of the glass, because then they will not be able to clean.
• The next stage of the is the preparation of the remote rails. You can try using rails from the old double-glazed window, cutting them off the glass together with the sealant, but you will need to completely free them from the deposited on the masses. If this can not be done due to damage to one of the sides, then the dimensions of the - are quite realistic, and it's easy to make a new frame from perforated racks on them.

The frame should be smaller than the glass size for the 4 - 7 mm, that is, the glass should go beyond the of its edge. This distance will subsequently be sealed with a secondary sealant.

• The inner cavities of the perforated spacer frames are filled with a desiccant for three quarters, the most commonly used is granular silica gel.

• To prevent the from falling out on the other hand, the immediately installs a special corner into the rack cavity, which will become a connecting element and will help to get an ideally right angle from the vertical and horizontal slats.

• After mounting two separate rails, you should get an angle of 90 degrees.

• rails butyl tape is attached to the ends of the frame with a protective film , which will be removed before fastening glass to .

• On the prepared, ideally clean table the glass is laid, on which it is necessary to paste a ready frame precisely. Here you can resort to a small trick of - on the glass on the ruler with the help of a corrector to make marks of the overlapping of the frame, on its outer side - then these marks will be easy to erase.

• Before placing the frame on the glass from the adhesive tape, the protective film is removed from the bottom. The frame is set strictly on the marks and slightly pressed to get a fixation.

• is opened. It is recommended to make the same marking on the glass, which will be glued on the top of the frame, since the glass differs from the frame in relation to the frame, is unacceptable. The edges of glasses should protrude beyond the edges of the frame identically.

• The upper protective layer is removed from the sealing tape, the second glass is precisely aligned with the frame on the marking.
• If it is conceived to make a two-chamber package, the procedure ss pr is repeated.
• When all the glasses are assembled in a double-glazed window, it is necessary to carefully cut the glass to form reliable clutch with butyl tape - this will be the primary sealing circuit.
• The next step is filling the remaining cavity between the glass around the perimeter of the insulating glass unit with polyurethane, thiacol or polysulphide - thereby forming a second sealing loop.

This prozest ss pr is carried out using a spatula or building syringe . The sealant must completely fill the cavity without any small air cavities and cracks.

The drying of this circuit usually lasts 8 - 14 hours, and after hardening it should be similar to rubber. Then is smoothed and the quality of congealing and filling is checked.

Installation of insulating glass

• Now remains only to install the double-glazed window in the frame. In order that the glass does not touch the with the rigid frame material, a rubber seal on the entire side on the one side is installed on the entire perimeter.

• Further, on the vertical walls and on the horizontal base of the frame, the rubber pads - are laid to soften the contact of the end faces of the glass with the plastic of the window profile.

• Then, the ready-made double-glazed windows are installed in the frame on the pads, leveling it according to the level.

• The pack should be pressed with glazing beads, having pre-installed a rubber seal in them.

• The bezel is clogged in the groove with a rubber or plastic hammer, which can not damage the plastic surfaces.

Typical breakdown of PVC windows and how to fix them

During the operation of the window, various breakages of the installed hardware can occur, which leads to the difficulty of the functioning of its various components. Therefore, efforts must be made to restore their normal work. The most common malfunctions are:

- sagging of the flaps;

- violation of the press function of the sash;

- replacement or repair of the handle;

- replacement of the sealant in the event of a violation of normal sealing;

- the opening of the wing at once in two positions.

Elimination of most of these shortcomings, rather, can be called regulatory actions, rather than repair, but how they are carried out it is still worth knowing the to all , who have PVC windows. For this work, the tools will need screwdriver , screwdriver , hexagon key size of 4 mm.

1. Adjustment to the of the vertical.

To adjust the vertical position of the flap by lowering the of its or raising it, the first thing to do with the - is to remove the decorative plastic cover from the bottom hinge. Further, in the upper of its adjusting groove the hex key is installed and rotated to the right, if the needs to raise the leaf and to the left, if its needs to be omitted. The key rotates gradually, and after each turn of the flap, the is required to open and is closed by to evaluate the adjustment result.

2. Adjusts the lower corner of the flap to the horizontally.

If the sags one of the lower corners of the leaf, the same lower canopy is used for adjustment, only adjustment is made using the side adjusting screw. Turns are performed to the right or left, depending on which of the corners is required to align horizontally.

3. Horizontal flap adjustment with of its slack.

If necessary, adjust the horizontal position of the flap when the is in its sag, an adjusting groove is placed at the top of the frame from the shed side. The hexagonal key rotates in the same way as the above adjustments, with an obligatory intermediate check of each action of the - closing the and by opening the gate until it is pulled to its normal state.

