Mounting foam - features and characteristics

Despite the fact that the mounting foam does not exist for so long in the consumer market, it is in great demand among professionals and amateurs alike. This is due to the fact that this sealant is very simple to use and very effective in its functionality.

Form of issue

The assembly foam is produced in cylinders, the volume of which, as a rule, is 1 liter. At 1/4 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 joints obtained when installing doors, windows, etc., but this foam is the easiest, simple and effective method for such purposes. It stands out among other materials in that it does not allow air to pass through, is very resistant to external loads (such as wind or mechanical influences), is very tight, easy to use and is available in price categories. However, using it in too large amounts can lead to unfortunate consequences.

Mounting foam - characteristic

When the foam solidifies, it is inherently converted into a chemically stable A substance called polyurethane foam. Initially, it is made from the following components: polyisocyanate, catalysts, accelerating chemical process, propano-butane mixture, as well as those materials that increase the resistance to fire. It is divided into two types: one-component and two-component. In addition, there is winter mounting foam and summer, as well as household and professional. They differ from each other in the degree of fire resistance.

When the assembly foam only appeared on the market and it was used by builders, it immediately attracted the attention of specialists with such characteristics as sound insulation, high sealing properties, thermal insulation, installation properties. But that the use of polyurethane foam benefits, it is necessary to use it, observing technological recommendations.

We choose correctly

To date, there are many manufacturers of mounting foam, as well as its various varieties with different characteristics. When you decide which one to purchase, it is worth considering some recommendations. For example, the foam output volume indicator, which is indicated on the cylinders, is not the determining criterion. This is due to the fact that this indicator indicates the amount of substance that is obtained under ideal ambient conditions: a certain temperature of air, humidity, pressure, etc. Working conditions on construction sites or garden sites can vary significantly, which means that professional installation foam does not suit everyone. In addition, remember that the volume of this material at the outlet is always greater than the amateur sealant by about a third. Also, when choosing a can of foam, pay attention to the weight of the cylinder itself. Its standard is 900 grams.
