Despite the fact that polyurethane foam has not existed for so long on the consumer market, it is in very high demand among both professionals and amateurs. This is due to the fact that this sealant is very easy to use and highly effective in its functionality.

Mounting foam is produced in cylinders, the volume of which, as a rule, is 1 liter. 1/4 of the cylinder is filled with compressed gas, and the rest is filled with a special polyurethane component. Basically, the foam is designed to fill various cracks, chips, holes and other voids that need to be closed.

Based on the characteristics, the correct name for this material is polyurethane foam. Today the market is filled with various types of substances used for hermetic sealing of joints obtained during the installation of doors, windows, etc., but it is this foam that is the easiest, simplest and most effective method for such purposes. It stands out from other materials in that it does not allow air to pass through, is very resistant to external loads (such as wind or mechanical stress), is very tight, easy to use and affordable in price categories. However, its usein too large volumes can lead to sad consequences.

a substance called polyurethane foam. Initially, it is made from the following components: polyisocyanate, catalysts that accelerate the chemical process, a propane-butane mixture, as well as those materials that increase fire resistance. It is divided into two types: one-component and two-component. In addition, there is a winter polyurethane foam and summer, as well as household and professional. They differ from each other in terms of fire resistance.

When polyurethane foam first appeared on the market and builders began to use it, it immediately attracted the attention of specialists with such characteristics as sound insulation, high sealing properties, thermal insulation, and assembly properties. But in order for the use of polyurethane foam to be beneficial, it must be used in accordance with technological recommendations.

Choose the right one

Today, there are many manufacturers of polyurethane foam, as well as its various varieties with different characteristics. When deciding which one to purchase, there are a few things to keep in mind. For example, the indicator of the volume of foam output, which is indicated on the cylinders, is not a defining criterion. This is due to the fact that this indicator indicates the amount of a substance thatobtained under ideal environmental conditions: a certain air temperature, humidity, pressure, etc. The working environment on construction sites or garden plots can vary significantly, which means that professional polyurethane foam is not suitable for everyone. In addition, remember that the volume of this material at the exit is always about a third more than amateur sealant. Also, when choosing a foam canister, pay attention to the weight of the canister itself. His standard is 900 grams.
