How to make slopes for plastic windows correctly - 4 ways with instructions!

At one installation of PVC frame with double-glazed windows, the work with the window opening is not completed - it is necessary to create a frame for it, both from the outside and from the inside. There are several ways to do this, differing in the materials used and working methods. Do you want to know more about them and understand how to correctly make slopes for plastic windows? Then here you will find a fairly detailed description of these methods with step-by-step instructions for performing the work.

Slopes for plastic windows do it yourself

But first, let's consider several reasons why it becomes necessary to mount slopes on plastic windows.

  1. The first reason is to protect the edges of the frame and the foam, on which it is held, from damage by dampness and temperature changes.

    Without slopes, the installation seam of the window will gradually collapse and become unusable.

  2. The second reason is the protection of the window opening from cold, rain and drafts, high-quality slopes made of metal, plastic or any other material will provide reliable thermal insulation at the assembly seam and prevent water from penetrating inside. Also, the slopes partially play the role of noise insulation
  3. The third reason is decorative. A plastic window in an opening without slopes does not look very beautiful both from the inside and from the outside. Therefore, it is framed with metal, plastic, drywall or plaster.

External metal slopes for plastic windows - installation instructions

During the construction of private housing in villages, townships and suburbs, slopes made of metal have become very popular.

This is largely due to their advantages over other materials.

  1. High strength - metal slopes withstand mechanical loads better than similar products made of other materials.

    Remember that improperly designed window finishes will lead to many troubles

  2. Durability - powder coated metal paint, is able to serve the owner of the house for many years, while not losing its strength and appearance.
  3. Resistance to high and very low temperatures - the metal will not deform under strong heating, it will not become extremely brittle in severe frosts.
  4. Attractive and neat appearance .

  5. Easy to install - metal slopes on a plastic window do not require much effort and time for installation.

Important! Also, do not forget to prepare a large enough work table on which it will be convenient to trim individual elements of the metal slope. In addition, if the upper border of the opening is high, take a stepladder.

Now let's move on to the direct description of the actions that must be performed to mount external metal slopes on plastic windows.

Step 1.

Unpack the set of slopes on plastic windows. Check if all its components are in stock and without defects. In this case, the kit consists of fasteners, a lower ebb, one upper and two side slopes, starting profiles for them.

Unpacking the slopes

Step 2. Measure the width and height of the window opening.

In this case, one must also take into account how correctly the window is installed - in some cases they are mounted in a plane that is not parallel to the outer wall of the house and the decoration. A similar factor must be taken into account when adjusting the lower ebb and other slopes further.

Fitting the bottom flange

Important! It will also be useful to "try on" individual elements of the slopes on plastic windows, installing them in the opening without fixing.

Step 3. Transfer the measurement results to the lower ebb, which is usually initially slightly larger than the width of the window opening.

You will subsequently cut this detail to the desired size, formed lateral "ears" at the edges.

How to make slopes for plastic windows correctly - 4 ways with instructions!

The measurement results are transferred to the lower ebb

Step 4. Cut the lower ebb with metal scissors along the width of the window opening, while leaving at the ends of the "ears" in the form of a trapezoid. Then fold them up, as shown in one of the photos below. Also leave a triangle on the outside of the ebb during the trimming process - it will cover the corner of the opening.

This is how the edge of the lower ebb should look like after trimming - a side bent surface in the form of a trapezoid is formed and a triangular edge is left, which will close the corner of the opening from the outside

Step 5. Check if the bottom sill is now the right size for the window opening. If everything is in order, mark the holes for the fasteners and drill them (if they were not made in advance, as on the product from the example in the photo).

Attaching the upper decorative element

Important! Factory-made metal slopes, as a rule, have a special plastic film that protects the product from scratches and other damage during storage and transportation. When installing, remove the film from those surfaces where it will be impossible to get rid of it later. Rip off the remnants of the film from other places only after the installation of the slopes is complete - this way you will reduce the chance of accidentally damaging the elements during the work.

Step 10. Using the vertical "lugs" on the upper and lower elements of the metal slopes, fix the starting side profiles.

Internal plaster slopes for plastic windows - step by step instructions

When decorating plastic windows indoors, owners of houses and apartments have a desire not to resort to plastic or metal products - these stand out too much inside the room and are more suitable for the outside. In this situation, the slopes are made of plaster - it can later be painted either in a neutral white color, or to match the design of the living room or kitchen.

Important! Keep in mind that plaster slopes are inferior in durability to plastic / metal ebbs and platbands and that they are not suitable for rooms with high humidity levels.

Step 1. Protect the glass and frames from plaster by temporarily applying plastic wrap to them. Also, in some places, it is advisable to use masking tape - this way you will free yourself from the need to subsequently clean the window from trapped pieces of plaster.

The window is sealed with a film

Step 2.

Using a pencil, make initial measurements of how it will be applied plaster. The mixture should partially cover the plastic window frame itself - this will minimize any possibility of draft. In this case, plaster slopes are also made at dawn - the surfaces are located at an angle, expanding from the window into the interior of the room. This is how the best illumination of the room is achieved.

Taking initial measurements

Step 3.

Complete the marks using a laser level for drawing either its usual bubble counterpart. In this case, it is necessary to indicate several points for screwing in the self-tapping screws and drill holes there - the fasteners will become a kind of substrate for beacons installed in the middle of the opening planes.

Preparing the beacons

Step 6.

Prepare a sufficiently dense and good mortar to attach the beacons to the surfaces of the window opening. Apply a few "cakes" of the mixture to each of them with a spatula. Then mount the lighthouse, using the caps of the screws screwed earlier as a substrate - the metal product will not pass further than them. Dip the beacon lightly in the solution.

Step 11.

Take a wide trowel and, leaning it against the plaster, the beacon on one side and rule on the other, even out the mixture and give it smoothness. Repeat this operation with the other sides of the window opening.

Leveling the plaster mixture

Important! Before the mixture dries completely, craftsmen often remove metal beacons so that they do not remain rusty inside the slopes. The grooves remaining after this are rubbed with a mixture and smoothed with a spatula in the same way as in the previous operation.

Step 12.

Work fine details and defects with narrow spatulas. After that, you can leave the plaster to dry. Then remove the protective plastic film from the window. The final touch is painting the new plaster slope in the desired color.

Plastic slopes on a wooden window

One of the most commonly used ways to make internal or external slopes on a window is plastic panels. Let's briefly consider one of the simplest ways to mount them - using the starting and other profiles. Such plastic slopes can be successfully used for both interior and exterior decoration of PVC windows.

Slope of drywall sheets - step by step instructions

Another the option of slopes for plastic windows - from drywall sheets.

Such a construction comes out quite strong and durable, plus - suitable for painting. But at the same time it has a considerable mass, and its installation requires some skills in working with this material. As a rule, such slopes are used in the event that both the walls and the ceiling in the room are also finished with plasterboard.

Important! Slopes made of plasterboard brands that are resistant to temperature extremes and high humidity can also be suitable for the exterior decoration of a window opening.

Step 1.

Take the dimensions of the window opening and calculate the slopes of what height and width you need. Mill drywall sheets so that their edges are at an angle - this is necessary for gluing the material into the corners, which will then act as slopes for the plastic window.
