What it is?

Glazing bead is an integral part of a window (and not only plastic, but also glass, old-fashioned), which the window owner often does not even know about. It is impossible to see it from the outside, since it is attached from the inside to avoid unwanted penetration into the apartment through the window (by removing the glazing bead, you can easily remove the glass unit itself). But even indoors, it merges with the plastic frame and is not particularly noticeable. Thanks to this, it gives the window the appearance of completeness, integrity and aesthetics.

And yet, the main function of this inconspicuous part is to secure the glass unit in the frame. Thanks to the glazing bead, the tightness of the glass unit is achieved. In case of poor-quality installation of glazing beads, the windows lose their sound and heat-insulating qualities, fog up, and lose their attractive appearance.

Glazing bead is an elongated wide or narrow strip made of expanded polyvinyl chloride (PVC) reinforced with a rubber gasket. More recently, glass composite beads have been used - a plastic material made of fiberglass and polyester resins as a binder. In terms of strength, such a material can be compared with steel.

Glazing beads differ in their shape:

Curly ones have a somewhat complex shape and are more expensive than ordinary square ones. They also differ in size. There are narrow and wide glazing beads. Wide ones are placed in windows with single-chamber packages, narrow ones in windows with three-chamber ones, reinforced glazing is suitable for a four-chamber window.

Repair of PVC, wood and aluminum windows and doors

In the field of repairing PVC and aluminum windows and doors, one often has to deal with the need to replace a double-glazed window or leveling a sagging sash using the so-called unpacking (Installing additional spacers in the sash). To perform this type of work, it is necessary to dismantle the glazing beads of the product. How to remove the glazing bead in the PVC window on your own and without consequences for the window, you will learn from this article on the repair of PVC products.

To perform this type of work, we need the following tools:

• Chisel (the wider the better) or specialized knife
• Plastic hammer without inertia

If we remove the glazing beads in the sash, then you must first close it. We begin to remove the glazing beads with the longest length, as a rule, in standard windows these are vertical glazing beads. In the center of the product between the glazing bead and the window profile, carefully insert the chisel, if necessary, helping by tapping the hammer on the chisel.

Master's advice

If you remove the glazing beads to adjust the sash, then you should start dismantling from the side of the handle.

When the glazing bead moves quite a bit from the window profile, it is necessary to tilt the chisel so that it is directed towards the removal of the glazing bead and, when the hammer hits, pushes the glazing farther from the product profile. When the glazing bead is far enough away from the window profile to be taken by hand, set the tool aside and gently pull the glazing bead while removing it by hand.

After removing the first glazing bead, there will be two shorter glazing beads next. (For standard windows, these are horizontal glazing beads: upper and lower.) Insert a chisel at the edge of the glazing bead from the side of the previously removed element and carefully working with a chisel and a hammer, move it away from the window profile. Now you can remove the last remaining glazing bead

It is very important to hold the glass unit or glass during the dismantling of the remaining glazing beads, in order to avoid the filling falling out and as a result of injury. Be extremely careful and careful!

After replacing the filling or performing adjustment work, the glazing beads must be returned to their place. Installation of glazing beads is carried out in the reverse order. We insert the edge of the glazing bead into the corresponding corner of the product so that the “mustache” of the glazing bead disappears into the corresponding groove in the profile and carefully hammer it in with a plastic hammer. Strikes on the glazing bead must be applied with emphasis and practically parallel to the plane to the glass unit. Do not overdo it with the force of the blow, because excessive zeal can lead to a crack and to the next replacement of the glass unit.

Master's advice

If you remove the glazing beads to adjust the sash, then often the glazing bead on the hinge side can be left as it is. it will not interfere with the installation of the linings and at the same time will keep the glass unit from falling out.

When installing the last glazing bead, insert the edges of the glazing bead into the corners of the product, slightly knocking it down with a hammer and trying as much as possible to move its edges to the edges of the already mounted glazing beads. When the corners are set, pressing the glazing bead to the glass unit, we begin to hammer in the glazing bead from the edges to the center until complete installation.

