None of us is immune from trouble and at one moment the glass in the wooden window of your house can break. In such a situation, the question arises of an early repair, but many experience certain difficulties with this. So, how is the glazing of a wooden window made?

Tools and materials

Removing old glass

On initial stage dismantling, it is required to remove the old mount. For this, a chisel is used, the sharp end of which is carefully inserted between the glass and the glazing bead. This should be done near one of the nails. You can start from the corner or from the middle of the glazing bead.


The dismantling of the glazing bead is carried out using a chisel

After that, you should carefully turn the chisel to insert it as deep as possible under the glazing bead. It remains only to use it as a lever to remove the old mount. 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 in parts. The remaining nails in the frame are removed with pliers.

Not always window panes are rectangular, so just measuring the height and width may not be enough.. Specialists act in a different way: they measure the parameters on both sides and, if a strong curvature is noticeable, then in the middle. A special meter or tape measure is used to measure, do not try to take measurements with a short school ruler - the result will be inaccurate.


It is most convenient to take measurements using a tape measure.

After that, the diagonals of the glass should be measured. Most often, the size difference will be small - within 1% or 1 cm. In this case, you can ignore it and simply cut out a rectangular piece with the specified parameters. If the difference turned out to be greater, then it will no longer be possible to discount it - be sure to take into account all the parameters when cutting. Important point: most often glass is cut a little smaller (literally a few millimeters) in size. This will avoid a number of installation problems without creating drafts.

glass cutting

The easiest way is to order finished 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 cut it yourself. If you do not have such experience yet, then you can practice on some scraps. Over time, by one sound, you will be able to determine whether the glass has cut through or not.


Cutting glass requires some skill

If you plan to cut a sufficiently wide strip, then you can break it off with your hands, without additional devices. The only point - do not forget about protecting your hands, ordinary gloves can protect you from very serious cuts.. After the glass has been walked on with a glass cutter, it will need to be moved to the edge of the table so that the cut strip protrudes by about 1 cm. For greater reliability, you should tap on the cut from below. After a sharp movement, you should press from top to bottom, trying to bend the glass.

A little tip: as a ruler, you can use wooden block or a flat board, but metal objects application is not recommended. Before starting work, thoroughly clean the incision site from contamination.

Frame check

Important, but for some reason omitted by many stage. In some cases, the quarters selected under the 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 can simply break. To avoid such troubles, the frame needs to be trimmed. For this, a tool called zenzubel or foldedgebel is used. You can try to get by with an ordinary planer, but then you have to finish the corners with a chisel.

Size check

The next step is to check the dimensions. We insert glass into the window opening. If it enters well, then you can proceed to the next stage. If a search of 1-2 mm is noticeable, then it can be eliminated with the help of the previously mentioned zenzubel. If the glass turned out to be smaller than the opening, and significantly, then you can additionally make thin linings in the right places.

Bead fitting

It's time to prepare the mount. The 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 an ordinary building corner can be used with equal success. In addition, those who wish can quickly make a miter box on their own from a pair of bars.


A miter box is used to cut glazing beads at an angle of 45 degrees.

It remains only to mark the desired length on the glazing bead and saw off the pieces. Experts recommend trimming on one side, then trying on the material in the frame, marking the new length there and filing. Note that a competently sawn glazing bead will stay in the frame even without nails (albeit not very tightly).

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

Glass installation

Now you can install glass. Before installing it in the frame, a quarter around the perimeter is smeared with putty - a special window or simply acrylic-based sealant. After its application, glass is inserted into the quarter. It is very important to put some pressure on it so that the putty comes out a little. If it is too small, you can add it on top by smearing the perimeter again. After that, the glazing beads are nailed - they must be tightly pressed against the glass. In order not to damage it during installation, it is recommended to wrap the hammer with a couple of layers of electrical tape.


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

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

The last stage of glazing is the installation of glazing beads, which can be made not only from wood, but also from plastic. It would seem that such a simple and inexpensive window element, but how much benefit it brings. For example, it removes moisture from the glass, preventing it from getting on the main frame, and also insulates the room by closing the gaps between the glass and the frame. Today we will look at wooden glazing beads for windows made of wood and PVC.

You will learn:

  • what it is;
  • how they differ from each other;
  • how to properly install and manufacture.

What is commonly referred to as a bead

So it is customary to call a rail made of wood or PVC, having a small cross section, where one plane is designed to remove moisture. They can mainly be found as fastening glasses in door and window frames.

