How to cut a sandwich panel. Variants of window slopes

The traditional method of finishing is of course plaster. If such work is performed by a qualified specialist, then for many years you can forget about the repair of slopes. An important point when choosing this method is the lack of the need to install a plastic corner at the border of the slopes and walls.

The choice of such a method is justified in the first place if the wall in which the window is located is also leveled by plaster. But, given that when the slopes are removed, the plaster layer reaches 5-7 cm. and more, it is necessary to install a reinforcing grid. Only a master can do qualitatively such work.

I was not satisfied with this option because the wall is a framing window, it was made of drywall, and in addition, a countertop was already installed, which played the role of the windowsill.

As an alternative, three options were considered. Finishing the slopes of the window using drywall, followed by painting, slopes of drywall with plastic plastic and the use of sandwich panels on its surface.

Now the option with painting slopes from drywall is used only with budget repair of non.residential premises. Plastic glued on the basis of drywall. a variety of the same economical option.

Temperature changes, as well as high humidity, quickly destroy drywall. Perform restoration repair every 2-3 years-not our method. Therefore, we opted for PVC sandwich panels.

Sandwich panel is 10 mm. The sandwich consisting of two PVC sheets between which is located a heater made of polystyrene foam. The only inconvenience when buying is the need to acquire a whole sheet of 3000×1500 mm.

There are no difficulties in working with him. it is easily cut by corner grinding and even an ordinary knife (if necessary, grossly cut into pieces for climbing the apartment).

Installation of sandwich panels. Installation of sandwich panels: step-by-step instructions

The sandwich panels were invented in the 30s of the last century, but are still highly popular in housing and industrial construction around the world. This is a practical, inexpensive and durable material that combines the quality of the insulation, noise and waterproofing, as well as exterior decoration. In this article we will talk about the varieties of sandwich panels and installation methods.

Characteristics of sandwich panels

Sandwich panels are made in specially equipped factories in an exclusively mechanized way. They consist of several layers, representing a kind of “sandwich” or “sandwich” (hence the name) from various building materials.

A thermal insulation material of various quality is placed between the metal sheets. The thickness of the sandwich panels depends on the insulation, it also determines the cost of the product. This parameter is also affected by the thickness of the metal shell.

For the construction of the roof, thin panels with sheets of 0.6 mm are usually used, and more massive are used for wall cladding. with a sheet thickness of up to 1.2 mm.

The sizes of sandwich panels also affect pricing. The standard product reaches 12 m long, but at the request of the customer this parameter may change.

The total thickness, taking into account metal sheets and insulation, can be 40-250 mm. The width of the panels depends on the profile and is from 50 to 120 cm.

Narrow products are mainly used for the construction of garage gates, and wide. for the construction or decoration of all kinds of objects (warehouses, houses, garages, etc.D.).

The most expensive. three.layer sandwich panels. This is due to a more complex structure, high strength and better characteristics.

Advantages and disadvantages

Such many years of popularity of sandwich panels is explained by a mass of advantages and advantages in relation to other materials.

  • Fast installation. the construction of walls or cladding with panels does not take much time;
  • The small weight of the products. a relatively light design does not require financial costs for the construction of a durable foundation that would be needed, for example, for a brick or concrete box;
  • Structures from panels can be upgraded over time, disassembled and transported to another place;
  • Savings. to build a house from sandwich panels is several times cheaper than from brick or blocks;
  • Fire safety. the thermal insulation layer is reliably protected from exposure to direct flame with metal sheets. The exception is a sandwich panel with PVC, polyurethane foam or polystyrene foam in the middle, so carefully study the composition;
  • Environmental friendliness. in production, materials safe for health and nature are used;
  • High strength. wall sandwich panels are made of thick metal sheets resistant to mechanical damage;
  • Thermal insulation. this parameter depends on the thickness of the insulation in the “sandwich”;
  • noise insulation. the thicker the panel, the better it protects against extraneous sounds;
  • You can mount a sandwich panel at any time of the year, except winter with fierce frosts (icing may appear at the joints).

