How to cut glass using a grinder

Crack in glass unit

Attention! If the window is under warranty and the glass unit has burst as a result of a microcrack, contact the company that installed it for you. As a rule, reputable suppliers replace double-glazed windows without any questions asked.

In other cases, there is no point in hoping for a free replacement. There are two options left:

or, after spending time, nerves and money, order a paid replacement of the double-glazed window;

or, having partially saved the above and gained useful experience, replace the glass of the double-glazed window with your own hands.

So, if you find a crack in a double-glazed window on the street side, and there is no time to repair it yet, do the following:

Using a chisel, remove the glazing beads, remove the glass unit, at the same time taking its dimensions (height and width), and insert it into the window so that the crack is on the side of the room. You can read more about how to install a double-glazed window and wedge the sash in the article “How to install a double-glazed window with your own hands.”

These simple manipulations, which may take a maximum of 30 minutes, will help protect the damaged double-glazed window from moisture and dust getting into the chamber (between the glasses), and will not add problems to you during subsequent repairs of the double-glazed window.

Features of the material

Not everyone knows what plexiglass is. How to cut it at home and what features does it have? First of all, plexiglass has the performance characteristics of durable plastic, and also looks like ordinary glass. This material is transparent. However, unlike glass, it does not break.

Thanks to these properties, plexiglass has become popular. How to cut it at home? In this case, not everything is so simple. The material itself is quite durable. Plexiglas is widely used. Indeed, in some cases, using ordinary glass is dangerous and problematic. The material can be processed using almost all available methods. However, there are some nuances that should be taken into account when working with plexiglass.

How to cut a double-glazed window without completely unsticking it. With my own hands.

How to disassemble a double-glazed window

Lay a thick cloth or thin blanket on the table (floor). Remove the glass unit and place it in the prepared area with the damaged side up.

In order to protect your hands, make a protection out of thick cardboard for the stationery knife.

In a factory-made double-glazed window, the glass is glued to the frame (primary sealing) using butyl sealant, which has high viscosity and adhesiveness. To make it easier to remove damaged glass, you can heat the perimeter of the glass unit with a hairdryer.

Having firmly fixed (placed emphasis) the glass unit, we insert the blade between the glass and the aluminum frame. Taking the handle of a stationery knife with both hands, carefully move it downwards with force. We carry out such actions on each side (along the perimeter) of the double-glazed window.

We separate the glass and clean the spacer frame from the remaining butyl sealant.

Carefully cut off the layer of sealant (secondary sealing) to the aluminum spacer frame.

If the glass is glued with double-sided tape, which indicates that the double-glazed window was not manufactured at the factory, the task of separating it is greatly simplified.

Now you can install the new glass. How to do this was described earlier in the articles “How to install stained glass in a double-glazed window with your own hands” and “How to make a double-glazed window with your own hands.” In them you can see in detail the options for assembling a double-glazed window using adhesive tape, butyl tape (recommended), regular aquarium and two-component polysulfide sealant “FENZI” (recommended).

Compliance with safety regulations

When cutting glass, it is very important to follow safety precautions, because the material is quite fragile and dangerous. You can not only cut yourself, but also injure your eyes from shrapnel.

Under no circumstances should you use a glass cutter to cut glass on your knees or on unreliable objects. Never grab the edge of the glass as the raw edges can be very sharp. If you want to lift the workpiece, you should grab it with your hands from the sides.

To avoid cuts, wear protective gloves and goggles before working. It is also important to wear closed shoes so that glass does not cut your foot if it accidentally falls. Clothing should be made of dense and thick fabric, which will also help avoid accidental injuries.

How to disassemble a double-glazed window

A double-glazed window is an integral part of any metal-plastic or plastic window. During operation, situations arise when it is necessary to disassemble the window in order to adjust mechanisms, repair or clean. Most people are faced with this task for the first time, so many questions arise about how to disassemble a double-glazed window. Disassembling a double-glazed window may seem difficult only at first glance, but if you follow the recommendations and follow certain rules, it will turn out that it is not at all difficult.

