How to install a window sill: step-by-step instructions, installation features and recommendations

Often, when carrying out major repairs in the room, you have to change old windows. However, the installation of the window can not be considered complete without exterior finishing, installation of slopes and window sills. It is about how to install a window sill (the windows are already standing with this), we will speak in this material.

Common installation methods

There are several solutions that allow you to find the answer to the question of how to install the windowsill with your own hands:

1. The design can be secured by the use of an adhesive. This is an old enough method, which today is rarely used by masters due to the appearance of more reliable options.
2. One of the simplest solutions is the use of self-tapping screws. Fasteners are screwed into pre-prepared holes in the windowsill. The rigidity of the structure allows the use of special pads and mounting foam.
3. The following method assumes the use of spring metal clips as fasteners. The latter are screwed to the profile of the window sill with the help of the same self-tapping screws.
4. And, finally, the last method is to compact the space under the sill lining until the edges of the plane enter the window frame to achieve an increased density level.

Tools and materials

How to install a plastic window sill with your own hands in the most elementary way? This may require the following tools:

• building level;
• Screwdriver;
• Gun for laying assembly foam;
• Perforator;
• A jigsaw;
• pencil;
• Stationery knife ;
• roulette.

Preparatory activities

How to install a window sill? First of all it is necessary to prepare the above-mentioned tools, which are sure to be useful in the process of work. Next, you need to make the correct measurements. This directly affects the aesthetic appearance of the installed window sill and its reliability.

When performing measurements, it is important to take into account not only the parameters of the installed canvas, but also a whole list of additional characteristics. Particular attention here deserves the location of the existing radiator. If the latter is installed high enough, the presence of free space of a few centimeters to the bottom edge of the sill may lead to disruption of air circulation in the room and deterioration of the microclimate.

When performing measurements, it should be borne in mind that the length of the window sill should be larger than the space of the window opening. The width of the product can be chosen arbitrarily, depending on personal convenience and needs. A convenient option is a window sill that protrudes from the wall for a distance not exceeding 8-10 cm.

For installation, it is not recommended to choose a too thick sill. Determined with the dimensions, you should check how well the air circulates, which heats up from the radiator.

Trimming the windowsill

So, we consider further how to properly install the windowsill. Sometimes during the installation, the product needs to be trimmed so that the latter conforms to the parameters of the window opening. The most overall sills reach a length of 3 m or more. The width of the structure can be from 25 to 70 cm.

If the window sill is too large, excess material can be cut off from the side of the fastening to the wall. Particular attention here should be given to the cut line. It must pass, without touching the stiffeners, which are located inside the windowsill. Thus, the structure is not deformed during operation and will reliably connect to the frame.

To trim the sill, it is recommended to use electric jig saw. It is allowed to use a small hacksaw on wood or plastic, depending on the material of the construction. The work should be carried out slowly, which will avoid the appearance of chips and scratches on the front of the window sill.

Sawing products, do not forget about safety. Since splintered pieces of material can get into the eyes, it is recommended to perform work in the mounting glasses. To protect your hands, you should use gloves or work gloves.

How to install a plastic window sill: basic actions

The installation of plastic windowsills is quite simple:

1. First, a thorough cleaning of the surfaces is performed. Eliminate pollution, remove debris.
2. Using the building level, you must determine the horizontal position of the structure, set the beacons. Typically, when mounting the window sills, their plane tilts down about 5 mm. This solution allows the formed condensate to flow off the plane.
3. How to install window sills on plastic windows? The design sits on a special glue or mortar. As an alternative solution, you can resort to fixing the plane with screws on the mechanical supports.
4. At the next stage, the free space between the concrete slab and the window sill is filled with mounting foam. Outwardly protruding excesses are neatly cleaned with a clerical knife.
5. Finally, special end caps are installed on the end edges. The surface of the window sill eliminates the protective film.

How to install sills on plastic windows correctly? To do this, there should be a free distance of about 6-7 cm between the heating radiator and the bottom edge of the product plane. Only in this case, warm air will freely rise from the battery, drying the double-glazed windows and slopes.

How to install a window sill from a tree?

The installation of a wooden window sill is much more difficult. Before you start working, you should pay attention to the quality of the source material. The window sill should not contain obvious flaws in the form of chips, knots, other defects. Moreover, a well-dried board should be used. Otherwise, the latter may crack during operation under the influence of sudden temperature changes and changes in humidity level.

How to install a window sill in this case:

1. The existing base is scraped from all sides, and then on its back surface are created the water-splitters. The latter are small gutters 5-6 mm deep and 7-8 mm wide.
2. On the back surface of the board is laid a felt lining impregnated with antiseptics.
3. A prepared window sill is inserted into the openings in the wall. The spleen is installed on pre-prepared wooden bars. Elements of construction are fastened with nails.
4. The edges of the structure are strengthened with gypsum mortar.

Masters who are well versed in how to install a window sill made of wood are advised to perform a rather impressive slope inside the room, which should be about 20 mm. This avoids the accumulation of condensate on the surface of the product and prevents rotting of the material.

Mounting of slopes

After the installation of the window sill , slopes should be made. First of all, it is necessary to resort to aligning the window opening vertically and horizontally. The easiest way is to cope with the task using a mounting foam. The latter will serve as a good protection for slopes from freezing.

Surfaces can be reinforced with a mesh or plasterboard. The main task is the maximum leveling of the planes, as well as the formation of a smooth texture. Above the slopes can be covered with paint, focusing on choosing colors for interior solutions.

Helpful Tips

If the edge of the windowsill protrudes indoors for 10 cm or more in relation to the edge of the wall, it is recommended to strengthen the structure. In this regard, it is necessary to resort to the use of metal corners. But even when implementing such a solution, do not overload the edge of the windowsill during operation, as this can cause deformation of the plane.

Particular attention should be given to the installation conditions of the window sill on the balcony. To ensure that the surfaces are firmly "seized", it is desirable to maintain the air temperature in the range from +16 to +20 ^о С for several days.

A lot of mounting foam during the installation of the window sill is recommended to be applied on the ends and in the middle part of the product. To strengthen the construction it is allowed to use silicone sealants and glue.

Eventually

As you can see, installing the window sill with your own hands is quite a feasible task. The main thing is to carefully approach the work, not to miss the moments that can adversely affect the subsequent operation of the structure.

It is from the installation of window sills that the attractive appearance of the window aperture depends. Failure to install them will not only render the premises unclean in appearance, but also create some inconvenience. In particular, the owner of housing will have to regularly remove streaks of condensation formed on the windows. Otherwise, annual surface finish and renovation will be required.