Slopes from sandwich panels. Facing window slopes with sandwich panels

Sandwich-panels decoration of window slopes.

Different finishes are used to facing the window opening inside the house. Not so long ago, the choice of finishing materials was limited to plaster and drywall. Today, sloping panels are considered one of the most common decoration options.

Why are slopes needed

The finished window slopes hide the mounting seams and give accuracy to the appearance of the window and the completeness of the aesthetics of the interior

Advantages of sandvich finish with panels over other types

Before possible types of slopes of slopes, the sandwich panels have the following advantages:

  • ensuring the optimal insulation of the cold walls of the opening from the microclimate in the room, which is impossible to achieve if you make a window soda from GKL;
  • a decrease in the noise level in the room, when plastering slopes, is not about any insulation of heat and noise;
  • improvement of illumination thanks to the reflective surfaces;
  • the low weight of the finishing material is less than 2 kg/m2 versus 10 kg/m2 of gypsum plasters with the same thickness;
  • the possibility of a solid connection to the PVC frame, which cannot be achieved by plaster slopes;
  • Inappropriateness of temperature changes and direct sunlight, so such slopes are suitable not only for windows, but also for doors;
  • the impossibility of cracking, while cracking of a plastered window slope is not uncommon;
  • the lack of the need for surface processing with putty, unlike gypsum cardboard finishes (there are no wet finishing work);
  • carrying out installation work with a minimum amount of construction waste, which cannot be imagined when using GCL or plaster;
  • the ability to use detergents to remove pollution, which simplifies the care of the sloping surface.

How to cut plastic panels. How to cut PVC panels

This operation can be performed by many tools, however, the most common solution is various types of hacksaws: on wood, metal. We recommend paying attention to the hacksaw of the vira brand. They are ideal in price/quality ratio. The most popular because it significantly saves time if necessary to prepare several panels of the same size, you can saw several pieces at once. The cut is carried out strictly with the front side of the panel upward, slightly holding it under the slope. It is recommended to squeeze the panel for stability, but in no case should you strongly compress it.

In the case of a hacksaw on wood, it is recommended to use the teeth of the transverse or mixed sawing. The thing is that they leave a very even, without a zabrin section, after which additional processing of the sawn surface is most often not required.

However, how to cut off the PVC panel if there is no hacksaw? It is quite possible to use an electric jigsaw. However, in this case, it is worthwhile to carefully monitor the pressure of pressure so as not to break the panel.

And if there is nothing at all at hand, and you need to do work right now than cut off the plastic panel? You can use a knife, it is desirable that it be a special construction knife, but for lack of one, a very sharp household, hunting knife is suitable. An ordinary stationery knife is also good, but it is necessary to cut it very carefully, since it is quite fragile and sharp. In this case, it is necessary to mark the fishing line for the trimmer on the panel, according to which it is supposed to make a section. Then, along the ruler (if the fishing line for the trimmer should be straight), a deep incision is made by the clerical knife strictly along the line, after which the panel breaks. If the fishing line for a trimmer should be with bends, it is impossible to break in any case, since the panel will simply break, the material will be spoiled.

How do professionals cut wall panels? There is no definite answer, since, depending on the type of plastic and the panel, upcoming work, one or another tool is selected. For example, it is easiest to cut it in a straight line with a hacksaw, but it is better to cut the bends with an electric jigsaw, or if it is not, with a construction knife.

What is the difficulty?

The sandwich panels consist of several layers: external (in most cases-metal), which provide strength and internal, which is responsible for insulation. It is the latter that limits the capabilities of cutting. Since most heaters are easily ignited (or caustic smoke is distinguished during flowering), use fire and other cutting methods that heat the surface to temperatures above 200 degrees is strictly prohibited. The heating is also undesirable for the polymer coating of the outer layers: when heated, it loses integrity.

Before installing plastic slopes with your own hands, you need to familiarize yourself with the qualities of the material that is used for their manufacture. One of them can be a PVC panel.