In aluminum windows, to dismantle the glazing beads, it is necessary to carefully remove the glass unit seal and by lightly pressing the glazing bead towards the glass, make it snap off from the product.

Selection criteria to be considered

Burglary resistance is of four classes:

1. The first is the simplest, most burglary, used for interior doors. It takes less than 5 minutes to open these.
2. The second one is opened within 5 to 15 minutes. They can be installed in internal and external doors.
3. The third one has increased protective qualities, and it will take more than 15 minutes to open them.
4. The fourth is the most reliable, they are opened in at least 30 minutes. Installed in doors for rooms that require increased protection.

The price for metal doors depends on the class of resistance to burglary, which implies the use of especially durable materials and devices with a high level of secrecy.

In addition to resilience, there is also secrecy. The number of possible combinations in it and the key can reach enormous values.

But it must be borne in mind that secrecy is a complex concept that includes:

There are three levels of secrecy:

Highest: In this case, the secrecy exceeds 100,000 possible combinations. There is protection against pick keys and mechanical stress. The key profiles and pin combinations are very complex.

The materials used to make the devices are acid resistant and the assembly is carried out with great precision.

Average. The number of possible combinations ranges from 5,000 to 5,000,000. Sometimes in designs there is no protection against the effects of picks and mechanical protection, but a complex combination of pins is necessarily used.

For manufacturing, durable and wear-resistant materials are used, with an average quality of parts.Usually, in such locks, the locking bolts of the mechanism are of high quality, and the body and handles are made of low-grade materials.

Low. The number of possible combinations ranges from 10 to 10,000.

The devices have no protective elements against mechanical stress. The location of the pins in the lock and the key profiles are fairly straightforward. Materials for manufacturing are not of high wear resistance and low strength, and the quality and workmanship are not very good, which is determined even by eye.

Reasons for replacing the lock

The most common cases for replacing locks in metal doors are:

Purchase of a new metal door. The lock is not included in the kit for the canvas, it is selected separately.

Loss of keys. This is the most common reason.

Even with a spare key, or making a duplicate, there is a risk of the original falling into untrustworthy hands. Poor quality parts, rough operation of the device can cause damage to the larva, lead to deformation of the crossbars. Using such locks is unsafe.

How the locks for metal doors of any type are changed correctly is shown in the video in this article.

Features of replacing glazing beads on an aluminum and wooden window

Removing the glazing bead from the aluminum window does not present any particular difficulties, the operations are carried out similarly to the above example - in the aluminum sashes, clamping strips are also used, inserted into the profile grooves.

Due to the lack of elasticity, aluminum profile beads have a slightly different design, their ends are cut at a right angle, and not at 45 degrees, as is the case with PVC products, so their removal is facilitated and does not present any particular difficulties.

When extracting aluminum glazing beads, proceed as follows:

• Pry the side bar with a spatula and remove it from the sash opening, do the same from the opposite one.
• Then they knock out the lower glazing bead, and holding the glass unit, take out the upper one.
• Upon completion of the dismantling of the clamping strips, remove the package from the sash and set it aside in a previously prepared place.

Wooden window profile

When dismantling glazing beads from frames made of wood, take into account their fastening to nails - this requires the application of great physical efforts and caution when bending them to avoid kinking. When carrying out work, a similar tool is used that is used when dismantling plastic strips, while taking into account the high probability of fracture of the wooden strip at the points of attachment with nails, therefore, the bending device should have as large an area of ​​contact with the glazing bead

A spatula with a width of at least 50 mm is best suited for these purposes; narrow chisels and slotted screwdrivers should be discarded. You will also have to make great efforts to push the spatula into the cracks, so you need a metal hammer to tamp it

When carrying out work, a similar tool is used that is used when dismantling plastic strips, while taking into account the high probability of fracture of the wooden strip at the points of attachment with nails, therefore, the folding device should have as large an area of ​​contact with the glazing bead. A spatula with a width of at least 50 mm is best suited for these purposes; narrow chisels and slotted screwdrivers should be discarded. You will also have to make great efforts to push the spatula into the cracks, so you will need a metal hammer to tamp it.

