The hero of my story

The glazing bead is one of the key elements of any window, and at first glance it is invisible. But take a closer look and you will see characteristic strips located along the edges of the frame. Wooden glazing beads for windows can be made from different types of wood, while plastic ones are divided depending on the manufacturer. Today I will tell you what all these parts are, how to choose the right ones, and also consider their installation.

Types of glazing beads for plastic windows

The main purpose of these unnoticeable parts is to hold the glass in the window frame itself. The glazing bead also acts as a decor, giving the window additional aesthetics. Previously, various putties and other sealants were used for this task, but with the advent of glazing beads they have sunk into oblivion, and plastic windows without these products do not exist at all.

But do not forget about another important property of this product - insulation, thanks to which the window becomes completely airtight . The price of these parts varies, and it all depends on your requirements.

Tools and materials

• Glass. You can immediately order glass cutting in a workshop, or you can cut it yourself. You should be especially careful with old glass that has been lying around for several years - various deformations will have already affected them and it will be difficult to cut them.
• Glass cutter.
• Glass cutting table. The dimensions of its lid must be no less than the dimensions of the glass itself. It is very important that the surface is as flat as possible. Additionally, you can put an old blanket or cloth on the surface. Zenzubel is a type of planer for cutting grooves
• Chisel. Will be used to dismantle the old bead. Width – 1.5-2 cm.
• Hacksaw for metal.
• Roulette.
• Nails 2-3 cm long. It is recommended to use copper-plated ones - they will last longer.
• Window sealant.
• Insulating tape.
• Pliers.
• Zenzubel.
• Marker or other marking tool.

approximate price

Wooden glazing beads are sold in the retail chain by linear meters, their cost depends on the material of manufacture, section shape, thickness, manufacturer and distributor, the approximate price of popular varieties:

• Linden semicircular wooden glazing bead 10x10 mm - wholesale price 4 rubles. per linear meter.
• Semicircular window glazing bead made of pine, spruce, linden with a cross-section of 10x10 mm - average retail price 10 rubles. per linear meter.

The market widely presents various types of wooden window beads made from various types of wood, domestic and foreign, differing from each other in profile, dimensional parameters and cost. Self-installation or replacement of wooden glazing beads will not be difficult for any owner without carpentry skills - for this you will need the simplest household tools and knowledge of simple installation technology.

Removing old glass

At the initial stage of dismantling, it is necessary to remove the old fastener . To do this, use a chisel, the sharp end of which is carefully inserted between the glass and the bead. This should be done close to one of the nails. You can start from the corner or from the middle of the bead.

The bead is dismantled using a chisel

After this, you should carefully turn the chisel to insert it as deeply as possible under the glazing bead. All that remains is to use it as a lever to remove the old fastener. Sometimes the glazing bead breaks at the attachment point (especially if it is old and rotten). In this case, it will need to be broken out piece by piece. The nails that ultimately remain in the frame are removed with pliers.

Kinds

Wooden window glazing bead is divided into types according to the following characteristics.

1. According to the material of manufacture. The material of the slats is selected for the window from the same type of wood. Products are made from the following types of wood: coniferous (pine, larch, spruce), deciduous (oak, beech, ash). For expensive wooden structures, mahogany is made to order.
2. According to the shape of the product. Standard types are semicircular, rectangular, concave. For decorative or furniture purposes, there are figured and carved types.
3. By section size. The standard dimensions of the glazing bead are a section of 10 by 10 millimeters. The length varies from 1 to 2 meters.

Most often, meter-sized products are found on sale. Currently, they have begun to produce products with a groove for rubber insulation.

Glass size measurement

Window glass is not always rectangular, so simply measuring the height and width may not be enough. Experts proceed in a different way: they measure parameters on both sides and, if strong curvature is noticeable, then in the middle. To measure, use a special meter or tape measure; do not try to take measurements with a short school ruler - the result will be inaccurate.

The easiest way to take measurements is with a tape measure.

After this, you should measure the diagonals of the glass. Most often, the difference in size will be small - within 1% or 1 cm. In this case, you can ignore it and simply cut out a rectangular piece with the given parameters. If the difference turns out to be greater, then you won’t be able to discount it - be sure to take into account all the parameters when cutting. An important point: most often the glass is cut into slightly smaller (literally a few millimeters) sizes . This will avoid a number of installation problems without creating drafts.

Tips to help

The first recommendation concerns the temperature suitable for this work. It is better to remove glazing beads in the warm season. In winter, plastic strips “tan”, so even with careful actions they are easily damaged. Possible element defects include cracks formed at bending points.

