Do-it-yourself installation of slopes from plastic sandwich panels on windows

Further actions

All excess gaps must be rubbed and leveled. Excess acrylic must be removed with a damp cloth or sponge. This must be done carefully until the surface is completely clean. The manipulation is carried out in small areas. Acrylic must not be allowed to harden, otherwise there will be problems with its removal. It is more convenient to seal the cracks right away. The horizontal slope panel is processed first. After that, there are joints, then they move down. First, the gaps are closed on one side, then on the opposite. Last but not least, the joints with the window sill are processed.

Drying takes 12 to 24 hours, depending on the characteristics of the sealant. If the gaps are large, the acrylic can be pulled into the seam. All these areas need to be reworked using the same technique. After the second layer has dried, in the presence of irregularities and roughness, these defects can be smoothed out with fine-grained emery paper, folding it in half. It is recommended to carefully level the materials while they are gray, otherwise the plastic may get mechanical damage.

Slopes can be considered established. They should be putty when the foam has completely polymerized. Their surface should be flat relative to the plane of the walls. The protective blue film is then removed.

Panels are considered the most unreliable material for mounting plastic slopes. Even the wall ones are easily squeezed through, and their front layer is imperfect. It is enough to direct light on them, as the jumpers will be immediately visible. This is not observed in plastic window sills and sandwich panels.

Installation features and types of building structures

Ready-made material can be purchased at the store. Sandwich panels are presented in several types: wall, roof and stage-by-stage assembly models. In construction, wall panels are most often used. Their light weight does not put pressure on the foundation of the building. When using panels in the roof, specially designed roof panels are used.

The core of the filler between the sheets is a mineral board. Stage-by-stage sandwich panels are a structure designed to be attached to the building frame. Such structures do not have strength and a small chance of fire.

One of the important components of the panel is a durable polyurethane adhesive. It comes in two types: one-component and two-component. One-component glue hardens on contact with air, and two-component glue - due to a chemical reaction between its two components. It is more durable than one-part adhesive. The life of the quick-drying adhesive can be extended by lowering the room temperature.

In the form of an insulation layer for sandwich panels, the following can be used:

mineral wool;
polyurethane foam;
expanded polystyrene;
polypropylene;
polyisocyanurate;
fiberglass.

In the form of a frame sheet material, the following can be used:

an alloy of aluminum and zinc;
Cink Steel;
drywall;
hard plastic;
polyester;
polydifluorionad;
pural;
oriented strand board;
wood;
fiberboard.

Often, panels are used in the renovation of city apartments. They can act as the inner walls of the window opening for new plastic windows. Such panels are extremely useful for thermal insulation and soundproofing of an apartment, and also do not allow blowing.

Material features

It is important to purchase high-quality material, since otherwise, under the influence of direct sunlight, the panels may lose their shape and turn yellow

When working with this material, care should be taken with mechanical stress on it, for example, cutting. The material is quite fragile and the sheet can be damaged if the forces are not calculated

The material is quite fragile and the sheet can be damaged if the forces are not calculated

When working with this material, care should be taken with mechanical stress, for example, cutting. The material is quite fragile and the sheet can be damaged if the forces are not calculated

Sandwich panels should be handled with care to avoid material damage.

If there is not enough space between the window hinge and the wall, this material cannot be installed

It is important to take into account that the window opening when using this material will decrease on both sides by the thickness of the panels

Transportation of products can be difficult as the sheets are large. However, some stores cut them into smaller pieces.

How to cut to the correct size

Starting repair work, every builder is faced with the main task - the correct measurement measures. Indeed, the integrity of the structure and its attractive appearance will depend on the quality of the selected dimensions and finished cut sheets. Therefore, the preparation of SIP plates should be done as follows:

First, you need to prepare the surface for the installation of slopes, level the walls, cut off excess assembly materials after installing the window or doors;
Then the stage of measurements and data transfer to the layers of construction products is carried out.
It is necessary to carry out measuring work in stages, first at the top, from corner to corner and depth, then with the help of devices for cutting SIP panels (a jigsaw is quite suitable), cut off the desired size of the plate.
Using the building level, it is necessary to attach the finished sandwich panel to the future slope and see if the product fits snugly against the wall, at the right angle or not.
If everything is done correctly, the same manipulations are made with the side walls and the bottom (if necessary) of the opening.
When transferring the data of the width of the slope to a multi-layer building sheet, 10mm must be added to this indicator. This is necessary for high-quality pairing of the product with the window frame.