When removing a wooden glazing bead, proceed as follows:

• A narrow spatula is pushed into the slot in the middle of the right side bar so that its center is at the point where one of the hammered nails is located.
• By moving the spatula to the side, slightly bend the bar, then move the tool to other points to the locations of the fastening nails and perform a similar bending of the glazing bead.
• A wider tool (chisel, screwdriver) is inserted into the resulting narrow gap and the gap is carefully increased, after which the glazing bead is removed by hand.
• Since the second side glazing bead is rather difficult to remove without damage due to the rest against the ends of the others, it is easier to remove the lower and upper strips by prying them with a spatula in the corners, then gently bending them with a chisel and taking them out by hand.
• After removing 3 glazing beads, the removal of the last side glazing is not difficult, the only inconvenience in the need to maintain the glass unit is compensated for by simplicity and a decrease in the likelihood of breakage during its dismantling.

Dismantling of wooden glazing beads

What is glazing bead and why is it needed

A staple is a narrow strip usually made of a material corresponding to the profile (PVC plastic, wood, aluminum, fiberglass), which holds the glass or glass unit in the window frame (door) and gives it constructive completeness. The plastic glazing bead has a figured shape and, when installed, enters the grooves of the profile, where it is securely fixed with teeth due to the elasticity of the material; for a tighter fit, the bar is equipped with a welded or glued seal.

The outer surface of PVC glazing bead has a different shape and, depending on the design solution, can be round, rectangular, curly. Another feature of plastic glazing beads is a different width, which allows you to put double-glazed windows of any standard thickness into the window opening without changing the design or replacing the window sash.

In addition to hermetically holding the glass unit in the frame, the glazing bead prevents dust from entering the room, isolates it from street noise and reduces heat losses, acting as a kind of plug.

Replacing the front door lock cylinder (Kale): step by step instructions

Have you decided to replace the cylinder lock cylinder yourself? Use the instruction of the Torex professionals. It is designed for Kale locks, but in the same way it is possible to replace the larva of other similar models.

Repair and replacement of locks in metal entrance doors require attention and patience. Before disassembling the lock, read the information, watch the videos, check the availability of the necessary tools and, most importantly, take your time. Be prepared for the fact that the process can be delayed, since locks that are similar at first glance from different manufacturers have their own nuances.

Even in simple locks, replacing the front door cylinder can lead to undesirable consequences. For example, the lock can simply jam. If you have doubts about your own abilities, it is better to invite an experienced master.

If you are doing a self-replacement in order to save money, buy a new lock or spare parts from authorized retail outlets so that the mistakenly purchased item can be returned or exchanged.

Otherwise, replacing the larva in the front door lock at a cost may cost more than the services of a master.

Repair of locks of an entrance metal door

The reasons for the breakage of the lock of an entrance metal door are very different: urgent dismantling due to an accident, wear, improper operation, and others.

Depending on the type of breakdown, repair of the front door lock can be done by hand or call a specialist. Some manufacturers do not produce additional parts, and the elements of others may not fit in size and configuration. Then the only way out is to replace the whole mechanism.

How to insert into a wooden front door

If you have already inserted, or at least a handle with a latch in the interior door, then you will cope with this work.

You will need:

If you want to put a mortise in the front door, before buying it, measure the thickness of the leaf - it should fit in it, while not significantly weakening the structure.

So:

If your front door has a cylinder lock that you want to change for some reason, you don't have to completely change it. Replacing the front door lock cylinder can solve your problem, and this is less expensive and does not require experience and tools. You only need a Phillips screwdriver.

Locate the screw on the end plate that holds the cylinder in place and unscrew it.

Then insert the key into the lock and slightly turn it clockwise so that the flag goes into the larva's body and stops holding it in the lock. After that, it will easily fall out if you push it from the inside of the door.