Description of the material

Another name of this material is ceiling panels. They make them from polyvinyl chloride.

They consist of two plastic plates with stiffeners inside. For some models, the presence of locking joints on the ends is provided.

The panels can have different sizes, but when installing them will still have to be cut in accordance with the necessary sizes. Despite the fact that the panels can have a length of 3 and 6 meters, 6-meter products should be purchased. The thickness of the panels varies from 0.5 to 1.2 cm. The type of product can also be different: panels, rails or PVC sheets.

How to cut?

Obviously, due to constructive restrictions for cutting, only simple mechanical methods remain.

Sheets with an outer layer of polymers (plastisol, polydictoriona, polyester, pool) are recommended to be cut with an electrician, corner grinder or a construction knife. Operations begin with preliminary marking and cutting of the outer layers. The internal is cut off last. Synthetic surfaces are very durable and therefore their cutting is a fairly troublesome thing.

OSP or drywall are easier to cut. A strip or disk saw is best suited here. They can also cut metal coatings. An even better option for metal is a press gill. Its mechanism will make an incision quickly and exactly vertically.

Economical cutting of SIP panels. How and how to cut sandwich panels

Specific example. Such a panel had to be done:

a) from a standard SIP panel size of 2800x1250mm (a shackled part goes to waste):

b) from a standard panel size 2500x1250mm:

As they say. feel the difference. And everything is only because of a small, not meaningful triangle that lies during installation on the upper board of the strapping:

Similar points must be taken into account at the stage of design and preparation of work drawings.

One more example. It was necessary to make such panels:

It would seem easier to cut the sandwich panels like this (the shaded part is in waste):

And here is a more economical cutting SIP panels of a standard size 2500x625mm:

Now let’s talk about how and how to cut sandwich panels

Cutting the skin of sandwich panels from OSB-3 is quite easy, and you can saw it with anything: from circular saw and electrolobesis-to hand hacksaw. We do not recommend only using a chain saw, since the drink will turn out to be rough and with large errors. But in “field” conditions without using stationary equipment, cut a sandwich panel with a thickness of 174-224mm into one technique-a problem.

So, we act as follows: we saw the casing in turn from one side and the other, and then we cross the panel at the site of the cut. It is even better not to break the polystyrene foam, but to stretch through the cut, with sawing movements, the steel wire-then the cut of the SIP panels in the site of the saw is almost perfect.

The second question is how to make a mounting groove in a SIP panel

In the manufacture of a set of a house in the factory, to sample a groove for a key, as a rule, special machines are used. One of the examples of such equipment is presented on the website https: //

To select a groove in construction conditions, for example, when building a house from a SIP panel with your own hands, it is convenient to use a thermal, which is an electric heating element of a special shape (photo on the left).

If for some reason it is not possible to acquire factory manufacturing thermal, then it is easy to make a thermal cutter for sample the groove yourself (the photo on the right shows how it works).

For the manufacture of the simplest thermal cutter, a small piece of nichrome wire with a diameter of the order of 0 is required.8mm and a car charger with the possibility of manual current control.

Of course, it is not as convenient to work with such a thermal cutter as a factory thermal, since before the sample of polystyrene foam you have to make slots along it along the edges of the sheathing, for example, a corner grinder, or a chain saw. But when you have to cut a sandwich panel in the “field” conditions, it will come down.

This time we will analyze in order how to make slopes on the windows from the sandwich panels with our own hands. This method is the most simple in terms of installation as a whole and is perfect for the cosmetic repair process, there will be no dust as, for example, installation from drywall on metal profiles, and even more so if you are aligned with mixtures and later paint.

If desired, you can use the assembly scheme with profiles and insulation by analogy with an example of slopes from drywall.

Preparation for work

If the window is new, then it is necessary to tear off the entire protective film from its frame, as well as the film on both sides of the plastic windowsill. Cut off with a knife with interchangeable blades sticking out an mounting foam behind under the face with a frame (of course, if it interferes).