Important to remember! In order for the design of the slopes to have a beautiful integral appearance, the plates of sandwich panels of strictly measured width should be cut so that the plates do not protrude beyond the edges of the walls. In this case, after finishing, the wall will smoothly transition into the constructed slope.

Also, when carrying out measuring measures, the possible unevenness of the walls should be taken into account, therefore, measurements should be taken from the top, middle and bottom of the wall (or, respectively, in several sections of the upper and lower strip of the window and doorway).

Step-by-step installation guide

Preparatory work

To install sandwich panel slopes, you need to arm yourself with the right set of tools and materials. Useful for work:

Sandwich panel.
P-profile, which is the starting one.
F-profile is the so-called device cover.
Liquid plastic (preferred).
Construction tape.
Sharpened knife.
Self-tapping screws 2.5 * 7 mm.
Several screwdrivers with different tips, the drill can be replaced with a screwdriver.

Armed with a tape measure, measure the length and width of the slopes, this is the main reference point that determines the final dimensions of the sandwich panels for the slopes

Taking these values into account, cut out several strips with a knife: one will be located in the upper part of the window, and the remaining two will be on the sides.

Now let's talk about how to properly cut the elements of the sandwich device:

The width of the elements is set 10 mm more from the initial measurements of the window, this will provide a tighter contact with the frame.
Around the window frame, directly in the hardened foam, a hole should be cut, the depth of which is 100 mm and the width is 1 mm.
At the edge where the sandwich panel will be located, measure 10 mm and draw a line. Cut the material strictly along the line, but only grab the upper and insulation levels. How to cut a sandwich panel for slopes? You do not need a special tool for this, you can do with an ordinary kitchen knife.
Cut from the end, remove the excess layers.

If the finishing of the slopes with sandwich panels is planned in one place, you can try to save money and buy ready-made, cut strips without purchasing a solid panel.

The main part of the work

After preparing the necessary tools and materials, we move on to the main part of the slope installation process. First, we install the frame:

We carefully process the window frame - we get rid of excess foam, go through the structure with a cloth to clean it of dust and debris.
We distribute vapor barrier material over the entire area of the slopes. If you want to insulate the openings even more, use foam strips.
Apply an antiseptic agent to the coating with a brush, aerosol or directly from the tube (depending on the packaging), which in the future will protect the window from the appearance of mold, the growth of fungi and other harmful substances.
Focusing on the inside of the device, following the perimeter, install the lathing made of wood. The dimensions of the rack material are 20 * 40 mm. The rail is fixed with dowel-nails. Observe a distance of up to 40 mm. In the areas of the seams where the side and top battens of the crate dock, lay a gap of 10 mm or more - it will be needed to install PVC elements on the slopes at the top. If the frame cannot be secured, the sandwich panel cladding is fixed with foam.

Outer strips overlap

Installation of panels is always done from the top of the window frame, going to the bottom. Place the protruding element in the formed groove so that the part fits snugly against the window. Fill the free space with a material that will maintain the temperature and insulate the window structure from drafts, for this it is better to use isover.

The outer side is fastened using self-tapping screws, check the correct position of the upper trim using the building level. The side slopes are trimmed with special edging.

DIY PVC slopes installation

Like all construction work, the installation of plastic slopes begins with preliminary preparation, during which the materials and tools necessary for this work are purchased.

What materials and tools are needed:

P and F-shaped profiles

Plastic for slopes with a thickness of at least 8 mm.
U-shaped starter strip made of plastic.
F-shaped plastic profile.
Insulation material: mineral wool, polyurethane foam.
Wooden lath.
Drill for self-tapping screws.
Building level.
Roulette.
Putty knife.
Cement mortar.
Self-tapping screws are long - 95 mm, self-tapping bugs - 4.5 mm.
Painting knife.
Silicone sealant.
Scissors for metal.
Construction stapler.

