We live in an amazing time when the words "repair" and "construction" are heard on every corner. One of the reasons for their high popularity is the need to reduce heat loss during the cold season, which allows you to save on utility bills. And without repair it is impossible to insulate the house.
It is known that the lion's share of thermal energy goes through windows. And since many houses still have old wooden window structures that do not meet modern requirements for heat and sound insulation, it is quite understandable that residents are actively replacing them with metal-plastic windows. Surprisingly, when there is a discussion with a consultant about the configuration and cost of a window, rarely does anyone pay special attention to what kind of plastic window sill will be included. But in vain! This is a big mistake. Although most often plastic window sills are ordered for the remainder of the amount planned for the purchase of the entire window structure, this is not recommended. If only because this, at first glance, a trifle, can both make the window invisible and draw undue attention to it.
This article will discuss the importance of this element, as well as some features of its choice andmounting.
Plastic window sill and its advantages
This product serves to hide the lower room part of the window opening, giving it completeness. This is his only purpose. It must be understood that it does not perform any supporting functions. Therefore, the plastic window sill that most installers offer today is quite acceptable. The market currently offers several solutions. A plastic window sill, which today can already be safely called a mass product, has a rough surface. Thanks to this, the likelihood of scratches is minimized, since the object being moved slides over the protrusion points without leaving marks. It is worth noting that there are varieties with a glossy finish. Danke window sills are a prime example.
The basis is extruded polyvinyl chloride. The top layer is made with a denser millimeter layer, co-extrusioned and laminated. The overall density of the product is such that it is quite difficult to break it. Due to the honeycomb structure (a set of cells with stiffeners), plastic window sills have high heat-insulating 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 bad reviews about such plastic products. However, most often problems during operation arise due to errors made at the installation stage.errors. After the appearance of mounting foam, the installation process was greatly simplified: the need for "tricky" fasteners disappeared, and work productivity increased. However, few people know that a distance of no more than 4 cm is allowed between the base wall and the underside of the window sill. 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 a large load. A layer of frozen foam can simply be squeezed through. It is enough to lean on, transferring part of the weight to the product, and the displacement is provided. Therefore, in cases where the gap is too large, it must be reduced immediately before installing the window - lay brick or pour cement mortar.