How to disassemble a plastic window

Before removing the glass unit from the window frame, it is necessary to disassemble the entire window. This event does not require any additional preparation; all you need is patience and a few tools:

• sharp knife;
• thick fabric gloves;
• flat and Phillips screwdrivers;
• an ordinary spatula with a width of at least 10 cm;
• if possible, rubber suction cups for transporting glass;

Disassembly should begin with the window sashes. The rod that holds the window sash is removed from the top hinge. While leaning out, you must hold the window so that it does not fall down. It is worth paying attention to the fact that the entire sash has quite a lot of weight, so work must be carried out with extreme caution. The removed element is lowered to the floor and carefully, in a vertical position, leans against the wall.

The next stage of disassembly is dismantling the fittings. The window handle is removed by unscrewing 2 screws, which are hidden under the plastic casing. The locking device can be removed using a shaped screwdriver. All removed parts must be placed in a separate place so as not to lose a single bolt, since it is quite difficult to find a replacement for it.

The beads are detached from the sash by prying them off with a sharp knife, spatula or chisel, but in no case with a flat screwdriver. Plastic is a very soft material, and the thickness of the screwdriver will not allow you to perform this procedure, since this must be done carefully. By inserting a spatula between the profile and the bead, you need to lift it a little at a time and move it to the side where it has not yet opened. If you lift one part and pull it out with your hands, you can break the bead itself. The process of removing the bead begins with the longest one.

How to disassemble the glass unit of a plastic window

It is recommended to disassemble the glass unit in cases where it is very necessary. After removing all the beads, you can easily remove the glass unit. If there are rubber suction cups, you can place the sash on the floor and remove the glass while holding the frame. Without rubber suction cups, the process may take longer, as it is a little more difficult to do, but it is quite doable. The principle of dismantling is the same as with suction cups. Only in this case you need to be very careful not to drop the glass unit.

One Reply to “Cutting glass tubes”

Will the paper not catch fire when we hold a small, uncovered strip under the fire?

To cut a glass tube of small diameter, it is placed on the edge of the table on some soft and even lining - a piece of cardboard or a notepad (Fig. 58, a) and a scratch is made across it with the sharp edge of a small triangular file. This scratch should be a continuous line and located approximately one-sixth of the circumference of the cross-section of the tube. Then the tube is taken with both hands, scratching away from you, so that the thumbs rest against the tube on either side of the noticed break. Slightly stretching the tube to the sides, quickly break it, for which the right side of the tube is turned clockwise, and the left side counterclockwise.

In the absence of a file, the glass tube can be cut in another, very common way. To do this, wrap the tube with two wide strips of moistened paper so that there is a narrow gap between them in the place where it is planned to cut the tube. The glass in this gap is heated over an alcohol lamp or gas burner, while rotating the tube so that the glass is well heated on all sides. Then a drop of cold water is allowed into the gap, and the tube is divided into two parts.

The sharp edges of the tube are sanded with a file or emery cloth. You can lightly melt them in the flame of an alcohol lamp or gas burner.

A plastic window was broken: what to do?

At first glance, it may seem that the plastic window is very strong and difficult to break. In fact, this is not true. Owners of metal-plastic structures quite often face the problem of broken double-glazed windows. And if with ordinary glass everything is very clear, a replacement is needed, then what to do with a broken plastic window? This is exactly what we want to talk to you about. If you don’t have time for all this, and you want to quickly solve the problem that has arisen, then order the repair of plastic windows in Moscow from the Teplo Doma company.

In general, yes. There is a double glazed window with one broken glass. I want to disassemble and glue the aquarium. use as a greenhouse. Very convenient, by the way! I have already glued 4 such aquariums, but the size is smaller, about 30 by 40 by 20. The requirements for tightness are minimal. In general, cheap and cheerful. So, how to disassemble this double-glazed window so as not to damage the entire glass? The rubber around the perimeter has already been cut out, but there’s something he’s not going to look into further. but I'm afraid to pick. Respected men, especially. those who deal with plastic windows, give good advice to a lady who is obsessed with creating additional problems for herself. I should add. VEKA windows

Is it possible to repair a broken plastic window?

So, this has already happened through your fault or not. What's next? Is it possible to repair damaged glass? In theory, repairs are, of course, possible in some cases, but doing so is not entirely advisable.

If the glass in a plastic window is broken, some recommend sealing it. I would like to immediately note that, in principle, this can be done, but keep in mind that the window will no longer perform the functions assigned to it

. A sealed double-glazed window will not retain heat; it will constantly fog up from the inside, allow moisture to pass through, and dust and dirt will get inside. This happens because the seal is broken.