1. Numbering of all glazing beads is mandatory, since the planks only look exactly the same. A difference of even 1-2 mm will be noticeable at the joints if the slats are accidentally mixed up.
2. It is not recommended to keep the dismantled planks suspended for a long time; it is also not recommended to place them “in a corner” vertically, as they can become deformed. Therefore, a convenient place for them must also be provided in advance.
3. Some craftsmen use an unusual tool for removing plastic beads - an ax. If you have experience in handling it, then the operation can be performed successfully. For beginners, such “heavy artillery” is not recommended.

Since removing the glazing bead from a plastic window is not particularly difficult, some owners decide to do this work without much thought. Yes, this process is understandable and quite simple, but it requires a careful approach and adherence to the rules. If you are not sure that the operation will be successful, then it is better to seek help from experienced people. Lack of skills can play a bad role: without experience, it is easy to damage the components and the plastic frame itself.

A video on how to remove a glazing bead from a plastic window will give you the opportunity to get to know the process better:

Glass cutting

The easiest way is to order ready-made glass in a special workshop, then all that remains is to think about its transportation. On the other hand, if there are old stocks, then you can trim it yourself. If you don’t have such experience yet, you can practice on some scraps. Over time, you will be able to determine from one sound whether the glass has cut through or not.

Cutting glass requires some skill

If you plan to trim a fairly wide strip, you can break it off by hand, without additional tools. The only point is that you should not forget about protecting your hands; ordinary gloves can protect you from very serious cuts. After you have gone through the glass with a glass cutter, you will need to move it to the edge of the table so that the cut strip protrudes about 1 cm. For greater reliability, you should tap the cut area from below. Then, with a sharp movement, press down from top to bottom, trying to bend the glass.

A little advice: you can use a wooden block or a flat board as a ruler, but it is not recommended to use metal objects. Before starting work, you should thoroughly clean the cut area from dirt.

Removing blockages

Sometimes the fittings of a plastic window do not work correctly. The first time this happens, it appears that the window is broken, although this is usually not the case. This situation cannot even be called a repair. We just need to get everything back to working order.

The handle does not turn

Sometimes, in some position, the handle of a plastic window “gets stuck” and does not want to turn. Usually the reason is the activation of the blocker. This is a plate that is located near the handle on the side of the frame. The shape of the plate varies among different hardware manufacturers.

Types of blockers on PVC windows

To correct the situation with the handle, you need to return the lock to its normal position. If it is in the form of a long plate, press on the moving part and place it vertically, then turn the handle. Then everything should work fine. Sometimes a plastic window blocker looks like a small tongue. We also press on it and turn the handle to the required position.

If this “treatment” does not help, you need to check whether the blocker fits into the mating part (pictured above). Sometimes, due to heat or cold, inconsistencies begin. If the tongue does not reach the mating part, you need to move it a little closer. The counter plate is unscrewed (there are two bolts), a plate the size of the counter part of the blocker is cut out of white thin plastic, and it is installed between the frame and this plate. If the plastic sticks out somewhere, carefully trim it with a sharp knife. The window should now close.

The sash hangs only on the bottom hinge

This situation occurs if the window is opened in both tilt and tilt modes at the same time. Don’t panic, leaving the sash open, we press the top edge against the frame. Having aligned the top edge with the loop, turn the handle to the “open” position - horizontally. If it does not turn, turn off the blocker.

The plastic window fittings did not work correctly

Close the sash, turn the handle down to the “closed” position. Slowly check the operation in all positions. There are still a lot of nuances associated with blowing from under the window, but all of them are solved mainly through adjustment, and how to adjust a plastic window is written here.

We have described the most common problems with plastic windows, which you can solve yourself without involving specialists.

Frame check

An important stage, but for some reason missed by many. In some cases, the quarters chosen for glass turn out to be uneven - there is a difference in depth. If the difference is minimal, then it’s okay, but in more serious cases the glass may simply break. To avoid such troubles, the frame needs to be trimmed. A tool called a zenzubel or folding hebel is used for this. You can try to get by with a regular plane, but then you will have to finish the corners with a chisel.

PVC beads

Beads for PVC windows are made from the same plastic as the main profiles for assembling sashes and frames.
They should have the same exact snow-white color. At the same time, some manufacturers, in an attempt to save on components, use glazing beads made from recycled materials to fix double-glazed windows. This is unacceptable, since such elements have a grayish tint and are of poorer quality. Read more about the requirements for polyvinyl chloride on OknaTrade. Structurally, plastic window beads are a strip that is hollow from the inside. Thanks to the presence of an air chamber, it is possible to further reduce the heat exchange between the street and the interior. The length of such profile elements is usually 6.5 m. Depending on the modification, the glazing beads are equipped with 1-2 sealing contours made of elastic materials. According to the profile cross-section, these elements of window structures are divided into:

• square;
• rounded;
• flat;
• beveled;
• curly.

