Let’s not argue that if you frame Plastic corners are made by hot-bending a sheet of polyvinyl chloride. In general, they have the same width of the shelves from 10 to 40 mm with a step of 5 mm. However, there are asymmetrical copies, such as 10×25 mm, but regardless of this parameter, the angle between the sides is 90 degrees. If it is necessary to transform the arched opening, it is done by means of a special flexible profile. Their advantages include a relatively low cost, they do not need to be painted, unlike the same wood.

The next type. corners made of cork. Such decorative elements are quite often used for arched openings, but this does not mean that their use is limited to this area. They can also be used to decorate soffits of various shapes. Cork has a number of advantages, including durability, fire resistance, practicality and environmental friendliness. In principle, this material has almost no disadvantages, except that if your pet wants to sharpen the claws on it, it will damage the surface.

Also note the wooden and bamboo products, which will always be a sign of excellent taste and fit into almost any interior. In addition, we should not forget about their environmental friendliness. True, such elements are somewhat more expensive than their counterparts from other materials, but also often need to be painted. Even with natural wood can be compared and a material such as wood-fiber board, but it costs much lower, because for its creation using wood dust.

This can damage the latter and consequently have a negative effect on the appearance of the room as a whole. Therefore, you should choose a glue composition, the excess of which can be removed from the surface.

Mostly the corners are glued to the new soffits, but make sure the surface is relatively flat, because the big bumps will not be covered by any trim. It should be free of foreign objects like nails, self-tapping screws, etc. д. It is also necessary to degrease it, for this purpose white spirit is suitable.

Then the part that will adjoin directly to the slope, cut off strictly on the marks, and the part that is to the wall. at an angle of 45 °.

To trim the corner, use a fine-toothed hacksaw

Here, finally, we got to the main question, how to glue the corners on the slopes. However, before proceeding directly to the fixation, should carry out, so to speak, trying it on. After making sure that everything is trimmed correctly, you can go further. Apply glue mortar to the inside of the corner, at the junction of the sides, with a spacing of approximately 10 cm. At this stage an indispensable assistant will be a mounting pistol. After that, quickly press the product to the surface and fix it in that position with masking tape.

The photo shows the junction of baseboards in the inner corner of the room.

Floor skirting is represented by a very wide range of products:

  • Of PVC foam, plastic, produced with cable-channel for wiring and in their absence.
  • Of wood, made of various types of wood, solid or otherwise laminated; the installation of wooden baseboards is no different from the installation of plastic trim.
  • Iron, iron and dural, with cable channels and flat.

Complemented by plastic or iron products are different connections and endings, with which easy to perform the installation. So it is actually never a question of how to cut plastic skirting boards at the junction. Made of wood are devoid of such connecting parts. They need to be notched for a perfect connection.

Principle. The height of the walls of the machine should overlap the height of the trim strips to get a smooth cut.

Fixture for sawing moldings, the arrows show the technological slots for work in accordance with the annotation.

  • prepare two pieces of the river to join;
  • take the 1st piece, insert it into the jig from the right to the left so that it lies on the reason, as on the floor and leaning against the far wall of the fixture, as against the wall;
  • sawing the piece from the left end, passing the saw through the holes number 1;
  • The 2nd piece is inserted into the device from left to right, exactly adhering to the orientation of the floor and wall;
  • sawing it from the right end, passing the saw through the holes at number 3.5.

Recommendations of professionals

Useful tips to help beginners when installing with their own hands.

  • Be precise when marking so that there are no gaps between the joints. To prevent this, you can increase the length of the workpiece by 0.5-1 mm. They will still fit in place due to the elasticity of the material.

What to cut the plastic slope at the window

When working with this material, you must be careful when mechanically impacting it, such as when cutting. The material is quite fragile, and you can damage the sheet if you do not calculate the force.

Sandwich panels should be handled carefully so as not to damage the property.

Due to the lack of space between the window hinge and the wall, this material cannot be installed. It is important to note that the window opening when using this material will be reduced on both sides by the thickness of the panels.

Advantages over other finishes

If you plan to handle the slopes of plastic windows with your own hands, it is best to insulate the panels.

Using other materials such as Fibreboard would look strange. With a plastic window frame, the trim element of the same material will look more harmonious.

Preparing for the job

To install sandwich panel slopes with your own hands, you will need the following tools and devices:

  • Several trowels of different sizes and drawer boxes so that you can cut the plate at the right angle;
  • A jigsaw or metal hacksaw;
  • Screwdrivers or screwdrivers;
  • Measurers in the form of a level and a tape measure;
  • “Liquid nails and a gun for them;
  • A furniture stapler.

Before installing warm slopes, it is necessary to prepare a number of tools

Before installing the sandwich panel for the slopes must be prepared:

  • Window sills and plastic windows should be covered with polyethylene or cardboard;
  • The wall surface is checked for mold or moisture;
  • Use a stationery knife to cut off excess foam;
  • At this stage, it is important to assess the strength of the foundation, if it is partially destroyed, it must be rebuilt;

Before installing the panels, you need to clear the window openings

Installation of sandwich panel slopes will be done qualitatively with the correct measurement of the opening.

Installing

Independent lining sandwich panels on plastic windows are made in three ways: with foam, liquid nails or lining.

Installing the slope with installation foam. easiest

Anyone who has done foam installation knows that this method is the easiest. Slope for a window made of sandwich panels is mounted in several steps:

After the measurements are taken, the starting profile is installed. Then you need to transfer the dimensions to a sheet of cladding material and cut out the necessary elements;

According to the measurements, they cut the cladding sheets

The gap between the wall and the panel is filled with a thin layer of foam

Treatment of joints is done with sealant

It is important to know that the treatment of the lining should not be postponed indefinitely, but should be carried out immediately after the foam dries