After choosing a new larva of the same size in the store, install it in the lock in the reverse order.

Disassembly preparation and tools

Removing the glazing bead manually involves further removal of the glass unit from the window sash; before dismantling, the following preparatory operations are carried out:

• They free up free space in the room on the floor in a place where the location of the package will not create additional inconveniences.
• Lay cardboard, an old blanket or blanket on the floor in order to avoid damage to the floor covering by the sharp edges of the glass unit.
• If the glass unit is leaning against the wall to reduce the occupied space, additional material or cardboard is prepared to isolate its sharp edges from contact with the wall covering.

To remove the glazing bead from a plastic window, you will need the following household tools and protective equipment:

• Narrow spatula, wide chisel or slotted screwdriver, knife for bending the glazing bead away from the profile.
• A small rubber mallet for knocking out the trowel, strips and glass unit during installation.
• Be sure to rubberized gloves to protect your hands from the sharp, untreated edges of the bag.
• Roulette, if you plan to independently replace the package with an order from a manufacturer of a product of the same size.
• A pencil for numbering the removed glazing beads, in no case should you use a felt-tip pen that leaves hard-to-remove marks on the white PVC.

The main stages of extracting PVC glazing beads

Eliminating the problem with poor-quality door opening

To adjust the awnings, you need a hex wrench

If the entrance plastic door stops opening / closing as expected, it may have sagged and needs adjustment of the awnings. To adjust the awnings, we pry on, open the plug on the hinge, remove the decorative overlays, and adjust the awning with a hexagon.

If the sash creaks, grease the awnings with grease.

It is not possible to overtighten the screws due to the fact that their seats have expanded and the thread turns. We fix this problem:

• we change the bolts for longer and larger diameters (if necessary, it will be necessary to drill holes in the metal plate of the hinge);
• we seal the landing nests with wooden chips;
• we transfer the loops to another place, slightly shifting their location up or down.

The handle is loose, the locking mechanism is out of order

During operation, the screws with which the handle is attached may loosen. Repairing a loose plastic door mechanism is very easy to do with your own hands. At the base of the handle is a vertical decorative plate that covers the fasteners. We turn it to a horizontal position, pry the plate, pulling it slightly towards ourselves, turn the plate to a horizontal position. Access to the fasteners is open, we tighten the bolts with a Phillips screwdriver, return the cover to its place.

If the handle is broken, we purchase a new one from the window company.

The square rod for the hardware groove is standard for all handles, pay attention to the material from which it is made. We unscrew the broken product from the balcony door, insert the square into the hardware groove, bolt it

If the handle is intact, but it is difficult to turn, it is necessary to lubricate all moving parts of the fittings.

If the locking mechanism breaks down, you need to figure out whether it is possible to replace a separate element or whether the entire mechanism needs to be changed. For a more accurate determination of the degree of breakdown, we call the wizard from the window company.

Repair of the castle

Consider how to fix a broken lock on plastic doors with your own hands. We remove the door handle, using the above method, we get to the bolts, untwist them, take out the handle. The doorknob is inserted into the hardware groove using a square fixing. Watch the video below about repairing the castle:

Two types of locks are used on plastic entrance doors: with and without a latch.The latch keeps the door closed, preventing it from opening from the wind or touch.

Latches are:

• lanyard, triggered by pressing the handles;
• roller in the form of a hinge mechanism - to open the door, you need to pull it towards you.

Repair the latch, see this video:

Castles are:

• single-point - have one closing point, do not provide sufficient clamping of the sash to the frame;

• multi-point or transom - provide protection against burglary and more

  Multi-point locks provide high sound and thermal insulation

  tight fit of the sash to the frame.

Multi-point locks are more expensive, but they provide high sound insulation and thermal insulation due to the tight abutment of the sash and prevent it from sagging when closed due to locking elements located at several points.

The multi-point lock for plastic doors consists of a main and additional locking mechanism, a solid screw and a tire that moves all elements of the system. Such a lock can be with a folded push or roller latch.