Next, the working surface is prepared: the remnants of wallpaper or old plaster are removed from the old slopes, the surface is treated with an antifungal agent. If, during the installation of a metal-plastic window from the street side, gaps have formed, they must be sealed with cement mortar. This procedure is necessary to close the polyurethane foam from the sun's damaging rays and to seal the external assembly seams.

Stages of installation of plastic slopes

First of all, wooden slats are installed on the top and sides of the window openings. They are fixed with long screws (95 mm) and fixed in such a way that their edge does not protrude beyond the level of the wall.The screw holes are drilled with a drill. The screws are initially not fully tightened. Having designed all sides of the window opening in this way, we check the position of the battens with the building level. This is necessary to create perfectly flat slopes. Then the screws are tightened to the end.
The starting U-shaped strip is attached with the help of self-tapping bugs along the outer edge of the window. The joints of the U-shaped stripes should be even and smooth, small protrusions are cut off with a painting knife. The U-shaped profile has a gutter into which a plastic slope will be inserted.
Next, you need to install the F-shaped profile. The installation of this profile should be done so that its groove is installed opposite the groove of the U-shaped starting strip. The F-profile groove above the window must be cut off. The upper part of this profile is overlapped. After precise joining, the excess parts of the F-strips are cut with metal scissors. The F-profile is attached to the wooden battens with a construction stapler. The part of the end of the profile that is closer to the wooden rail is attached. The F-profile is primarily used as a decorative element.
Now you can proceed to installing the panels in the grooves. But before that, it is required to measure with the utmost precision and also precisely cut off the plastic. Simultaneously with the installation of the slopes, mineral wool is laid. Care must be taken to ensure that the insulation lies flat. If the joints of the entire structure are not perfectly flat, you can use white silicone sealant to grout the defects.

Sandwich panels for window slopes can be installed using a slightly different technology. Its difference from the one described above is that after the installation of the starting profile, sandwich panels cut to size are immediately installed in it, the opposite edge of which is attached diagonally to the wooden slats with self-tapping screws. Next, the F-profiles are installed and the joints are covered with a sealant. How to do this work is clearly shown in the video.

We mount PVC slopes ourselves. Installation instructions.

This completes the installation of sandwich panel slopes. The result will delight you if, when doing your own work, you follow the following recommendations:

Start the installation of slopes from the top element.
If it becomes necessary to use polyurethane foam, remember that when it hardens, it expands and begins to put pressure on the structure.
Remove excess silicone sealant with a piece of plastic.
Choose plastic only with excellent quality indicators.
Before the installation of PVC slopes is completed, it is not recommended to remove the protective film from the window.
Leave it alone for 16 hours so that the plastic structure does not suffer or lose its integrity.
Carefully study the information on the correct installation of slopes and the sequence of stages of work.

Ready-made window slopes made of plastic

Installation of plastic slopes on DIY windowswithout using a start profile for this is another option. For this, a small recess is made around the perimeter of the window in the mounting foam, where the sandwich panel is then inserted. This technology is presented in the video.

Installation stages - the alphabet of construction work ↑

It will take no more than 2 hours to install plastic slopes with your own hands. In comparison, high-quality plastering work will take up to 3 days!

Plastic slopes are of two types:

decorative;
sandwich panels (insulated).

Decorative slopes are required in the following cases:

For formal partitions. That is, the design of window openings located between rooms (for example, in an office).
For finishing loggias. The outer slopes of the balcony block cannot be insulated. Because the panels cannot be inserted behind the frame.They are hindered by a quarter, laid out of bricks (its purpose is to prevent the window from falling out).

In all other cases, it is more correct to choose sandwich panels. They consist of two PVC sheets and a layer of insulation between them.

The standard thickness of the slope is 8 mm. But with careless installation, such a panel can easily be squeezed out with foam! Therefore, many craftsmen advise choosing thicker options (for example, 24 mm). This panel is difficult to cut, but it is also much stronger.

Basic rules for choosing panels:

Made from virgin plastic only. Such plastic slopes will not turn yellow over time, and their composition will not harm health.
With a thick layer of plastic. Cheap panels with thin PVC sheets quickly deteriorate. The plastic is simply peeled off the surface.

Window device

In addition to panels, you must definitely buy profiles - internal (J-profile) and external (C-profile). Together they form a strong anchor lock that tightly holds the slopes.

