Quickly developing technical progress allows you to create such a huge number of building materials that often our eyes just run away from such a variety. This trend did not bypass thermal insulation materials. From the list of the most affordable and popular thermal insulation materials suitable for insulation of the screed, foam and polystyrene polystyrene can be distinguished. The characteristics and properties of these types of material are approximately the same, but at a price they may differ from each other.
Dear Sirs, if you are looking for quality windows for your home. Then we advise you to buy plastic ones by passing the link we specified. And also, there you can learn a lot of interesting things about installing plastic windows and learn how to install yourself.
Foam can be calmly attributed to the material from the category of budgetary. What cannot be said about the heater from extruded polystyrene foam: it belongs to more expensive and modern materials.
In terms of installation and use of both types of materials for thermal insulation of screed, their main difference from each other is that polystyrene foam has a much greater strength and wider range of sheets with the necessary quarters of the size. These indicators allow you to lay the material in one layer, and thanks to the quarters you can avoid small cold bridges at the joints between the sheets. Of course, it is possible to lay insulation in one layer only if this thickness is sufficient to insulate the room.