Now a list of tools and material for installation;

  • Electric screwdriver with a cross.bit
  • Mounting foam with a gun for it
  • Corner grinder with metal disk (this tool is most easier to cut a sandwich panel), or an ordinary hacksaw with small teeth
  • Direct levels on 2m. and 1.5m. Construction
  • Roulette, pencil simple, square
  • Sandwich panels
  • Starting guide plastic under the thickness of the panel
  • The corners are plastic external finish, you can glue the F-shaped corners if you already have wallpaper
  • Scotch tape
  • Self.tapping screws for guides
  • Glue liquid nails for a gun specifically designed for this format.

Before applying foam, do not forget to intensively shake the balloon for a few seconds. Otherwise, too liquid foam at the output will expand greatly and it will become extremely difficult to control the process!

DIY slopes assembly

Should start with starting plastic guides. They must be screwed around the entire perimeter of the window frame with self.tapping screws using an electric screwdriver, do not even try a screwdriver nothing to work out. We fasten in order on the upper edge, and then on the left and right of the windows.

Next, measure and transfer the size of the upper slope to the leaf of the sandwich panel and cut along the drawn lines of the corner grinder or hacksaw. Raise the workpiece to the top and inserts into the P-shaped screw. Sometimes this business comes in, help with a fingernail or stuff something thin between the plastic (for example a square).

The outer edge of the panel should be fixed with masking tape by leaving the gap under the mounting foam. Glue the adhesive tape simultaneously applying the right level on the outer corner, thereby controlling the perfect straight line for the trimmer. For the best effect, I sometimes also use spacers from improvised means, in the photo you can observe such, I made them from ordinary substrate for the laminate (even twisted paper torn).

It happens when the gap under the foam is too wide because of the large reversal of the slope, and the panel can squeeze out the strong pressure of the foam. So that this does not happen, I just shot a long construction rule on both edges of the window (in the rule at both ends it is necessary to drill holes), such a move allowed to restrain the installation pressure, only the workpiece should be drunk in advance by 2 cm. wider and then cut off the excess with a knife. By the way, before taking off the rule, draw a strip under the cut with a knife with a pencil.

We proceed to the assembly of the side sides. We fasten the starting starting, but now from below directly to the plastic windowsill and from above to the width of the opening panel. Next we cut out the blanks, insert the places into the piles and repeat all the work described above with painting tape and a gun for foam.

A small note. So that the installation does not pile myself too aggressively, I just fill the gap with foam not all at once, but in places with a 10cm pass., after 30 minutes I put the level and check for everything in order. There was a problem, just slightly press on the corner with your palm, remember that the material can be easily served and it will not be beautiful.

The last one remains, we remove the frozen foam and glue the plastic corners, provided that the wallpaper on the walls, and so with this work, it is worth it to postpone it for later. Read about the installation of corners here. Everything is in detail there and is clear.

I look forward to questions in the Комментарии и мнения владельцев under the article, do not hesitate and ask!

How to cut windows for windows. Finishing with plastic materials

However, at the moment, the most progressive material decoration is plastic. And this is fully justified: an attractive appearance, the possibility of quick installation, and most importantly the operation of the window and the slope are almost equalized. At the same time, performing plastic slopes with your own hands is much easier than plastering or exposed from GKL, and they do not need to upgrade coloring.

PVC panel

It is not recommended to use external windows for slopes of external windows, but for any room windows, a decorative and budget option is possible-slopes of windows from PVC panels. However, the panels require a thorough selection. the sample must be inspected “to the light” whether the structure of the internal ribs of hardness is manifested on the front side. And so that it does not sell when cutting across, cutting the panel with a knife is better from the wrong side.

Sandwich Panel

But the so-called “sandwich panels” are most popular for the manufacture of slopes, they are structurally made with a heat insulator, therefore, they are recommended for the installation of slopes of any windows and are an indisputable leader. Examples where slopes of plastic and windows decorated with a sandwich panel are the absolute majority. PVC and sandwich panels are very similar technologies. Therefore, consider everything at once for both materials.