Installing plastic slopes with your own hands will also require other materials:

self-tapping screws 51 mm;
PVC dowels;
wooden slats;
Summer foam (2.6);
gypsum mixture for plaster;
mineral wool.

You will need the following tools:

drill;
screwdriver;
electric stapler;
putty knife;
assembly gun with the ability to normalize and adjust foaming.

The window sill must be installed at an angle of 3-5 °

To install plastic slopes with your own hands, use the step-by-step instructions:

The first step is to install the guides. For this, wooden slats 10x40 mm, self-tapping screws 51 mm and PVC dowels are suitable.
The slats must be fixed along the perimeter of the window strictly parallel to the frame. Drill holes through the guides (6-12 cm).
Insert dowels into the holes and tighten with self-tapping screws, sinking them to a depth of 5 mm.
Reinforce the slats with summer polyurethane foam.
Select a groove in the foam joint along the window frame 6 mm deep and 8 mm wide.

Slope slats

Groove in the assembly seam

Attach the connecting inner J-profile to the strips using staples 10-14 mm long. For fastening, a step of 10-25 cm is sufficient.

Internal J-profile

Attach plastic slopes. Form the foam joint. To do this, attach a plastic panel and fill the cavity evenly by 15%. Then fill the cavity to 70% with mineral wool. This will reduce heat loss and prevent mold.

Press the panels against the slats and fix them with brackets at an angle of 45 °. This will further increase the pressure and allow the plastic to be well pressed.

The percentage of filling with cotton from 30 to 70%

How to make a competent installation of plastic slopes with your own hands, you can see in the video.

Video: Installation of plastic slopes

Before installing the external profile, align the walls adjacent to the window. To do this, you need to remove the remnants of the old wallpaper and apply a quick-hardening mixture.

Then fit the outer C-profile and adjust it to size. To do this, measure the profiles and file them so that the lock is at an angle of 45 °.

Profile fitting

Pressing on the profile, secure it until it clicks. Saw through the plastic with a hacksaw both profiles at their intersection. This will make the seam as neat as possible. Move the corners to each other by tapping on them.

Drank with a hacksaw

At the end, clean the room, remove all dust and debris with a brush and rag. Degrease the joints and slightly moisten them. After that, apply decorative silicone-acrylic sealant.

The joints are invisible

Instructions on how to do it and where to start

You just need to know the theory and follow the instructions to make everything work out as it should! Prepare panels, tape measure, liquid plastic, knife, screws, screwdriver, drill, profile type F and P. Let's get to work, clean the surface of old plaster and dusty surface. Profile P is the starting profile, it is attached horizontally and vertically.Profile F is a casing, in shape it is the same as the starting one, but it has a wide strip in the structure, which is used to overlap assembly joints. The main thing is to correctly trim, without gaps and gaps.

First, the side blocks are cut and mounted in the groove, then the top. Factory accessories are used for docking and external decorative finishing. After the upper profile is installed, the extreme starting one is attached.

Sealing will not interfere, it will serve as a reliable additional fastener. Use a polyurethane based sealant for this purpose. All blocks for installation are cut exclusively at right angles, otherwise gaps will form in the corners, which will make it possible for air to enter the room, which means that there will be a draft in the room.

If necessary, use heat-insulating materials, they are placed in the inside of the structure, it can be mineral wool, foam.

Stages of installation work

Measures for the replacement of double-glazed windows are over and then work begins on the design of the adjacent walls. This procedure will take a small amount of time if you install sandwich panel slopes. To do this, you should purchase:

First of all, it is worth choosing a design and a certain type of multilayer products;
level, measuring tape;
Special knife for cutting SIP plates, drill or screwdriver, self-tapping screws;
Assembly glue or liquid plastic;
profiles type P and F.

Having prepared all of the above, the fastening of the plates begins. The most common and fastest way of installation work is as follows:

The perimeter of the opening is being prepared. With a sharp construction knife, you need to cut off the remnants of the fastening raw materials, level the surface for better fastening of the panels. The walls are cleared of construction debris and dust.
An important part of any construction process is counting and measuring all areas for further sandwich panel preparation. Cut the required size plates with a sharp knife.
Next, the U-profile is fastened using a drill, screwdriver and self-tapping screws. This is done first at the top of the structure, then on the sides and at the very end - at the bottom of the window opening.
The next stage is the installation itself. This must be done according to the same principle as the fasteners of the U-profile, using an adhesive solution, and self-tapping screws.
The finished structure is covered with a plate lid, which is an F-profile. This contributes to the fact that the design will look uniform and aesthetically pleasing.

