Reliable plastic window sill

We live in an amazing time, when the words "repair" and "construction" are heard on every corner. One of the reasons for their so high popularity is the need to reduce heat losses during the cold season, which saves on paying for utilities. And without repairing the house is impossible.

It is known that the lion's share of thermal energy goes through the windows. And since many old houses still have old wooden window constructions that do not meet modern requirements for heat and sound insulation, it is quite clear that residents are actively changing them to metal-plastic windows. Surprisingly, when there is a discussion with the consultant about the equipment and the cost of the window, few people pay special attention to what kind of plastic windowsill will be included. And in vain! This is a big mistake. Although more often plastic windowsills are ordered for the remainder of the amount planned for the purchase of the entire window structure, it is not recommended to do so. At least because this, at first glance, a trifle, can both make the window invisible, and attract excessive attention to it.

This article will discuss the importance of this element, as well as some of the features of its selection and installation.

Plastic window sill and its advantages

This product serves to hide the lower part of the window opening, giving it a finish. This is his only purpose. It is necessary to understand that it does not perform any support functions. Consequently, the plastic window sill, which most installers offer today, is quite acceptable. Currently, the market offers several solutions. The plastic window sill, which can now be safely called a mass product, has a rough surface. Due to this, the probability of scratches is minimized, since the moving object slides along the points-protrusions, leaving no traces. It should be noted that there are varieties with glossy coating. A vivid example can serve as window sills Danke.

The basis is extruded polyvinyl chloride. The upper layer is made of a denser millimeter layer, subjected to coextrusion and laminated. The overall density of the product is such that it is quite difficult to break it. Thanks to the honeycomb structure (a set of cells with stiffeners), plastic windowsills have high thermal insulation properties. In addition, one of their undeniable advantages is the ability to install in rooms with a high level of humidity.

Reliability

Sometimes you can hear unflattering reviews about similar products made of plastic. However, most often problems in operation arise due to errors committed at the stage of installation. After the installation foam appeared, the installation process was much simpler: the need for "tricky" attachments disappeared, productivity increased. However, very few people know that between the wall-base and the underside of the windowsill, a distance of no more than 4 cm is allowed. This is quite enough for foam. But in most cases this distance is much greater. Sometimes its value reaches 10-15 cm. Of course, the window sill will not go anywhere, being installed in this way, but it will not withstand the heavy load. A layer of frozen foam can simply be poured. Enough to lean on, transferring part of the weight to the product, and the offset is ensured. Therefore, in those cases where the gap is too large, it must be reduced immediately before installing the window - brick it or pour cement mortar.