4. Adjustment of the leaf clamp.

Adjusting the clamping of the leaf when inflating, or when moving from summer to winter mode and vice versa, is performed by changing the position of the eccentric pivot pin.

This element is located on the front side of the window, and the process of its adjustment is also made by hexagon.

is responsible for the degree of clamping. The position and the shift of pins can be clearly seen in the figure, in different versions of their execution.

A weak or normal leaf clamp is installed for the summer period, and a strong clamp - for the cold season.

5. Adjusts the sash with a shift to the right or left.

Adjustment of the "left - to the right" of the flap bottom is carried out in the open its state, through the groove located on the inside of the shed. Turning the key to the left - leaves the door to the right, and vice versa. Verification is also conducted after each turn.

6. It happens that when the door is opened, the door is in the folding and swivel position at the same time. This often happens if the frame is installed with the opening in two positions.

If this happens, you need to install the flap vertically and press the upper part of the frame to the canopy .Without closing completely, you need to set the handle horizontally, so that it would be turned in the open position of the leaf.

If the handle lock installed on the end of the door, not the gives the its to turn, it needs to be corrected with a finger. Next, you need to close the sash, as usual, turning the handle down. Then, you just need to open and close the flap in different positions of the - , it should stand on its on the and work in its normal mode.

7. Jamming of the

handle If the jammed the leaf handle in the open its position , must be disabled the lock that is installed to prevent the from breaking the window, when reinstalling it in different positions , if proc ccpr goes too fast. When you open the window in the flip position, the lock is triggered and not the gives the a rotary knob.

Lockers from of different firms have different , but is basically , to deal with them, you do not need to perform complex operations. It is usually sufficient to press this element against the seal or to fix with a finger, and at the same time turn the handle.

In other cases, the blocker, for various reasons, can slip past the response mechanism. In order for the to solve the problem in this case, it is necessary to find on the end of the flap the very mechanism for which the lock was to be hooked. Then unscrew the screws on the and arrange a thin plastic lining underneath it. After that, you need to check its operation. Usually, such a gasket is enough to allow the clutch to pass normally.

8. Changing the handle

Removing the old handle and installing a new one is done if this item has disappeared, loosened, or it needs to be replaced with another one, for example with a built-in lock. Such an improvement is simply necessary if the apartment has a small child .And to make the replacement of - is quite simple.

To do this, open the screws with which the handle is bolted to the frame. They are hidden under a decorative plate located under the handle. Turning its , open two screws for a figured screwdriver .

After unscrewing them and pulling the handle on itself, it's easy to dismount its .On its place is new, and the can be screwed on its with the same screws.

Next, the decorative plate turns into place - and work on this is completed. As can be seen from the description, it is very simple to perform the replacement process - it is quite affordable for anyone who knows how to use the screwdriver .

9. Difficulty turning the handle

Fixing the handle can occur for various reasons, such as skewing or sagging the sash. In addition, the old sintered lubricant in the swivel mechanism can become the cause.

Start with the simplest process - with the lubricant, which must be applied to the rotary mechanism and turn the handle to one side and the other. The lubricant is applied from a cylinder having a thin tube, so the composition will reach the farthest corners of the serviced unit. The should be applied from the front of the frame.

If nothing has changed, then is possible it is necessary to adjust the leaf, but first you need to determine which side should be adjusted. To do this, its is closed and determined by eye, and adjusted according to the above instructions.

10. Replacing the seal

Another is one event that must be carried out when a draft appears. Often this becomes possible due to the fact that the seals have become obsolete, lost their elasticity and ceased to function normally.

Sealant, on average, is about 7 ÷ 10 years, but if it started to dissolve or crack appeared on the surface, then it's time to replace it.

First you need to measure the length of the old seal to know how much it will need to be purchased.

When a new seal is already purchased, the old one is removed from the grooves. The grooves must be thoroughly washed and dried. Then, they start the seal and press it against the stop. It can not be stretched or compressed - it must be in its natural state.

11. Correcting the skewing of the

Insulating glass Another one possible drawback is the with in the profile of the installed frame. How to fix it - is clearly shown in the attached video:

All repair work, and even more on the adjustment of the plastic window can be done independently, saving a decent amount, but for thisIt is necessary to have free time and opportunities. However, if there is absolutely no idea how to work with tools and with the mentioned materials, then it is better to entrust this process to masters who have repeatedly faced similar problems.