For many installers, plate fastening is an ordinary action that is not carried out in a relatively short period of time. But having decided to carry out the installation process without resorting to the help of builders, you should responsibly approach the process of studying the nuances of technology so that the result justifies the invested forces and expectations.

Sandwich slope - can be done on any windows, wooden or plastic. The optimal block width for these purposes is 1 centimeter. Among the positive properties of the material:

Affordable cost;
Reliability;
Durability and long service life;
Soundproofing qualities;
Simple installation.

There are large color palettes that allow you to choose panels according to the decor of the room. They are matte, with a glossy shine, natural wood, marble, stone. For any interior, you can find a good solution for the improvement of window openings.

External slopes made of sandwich panels have many advantages:

High thermal insulation characteristics;
Possibility of installation in the shortest possible time;
Little weight.

Remove the old plaster, prime the surface, mark with dowels the lines along which the structure will be installed. Directly for the installation procedure, you will need liquid nails or polyurethane foam. After drying, the excess is cut off with a knife, decorative nozzles are put on the ends, edges.

Sandwich panels are considered one of the most demanded materials in modern construction and renovation. They have excellent characteristics, are easy to install and have thermal insulation properties, and also have a relatively low weight, so they do not require special strengthening of the foundation.

The design itself really resembles a sandwich (sandwich), since it consists of several layers:

Raw materials that are resistant to mechanical and other types of damage are taken as an external material. As a rule, it is galvanized steel or aluminum, as well as fiberboard and OSB.
For the inner layer, a dense, durable thick layer of insulation is most often taken. You can choose basalt fiber, expanded polystyrene, glass wool and other things that differ in thermal insulation properties.
Most often, in order for the sandwich panels to be maximally protected from temperature drops, exposure to ultraviolet radiation and other negative factors, the outer layer of the structure is impregnated with special means. And only after that, the SIP panels are ready for use.

Due to the fact that raw materials are used for production, which can be bought at any hardware store, it is possible to do the installation of sandwich panels with your own hands.

The popularity of sandwich panels is growing, because they can be used not only to insulate buildings, but also to construct them. For this reason, some homeowners decide to start making this structure on their own.

If you decide to insulate your house, you can design sandwich panels from OSB layers and glass wool. Do-it-yourself installation, of course, will take a long time, but the result will exceed expectations. You will receive high quality thermal insulation material.

Installation of sandwich panels

First of all, you should measure each slope and cut the panels to size. It is most convenient to cut a sandwich panel with an assembly knife.

To do this, lay the panel on the floor or trestles, mark it with a tape measure and a pencil. Then, pressing the rule, draw a line with the edge of the mounting knife, then repeat this operation 2 - 3 more times, trying to get into the first cut. Then place the rule underneath the edge of the panel and press lightly so that it folds over the cut. It remains to finally cut the PVC layer and foam, and then, using sandpaper, fixed on a bar or grater, level the edges of the cut.

The next step is to install side slopes. Using self-tapping screws, fix the pre-cut to size starting profile (U-shaped). Self-tapping screws are screwed in in 15 cm increments.

Then, on the panel, apply a zigzag strip of liquid nails in the middle and straight stripes around the perimeter. Insert the panel with one edge into the profile and press evenly against the slope. The second side panel and the upper slope are mounted in the same way.

For decorative finishing of the window opening, an edging profile is glued along the perimeter. To make the window look neat, you need to cut the joints in the corners at 45 degrees, it is most convenient to do this using a miter box.

When installing sandwich panels, one should try to install the component elements in such a way that the joints between them have a minimum gap. To mask the joints, they must be carefully filled with white sealant, or (and this is the best option), use a special liquid plastic.

Properly installed slopes are functional and easy to maintain, designed for many years of operation. The cladding material does not change color when exposed to sunlight. The color range of sandwich panels allows you to implement interesting design solutions, but in this case it is more difficult to choose a material for sealing the joints between the elements of facing window slopes.