For fixation in frames and sashes, the glazing beads have a special structural protrusion that fits into the profile and snaps there. That is, the manufacturers of PVC systems in this case used a classic and reliable tongue-and-groove lock. Plastic glazing beads differ not only in the shape of the profile section, but also in dimensions. When assembling window structures, they are selected depending on the installation depth of the frames and the selected double-glazed windows. If single-chamber models are used to complete windows, they are secured with wide glazing beads. To fix two- and three-chamber double-glazed windows, narrow slats are used.

In the basic configuration, windows are usually equipped with glazing beads with a rectangular cross-section. If you need another form of transition from a profile to a double-glazed window, you need to discuss this nuance with the manager in advance.

Fitting the glazing bead

It's time to prepare the mount. The glazing bead is cut with a hacksaw and is most often done so that an angle of 45 degrees is formed at the ends . Most often, a miter box is used for marking, but instead of it, a regular construction corner can be used with equal success. In addition, those who wish can quickly make a miter box on their own from a couple of bars.

Use a miter box to cut glazing beads at an angle of 45 degrees.

All that remains is to mark the required length on the glazing bead and saw off the pieces. Experts recommend cutting on one side, then trying the material into the frame, marking the new length there and filing it. Note that a properly sawn glazing bead will stay in the frame even without nails (albeit not very firmly).

In order not to confuse the pieces later, they can be marked. Also, to simplify the process, nails are pre-set. Some people prefer to drill a hole for them, but most often installation does not require this.

How to remove a bead from a plastic window: replacement instructions

Plastic windows made from PVC profiles are very popular among the population due to their low cost and excellent physical characteristics; sometimes during operation it becomes necessary to remove the glass unit for various purposes.
When carrying out dismantling operations with your own hands, the user should know how to remove the glazing beads from a plastic window on their own, because this is the only way to remove the double-glazed window from the opening. Although the procedure for removing a window bead from a plastic window does not look complicated and almost any housewife can handle it, knowledge of some features can be useful to everyone. In addition, carrying out further operations with double-glazed windows requires certain skills and deeper knowledge in the field of window glazing.

Glass installation

Now you can install the glass. Before installing it in the frame, a quarter around the perimeter is coated with putty - special window putty or simply acrylic-based sealant . After applying it, glass is inserted into the quarter. It is very important to press down a little so that the putty comes out a little. If there is too little, you can add it on top, coating the perimeter again. After this, the glazing beads are nailed - they should be pressed tightly against the glass. To avoid damaging it during installation, it is recommended to wrap the hammer with a couple of layers of electrical tape.

The glass is inserted into the groove, which is pre-lubricated with sealant

As you can see, replacing glass in a wooden window is not the most complicated process. However, all of the above applies only to single glass. Installing wooden frames and double-glazed windows is a completely different matter. Here, most likely, you cannot do without a specialist.

How to choose

Wooden glazing beads seem to be an insignificant element, but the choice must be made with the utmost attention. This small detail ensures the tightness of the window unit. If treated carelessly, the product will soon cease to perform its functions and become unusable. Moisture and drafts will penetrate through the resulting cracks.

This is an extremely important point for external doors facing the street. The tightest possible fit to the frame structures is the main criterion. It is better to stay with ordinary smooth slats.

For internal ones that are not in contact with manifestations of the external environment, you can give preference to products with carvings or other decorations. Decorative strips must correspond to the overall style of the structure and interior.

Fastenings are also important - they should not be visible visually. After all, a window should not only perform direct functions, but also be beautiful and aesthetically pleasing.

Process:

1. Clean the fold from any remaining glass and debris. The window frame must be clean and dry. 2. Cut out the glazing beads, adjusting them exactly to the size of the window opening. 3. Apply sealant around the perimeter of the rebate to a third of its depth. Gently press the glass to ensure a tight seal. 4. We nail the glazing beads into place over the sealant, recessing the heads of the nails into the wood. To avoid accidentally breaking the glass, place a sheet of cardboard or plastic on it in this place. Please note: the inner edge of the glazing bead must be adjacent to the glass without a gap - otherwise the window will rattle from the wind and allow cold to pass through. 5. Wipe off any excess sealant. The window is ready!

Cosmetic repair of wooden windows

Elimination of local damage. For example, fungal damage to part of the window frame.

• identification of the damaged area. To do this, you can carry out a small test: with an awl you need to push through dilapidated or suspicious areas of the frame; if the tip easily falls through, then the wood is damaged;

• cutting off the unsuitable layer;

• the cleaned area is dried. To do this, you can use a hair dryer or a fan heater (be careful with glass, direct the air flow directly to the wood);

• applying wood hardener and preservative;

• applying putty. Layer thickness - according to the instructions. If you need to apply several layers, you need to wait until the first one dries well;

• window painting.