If you remember, earlier in this place there was always a putty that did not let moisture through, but now it is practically not used. Came to replace silicone sealant, which has proven itself both from the inside and especially from outer side.

Tip: use a colorless sealant in your work, which is almost invisible from the outside, like colored or pure white.

Kinds

Consider two main options that can be used for wooden windows, it's from:

wood
  1. Usually used in individual and civil buildings.
  2. They are usually made from trees. conifers. Although, they can be from larch, and even exotic ones.
  3. Trading networks offer products 2-3 m long.
  4. The profile of the product is more conservative than that of plastic.
PVC
  1. Differs in ease, reliability, plasticity and durability concerning wooden.
  2. Does not require painting prior to installation.
  3. Washes off dirt and dust quickly.
  4. It is usually sold by a trading network with products 4 m long, it can be offered individually or in packs of several dozen pieces.
  5. Has several ways of fastening.
  6. Plastic glazing beads for wooden windows are more diverse.
  7. The dimensions of the sides depend on the thickness:
    • double-glazed window;
    • glass;
    • sandwich.

They can be 5-30 mm.

Tip: if you need to get a rounding on one of the faces, go through its radius beforehand.

In this case, the manufacturing cost will be 5-10 times lower than if you buy the product in a store or on the market. Just keep in mind that the wood must be dry and not have knots, otherwise the glazing bead on them will break.

Tip: paint should be applied to the product before installing it on the window.

Installation

Prepare:

  • tube with silicone;
  • construction pistol;
  • nails, preferably finishing;
  • lightweight hammer.

Process:

  1. Cut off the spout from the tube to a certain diameter and install it in the gun. Gently pressing the trigger of the device, coat the perimeter of the window so that a roller Ø3-4 mm remains on it.
  2. Attach the glass to the frame and lightly press down, removing the gap between it and the silicone layer.
  3. Attach a pre-prepared glazing bead to the glass, remembering to fill it with nails. The latter should be parallel to the glass, and not at an angle to it, otherwise there is a risk of breaking it at the time of clogging.

Tip: use galvanized nails of minimum length or finishing nails that do not have a hat.
The price of the latter is about 20% higher.

It is better to use a special hammer - glass. During operation, its one surface must be leaned against the glass, then it will definitely not crack.

Tip: do not forget that the glazing bead should always be installed on the outside of the window, then moisture will not penetrate into the room.

If you ever have to delete broken glass from a wooden window, remove the glazing bead like this:

  • take flat metal tool, for example, a knife, hammer, spatula, pliers, chisel or screwdriver;
  • pry the middle of the glazing bead by inserting the tool near the hammered nail;
  • thrusting the second tool into the slots that appear, wring it out completely, and then remove it from the window.

Conclusion

From the article proposed above, it became clear that the glazing bead is a necessary structural element of any window. It allows you to protect the frame from moisture, and also will not allow cold air to enter the room. The video in this article will complement the information on the above topic.

From the article you will learn:

Shtapik plays important role V plastic window. It depends on him whether the light-transmitting system will fully protect the adjacent room from the penetration of dust, noise and draft into it. Without a properly installed glazing bead, the window will be a structure that closes the opening of the room only from strong gusts of wind, while not being able to maintain heat at the proper level.

Sometimes the glazing bead (represents an elongated rail) needs to be dismantled. Most often, the reason why the rail must be removed is the replacement of a broken double-glazed window. Consider given element plastic window details.

What is a staple?

The figure below clearly shows what a bead is. For a tighter fit to the wall of the double-glazed window, it is equipped with a sealing rubber. Beads differ from each other in size and shape.

They can be:

  1. curly
  2. round
  3. square

A wide bead is used in double-glazed windows that have only one chamber in their composition, while a narrow bead is designed for a three-chamber double-glazed window.

The composition of the glazing bead is polyvinyl chloride (PVC). However, the latest window models, as a rule, are equipped with similar elements, which are based on glass composite, which differs from plastic (PVC) in better properties.

Why does a window need a bead?

The glazing bead keeps the double-glazed unit from falling out, and it is attached only from the inside of the window, there is no need for a rail from the outside.

Such an element prevents the penetration of dust, drafts, street sounds into the room; complements by making her appearance aesthetically complete.

The glazing beads themselves rarely need to be replaced, only in case of significant damage, or if they lose their original properties.

How to remove a bead from a plastic window?

To remove the glazing bead with your own hands, you do not need to be a "jack of all trades", it is enough to be able to use a hammer, spatula and chisel. To remove each glazing bead (and there are 4 of them in each sash: two vertical and two horizontal) for an unprepared person, it will take 3-5 minutes, no more.

