First of all, let’s find out what slopes are and why they are installed.
The bevel is the part of the window opening that is between the frame and the wall. It connects the structure of the plastic window and the wall of the apartment. They are a very important element when installing windows: they protect against any weather phenomena.
The most important function of slopes is vapor-water insulation. Most problems with windows appear due to small droplets of moisture that form in the air when temperatures change. This leads to such consequences as mold near the windows, condensation, dampness in the room. High-quality and correctly installed slopes can solve this problem. They also increase the preservation of heat in the room, preventing warm air from escaping through the windows.
Their outstanding property is also noise insulation of windows. This will be especially appreciated by those who live near noisy highways, tramways or busy streets.
In addition, slopes look very aesthetic and decorate your window opening. It is desirable that they be of the same quality and material as the window. Then they will be better combined. In addition, it will eliminate the problem of temperature difference.
Choose the most durable materials. Do not skimp on this item. By saving when buying. You will pay more later when there are problems with the slopes, which will quickly become unusable.
There are many types of slopes. The following materials are most often used: plastic, plasterboard, cork, plaster, wood. If, for example, you want plastic slopes, but you don’t like the white color, then the slopes and the plastic windows themselves can be painted in any color or pattern.
Each type has its advantages and disadvantages. You should choose one or another slope depending on where you will install it (this is almost the same as choosing plastic anlin windows). Plastic ones are most often used in practice. They are easy to manufacture and are more aesthetically pleasing. Also, plastic does not emit any harmful substances and is completely harmless. In addition, it has increased thermal insulation due to its structure.
As a rule, a layer of foam is laid between the construction of the slope and the wall, which increases all its properties.
It is best to invite specialists to install slopes. Only they know all the subtleties of this matter. If you decide to do it yourself, you risk damaging not only the slopes themselves, but also the windows.
In the process of repairing their own house or apartment, every citizen is faced with the opportunity to carry out part of the process independently. And many people use it, because there is a real opportunity to save a little. For example, installation of plasterboard slopes with your own hands. Why from this material? It’s all about its operational and technical characteristics, since GKL is an almost ready slope, even and does not require complex finishing works.
Of course, it would be possible to make slopes from plaster mortar, as it was done twenty years ago. But this process is difficult, dirty, and takes a lot of time. And without experience, you cannot conduct it yourself. Unlike him, even a novice can handle the production of slopes from plasterboard. The main thing is to know the technology and nuances of the installation process.
I would like to note that there are several ways to properly make drywall slopes with your own hands. Let’s consider several basic and simple options.
Plasterboard slope on the frame
We will make a condition right away that two mandatory operations must be present in the use of any method:
Installation of vapor barrier tape around the perimeter of the window opening. It should cover the foamed gap between the window and the opening.
Treatment of the concrete surface of the hole with an antiseptic solution. This will prevent the appearance and spread of fungi and mold in the area of the window.
As for the frame, it can be made from wooden slats 15-20 mm thick. Although the choice of thickness is based on the distance from the window frame to the concrete surface of the opening. The thickness of the plasterboard is subtracted from this distance, and this is the thickness of the rail.
Crate elements are installed along the perimeter of the site. And then definitely a few more bars across. The quantity is determined by the distance between them of 40 cm. But now the mandatory procedure is the treatment of wooden products with an antiseptic solution.
Insulation must be laid in the space between the racks of the frame. It can be mineral wool or foam. After that, you can install the plasterboard slope itself. Of course, you must first cut it out of the sheet. Therefore, we measure the dimensions of the plane of the installed grating, be sure to take into account the shape (it can be rectangular), transfer them to the sheet and cut out the area with a sharp knife.
Installation
It is necessary to install the plasterboard window bevel exactly along the frame, press it tightly to the window frame. The fewer all kinds of gaps, the less you will have to correct flaws. Now the product is attached to the wooden frame with self-tapping screws. At the same time, the following is taken into account:
- the distance between self-tapping screws is 10-12 cm;
- the distance from the place of installation of the self-tapping screw to the edge is 1.0-1.5 cm;
- the cap of the self-tapping screw should be deepened by 0.5 mm;
- fastening is carried out along the perimeter and across the transverse elements;
- first, in this way, the upper element is mounted, then the two side ones.
Installation on foam
Mounting foam is also a good adhesive. In addition, it has excellent thermal insulation qualities. Therefore, there is a technology for arranging slopes from plasterboard, which uses foam. But these are not the only reasons for which this technology is used. For example, if it is not possible to install a frame, there is a small distance from the frame to the plane of the hole. Or the wall is made of porous material in which dowels do not hold.
The process itself is carried out as follows:
- In the foamed gap between the frame and the slot, a groove with a width equal to the thickness of the plasterboard slope and a depth of 1 cm is made.
- The strip is inserted into it and foamed with a layer closer to the window frame.
- Then another layer is applied closer to the middle. And the last to the outer edge. At the same time, you need to press the plasterboard slope with your own hands. The foam expands and will press on the walls of the strip.
It is recommended to make such a bevel more than 5 cm wide. This will create convenience during installation and will allow the foam to expand freely. The protruding part of the foam and sheets of material can be cut with a sharp knife after solidification.
Installation of window plasterboard construction on glue
And another simple technique for installing window slopes from plasterboard with your own hands. For this, it is best to use Perflix glue.
An adhesive composition is applied to the finished workpiece from the inside along the rear edge to a width of 10 cm. On another area, glue is applied point by point every 30 cm. Now the prepared plasterboard window slope must be tightly pressed to the concrete surface.
Please note that the upper element can be pressed with a support, the side elements will have to be put on two or three self-tapping screws, which can be removed after gluing. In addition, the side slopes made of plasterboard with your own hands on the windows are installed under the upper one, so that they will also perform the functions of supports.
The remaining external gap between the wall and the inner side of the strip must be filled with adhesive. For this, the adhesive material is pressed with a spatula until the free space is completely filled.
There are different technologies that additionally use different fastening parts. For example, installation with the help of a special beveled corner or with the help of a starting profile. It is possible to build a frame structure from metal profiles. For those who decide to do it for the first time, it is recommended to use simple methods. A complex construction is not only a big expense, but it takes a lot of time to build. In addition, there is always the possibility of making a mistake somewhere, which will lead to rework, and therefore to spending money.