The factory uses special technologies when producing double-glazed windows. The glasses are connected to each other through spacer frames, which are filled with special granules. These same granules absorb residual moisture inside the glass unit.

There is a general misconception that there is a vacuum inside the glass unit. Of course this is not true. Yes, the double-glazed window is sealed, but there is no vacuum there. In fact, this is impossible, since when you try to do this, the glass will be deformed, the spacer will move, and the seal will be broken.

But what then is the glass unit filled with?

? Ordinary air or inert gas with low thermal conductivity. As a rule, argon plays its role. If a plastic window is broken, the tightness of the glass unit will inevitably be broken, all the gas will escape, or the air inside will gain moisture.

Let's return to the subtitle question - “Is it possible to repair a broken double-glazed window?” Only in factory conditions. But this is not profitable, so the answer is no!

Plexiglas: how to cut?

In some cases, the use of a saw is allowed. It can be tape or disk. The latest type of saw is designed for straight cuts. In this case, the seam is neat and clear. As for the band saw, it is suitable for making workpieces. It is unlikely that it will be possible to cut clear edges with such a tool. To make the surface smoother, it is recommended to use a milling cutter.

It is worth noting that this method of cutting plexiglass can be used not only in production, but also at home.

What to do if a plastic window is broken?

If it is not possible to repair a double-glazed window, then what should you do? It needs to be replaced. Replacing a broken plastic window

– is far from the easiest event. That is why the Teplo Doma company offers the help of its specialists. Experienced craftsmen will quickly select what you need and replace the broken glass in the shortest possible time.

You can discuss all the nuances right now in an online chat. The specialist is waiting for you.

If there is no desire to turn to professionals, then replacing a broken double-glazed window in a plastic window is done with your own efforts.

Conventionally, this event can be divided into three stages:

• Taking measurements.
• Removing old glass.
• Installation of a new double-glazed window.

I would like to talk about each stage separately.

Taking measurements

Replacing broken glass in a plastic window begins with taking measurements. You need to find out what size the old double-glazed window was. But how to measure it if it is completely broken? Some owners of plastic windows are confident that in order to take measurements, it is necessary to remove the double-glazed window from the sash. But it is not so. Everything can be done on site. To do this, you need to measure the distance between the boundaries of the beads, and then subtract 1.5 centimeters from the resulting number.

This way you can find out the dimensions of the old double-glazed window and therefore order a new one. There's just one problem. If you make a mistake in your calculations, the double-glazed window simply won’t fit.

. This will be truly offensive.

That is why we recommend seeking help from the specialists of the Teplo Doma company. When performing any work, they take full responsibility for the quality of their performance. Why will you worry once again that you made a mistake somewhere and in something? Shift this burden to those who are ready to bear it, and do things that are more pleasant for you.

Removing old double glazing

If a plastic window is broken, you know what to do: first take measurements, then dismantle the metal-plastic structure. Removing an old window will require certain skills. Now we will discuss everything you need to know for this.

To remove a double-glazed window from the sash, you must first remove the glazing beads. You should start with the longest ones. The fact is that it is much easier to remove them. Then, you should do the short ones.

The glazing bead is removed using a special plastic spatula. Some people do this with a chisel, but in this way, due to inexperience, you can damage the surface of the window frame. The spatula should be inserted between the bead and the sash. Then use a rubber mallet to apply several light blows to the shoulder blade. It is necessary that there is a gap between the bead and the frame. Then the bead should be removed.

Important!

The hardest part is to pull out the first bead. Once this is done, they will no longer be a common structure.

Cutting plexiglass with a cutter

Methods for cutting plexiglass at home can be completely different. Some people use a hacksaw, and others use a cutter. Essentially, this tool is a saw with just one tooth. To cut plexiglass, you will need a metal ruler of a certain length. This tool must be placed on the sheet of material in the place where it needs to be divided. After this, you need to run the cutter along the ruler.

When the cut reaches ½ of the thickness of the sheet, you can stop and then carefully break the material. If defects appear, they can be smoothed out. To do this, you need to sand the edge of the plexiglass with sandpaper. If desired, you can make your own cutter from emery cloth. Some experienced craftsmen use pieces of glass to cut plexiglass. This method requires reliable hand protection.

What can be done with glass from a double glazing unit?