As already mentioned, the marking is almost the same for any type of slopes, but further installation is possible in two ways:

    The sides of the slope are tucked for the window block. It is done when the layer of foam allows, and the window opening is wide enough to organize a turn. For all its attractiveness, the method has a disadvantage, you have to cut a little foam under the panel. For a wide block, this is uncritical, but with 50 mm you need to be careful.

The method with the starting profile involves additional materials and “unnecessary body movements”, but it is it is the most simple and accessible for repeating people without experience. The thing is that the sides of the slopes are reliably held by the profile during the work. Then this type of installation will be disassembled:

    Cut the starting profile with self.tapping screws, focusing on the edge of the window unit.

It is recommended to score the back of the back with sandpaper, but this is not critical, after moisturizing the surfaces of the foam and so it is normally glued. We insert the panel into the profile, additionally darken near the window. On horizontal marking on the wall, we align it and fasten the wall to the top with painting tape, controlling the straightforwardness.

We will immediately install both sides in place and also dump near the window and be liberated with tape, controlling the vertical.

Disk saws for sandwich panels

Having accumulated a sufficient amount of funds, you decide to make, for example, a garage. After buying the necessary materials, frame, panels, fasteners, cement and the rest, the moment of preliminary work comes. The finished foundation has survived the moment the frame installation is now time to start installation. However, here’s the bad luck, a small error in measurements or the mistake of the manufacturer and there is an ignorance, the panels do not fit! Here we will find out how to cut a sandwich

Cutting hinders

Sandwich panels are a multi.layer design for surface decoration. From iron sandwich panels there is an option to build persistent structures, since the material is able to make a sufficiently higher load. That’s why he gained extraordinary popularity in the construction sector. It is not difficult that due to the number of layers, certain obstacles appear.

Wall sandwich panels and some features of their installation

To make it easier to understand the technology of installation of wall panels, we suggest you familiarize yourself with instructions and photom meters.

And now, having dealt with a explanation of the order of action, it is worth noting the nuances inherent in each of the stages of installation

Features of raising sandwich panels using a crane

The main task with the clamp of the panels with clamps with eyelets is not to pull the screws, and, at the same time, do not leave them weak. In the first case, the metal will be predicted, which will lead to a violation of the tightness of the joints of the facial layers. This means that water will seep inside, impregnating the insulation and destroying it. In the second case, with a puff too weak, the panel can simply slip off when lifting, which is very dangerous not only for health, but also for life.

Longitudinal joints should be perfectly fitted. As for transverse seams, a small discrepancy is allowed here, which will subsequently be closed with inputs (style elements).

Sandwich panels are quite diverse

Fastening sandwich panels to the frame

When fixing elements, the screws should not be pulled. This will lead to dents, which means that the inhibits simply will not be able to close the cracks tightly.

Cons and pluses of slopes from sandwich panels

The main advantages and disadvantages

The specified type of slopes is performed using mounting foam. high.quality sealant on a polyurethane basis. The material is distributed in the center between two small sheets from the PVC structure.

Among its main advantages, the following are distinguished:

  • No additional processing and decoration of the surface after installing the slopes is not required, because the plane is characterized by a structure that is exactly similar to metal.plastic products.
  • Drywall over time is subject to cracking and wetting under the influence of moisture presented in the form of condensate. Sandwich panels for window slopes always remain waterproof and do not destroy.
  • If the insulation of sandwich panels is needed, then this is more likely in the measures of reinsurance, because the material does not miss the cold at all. Experts often carry out such measures with the aim of immobilizing and strengthening the design on the window.
  • Cleaning sandwich panels is not difficult, a rag moistened in soapy solution, dust, dirt and even coffee spots are rubbed. If this has not helped, it is allowed to use the detergent that is usually washed, but without the presence of abrasive substance.
  • The installation is reduced to a simple and understandable procedure, thus, even a beginner in construction will be able to cope with the installation.
  • The life declared by the manufacturer ranges from 15 to 20 years. The slopes are not afraid of hail, strong wind and rain.

