  • resistant to mechanical loads and moisture;
  • not subjected to ultraviolet radiation;
  • It looks aesthetically and durable.

A successful and long-lasting installation of PVC window sills depends on understanding the various types that are available and adhering to the GOST installation guidelines. To make sure that your window sills not only look great but also perform flawlessly over time, this guide will simplify the key installation standards and break down the various PVC window sill options.

How and what are window sills for PVC windows made from?

The plastic that is used to make window sill boards is very strong. Regardless of the manufacturing company that produced the model, the PVC window sill’s design features are constant despite variations in appearance, parameters, and performance characteristics.

The products’ material and design are conventional:

  • The base is a hollow panel with a wall thickness of 1.5 to 3.0 mm.
  • The inner part of the window sill board is filled with stiffening ribs, which act as supports and provide mechanical strength. The quality of the product depends on the number of ribs, therefore, the more of them, the higher the rigidity index, which means the board can withstand heavy loads and not deform.
  • Smooth or rough (textured) coating. A distinctive feature of a smooth surface is the need for constant care, since the touch of fingers leaves marks that reduce aesthetic values. But such marks can be easily removed with a damp cloth soaked in soapy water. A rough matte surface does not have this feature, but over time its pores fill with dirt, which cannot be removed by simply wiping with a napkin, which means you will have to put in more effort.

A variety of sizes are available for PVC plastic window sills:

  • The length of the panels is up to 6000 mm;
  • Width – from 100 to 800 mm in increments of 50 mm.
  • Board thickness – from 20 mm.

Because they are composed of rigid PVC, modern window sill boards have a high strength and resistance to wear. They are shaped differently.

Kapinos in a plastic window sill

The term "free hanging edge" refers to the rounded portion of the window sill known as the kapinos. Because the slab’s edges are specifically rounded on the front or sides,

  • The thickness of the board visually increases;
  • Aesthetic indicators improve;
  • The degree of safety increases, since there are no sharp corners;
  • A special “trick” appears in interior design.

Producers take great pride in their work and give careful consideration to the aesthetic qualities of PVC window sill boards, which include capsinos. For this reason, a model with the appropriate parameters can always be found. Certain manufacturers make window sill boards that have two capinos on them.

Installation of plastic window sills in accordance with GOST

A plastic window sill can be installed in a few different ways. In essence, the products are installed so that the board is wider than the opening and fits into the wall on both sides to a small depth (between 1.5 and 3 cm). In addition to helping to strengthen and fix it better, the product should be wider and longer than the space beneath the window where it will be installed. This will also make it look much better from an aesthetic standpoint.

Installation stages

  1. Recesses in the slopes are made using a chisel and a hammer; you can also use another suitable tool.
  2. The window sill board is placed under the frame by about 1 cm. It happens that there is a large gap between the panel and the bottom of the opening, but it can be reduced using cement mortar, leaving 5-10 mm to run the board.
  3. Before proceeding with installation, the site should be cleared of debris and dust, and then checked for unevenness, so a building level will be required. Cement mortar is used to level the surface.
  4. When the site is prepared, you can begin installing the window sill board.
  5. When the board is completely installed, the protective covering is removed and the unsightly ends are covered with decorative caps, which are best purchased immediately.

Window sill installation is a fairly easy task; professional skills are not required. Accuracy and adherence to specific guidelines are the primary requirements:

  • Do not press hard on the surface when sawing, this will help avoid deformation and chips.
  • Not rush and saw it after everything is extinct to accuracy.

This will even assist the non-professor in completing tasks neatly and effectively, which will be essential for a lengthy tenure. A construction solution, special glue (referred to as "liquid nails"), mounting foam, or metal fasteners (profiles) on screws are used to install the PVC mounting board in GOST.

It is most convenient to fill the empty space beneath the installed windowsill with mounting foam.

Standard PVC Sill Ensure it"s level and securely fixed. Follow GOST for measurements and sealant use.
Insulated PVC Sill Check for proper insulation. Install with the correct thickness and seal gaps as per GOST.

You can make sure that your window sills are not just practical but also long-lasting and visually beautiful by being aware of the different kinds of PVC window sills and following installation guidelines such as GOST.

Appropriate installation is equally important since it determines the lifespan and performance of the sill. By adhering to GOST guidelines, the likelihood of issues later on is reduced and a professional and dependable setup is achieved.