My glass cracked in a plastic double-glazed window. They replaced it under warranty, but they didn't remove the old glass.

Those. Of the three glasses, only one is cracked, the other two are intact. The glass is large, it would be a shame to just throw it away.

What can you do with them?

It seems that the glass in double-glazed windows should not be ordinary, as before, but either tempered or coated with something for strength?

What will you do with him? It’s unlikely to cut, it seems to me that they should be stronger than ordinary glass. Make a mini-greenhouse with a recess in the country, cover it with these glasses.

Paint, cover the edges with slats, and make a beautiful partition in the room.

But I wouldn’t use it at home, in case it breaks into pieces. Fuck it. As a child, I severely cut my hand on the glass in the door. Very unpleasant memories.

So I wouldn’t be greedy and throw it away.

Thank you for your opinion!

Maybe someone has already done something like this. I would like to see/hear real experience. Did it work or not?

Maybe someone will write. For example, when we do repairs, they put out old doors with glass to garbage containers, there are guys there and they take away all the glass. but they hardly go online

something like the original fire starter

glass on top, lighting on the bottom inside the table

half glass greenhouses made from old glass

I didn’t find a greenhouse with a hole in the ground, but the principle is approximately the same. A hole is dug. Cover it with compost and soil 1/3-2/3, make a side, and cover it with glass.

The whole trick is that cracked glass is usually cut for renovation and the break is removed, but I don’t know if it’s possible to cut glass from a double-glazed unit at home, maybe someone will write. But using a cracked one is dangerous.

When I was a child, my grandfather and I made greenhouses from old, ordinary glass. No photos. Our own glass is old, ordinary, just lying there, waiting for spring, it will be a greenhouse. That's why I got into your thread

Tool selection

Cutting glass yourself is suitable for those who cannot install good plastic windows for financial reasons, but do not want to install cheap analogues, since they do not provide such reliable heat and sound insulation. Proper restoration of wooden window frames and insertion of new glass, observing all technological rules, will increase the service life of familiar old structures. The easiest option for replacing glass would be to contact a specialist, however, you can cut the material with the required parameters yourself.

The rule “measure twice and cut once” is directly related to such an activity as cutting glass with your own hands.

The first step is to measure the necessary parameters for insertion. It is necessary to immediately make precise marks on the glass, since repeated cutting of the material to reduce the size increases the risk of cracks and chips. An important parameter is the deviation of the glass dimensions from the dimensions of the place where it will be inserted.

We cut the glass with our own hands according to the instructions in the photo.

It is always necessary to reduce cutting measurements by 1-2 millimeters, since wood can increase or decrease in size under the influence of weather conditions. If the glass is precisely adjusted to the parameters of the frame, cracks may occur across the entire surface of the updated window. As a rule, this happens with the onset of cold or hot days and simultaneous high humidity. In addition, some reserve will protect you from uneven cuts and the inability to accurately insert glass the first time.

When sold, finished glass sheets have a large weight and size, so you need to think about their transportation in advance. It is necessary to have a cargo transport and at least one assistant who can assist in the loading and delivery of glass to the place of further cutting. When carrying, be sure to have gloves to keep your hands safe.

In the place where the glass will be cut, you need a large table with a smooth surface, free of debris and obstructions. If these conditions are not met, there is a risk of glass cracking in the wrong place where the cut occurs. The cutting tool can only be sharp, preferably a new glass cutter. When using old equipment, the process may take a very long time or may not work at all.

We also recommend watching a video on how to cut glass correctly.

Is it worth replacing broken glass in a double glazing unit?

Replacing broken glass in a double-glazed window is a labor-intensive process, and such a procedure is not undertaken very often. Experts believe that in most cases it is more rational to install a new double-glazed window to replace the damaged product. However, there are situations when it is more profitable to replace the glass. To determine which method is better, you need to correctly estimate the cost of the upcoming work. This can only be done by a specialist, who must be invited immediately after the window is damaged. Under no circumstances should you try to fix the problem yourself, as such actions will only make the situation worse.

Laser cutting of plexiglass

How are plexiglass products made in production? Typically, a laser is used to cut this material. This is the most convenient method. However, it is simply impossible to use it at home. Thanks to the thin laser, a precise cut can be made. Even small parts of future products are usually cut out in this way. However, this cutting method has certain limitations: the laser beam creates high stress on the material. In the future, it is simply impossible to glue individual parts together.