It’s time to discuss the minuses of sandwich panels. Rather, they are associated with the low quality of the proposed material, so when buying, pay attention to the manufacturer, do not be afraid to ask the seller-consultant inconvenient questions and demand to show certification.

Turn to the quality of the panel material

This is in your interests, because low.quality panels under the influence of sultry weather and high temperatures acquire a yellow tint, which cannot be eliminated and deformed, therefore they are considered extremely unreliable and brittle.

Much depends on the diligence and responsibility of the one who set to install the slopes from the sandwich panels. A careless attitude, haste and mismatch of the installation technology can subsequently lead to the formation of voids between panels and the windowsill.

Sandwitch slopes device

Studying the device of the internal structure allows us to conclude that slopes from sandwich panels are very similar to the usual plastic. If you pay attention to the functional component of these two copies, then you will understand that their technical characteristics are also identical.

To make slopes from sandwich panels with your own hands, you will have to collect a few components of the product into one, namely:

  • Profile made of plastic, presented in the P-shaped form. Its other name is the starting profile, because it is from its installation that the installation of the device originates. Fixation occurs directly around the perimeter of the window box, creating the right connection of the slopes with each other and with other important windows of the window.
  • A sandwich panel is a composite where polyurethane or polystyrene is located in the center between the plates made of plastic. The thickness of the panel can be very diverse. from 10 to 32 mm inclusive. Which model is suitable in this particular case depends on the free area coming from the edge of the window box to its end. Experts recommend using a universal device, the thickness of which is 24 mm.
  • Platband-plastic profile taking F-shaped. The difference from the starting profile is that the platband additionally has a protruding wide part, blocking the joint, which forms during the installation of the structure between the sheet and the angle of the window, which is located on the outer side.

Masters use other methods of arranging sandwich panels. In most cases, brackets fixing the front of the panel due to the attachment of platforms from the type of rail are used. This type of slopes is called European, and the assembly process is more like a designer that allows you to turn the installation of slopes from sandwich panels into a light and fast procedure.

Users have high hopes on plastic windows, products should protect the home from piercing wind, frost, atmospheric precipitation. To implement the planned finishing work, you need to prepare:

  • Electric screwdriver.
  • Sharp knife.
  • Fasteners.
  • Lobby.
  • Pencil, ruler.
  • Roulette.
  • Sealant.
  • F-shaped profile.
  • Construction bucket.
  • Gloves.
  • Profile P-shaped type.
  • Sealant.

Standard set of tools

Corner grinder (angular grinder)

Not every corner grinder is suitable for cutting panels. She must be small so that you easily hold it with one hand. The large corner grinder cannot be used.

The thinnest disk 0.8 mm, 1 mm or a maximum of 1.2 mm is installed in the corner grinder. The disc is used for metal.

The corner grinder gives an amazingly even cut, without a zazubrin and, as they say, the people are “snot”.

Corner grinder does not tear plastic. No matter what part of the panel you cut and in what weather. And in the cold and in the heat. Using a corner grinder, you will get an even cut.

Using a corner grinder from the wall panel, you can cut down literally millimeters.

The disadvantages belongs to the fact that it is heavier than the jigsaw and even more so the knife. But the biggest minus. Corner grinder gives a lot of fine dust. She gets to all places.

How to fix a sandwich panel. Where to start installation work

The fastening of the sandwich panels is carried out directly not to the surface, but on a special supporting structure. a frame from a certain material.

The main point when building the frame should be the fact that its vertical and horizontal steps should correspond to the size of the sandwich panels. Of course, all the rails should be oriented strictly in level, otherwise all the material will skew or begin to gather.

Since the cladding will be placed with joints and retreats from edges of 5 cm, these features must be provided for when installing the frame under the sandwich panel.

