When installing PVC windows to keep the heat in the room, as well as to reduce unauthorized air exchange, glazing beads for plastic windows are used.
The glazing bead is a special elongated rod made of plastic shaped profile and equipped with a rubber gasket.
Shtapiki give the windows aesthetic, finished appearance, increase the strength of the entire window system, and extend their life.
The glazing bead on plastic windows is a reliable barrier to drafts, dust, street noise, but, unfortunately, the glazing beads fail and lose their integrity after a while.
In this case, you need immediate replacement of the glazing beads, which you can do by yourself.
Shtapiki differ from each other in form - rounded and ordinary, and in size. For each design of the plastic window, a certain size of the glazing bead is used.
For example, for the installation of PVC windows with a single-chamber double-glazed window, a wide bezel is used, and for a window system with a three-chamber double-glazed window a narrow bead is ideal.
If the construction of PVC windows with four-chamber double-glazed windows, then use a reinforced glazing bead.

When selecting glazing beads, it should be taken into account that they should be in harmony with the rest of the plastic window elements.
Typically, the glazing beads for plastic windows are made of PVC, but more recently, glass composites have been increasingly used for their manufacture.
Glass composite is a unique plastic material, which consists of a filler( quartz, glass fiber, etc.), glass fiber and binder( thermoplastic polymers).
Glass beads from glass composite perfectly store heat in the room, and also resistant to various atmospheric phenomena and external influences.
Thanks to such reliable protectors, window structures are not afraid of any corrosive processes and are not subject to deformation.
How to remove the glazing beads from a plastic window?
Many people ask - how to remove the glazing bead from a plastic window?
The fillets are removed using a spatula or chisel. Pulling out of the window plastic beads, note which of them are left and right, upper and lower.
The process of removing the glazing bead with a spatula is as follows: the spatula is attached to the glazing bead of the large side of the glass and beats it with a palm to wedge the edge of the spatula between the frame and the bead.
Having picked up the middle of the glazing bead, pull it to the center and take out the glazing bead. Further the matter will go much easier, since one of the edges of the glazing bead was free.

Removing the glazing beads from plastic windows with a chisel is almost the same as removing with a spatula.
This requires a flat and wide chisel, a wooden or plastic blade and a non-metallic hammer.
Chisel is installed in the middle of a long bead, or rather - in the gap between the frame and the glazing bead, a little bit in this slot chisel and tilt it to the frame.
With the palm of your hand, they beat the glass unit against the handle of the chisel.
As soon as there is a gap, they insert a suitable wedge in the width and increase the gap.
The released bead is removed, after which the entire removal procedure is performed with the remaining beads.
Buy or make yourself?
Is it possible to make a glazing bead for PVC windows independently and where to buy glazing beads for plastic windows? Let's try to figure out what a glaze is and what it's made of.
The glazing bead is a special made of PVC narrow rails. The rail is made, as well as the profile of the window, but only on other equipment.
Like the same pulling device, the same calibration table and extruder as in the manufacture of window structures made of high-strength plastic, but the output is narrow and thin product, which, despite its weight, securely holds and holds a heavy double-glazed window in the window structure.

The process of making beads from the polymer is as follows: first of all, a solid part of the strip is made, and then soft rubber or PVC is applied to its edge.
The width of the rail depends on the number of double-glazed windows, and the shape of the window shows what it becomes - rounded, rectangular or square.
From this it follows that the production of glazing beads is a rather laborious and responsible business and it is absolutely impossible to produce them independently.
Buy glazing beads for plastic windows can be the same where they bought and PVC windows or in the companies that produced profiles.
The most functional and well thought out is a classic bead, but at the request of the customer, the glazing beads can be manufactured according to individual sizes and shapes.
Install the glazing beads strictly from the side of the room. This is done in order to avoid undesirable encroachments of bad people.
Before acquiring the glazing bead, you need to determine the amount of its need, and then select the desired model of the glazing bead from the catalog and select the desired color.
The cost of the glazing beads depends on the specific profile model, its shape and the manufacturer. As already mentioned, the shape of the staples varies.
Figured beads have a complex shape, so they can cost more than regular beads of a simple rectangular shape.
Sale of glazing beads is made in any city, in specialized companies that manufacture and install plastic windows, where every buyer can get the necessary advice before buying.

In addition, if you do not decide to replace the bezpak with your own hands, then the specialists of these companies will help you with the replacement of the glazing beads.
If you still try to make glazing beads for plastic windows with your own hands, then you may face some problems.
As already mentioned above, the glazing bead - a narrow plastic element, ensuring the integrity of the insulating glass unit.
At home, it's impossible to cut narrow slats, and then laminate them. The slightest error in measurement and ugly cracks in your window are provided.
And if the glazing bead turns out to be wider than it should, the corners of the frame can be torn during clogging. Due to poor quality glazing beads, the tightness of the window will be broken.