How to cut a double-glazed window without completely unsticking it. With my own hands.

It is possible to cut products from plexiglass only in industrial conditions. If necessary, you should contact the appropriate organization for assistance. Main. make all the drawings in advance. It is also worth choosing an experienced master.

In what cases is it advisable to change the glass in a double-glazed window?

If we are talking about a standard single-chamber model made of ordinary float glass, then it is better to immediately replace the entire product, since repairs in this case are not economically justified. However, windows are increasingly equipped with multi-chamber double-glazed windows, which are made using expensive materials. In this case, repairing a double-glazed window is beneficial and an appropriate measure. Glass replacement is recommended in the following situations:

• in two- and three-chamber double-glazed windows;
• if triplex or other expensive type of glass was used in the manufacture of the model.

However, even in such situations, repair is only possible if the technician confirms that all other components of the expensive structure have not received damage. Otherwise, the event loses all meaning, and it is much more practical to order the installation of a new double-glazed window.

Preparatory stage

Of course, before removing a window module from an existing opening, a series of preparatory works should be carried out, namely:

1. Make sure that the climatic characteristics comply. After all, if you agree to carry out construction operations at sub-zero temperatures or excessive humidity, it is much more difficult.
2. Prepare the work site (clear the opening area of ​​foreign elements);
3. Stock up on necessary construction equipment. A set of carpentry tools, a mounting knife, a hammer drill, a chisel and a hammer - this is perhaps the most complete list of all the necessary equipment.

Glass replacement process

Window owners immediately need to understand that it is impossible to accomplish this task on their own. That is, it is theoretically possible to make a replacement, but to ensure the required level of quality is not. The technology for manufacturing double-glazed windows is described in detail in a special review on OknaTrade. After reading this material, it will become clear why it is impossible to ensure a high class of tightness at home. If it happens that a double-glazed window is broken, glass replacement should be carried out in a specially equipped workshop for their manufacture and repair of such products. This procedure looks like this:

1. The master removes the clamping beads and carefully removes the glass unit from the light opening.
2. Then the product is transported to the workshop on special transport.
3. In the workshop, the first step is to dismantle the damaged glass, which is cut off from the spacer frame using a sharp spatula or knife.
4. After completing the previous stage, the old sealant is removed from the glass unit and spacer frame. This is done using a knife, chisel and white spirit.
5. New glass is measured, cut, washed using a special technology and prepared for installation.

• The remaining structure is checked for integrity, correct shape geometry and tightness of the remaining silicone connections. It may happen that you will have to disassemble the remains of the glass unit.
• If everything is fine with the undamaged part of the glass unit, then the prepared glass is attached to the spacer frame, after which the structure is placed in a special press.
• After the initial sealing, the junction of the new glass with the spacer frame is checked for the absence of white spots - their presence indicates poor quality of the material used or a violation of the technology.
• The final stage is the application of sealant around the perimeter of the glass unit, which is carried out at strictly defined temperature and humidity.
• The repaired double-glazed window is transported to the site and installed by a specialist in the light opening. The window is adjusted if necessary and checked for leaks.

Don't forget also

To install the finished glass into the frame, it is necessary to clean it from the old surface and traces of glass fastening (window putty or silicone sealant). Everything is cleaned with a spatula or knife. If necessary, rough spots can be sanded down after final cleaning with fine-grit sandpaper. Then you need to prime and apply a thin layer of drying oil around the entire perimeter inside the frame.

After both layers have completely dried, softened window putty is applied using the same spatula or knife. The layer must be continuous and even, no more than 5 mm thick. If sealant is applied, it should be applied in a continuous and not too thick line to avoid a lot of excess. You need to let the sealant dry slightly. This way it’s better to grip the glass with the wood.

Finally, the glass is inserted into the frame. It is necessary to press lightly on it, seating it in the frame, in order to displace any excess window putty or sealant that has formed. After the glass has set to the wood, you need to remove the dried excess and secure the glass in the frame using special nails or pins.

You can secure them with triangular plates, placing the plates on the same nails. After this, rollers are rolled out of window putty and placed at the junction of the glass with the frame and smoothed until all nails or other fasteners are completely covered. But the window will look much more aesthetically pleasing if the glass is secured with glazing beads, which are nailed to the frame at a distance of at least 5 millimeters from the glass.