A frame of metal beams and profile

First of all, you need to clean the surface of any pollution, whether it is dirt or dust. Then it is treated with antiseptics and a layer of anti.corrosion composition. For subsequent work, you need to choose which frame will be built.

Carrying structures are the following types:

  • A wooden frame is the most affordable, but at the same time the most fire hazardous option. For fastening in this case, ordinary screws for wood panels are used for wood.
  • Reinforced concrete frame is a strong, but heavy option that is not suitable for any type of foundation. For fastening, dowels and anchors are used.
  • Metal frame is the most preferred option in which the installation of wall sandwich panels will be in the best way. For fastening in this case, self.extinguishing screws will be used. Before their screwing, the supporting elements are pre.drilling holes of a slightly smaller diameter than necessary. The screws are later twisted into these holes.

How to cut windows for windows. Installation of corners on window slopes or doors

Having dealt with what such products are made of, what are their features and having decided on the choice, you should study how to install corners on slopes. Detailed instructions are given below.

What glue to use

In addition to the corners themselves, we will also need an adhesive with which we will attach the selected element. When choosing it, it is worth remembering that quite often, especially if it is necessary to glue a narrow product, the glue seeps from under it and, of course, falls on the walls. As a result of this, the latter can be damaged, which, accordingly, will negatively affect the appearance of the room as a whole. Therefore, you should choose such an adhesive composition, the excess of which can be removed from the surface.

Basically, the corners are glued to new slopes, but nevertheless, check that the surface is relatively flat, since no decoration will be able to hide large hillocks. It should not have foreign objects like nails, screws, etc. D. It also needs to be degreased, for this purpose, white spite.

How to cut it correctly

Before discussing how to fix the corners on slopes, you should find out how to cut them correctly. After all, this stage of everything is the most time.consuming and, perhaps, even the most important, since it depends on how their edges will joke, and this directly affects the aesthetic appearance of the entire room. It is best to cut with a hacksaw with a small tooth. First you need to measure the length of the opening, then apply the marks to the corner so that the segment corresponds to this parameter. Then the part that will fit directly to the slope is cut strictly according to the marks, and the one that to the wall is at an angle of 45 °.

To cut the corner, use a hacksaw with small teeth

How to glue

Finally, we got to the main question of how to stick corners on slopes. However, before proceeding directly to fixation, it should be carried out, so to speak, fitting. After making sure that everything is cut correctly, you can move on. Apply to the inside of the corner, at the junction of the sides, gluing a solution with a step of approximately 10 cm. At this stage, an indispensable assistant will be a mounting gun. After that, quickly press the product to the surface and fix it in this position with a painting tape. You should start with a horizontal slope, and then proceed to the side. Remove the excess sealant from the surface of the walls with a damp cloth and let it dry well. You can remove adhesive tape only after 24 hours.

Sandwich window panels. A few words about sandwich panels

Sandwich panels for slopes for windows consist of two plastic sheets, between which the insulation is located. As the latter can be used:

Due to the presence of insulation, the amount of heat loss through the window opening decreases. As for the plastic itself, it happens in a variety of colors. This allows you to choose the panels for any window.

Many people believe that a sandwich panel for plastic windows is designed, however, they can also be used for wooden glass packets. Thanks to this decoration, they will not freeze.

Another advantage of this decision is that the windows in the sandwich panels do not fog (subject to normal humidity indoors). In addition, the material is easily mounted, which you can verify below, and also does not require additional finishing, which is also a big plus of it.

Thus, the finish of the sandwich panels of the windows is one of the best solutions.

I note that there are still metal sandwich panels, which are often used to build all kinds of everyday life, hangars, etc. Installation of PVC windows in a sandwich panel is associated with a number of difficulties.

Most often, for this, the opening is sheathed with a profile or board (if the room is heated), and only after that the windows are installed in the sandwich panel. However, this is already the topic of another article, which we will talk about next time.

After the installation of the window is completed in the sandwich panel, the coached area on the outside must be immediately hidden with platbands, otherwise the foam under the influence of sunlight will quickly turn into a dust.
