The advantages of a plastic window sill

The most popular materials for window sills: wood, plastic and stone.

• Wooden window sills are too picky and require constant care. In addition, over time, they are dry or damaged by frequent staining.
• Stone window sills are certainly durable and beautiful, but it is very expensive and cannot be installed independently.
• Plastic window sills are not just durable, light and beautiful, in their technical specifications they best coincide with the windows from PVC profile, which will make their care more simple.

• In addition, the operational period will be the same, so by mounting the window, slopes and window sills, you do not have to replace or restore one element.
• If the window frame has lamination, then the same film is selected for the windowsill.
• Due to its properties, plastic is resistant to moisture, so even with possible condensate on the windows it will not begin to rot. With regular care, mold does not form on it, since the surface does not have microcracks.
• The lower price than that of a wooden or stone windowsill of the same size.
• Resistant to an aggressive chemical environment.
• Due to the light weight and plasticity of the material, it is easily cut and installed independently without special tools.
• A plastic windowsill is not a cast slab. It consists of transverse cameras. This not only reduces weight, but also serve as additional thermal insulation.
• More expensive PVC window sills have a special coating, which makes it resistant to high temperatures and mechanical damage.

The disadvantage of them is only one low strength.

How plastic window sills are made

There are no official classification of plastic window sills, but they are conditionally divided into several types.

• Standard plastic window sills. They are the most popular. They are made in white, a width of 20 to 100 cm with a step of 5 cm. It has the lowest resistance to mechanical damage.

• Thermal and impact-resistant plastic window sills. Rationally mount them in wide openings that perform the function of the working surface. For example, when a kitchen window sill is used as a table. The product gives special strength to the product with a special film.
• Laminated window sills. They are more beautiful, but their characteristics remain the same. Films not only give the color the windowsill, but can also imitate natural materials (stone, wood). Despite the fact that the lamination method is reliable, a number of manufacturers are offered by window sills, which have an acrylic layer on top of lamination. In this case, the surface strength increases several times (however, as the cost and weight, too, that it is not to reduce its advantages).
• The panels are made by extrusion by extruder PVC-propeller. The surface is laminated by a film that gives the windowsill smoothness and further protects its surface from damage. The thickness of the window sill varies from 1.8 to 2.2 cm.

How to choose a plastic windowsill

At first glance, all window sills are the same and there is a desire to purchase the cheapest. But professionals know several nuances that will help you choose the highest quality product.

• The plastic windowsill should be made of high -quality raw materials, which has passed quality testing for security for humans. This can only be tracked by a certificate of products.
• Also in the store should provide detailed characteristics of the material. They include resistance to UV rays (especially important for colored products), mechanical strength and resistance to condensation.

Having received all the necessary information, they choose a model suitable in design and size.

• It is best to choose a white windowsill. This is due to the fact that it is guaranteed not to fade under the influence of direct sunlight. And small scratches on it will be almost invisible, unlike color models.

Tip: cheap plastic in a few years can turn yellow, so white window sills are recommended to be chosen from the average price segment.

• A plastic window sill, regardless of the price and manufacturer, is a panel, inside which stiffener ribs are 1.5 3 mm thick and air chambers between them. It is the number of ribs of stiffness that is responsible for the strength of the windowsill. The higher their number, the more he can withstand the load.
• The panel has a standard length of 600 cm. You can buy and cut them yourself, or order them already ready for individual sizes.

Tip: In order not to make a mistake in preliminary calculations, it is recommended to call the measurer.

• The width of the panels is from 20 to 100 cm. At first, the step towards the increase takes 5 cm, after 60 cm 10 cm. Based on this, the internal size of the window opening (depth) is measured. Since the windowsill should protrude forward (but not completely close the radiator), another 10 cm is added.
• For example, the depth of the window sill in a panel house is 15 cm, add another 10, and you get 25 cm the required panel width.

Preparation of walls before installing a plastic window sill

Before installing plastic window sills with your own hands, you need to prepare the walls.

• First, all garbage is removed from the window opening and it is exhausted that the installation foam later has the best adhesion. It is especially important to do this if the installation is made in return for the old wooden windowsill.
• The side walls of the window opening are called slopes. Often the windowsill is laid simply from edge to edge, but this is wrong. The secrets of installing the windowsill is to deepen it on the sides in the wall for 2-4 cm. For this, recesses are made by a perforator.

What you need to install PVC window sill

If the work is carried out in a wooden house, then the number of tools will be needed minimal, in concrete and brick houses it is more and more complicated.

• Punch;
• bulgarian;
• 1 m long level;
• mounting foam and gun for her;
• stationery knife;
• wedges (from MDF, laminate or wood).

Important: the windowsill should not close the battery. Disrupted air circulation will lead to the formation of condensate on the windows.

• Having accurate dimensions, the window sill is cut into the necessary parameters, taking into account protrusions along the walls by 2-4 cm on each side. If the window opening has a complex configuration, first a layout is cut out on the cardboard and try on. If everything is suitable, then the circuit is transferred to the panel.
• If the house is not new, and the opening is much lower than the groove under the frame of the plastic window, which is provided for the windowsill, wooden are placed first to the desired height. Then the prepared window sill is inserted into the groove between the window profile and foam to a depth of 2 cm.
• After that, using the level, they begin to regulate its evenness. You can do higher or lower by means of thin wooden wedges, which either raise or lower the window sill to the desired height. They have them at a distance of 30-40 cm from each other. In the future, they will remain inside the design and will play the role of holding elements.

Tip: install the windowsill with a slight slope towards the room, literally 5 mm. This will allow the condensate to slide, and not stay at the frame.

• Then it is necessary to disconnect the space under the windowsill. It is best to use a two -component foam that does not expand. When using the usual one, you will have to fill the surface of the window sill with heavy loads. To do this, put heavy bags with building mixtures, large cans of water, etc.
• After a day, the load can be removed, and the excess foam can be cut off with a clerical knife.
• As the final stage, decorative plugs are put on the sides of the window sills.

• The location of the window sill to the internal slopes of plastic windows is covered with corners.

• The process of polymerization (solidification) of the mounting foam is much faster in the humid environment. Therefore, before filling the space under the windowsill of the foam, it is wetted from a spray gun or any other sprayer.
• It is not recommended to fill too much foam. Since it has the properties of expanding several times and can push the window sill up, despite the load. To avoid this, small gaps are left between the freshly reduced stripes of the foam, which are guaranteed to close during the expansion.
• If there is no way to start the window sill panel into slopes and under the window profile, then it is adjusted perfectly for sure. All joints are treated with a colorless silicone sealant.