Bead removal sequence:

  1. A chisel or spatula with a sharp end is placed in the gap between the glazing bead and the frame (closer to the middle).
  2. By pressing the tool like a lever (a hammer to help), we are trying to raise the glazing bead.
  3. We intercept the freed part with our hand and carefully remove the rail of interest.
  4. We put the bead aside so that when installing it back, it will not be confused with another.
  5. In the same way, we dismantle the rest of the elements.

For more information on how the window glazing bead is removed, see the videos below.

It should be remembered that the top rail of the plastic window is removed last, and during subsequent assembly it is installed first.

Glazing beads for plastic and wooden windows differ fundamentally only in the material of manufacture and the cross section of the profile. Regardless of the type, these elements perform important functions - they fix the double-glazed windows in the light openings of door and window blocks and complete the sealing procedure for the frames. In addition, glazing beads decorate windows, since they create an area of ​​​​smooth transition from the main profile to the glass. They also close all the gaps between double-glazed windows and sash frames.

PVC glazing beads

PVC window glazing beads 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 recycled glazing beads 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 at WindowTrade.

Structurally, plastic window glazing beads are a hollow rail from the inside. Due to the presence of an air chamber, it is possible to further reduce the heat exchange between the street and interior spaces. 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 section, these elements window structures are divided into:

  • square;
  • rounded;
  • flat;
  • bevelled;
  • curly.

For fixing in frames and sashes, the glazing beads have a special constructive ledge that enters the profile and snaps into place. That is, the manufacturers of PVC systems in this case used a classic and reliable thorn-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 mounting depth of the frames and selected ones. If single-chamber models are used to complete windows, then they are fastened with wide glazing beads. For fixing two- and three-chamber double-glazed windows, narrow rails are used.

IN basic configuration windows are usually equipped with rectangular glazing beads. 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.

Beads for wooden windows

Wooden glazing beads for windows are solid slats, which, by analogy with plastic ones, can have a rounded, rectangular, figured and beveled profile section. For their manufacture, the same type of wood is taken that was used in the production of Eurobar. Since it is in the installation area of ​​the glazing beads that the most condensate accumulates, the slats must be carefully treated with antiseptic impregnations. This procedure is necessary to slow down the processes of wood decay. Before installation, glazing beads, like all other elements of window structures, are covered several times paints and varnishes and polished.

In the manufacture of windows from eurobars, double-glazed windows in the light openings are fixed somewhat differently than in models made of plastic. To fix them, carnations with invisible caps are used. They are hammered through the rail into wooden profile almost close to the glass in that area of ​​​​the glazing bead, where a special recess was made for the sealant. This procedure can be performed only with the help of a special pneumatic or electric hammer, reminiscent of the principle of operation of a stapler. After fixing the glazing beads around the perimeter of the light openings, all the cracks are sealed with transparent silicone, the excess of which is then removed rubber spatula and a special wash.

Replacing glazing beads in a plastic window

Although in theory plastic glazing beads are designed to be the same as the frame structure, they can loosen prematurely. This is due to the unequal thermal expansion different elements frames, as well as exposure to condensate and ice slats. To prevent possible depressurization of the window, it is necessary to replace the glazing beads in time. This procedure can be performed both with the help of a wizard, and on your own. With self-replacement, you will need an accurate angle cutter, a metal spatula, rubber mallet, measuring tool and a pencil. In the process of performing this procedure, you must adhere to the following algorithm of actions:


It is recommended to start dismantling the mounting rails with the longest elements. Most often, these are vertically arranged glazing beads. During the entire procedure, you need to make sure that the double-glazed windows do not fall out of the opening. When there is not enough experience, it is better to invite a specialist window company.

Replacing glazing beads in a wooden window

Buying glazing beads for is not a problem. They are sold in almost every hardware store. However, it is unlikely that such products are suitable for eurowindows, so in any case you will have to contact specialists. In addition, due to the lack of a special hammer, it will not be possible to drive in cloves imperceptibly. If this is done conventional tool, you can damage the double-glazed window, therefore, in the case of wooden euro-windows, it is recommended to immediately order the service from the masters.

Installation of glass on glazing beads

Glazing beads are mainly used for a more aesthetic design of bindings with outside. In addition, they firmly hold the glass. Beads should be carefully oiled or painted and dried before use. After installing the glass, attach the glazing beads to the folds and nail with studs and nails. Studs and nails should be driven in so that they do not touch the glass, otherwise the glass may break.
